7 Min Read Monitoring Microorganisms iss070e049644 (Dec. 30, 2023) — A set of the International Space Station's main solar arrays, slightly obscuring the smaller roll-out solar arrays, and the Kibo laboratory module with its exposed facility, a research platform that hosts external experiments, are pictured 261 miles above the Pacific Ocean. Credits: NASA Science in Space January 2024 Crew members on the International Space Station have a lot of company – millions of bacteria and other microbes. The human body contains 10 times more microbes than human cells, and bacteria and fungi grow in and on just about everything around us on Earth. Most bacteria are harmless, and many are beneficial or even essential to human functioning and well-being. But microgravity can make some microbes more likely to cause disease and bacteria and fungi may affect the function of spacecraft systems, by, for example, corroding metal. These organisms also could contaminate other planetary bodies that spacecraft and humans land on. Some microbes inevitably come along for the ride on crew members and cargo traveling to the space station, and it is important to identify and control those that may be harmful – especially in a closed environment like a spacecraft. Multiple investigations have tracked, identified, and analyzed the station’s tiniest residents to help keep crew members and equipment – and even other planets – safe from any potential threats. A current investigation, ISS Boeing Antimicrobial Coating, tests surface coatings designed to inhibit the growth of microbes to protect crew members and equipment on a spacecraft. On Earth, such coatings could help reduce diseases transmitted from touching surfaces in aircraft cabins, health care facilities, public transportation, and other settings. NASA astronaut Megan McArthur documents touch panels installed for the ISS Boeing Antimicrobial Coating investigation.NASA Microbial Observatory-1 was one of the first investigations to monitor the types of microbes present on the space station. Researchers produced the genomes of multiple microorganisms, including some that may act as pathogens and cause disease. Published results include a comprehensive catalog of bacteria and fungi1 deposited into the NASA GeneLab system. NASA astronaut Scott Kelly collects samples for Microbial Observatory-1.NASA The Microbial Tracking-2 investigation continued a series monitoring the types of microbes on the space station and attempted to catalog and characterize any with disease-causing potential. Researchers produced whole-genome sequences of 94 fungal strains2 and 96 bacterial strains of 14 species3. The data also revealed that Staphylococcus and Malassezia species were the most common bacteria and fungi, respectively, on the space station and that, overall, microorganisms associated with the human skin dominated the surface microbiome4. A Microbial Tracking-2 device collects air samples.NASA BioRisk-MSV, a long-running Roscosmos investigation, examined physical and genetic changes in bacteria and fungi on interior and exterior surfaces of the space station. Researchers found that microorganisms not only survive in this extreme environment but retain their reproductive ability as well. Most microorganisms also exhibited increased biochemical activity and resistance to antibiotics5. These findings have implications for developing planetary quarantine methods and biomedical safety systems for future missions. The TEST investigation from Roscomos examined samples from the exterior surface of the space station and in life support systems. This work demonstrated that it was possible to collect data on viable microorganisms from open space and identified specific non-spore-forming bacteria found there6. Researchers also found land and marine bacteria in cosmic dust samples collected during a spacewalk. These microbes may transfer from the upper atmosphere via the global electric circuit (a continuous movement of electric charge carriers such as ions) or they may have originated in space7. NASA’s ISS External Microorganisms plans to continue this work, collecting samples near life support system vents outside the station to examine whether the spacecraft releases microorganisms and, if so, how many and how far they may travel. Myco, an investigation from JAXA (Japan Aerospace Exploration Agency), evaluated whether fungi inhaled by crew members or that adhere to their skin can act as allergens. The data revealed an increased relative abundance of a common fungus associated with seborrheic dermatitis (an itchy skin rash), and the presence of several types of fungi not common on the skin8. Results also showed an abundance of a yeast that may have adhered to the skin of some crew members preflight, suggesting that a specific or uncommon microorganism can proliferate in a closed environment. This study was the first to reveal changes over time in the skin fungal microbiota of astronauts9. NASA astronaut Cady Coleman processes samples for the Myco Experiment. NASA JAXA also conducted a series of experiments, Microbe-I, Microbe-III, and Microbe-IV, monitoring the abundance and diversity of fungi and bacteria in Kibo, the station’s Japanese Experiment module. This work resulted in multiple publications reporting on the type and numbers of microorganisms detected10,11. ISS Internal Environments provided a baseline of the contaminants on the space station. These data provide insight into the microbes present from the initial stages of construction through ongoing habitation of the orbiting lab. This and other research on the microorganisms in and around the space station are helping to ensure that crew members remain in safe company on current and future missions.

One of the ways NASA helps is through its Small Business Technology Transfer (STTR) program, which supports small businesses, and their research institution partners during early-stage research and development on a range of technologies that can benefit all. After proving their concepts during Phase I, and finalizing negotiations, NASA announced Thursday 21 small businesses will receive Phase II awards worth up to $850,000 each. The funds will go toward developing, demonstrating, and delivering innovative technologies over the next 24 months, bringing them one step closer to infusion into a NASA mission or commercialization in the marketplace. Each small business will collaborate with a research institution such as a university or Federally Funded Research and Development Center on their work—a requirement of STTR and a key differentiator from its sister program, Small Business Innovation Research (SBIR). “The STTR program exists to unlock the power and innovative thinking enabled by partnership between small businesses and research institutions, said Jenn Gustetic, director of Early Stage Innovation and Partnerships under the Space Technology Mission Directorate (STMD) at the NASA Headquarters in Washington. “NASA is committed to creating equitable opportunities and removing barriers for underrepresented audiences, so we’re proud that in this batch of awards, one-third of the partnering research institutions are Minority Serving Institutions (MSIs).” One of the awardees is SSS Optical Technologies, LLC, a Huntsville, Alabama, small business partnering with Oakwood University, a Historically Black Colleges and University also based in Huntsville. Together they will use the Phase II award to develop an innovative protective coating that absorbs damaging UV radiation and converts it into energy to power solar cells. The team prepared for their journey by participating in M-STTR—now the MUREP Partnership Learning Award Notification (MPLAN)—an initiative that connects MSIs with NASA to maximize the potential for long term collaborations and enhance future funding opportunities. Building off that early success, they won an STTR Phase I award, during which they demonstrated a 5% gain in efficiency while reducing radiation damage by 400%. The team will now focus their Phase II period on optimizing coating factors (composition, structure, and application method) for better efficiency and operational lifetime. If successful, their technology could find use in NASA’s Advanced Solar Sailing Technologies arena or in solar panels used in the commercial market. “Our program is in a unique position to support small businesses and their research institution partners to de-risk their technologies with funding and guidance,” said Jason Kessler, program executive for NASA’s SBIR/STTR program. “We want these awards to give each team the backing needed to showcase the impact the technologies can have inside and outside NASA’s walls.” This includes small businesses like Air Company Holdings, whichwas selected for a Phase II award to develop an alternative to fossil fuels. Based in Brooklyn, New York, the company is partnering with New York University to create a carbon dioxide hydrogenation technology that NASA can use to produce sustainable rocket fuel. The team will use their Phase II period to expand on the process model created in Phase I and optimize their fuel production and downstream processing, ensuring the produced fuel meets international standards. In addition to use as rocket fuel, this sustainable fuel could be used on Earth to address greenhouse gas emissions in the aviation industry or on Mars to produce a stable and storable fuel in-situ—using only the Martian atmosphere, water, and solar photovoltaic electricity—which could be used to power habitats, and more.

Overview As NASA’s Tracking and Data Relay Satellite (TDRS) constellation approaches retirement, partnerships with commercial industry will play a critical role in the development of future space communications and navigation architecture. Over the next decade, NASA missions will transition towards adopting commercial space-based relay services to fulfil their near-Earth communications needs. The Space Communications and Navigation (SCaN) program is working to ensure that future missions will continue to have reliable, resilient space and ground communications and navigation infrastructure. Wideband polylingual terminals could become a key technology supporting that infrastructure, by providing seamless roaming capabilities that could allow missions to receive communication signals from multiple SATCOM service providers through the use of software defined radios (SDR). Developed over the last decade, SDR technology enables waveform change in-orbit, allowing for the adoption of new and evolving commercial services by missions as they become available. Near Space Network antennas at the Alaska Satellite Facility in Fairbanks, Alaska.NASA Interoperability to Advance Science The goal of NASA’s Wideband User Terminal project is to provide interoperability between government and commercial owned networks for near-Earth services in the near-term by leveraging traditional NASA assets with new commercial infrastructure. Cellphone providers adopted roaming technology long ago, allowing devices to jump from network to network without interrupting service. Wideband terminals aim to enable similar roaming capabilities for space communications applications, a capability that has not been available to missions in the past. Wideband interoperability technology was developed and tested at NASA’s Glenn Research Center in Cleveland, Ohio, where the first successful test of roaming between multiple network providers was conducted in 2021. Commercialization Transition Interoperability between industry and government owned network providers could play a key role in NASA’s transition towards commercialization. NASA has relied on the TDRS system to provide near-constant communication links between the ground and satellites in low-Earth orbit for almost 40 years, but the infrastructure was not originally designed for interoperability between networks. SCaN is developing wideband technology to help the mission user community transition towards relying on commercial providers, by providing the safeguard option of connecting to the reliable TDRS network while private industry continue to develop and mature their space-based services over the next decade. There are numerous potential benefits of providing missions with interoperability between NASA’s legacy TDRS networks and new commercial satcom services, including reducing the risk of data loss and communication delays. Providing missions with a selection of network providers can also help avoid vendor lock-in and keep mission execution on schedule when unexpected circumstances arise. PExT Demonstration The Polylingual Experimental Terminal at Johns Hopkins University​Johns Hopkins University Applied Physics Laboratory NASA’s Wideband Terminal Project is collaborating with Johns Hopkins University Applied Physics Laboratory to test the prototype Polylingual Experimental Terminal (PExT). Mission objectives include demonstrating interoperability through contact and link management, and forward and return link data flow while roaming between NASA’s TDRS network and three commercial relay networks. The PExT Wideband Terminal will be the first flight demonstration of roaming across government and commercial networks from a single terminal. PExT will be integrated with a York Space Systems S-class Bus and launched on the SpaceX Falcon 9 Transporter-11 flight, currently planned for June 2024. The terminal will demonstrate various mission scenarios during its six-month testing period, including: self-pointing capabilities long-term schedule execution intra-/inter-network link handoff waveform adaptation and reloading command stack protection (crypto) link fault recovery The Wideband Project is currently providing opportunities for the mission user community to take part in extended operation experiments using Wideband technology. Please contact Wideband Technology Lead marie.t.piasecki@nasa.gov for more information. PExT Key Features Wide frequency covers the entire range of commercial and government Ka-Band allocations, including 17.7 GHz to 23.55 GHz Forward, and 27 GHz to 31 GHz Return Initial data rates reach up to 90 Mbps Forward and 375 Mbps Return. Future data rates are projected up to 490 Mbps Forward and 1 Gbps Return Supports both NASA and commercial waveforms – including DVB-S2 and CCSDS TDRSS The body-mounted 0.6-meter antennas are scalable for other missions Effective Isotropic Radiated Power (EIRP) 46.21 dBW minimum Gain to Noise G/T ration approximately 6dB/K Team members from the Polylingual Experimental Terminal project and Applied Physics Laboratory stand next to PExT after preparing the terminal for vibration testing.

Data collected from the test series will be used to certify production of new RS-25 engines by lead contractor Aerojet Rocketdyne, an L3Harris Technologies company, to help power the SLS rocket on future Artemis missions to the Moon and beyond, beginning with Artemis V. Teams are evaluating the performance of several new engine components, including a nozzle, hydraulic actuators, flex ducts, and turbopumps. The current series is the second and final series to certify production of the upgraded engines. NASA completed an initial 12-test certification series with the upgraded components in June 2023. During the Jan. 17 test, operators followed a “test like you fly” approach, firing the engine for the same amount of time – almost eight-and-a-half minutes (500 seconds) – needed to launch SLS and at power levels ranging between 80% to 113%. The Jan. 17 test comes three months after the current series began in October. During three tests last fall, operators fired the engine for durations from 500 to 650 seconds. The longest planned test of the series occurred on Nov. 29 when crews gimbaled, or steered, the engine during an almost 11-minute (650 seconds) hot fire. The gimbaling technique is used to control and stabilize SLS as it reaches orbit. Each SLS flight is powered by four RS-25 engines, firing simultaneously during launch and ascent to generate over 2 million pounds of thrust. The first four Artemis missions with SLS are using modified space shuttle main engines that can power up to 109% of their rated level. The newly produced RS-25 engines will power up to the 111% level to provide additional thrust. Testing to the 113% power level provides an added margin of operational safety. With the completion of the test campaign in 2024, all systems are expected to be “go” for production of 24 new RS-25 engines for missions beginning with Artemis V. Through Artemis, NASA will establish a long-term presence at the Moon for scientific exploration with commercial and international partners, learn how to live and work away from home, and prepare for future human exploration of Mars.

5 min read Laser Instrument on NASA’s LRO Successfully ‘Pings’ Indian Moon Lander For the first time at the Moon, a laser beam was transmitted and reflected between an orbiting NASA spacecraft and an Oreo-sized device on ISRO’s (Indian Space Research Organisation) Vikram lander on the lunar surface. The successful experiment opens the door to a new style of precisely locating targets on the Moon’s surface. At 3 p.m. EST on Dec. 12, 2023, NASA’s LRO (Lunar Reconnaissance Orbiter) pointed its laser altimeter instrument toward Vikram. The lander was 62 miles, or 100 kilometers, away from LRO, near Manzinus crater in the Moon’s South Pole region, when LRO transmitted laser pulses toward it. After the orbiter registered light that had bounced back from a tiny NASA retroreflector aboard Vikram, NASA scientists knew their technique had finally worked. ISRO’s (Indian Space Research Organization) Vikram lander, with a NASA retroreflector on it, touched down on the Moon on Aug. 23, 2023. The camera aboard NASA’s LRO (Lunar Reconnaissance Orbiter) took this picture four days later. The lander is in the center of the image, its dark shadow visible against the bright halo around it. The halo formed after rocket plume interacted with the fine-grained regolith (similar to soil) on the Moon’s surface. The image shows an area that’s 1 mile, or 1.7 kilometers, wide. NASA’s Goddard Space Flight Center/Arizona State University Sending laser pulses toward an object and measuring how long it takes the light to bounce back is a commonly used way to track the locations of Earth-orbiting satellites from the ground. But using the technique in reverse – to send laser pulses from a moving spacecraft to a stationary one to determine its precise location – has many applications at the Moon, scientists say. “We’ve showed that we can locate our retroreflector on the surface from the Moon’s orbit,” said Xiaoli Sun, who led the team at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, that developed the retroreflector on Vikram as part of a partnership between NASA and ISRO. “The next step is to improve the technique so that it can become routine for missions that want to use these retroreflectors in the future.” Only 2 inches, or 5 centimeters, wide, NASA’s tiny but mighty retroreflector, called a Laser Retroreflector Array, has eight quartz-corner-cube prisms set into a dome-shaped aluminum frame. The device is simple and durable, scientists say, requiring neither power nor maintenance, and can last for decades. Its configuration allows the retroreflector to reflect light coming in from any direction back to its source. Only 2 inches, or 5 centimeters, wide, NASA’s Laser Retroreflector Array has eight quartz-corner-cube prisms set into a dome-shaped aluminum frame. This configuration allows the device to reflect light coming in from any direction back to its source. NASA’s Goddard Space Flight Center Retroreflectors can be used for many applications in science and exploration and, indeed, have been in use at the Moon since the Apollo era. By reflecting light back to Earth, the suitcase-size retroreflectors revealed that the Moon is moving away from our planet at a rate of 1.5 inches (3.8 centimeters) per year. This new generation of tiny retroreflectors has even more applications than their larger predecessors. On the International Space Station, they’re used as precision markers that help cargo-delivery spacecraft dock autonomously. In the future, they could guide Artemis astronauts to the surface in the dark, for example, or mark the locations of spacecraft already on the surface, helping astronauts or uncrewed spacecraft land next to them. But there’s more work to do before retroreflectors can light up the Moon. The biggest hurdle to their immediate adoption is that LRO’s altimeter, which has operated for 13 years beyond its primary mission, is the only laser instrument orbiting the Moon for now. But the instrument wasn’t designed to pinpoint a target; since 2009, the altimeter – called LOLA – has been responsible for mapping the Moon’s topography to prepare for missions to the surface. “We would like LOLA to point to this Oreo-sized target and hit it every time, which is hard,” said Daniel Cremons, a NASA Goddard scientist who works with Sun. It took the altimeter eight tries to contact Vikram’s retroreflector. LOLA works by dispatching five laser beams toward the Moon and measuring how long it takes each one to bounce back (the quicker the light returns, the less distance between LOLA and the surface, and thus the higher the elevation in that area). Each laser beam covers an area 32 feet, or 10 meters, wide, from a 62-mile, or 100-kilometer, altitude. Because there are large gaps between the beams, there is only a small chance that the laser pulse can contact a retroreflector during each pass of the lunar orbiter over the lander. Altimeters are great for detecting craters, rocks, and boulders to create global elevation maps of the Moon. But they aren’t ideal for pointing to within one-hundredth of a degree of a retroreflector, which is what’s required to consistently achieve a ping. A future laser that slowly and continuously rakes the surface without any gaps in coverage would help tiny retroreflectors meet their potential. For now, the team behind NASA’s miniature retroreflectors will continue to use LRO’s laser altimeter to help refine the position of targets on the surface, especially landers. Several NASA retroreflectors are slated to fly aboard public and private Moon landers, including one on JAXA’s (Japan Aerospace Exploration Agency) SLIM lander, due to land on the Moon on Jan. 19, 2024, and one built by Intuitive Machines, a private company scheduled to launch its spacecraft to the Moon in mid-February. Intuitive Machines will carry six NASA payloads, including the retroreflector, under NASA’s Commercial Lunar Payload Services (CLPS) initiative.

28 Min Read The Marshall Star for January 17, 2024 ‘Be King’: Team Redstone Invites All to Honor Civil Rights Icon’s Legacy By Jessica Barnett Several accomplished speakers took to the stage Jan. 11 at NASA’s Marshall Space Flight Center to share how Martin Luther King Jr.’s life and legacy helped shape their lives. The event was hosted by Marshall’s ODEO (Office of Diversity and Equal Opportunity), along with the FBI and U.S. Army, in the center’s Activities Building 4316 as a way of honoring King, a minister and activist from Atlanta who rose to national prominence as a key figure in the civil rights movement of the 1950s and 1960s. King would have been 95 on Jan. 15. Several guest speakers took to the stage Jan. 11 at NASA’s Marshall Space Flight Center to share how Martin Luther King Jr.’s life and legacy impacted them personally, as well as how others can continue his legacy by being like King today. Pictured here, from left, are Tora Henry, director of Marshall’s Office of Diversity and Equal Opportunity; Kenny Anderson, director of Huntsville City’s Office of Diversity, Equity & Inclusion; Jacquelyn Gates Shipe, CEO of Global Ties Alabama; Darell Ezell, social scientist, professor, administrator, and corporate strategist; Bryan Samuel, vice president of Diversity, Equity & Inclusion at the University of Alabama in Huntsville; and Larry Leopard, associate center director, technical, at Marshall. NASA/Alex Russell Marshall ODEO Deputy Director Carolyn Magsby and Associate Center Director-Technical Larry Leopard kicked off the event before welcoming Kenny Anderson, Huntsville City’s director of the Office of Diversity, Equity & Inclusion. Though the theme for the event was “It Starts with Me,” Anderson helped set the tone by encouraging everyone to honor King by “being King” and choosing peace, compassion, and education over violence, criticism, and ignorance. Following Anderson’s remarks, Bill Marks, who serves as deputy director of Marshall’s Office of Center Operations, moderated a panel featuring Darrell Ezell, a social scientist, administrator, professor, and corporate strategist; Jacquelyn Gates Shipe, CEO of Global Ties Alabama; and Bryan Samuel, vice president of Diversity, Equity & Inclusion at the University of Alabama at Huntsville.

Mentor and Michoud Assembly Facility integrations lead Cynthia Spraul, left, smiles with mentee, Marie Allain, project coordinator, at a holiday party in 2022. NASA/Courtesy of Marie Allain For some, a mentorship may seem daunting. A mentee looking for a mentor in a new environment can find it difficult to find someone they trust to guide their career and personal growth. Meanwhile, mentors may feel discouraged, thinking they might not have enough knowledge to be in their role. Hoping their experience can help others during National Mentor Month, Spraul and Allain shared their insight about finding and starting a mentorship. Spraul worked for Lockheed Martin at Michoud on the Space Shuttle Program’s External Tank for 20 years. For the past 17 years, she has worked for NASA at Michoud, where she is currently the integrations lead. “I work on strategic site management, resource management, and contract management,” Spraul said. Allain graduated with a bachelor’s degree in mechanical engineering from LSU (Louisiana State University) in 2021. “I got involved with the American Institute of Aeronautics and Astronautics at LSU, an aerospace professional society, which is how I really got into aerospace,” she said. Allain now works as a project coordinator on Spraul’s integrations team. She performs project management in the Michoud Directorate and contract administration along with Component Processing Facility management. Spraul was asked to coordinate the summer internship program at Michoud, which is how she got started as a mentor. Spraul was the program’s first mentor at MAF. So, when Allain approached her requesting mentorship, she gladly took her on. Question: What does mentorship mean to you? Spraul: Seeing someone’s interest in what you do, like Marie taking an interest in my past experience, reinvigorates my love for my job and my desire to work. Mentoring makes work fun for me again. I might be doing the same things, but since I’m teaching somebody while I’m doing it, I get to listen to myself when I talk. It makes me go, ‘Oh, wow, I really get to do this.’ I get excited about my work all over again. Allain: My mentor makes me feel like I’m starting my career with the insight a person at the peak of their career wishes they had when they started. This mentorship gives me an opportunity to start on the right foot. I get to start out with tools that will help me later down the line. It gives me the opportunity to glean a lot of insight from people who have been at Michoud for a long time. They know the history of the place firsthand. A lot of people in this office are getting near retirement, and before too long, we’re going to have a lot of information, a lot of our history, that’s lost. I get the opportunity to retain some of that history from somebody who experienced it firsthand. Question: What impact has mentorship had on you and your career? Spraul: Someone having an interest in what I’m doing is a catalyst for me and my own career growth. The more I get reinterested in what I’m doing, the more I ask myself, ‘What’s my next step and how do I get there?’ Especially because Allain’s watching me. It’s always better to perform when someone’s watching you. There’s a reason to do better and grow because young people are watching. I also tend to turn my focus on the coming generations, because they’re going to be here when I’m gone. Allain: Before going into this mentorship, I struggled visualizing what my career could look like. Especially coming right out of college, nobody knows what jobs actually exist. Spraul knows what our organization is and what exists in it, and what it’s like to work in different roles in the organization. The kind of insight she provided completely changed how I feel about my career. I have an actual vision of where I’m headed. Beforehand, I felt I was somewhat free floating in space. Question: How did you find and connect with your mentor/mentee? Spraul: After mentoring college interns over the years, I’m always excited when I learn something new from them. When Marie came to me requesting mentorship, she had already taught me so many things that I thought it was a great idea to expand our dialogue. Allain: It was natural for us.After the first few months of working together on projects, we would have lunch together. We’d spend some time together and talk. I started to realize she and I have a lot in common. Question: What steps did you take to approach your mentor/mentee to initiate the partnership? Allain: I started asking her for insight about her experience and her career. The mentorship relationship developed from there. It started with discussions during lunch and developed into conversations about everything from work stories to life experience. Spraul: Allain asked introspective questions that would lead us on a good tangent while we worked together as well. We also started staying after work so I could have longer conversations with Allain about a path for her future. Question: What advice do you have for someone else considering finding or being a mentor? Allain: For mentees, find somebody you look up to in your organization and just ask. Most potential mentors see it as a huge compliment. The worst thing that can happen is being told no. I think most people at NASA would say yes. Don’t feel like you’re putting somebody out by asking them to mentor you. Also, don’t sit around assuming mentors are going to come to you. Spraul: I would suggest that mentees observe other people above them. Mentees should watch how potential mentors conduct themselves to see who they would like to model themselves after. For mentors, a lot of work goes into being mentor. It’s more than showing up. Be prepared by knowing what you’re going to have your mentee do and try. Being a mentor does take some work, but you receive tenfold in your own career and the enjoyment of your day. Don’t be afraid is my best advice. Even showing up is valuable to the mentee. You’ll get results from anything else you put into it. Editor’s note: This is the first in a Marshall Star series during National Mentor Month in January.

To safely carry out these missions, agency leaders are adjusting the schedules for Artemis II and Artemis III to allow teams to work through challenges associated with first-time developments, operations, and integration. NASA will now target September 2025 for Artemis II, the first crewed Artemis mission around the Moon, and September 2026 for Artemis III, which is planned to land the first astronauts near the lunar South Pole. Artemis IV, the first mission to the Gateway lunar space station, remains on track for 2028. From left, Artemis II crew members CSA (Canadian Space Agency) astronaut Jeremy Hansen, and NASA astronauts Christina Koch, Victor Glover, and Reid Wiseman walk out of Astronaut Crew Quarters inside the Neil Armstrong Operations and Checkout Building to the Artemis crew transportation vehicles prior to traveling to Launch Pad 39B as part of an integrated ground systems test at Kennedy Space Center on Sept. 20, to test the crew timeline for launch day.NASA “We are returning to the Moon in a way we never have before, and the safety of our astronauts is NASA’s top priority as we prepare for future Artemis missions,” said NASA Administrator Bill Nelson. “We’ve learned a lot since Artemis I, and the success of these early missions relies on our commercial and international partnerships to further our reach and understanding of humanity’s place in our solar system. Artemis represents what we can accomplish as a nation – and as a global coalition. When we set our sights on what is hard, together, we can achieve what is great.” Ensuring crew safety is the primary driver for the Artemis II schedule changes. As the first Artemis flight test with crew aboard the Orion spacecraft, the mission will test critical environmental control and life support systems required to support astronauts. NASA’s testing to qualify components to keep the crew safe and ensure mission success has uncovered issues that require additional time to resolve. Teams are troubleshooting a battery issue and addressing challenges with a circuitry component responsible for air ventilation and temperature control. NASA’s investigation into unexpected loss of char layer pieces from the spacecraft’s heat shield during Artemis I is expected to conclude this spring. Teams have taken a methodical approach to understand the issue, including extensive sampling of the heat shield, testing, and review of data from sensors and imagery. The new timeline for Artemis III aligns with the updated schedule for Artemis II, ensures the agency can incorporate lessons learned from Artemis II into the next mission, and acknowledges development challenges experienced by NASA’s industry partners. As each crewed Artemis mission increases complexity and adds flight tests for new systems, the adjusted schedule will give the providers developing new capabilities – SpaceX for the HLS (human landing system) and Axiom Space for the next-generation spacesuits – additional time for testing and any refinements ahead of the mission. “We are letting the hardware talk to us so that crew safety drives our decision-making. We will use the Artemis II flight test, and each flight that follows, to reduce risk for future Moon missions,” said Catherine Koerner, associate administrator, Exploration Systems Development Mission Directorate at NASA Headquarters. “We are resolving challenges associated with first-time capabilities and operations, and we are closer than ever to establishing sustained exploration of Earth’s nearest neighbor under Artemis.” In addition to the schedule updates for Artemis II and III, NASA is reviewing the schedule for launching the first integrated elements of Gateway, previously planned for October 2025, to provide additional development time and better align that launch with the Artemis IV mission in 2028. NASA also shared that it has asked both Artemis human landing system providers – SpaceX and Blue Origin – to begin applying knowledge gained in developing their systems as part of their existing contracts toward future variations to potentially deliver large cargo on later missions. “Artemis is a long-term exploration campaign to conduct science at the Moon with astronauts and prepare for future human missions to Mars. That means we must get it right as we develop and fly our foundational systems so that we can safely carry out these missions,” said Amit Kshatriya, deputy associate administrator of Exploration Systems Development, and manager of NASA’s Moon to Mars Program Office at headquarters. “Crew safety is and will remain our number one priority.” NASA leaders emphasized the importance of all partners delivering on time so the agency can maximize the flight objectives with available hardware on a given mission. NASA regularly assesses progress and timelines and as a part of integrated programmatic planning to ensure the agency and its partners can successfully accomplish its Moon to Mars exploration goals. With Artemis, NASA will explore more of the Moon than ever before, learn how to live and work away from home, and prepare for future human exploration of the Red Planet. NASA’s SLS (Space Launch System) rocket, exploration ground systems, and Orion spacecraft, along with the human landing system, next-generation spacesuits, Gateway lunar space station, and future rovers are NASA’s foundation for deep space exploration. NASA’s Marshall Space Flight Center manages the SLS and HLS programs. NASA’s Michoud Assembly Facility, which is managed by Marshall, manufactures several Artemis components, including the SLS core stage. › Back to Top IXPE Helps Researchers Maximize ‘Microquasar’ Findings By Rick Smith The powerful gravity fields of black holes can devour whole planets’ worth of matter – often so violently that they expel streams of particles traveling near the speed of light in formations known as jets. Scientists understand that these high-speed jets can accelerate these particles, called cosmic rays, but little is definitively known about that process. Recent findings by researchers using data from NASA’s IXPE (Imaging X-ray Polarimetry Explorer) spacecraft give scientists new clues as to how particle acceleration happens in this extreme environment. The observations came from a “microquasar,” a system comprised of a black hole siphoning off material from a companion star. This composite image of the Manatee Nebula captures the jet emanating from SS 433, a black hole devouring material embedded in the supernova remnant which spawned it. Radio emissions from the remnant are blue-green, whereas X-rays combined from IXPE, XMM-Newton, and Chandra are highlighted in bright blue-purple and pinkish-white against a backdrop of infrared data in red. The black hole emits twin jets of matter traveling in opposite directions at nearly the speed of light, distorting the remnant’s shape. The jets become bright about 100 light years away from the black hole, where particles are accelerated to very high energies by shocks within the jet. The IXPE data shows that the magnetic field, which plays a key role in how particles are accelerated, is aligned parallel to the jet – aiding our understanding of how astrophysical jets accelerate these particles to high energies.X-ray: (IXPE): NASA/MSFC/IXPE; (Chandra): NASA/CXC/SAO; (XMM): ESA/XMM-Newton; IR: NASA/JPL/Caltech/WISE; Radio: NRAO/AUI/NSF/VLA/B.

Saxton. (IR/Radio image created with data from M. Goss, et al.); Image Processing: NASA/CXC/SAO/N. Wolk & K.Arcand The microquasar in question – Stephenson and Sanduleak 433, or SS 433 – sits in the center of the supernova remnant W50 in the constellation Aquila, some 18,000 light-years from Earth. SS 433’s powerful jets, which distort the remnant’s shape and earned it the nickname the “Manatee Nebula,” have been clocked at roughly 26% of the speed of light, or more than 48,000 miles per second. Identified in the late 1970s, SS 433 is the first microquasar ever discovered. IXPE’s three onboard telescopes measure a special property of X-ray light called polarization, which tells scientists about the organization and alignment of electromagnetic waves at X-ray frequencies. X-ray polarization helps researchers understand the physical processes taking place within extreme regions of our universe – such as the environment around black holes – and how particles get accelerated in these regions. IXPE spent 18 days in April and May of 2023 studying one such acceleration site in the eastern lobe of SS 433, where emissions are made by energetic electrons spiraling in a magnetic field – a process called synchrotron radiation. “The IXPE data show that the magnetic field near the acceleration region points in the direction the jets are moving,” said astrophysicist Philip Kaaret of NASA’s Marshall Space Flight Center, and principal investigator of the IXPE mission, along with lead author of a new paper about the findings at SS 433. “The high level of polarization seen with IXPE shows that the magnetic field is well ordered, with at least half of the field aligned in the same direction,” Kaaret said. That finding was unexpected, he said. Researchers have long theorized that the interaction between the jet and the interstellar medium – the environment of gas and dust between stars – likely creates a shock, leading to disordered magnetic fields. The data suggests a new possibility, Kaaret said – that the magnetic fields within the powerful jets may be “trapped” and stretched when they collide with interstellar matter, directly impacting their alignment in the region of particle acceleration. Since the 1980s, researchers have surmised that SS 433’s jets act as particle accelerators. In 2018, observers at the High-Altitude Water Cherenkov Observatory in Puebla, Mexico, verified the jets’ acceleration effect, and scientists used NASA’s NuSTAR (Nuclear Spectroscopic Telescope Array) and the European Space Agency’s XMM-Newton observatories to pinpoint the region of acceleration. As researchers continue to assess IXPE findings and study new targets in space, its data also could help determine whether the same mechanism acts to align magnetic fields in outflows expelled by a variety of phenomena – from black hole jets streaming away from supernova remnants to debris ejected from exploded stars such as blazars. “This very delicate measurement was made possible by the imaging capabilities of IXPE’s X-ray polarimeters, making possible the detection of the tenuous signal in a small region of the jet 95 light-years from the central black hole,” said Paolo Soffitta, Italian principal investigator for the IXPE mission. The new paper, detailing IXPE’s observations at SS 433, is available in the latest edition of The Astrophysical Journal. IXPE is a collaboration between NASA and the Italian Space Agency with partners and science collaborators in 12 countries. IXPE is led by Marshall.

Through tours, panels, and one-on-one discussions, the workshop provided an overview and best practices of what NASA does to prepare International Space Station payloads for operations, so commercial partners can leverage NASA’s knowledge and experience as they build their own space stations and presence in Low Earth orbit. NASA experts discuss International Space Station payload operations during a three-day workshop held Nov. 7-9 at NASA’s Marshall Space Flight Center. The workshop provided NASA’s commercial partners an overview and NASA’s best practices for preparing space station payloads for operations.NASA/Sherresa Lockett “We have so much history and knowledge, and we want to impart on them what we know so they can think about it, and see what applies to them and what doesn’t,” said Eleasa Kim, who serves as the Payload Operations Lead for NASA’s Commercial Low Earth Orbit Development Program, also known as CLDP, supporting Marshall’s Human Exploration Development and Operations Division. NASA’s CLDP is supporting the development of commercially owned and operated Low Earth orbit destinations from which NASA, along with other customers, can purchase services and stimulate the growth of commercial activities. As commercial Low Earth orbit destinations become available, NASA intends to implement an orderly transition from current space station operations to these new commercial destinations. More than 70 people joined the workshop in person and online. Attendees were able to listen to experts discuss a litany of topics, from a general overview of the payload life cycle to safety reviews and flight readiness checks to real-time support and anomaly response. Among the attendees, was John Selmarten, senior manager, Payload Project Management at Axiom Space. Selmarten said the workshop offered invaluable help to the company. “The CLDP workshop offered industry access to, and an overview of, NASA’s wide variety of subject matter experts, tools, and facilities currently utilized to operate payloads on the ISS,” Selmarten said. “This information is invaluable to Axiom Space as we begin the transformation of low-Earth orbit into a global marketplace through research, in-space manufacturing, and tech demos.” For Alex Stuetz and Denis Healy of Los Angeles-based aerospace company Vast, it was an amazing opportunity to hear from people with decades of experience. “I certainly benefited from the breadth of topics covered,” said Healy, who serves as Vast’s mission operations engineer II. “It wasn’t three or four very specific, niche areas, but there was a good scope of subjects covered, and the details and nuance as it relates to each.” The pair also took part in the tours and one-on-one discussions made available through the workshop. Kirt Costello, standing, speaks to a room of NASA’s commercial partners during the Payload Operations Workshop. Costello is the utilization manager for the commercial Low Earth Orbit Development Program.NASA/Jessica Barnett “It’s incredibly helpful to be able to have face-to-face conversations and get a tour of the facilities, to see the hardware,” said Stuetz, Vast’s mission manager. “It’s these types of events that really push everything forward rapidly and in a collaborative manner.” Marshall team members were equally excited to share their knowledge with NASA’s commercial partners. “It’s a chance to share and build something new, to continue the Low Earth orbit presence,” said Joe Kitchen, operations discipline lead for the Planning and Analysis Branch of the Payload Mission Operations Division at Marshall. “Commercializing is really the only way to enable it, so it’s cool to be part of this.” Marty O’Toole, the Starlab payloads lead on the Voyager team, also shared his appreciation for the MSFC Payload Ops team and the workshop. “It was a very informative briefing on all aspects of ISS payload operations, from early integration activities through planning, certification, real-time ops and return,” said O’Toole. “The presentation format with a group of experienced individuals assuming their CADRE (Cooperative Autonomous Distributed Robotic Exploration) roles helped to demonstrate and emphasize the detailed coordination needed across all the ops functions. This exercise stimulated lots of discussion and thinking about how Starlab can implement and streamline its operations program going forward.” Kim explained that the workshop is the first of its kind for her team, which spent three months preparing, including dry runs on each Friday of the final month leading up to the workshop. In addition to preparing tours and panels, they arranged social events, networking opportunities, case studies with filmed simulations, and more for the commercial partners.

NASA’s Cryo Efforts Beyond the Atmosphere Establishing sustained operations at the Moon and Mars presents a multitude of opportunities and challenges NASA has yet to encounter. Many of these activities require new technologies and processes to ensure the agency is prepared for its ambitious Artemis missions and those beyond. One of those challenges is working with cryogenic fluids, meaning fluids existing in a liquid state between minus 238 degrees Fahrenheit and absolute zero (minus 460 F). These fluids – liquid hydrogen (the most difficult to work with), methane, and oxygen – are vital to spacecraft propulsion and life support systems. The fluids may also be produced in the future on the lunar and Martian surfaces via ISRU (in-situ resource utilization). A 2019 image of the SHIIVER tank sitting inside the In-Space Propulsion Facility’s vacuum chamber at NASA’s Neil Armstrong Test Facility in Sandusky, Ohio. The tank was part of a Cryogenic Fluid Management project effort to test the tank at extreme temperatures and ensure the new technologies kept the propellants inside cold and in a liquid state.Credit: NASA Human exploration in deep space requires storing large amounts of cryogenic fluids for weeks, months, or longer, as well as transferring between spacecraft or fuel depots in orbit and on the surface. Each aspect is challenging, and, to date, large amounts of cryogenic fluids have only been stored for hours in space. Engineers working in NASA’s Cryogenic Fluid Management, or CFM, Portfolio – led by Technology Demonstration Missions within the Space Technology Mission Directorate and managed at the agency’s Glenn Research Center and Marshall Space Flight Center – are solving those issues ahead of future missions. “This is a task neither NASA, nor our partners, have ever done before,” said Lauren Ameen, deputy CFM Portfolio manager. “Our future mission concepts rely on massive amounts of cryogenic fluids, and we have to figure out how to efficiently use them over long durations, which requires a series of new technologies far exceeding today’s capabilities.” For a cryogenic fluid to be useable, it must remain in a frigid, liquid state. However, the physics of space travel – moving in and out of sunlight and long stays in low gravity – make keeping those fluids in a liquid state and knowing how much is in the tank complicated. The heat sources in space ­– like the Sun and the spacecraft’s exhaust – create a hot environment inside and around storage tanks causing evaporation or “boiloff.” When fluid evaporates, it can no longer efficiently fuel a rocket engine. It also increases the risk of leakage or, even worse, a tank rupture. Being unsure of how much gas is left in the tank isn’t how our explorers want to fly to Mars. Low gravity is challenging because the fuel wants to float around – also known as “slosh” – which makes accurately gauging the amount of liquid and transferring it very difficult. “Previous missions using cryogenic propellants were in space for only a few days due to boiloff or venting losses,” Ameen noted. “Those spacecraft used thrust and other maneuvers to apply force to settle propellant tanks and enable fuel transfers. During Artemis, spacecraft will dwell in low gravity for much longer and need to transfer liquid hydrogen in space for the first time, so we must mitigate boiloff and find innovative ways to transfer and measure cryogenic propellants.” NASA’s CFM portfolio encompasses 24 development activities and investments to reduce boiloff, improve gauging, and advance fluid transfer techniques for in-space propulsion, landers, and ISRU. There are four near-term efforts taking place on the ground, in near-Earth orbit, and soon on the lunar surface. Flight Demos In 2020, NASA awarded four CFM-focused Tipping Point contracts to American industry – Eta Space, Lockheed Martin, SpaceX, and United Launch Alliance – to assist in developing and demonstrating CFM technologies in space. Each company is scheduled to launch its respective demonstration in either 2024 or 2025, performing multiple tests using liquid hydrogen to validate technologies and processes. Radio Frequency Mass Gauge To improve gauging, NASA has developed RFMG (Radio Frequency Mass Gauges) to allow for more accurate fluid measurement in low-gravity or low-thrust conditions. Engineers do this by measuring the electromagnetic spectrum, or radio waves, within a spacecraft’s tank throughout the mission, comparing them to fluid simulations to accurately gauge remaining fuel. The RFMG has been proven in ground tests, sub-orbital parabolic flight, and on the International Space Station, and it will soon be tested on the Moon during an upcoming Commercial Lunar Payload Services flight with Intuitive Machines. Once demonstrated in the lunar environment, NASA will continue to develop and scale the technology to enable improved spacecraft and lander operations. Cryocoolers Cryocoolers act like heat exchangers for large propellant tanks to mitigate boiloff when combined with innovative tank insulation systems. With industry partners, like Creare, NASA has begun testing high-capacity cryocooler systems that pump the “working” fluid through a network of tubes installed on the tank to keep it cool. NASA plans to increase tank size and capabilities to meet mission requirements before conducting future flight demonstrations. CryoFill NASA is also developing a liquefaction system to turn gaseous oxygen into liquid oxygen on the surface of the Moon or Mars to refuel landers using propellant produced in situ. This approach uses various methods to cool oxygen down to critical temperature (at least minus 297 degrees Fahrenheit), where it condenses, turning from a gas to a liquid. Initial development and testing have proven NASA can do this efficiently, and the team continues to scale the technology to relevant tank sizes and quantities for future operations. Ultimately, NASA efforts to develop and test CFM systems that are energy-, mass-, and cost-efficient are critical to the success of the agency’s ambitious missions to the Moon, Mars, and beyond.

This research showed that the conditions for stellar conception in these exceptionally massive galaxies have not changed over the last ten billion years. These images represent a sample of galaxy clusters that are part of the largest and most complete study to learn what triggers stars to form in the universe’s biggest galaxies. Clusters of galaxies are the largest objects in the universe held together by gravity and contain huge amounts of hot gas seen in X-rays. This research, made using Chandra and other telescopes, showed that the conditions for stellar conception in these exceptionally massive galaxies have not changed over the last ten billion years. In these images, X-rays from Chandra are shown along with optical data from Hubble.X-ray: NASA/CXC/MIT/M. Calzadilla el al.; Optical: NASA/ESA/STScI; Image Processing: NASA/CXC/SAO/N. Wolk & J. Major Galaxy clusters are the largest objects in the universe held together by gravity and contain huge amounts of hot gas seen in X-rays. This hot gas weighs several times the total mass of all the stars in all the hundreds of galaxies typically found in galaxy clusters. In the four galaxy cluster images in this graphic, X-rays from hot gas detected by Chandra are in purple and optical data from NASA’s Hubble Space Telescope, mostly showing galaxies in the clusters, are yellow and cyan. In this study, researchers looked at the brightest and most massive class of galaxies in the universe, called BCGs (brightest cluster galaxies), in the centers of 95 clusters of galaxies. The galaxy clusters chosen are themselves an extreme sample – the most massive clusters in a large survey using the SPT (South Pole Telescope), with funding support from the National Science Foundation and Department of Energy – and are located between 3.4 and 9.9 billion light-years from Earth. The four galaxy clusters shown here at located at distances of 3.9 billion (SPT-CLJ0106-5943), 5.6 billion (SPT-CLJ0307-6225), 6.4 billion (SPT-CLJ0310-4647) and 7.7 billion (SPT-CLJ0615-5746) light-years from Earth, and the images are 1.7 million, 2 million, 2.4 million and 2.2 million light-years across, respectively. By comparison our galaxy is only about 100,000 light-years across. In SPT-CLJ0307-6225 the BCG is near the bottom right of the image and in the other images they are near the centers. Some of the long, narrow features are caused by gravitational lensing, where mass in the clusters is warping the light from galaxies behind the clusters. The images have been rotated from standard astronomer’s configuration of North up by 20 degrees clockwise (SPT-CLJ0106-5943), 6.2 degrees counterclockwise (SPT-CLJ0307-6225), 29,2 degrees counterclockwise (SPT-CLJ0310-4647) and 24.2 degrees clockwise (SPT-CLJ0615-5746). The team found that the precise trigger for stars to form in the galaxies that they studied is when the amount of disordered motion in the hot gas – a physical concept called “entropy” – falls below a critical threshold. Below this threshold, the hot gas inevitably cools to form new stars. In addition to the X-ray data from Chandra X-ray Observatory and radio data from the SPT already mentioned, this result also used radio data from the Australia Telescope Compact Array, and the Australian SKA Pathfinder Telescope, infrared data from NASA’s WISE satellite, and several optical telescopes. The optical telescopes used in this study were the Magellan 6.5-m Telescopes, the Gemini South Telescope, the Blanco 4-m Telescope (DECam, MOSAIC-II) and the Swope 1m Telescope. A total of almost 50 days of Chandra observing time was used for this result. Michael Caldazilla of MIT (Massachusetts Institute of Technology) presented these results at the 243rd meeting of the American Astronomical Society in New Orleans, Louisana. In addition, there is a paper submitted to The Astrophysical Journal led by Caldazilla on this result. NASA’s Marshall Space Flight Center manages the Chandra program.

NASA/Lauren Dauphin and Wanmei Liang; NOAA The Visible Infrared Imaging Radiometer Suite sensor on the NOAA-NASA Suomi NPP satellite captured this image of the aurora borealis, or northern lights, over western Canada at 3:23 a.m. MST (5:23 a.m. EST) on November 5, 2023. Auroras are colorful ribbons of light appearing in night skies, incited by a strong geomagnetic storm in Earth’s magnetosphere. Multiple coronal mass ejections from the Sun sent a surge of charged particles toward Earth. After colliding with Earth’s magnetosphere, some particles trapped in the magnetic field are accelerated into Earth’s upper atmosphere where they excite nitrogen and oxygen molecules and release photons of light, known as the aurora. If you like watching displays such as these, you can help scientists verify aurora sightings so they can analyze and include them in space weather models.

Research engineer Christine Gregg inspects a Mobile Metamaterial Internal Co-Integrator (MMIC-I) builder robot. These simple robots are part of a hardware and software system NASA researchers are developing to autonomously build and maintain high-performance large space structures comprised of building blocks. MMIC-I works by climbing though the interior space of building blocks and bolting them to the rest of the structure during a build or unbolting during disassembly.NASA/Dominic Hart If they build it, we will go – for the long-term. Future long-duration and deep-space exploration missions to the Moon, Mars, and beyond will require a way to build large-scale infrastructure, such as solar power stations, communications towers, and habitats for crew. To sustain a long-term presence in deep space, NASA needs the capability to construct and maintain these systems in place, rather than sending large pre-assembled hardware from Earth. NASA’s Automated Reconfigurable Mission Adaptive Digital Assembly Systems (ARMADAS) team is developing a hardware and software system to meet that need. The system uses different types of inchworm-like robots that can assemble, repair, and reconfigure structural materials for a variety of large-scale hardware systems in space. The robots can do their jobs in orbit, on the lunar surface, or on other planets – even before humans arrive. Researchers at NASA’s Ames Research Center in California’s Silicon Valley recently performed a laboratory demonstration of the ARMADAS technology and analyzed the system’s performance. During the tests, three robots worked autonomously as a team to build a meters-scale shelter structure – roughly the size of a shed – using hundreds of building blocks. The team published their results today in Science Robotics. Research engineer Taiwo Olatunde, left, and intern Megan Ochalek, right, observe as robots move and assemble composite building blocks into a structure. The robots worked on their own to complete the structure in a little over 100 hours of operations. To facilitate the team’s watchful monitoring of the robots’ performance, the demonstration was split over several weeks of regular working hours. NASA/Dominic Hart “The ground assembly experiment demonstrated crucial parts of the system: the scalability and reliability of the robots, and the performance of structures they build. This type of test is key for maturing the technology for space applications,” said Christine Gregg, ARMADAS chief engineer at NASA Ames. The high strength, stiffness, and low mass of the structural product is comparable to today’s highest-performance structures, like long bridges, aircraft wings, and space structures – such as the International Space Station’s trusses. Such performance is a giant leap for the field of robotically reconfigurable structures. A Scaling Omnidirectional Lattice Locomoting Explorer (SOLL-E) builder robot carries a soccer ball-sized building block called a voxel – short for volumetric pixel – during a demonstration of NASA’s Automated Reconfigurable Mission Adaptive Digital Assembly Systems (ARMADAS) technology at NASA’s Ames Research Center in Silicon Valley. The voxels are made of strong and lightweight composite materials formed into a shape called a cuboctahedron.NASA/Dominic Hart Programmable, Reconfigurable Structures “‘Mission adaptive’ capabilities allow a system to be reused for multiple purposes, including ones that adopt hardware from completed activities, decreasing the cost of new missions,” said Kenny Cheung, ARMADAS principal investigator at NASA Ames. “‘Digital assembly systems’ refers to the use of discrete building blocks, as a physical analog to the digital systems that we use today.” Many people use digital systems to view photos or text on a display, like a smartphone screen. A digital image uses a small set of pixel types to form almost any image on a high-resolution display. You can think of pixels as building blocks for 2D space. The ARMADAS system can use a small set of 3D building blocks – called voxels, short for volumetric pixels – to form almost any structure. Just like digital images, the ARMADAS system is ‘programmable,’ meaning that it can self-reconfigure to meet evolving needs, with the help of the robots. The voxels used in the demonstration were made of strong and lightweight composite materials formed into a shape called a cuboctahedron. The voxels resemble a wire-frame soccer ball with flat faces and highly precise geometry. “It’s surprising how strong and stiff these systems are, given how they look,” said Cheung. “Making large structures from small building blocks allows us to use good materials at the lowest cost. The size of the structures that can be made is only limited by the number of building blocks that can be supplied.” This kind of scalability is revolutionary in comparison to current methods of fabricating spacecraft in factories, or even 3D printing. A Scaling Omnidirectional Lattice Locomoting Explorer (SOLL-E) builder robot carries a small building block called a voxel – short for volumetric pixel – as it maneuvers, stepping inchworm-style, along the exterior of a mechanical metamaterial structure, foreground, while a SOLL-E and a Mobile Metamaterial Internal Co-Integrator (MMIC-I) fastening robot attach a voxel to the structure, background. The highly predictable nature of the structure built by the robots allows them to build very precise structures that are much larger than themselves, unlike typical factory produced products.NASA/Dominic Hart A Reliable System Relies on Building Blocks Building blocks are also key to the robotic system autonomy and reliability. “Generally, it’s very hard to develop robust autonomous robots that can operate in unstructured environments, like a typical construction site. We turn that problem on its head by making very simple and reliable robots that operate in an extremely structured lattice environment,” said Gregg. For the demonstration, the ARMADAS team provided plans for the structure, but they didn’t micromanage the robots’ work. Software algorithms did the job of planning the robots’ tasks. The system practiced the build sequence in simulation before the actual run started. While in operation, two robots – stepping inchworm style – walked on the exterior of the structure, moving one soccer ball-sized voxel at a time. One robot fetched the voxels from a supply station and passed them to the second robot that, in turn, placed each voxel on its target location. A third robot followed these placements, climbing though the interior space of the voxels and bolting each new voxel to the rest of the structure.

Credits: NASA “Because the robots align each small step to the structure in what is essentially a 3D grid, simple algorithms with low computation and sensing requirements can achieve high-level autonomy goals. The system builds and error-corrects on its own with no machine vision or external means of measurement,” said Gregg. Future work will expand the library of voxel types that the robots work with, to include solar panels, electrical connections, shielding, and more. Each new module type will dramatically expand the possible applications because the robots can mix and match them to meet specific needs and locations. The ARMADAS team is also working on new robot capabilities, such as inspection tools, to ensure that autonomously constructed facilities are safe and sound before astronauts arrive. ARMADAS’ technology approach increases what we can do with equipment sent for most deep space exploration missions, and how long we can use them. When a mission completes, robots can disassemble space structures, repurpose the building blocks, and construct designs of the future. This concept shows a team of robots, working autonomously, constructing a solar array on the lunar surface using modular components. Because the angle of the Sun is perpetually low at future Artemis exploration destinations near the South Pole of the Moon, powering a lunar base station with sunlight requires solar panels to be arrayed vertically and high enough to avoid shadows from the lunar terrain. The robots walk on and climb through the open lattice wall structure as they build it. Also shown here is a robotically-built railway system that enables supply of modular components – in this case structural building blocks and solar panels – for the robotic job site. It also functions as conduit for electrical power and data service.NASA This artist’s concept shows landing pads being autonomously reconfigured by robots while cargo is being offloaded from a lander onto a robotically built rail system. Future lunar supply spacecraft will need landing pads with ejecta shields to avoid kicking up dust and debris that can damage space systems. Landers may serve as permanent facilities at landing sites, and infrastructure such as these shields can be repurposed. Here robots are disassembling the ejecta shield (foreground) and reassembling it in a new location (left background).NASA Artist’s concept of an autonomously optimized, assembled, and maintained lunar cave habitat and laboratory complex. Lunar caves could protect astronauts from the most difficult environmental factors governing life and work on the Moon – space radiation, micrometeoroid impacts, and extreme temperature changes. The mechanical metamaterial structures shown in this concept are constructed by simple robots using lightweight and strong building blocks. Desired performance can be achieved using building blocks made from a wide variety of materials, including ones made from lunar soil. The structures support the cave for safety and serve to isolate the facility from moonquakes, which happen often and can last for hours. The system connects to other autonomous surface activities via a robotically assembled rail system.

NASA’s Spirit and Opportunity Mars rovers landed on the Red Planet on Jan. 3 and 24, 2004, respectively. This image shows a view Opportunity captured of its own shadow on July 26 of that year, the 180th Martian day, or sol, of its mission.NASA/JPL-Caltech This month marks the 20th anniversary of Spirit and Opportunity’s landing on Mars, part of a mission whose legacy will extend far into the future. In January 2004, twin NASA rovers named Spirit and Opportunity touched down on opposite sides of Mars, kicking off a new era of interplanetary robotic exploration. They arrived in dramatic fashion three weeks apart, each nestled in a cluster of airbags that bounced along the surface around 30 times before coming to a stop and deflating. The golf cart-size rovers’ mission: to look for evidence that water once flowed on the Red Planet’s surface. Their findings would rewrite science textbooks, including Opportunity’s discovery soon after landing of the famous “blueberries” – spherical pebbles of the mineral hematite that had formed in acidic water. Several years into the mission, Spirit, undaunted but now dragging a damaged wheel, uncovered signs of ancient hot springs that could have been ideal habitats for microbial life billions of years ago (if any ever existed on the Red Planet). Scientists suspected Mars had long ago been radically different than the freezing desert it is today: Orbital images had shown what looked like networks of water-carved channels. But before Spirit and Opportunity, there was no proof that liquid water had formed those features. On the 20th anniversary of the landing of Spirit and Opportunity, celebrate NASA’s Mars Exploration Rover Project with this two-sided poster that lists some of the pioneering explorers’ accomplishments on the Red Planet.NASA/JPL-Caltech Download a free poster celebrating the 20th anniversary of the landings “Our twin rovers were the first to prove a wet, early Mars once existed,” said former project scientist Matt Golombek of NASA’s Jet Propulsion Laboratory in Southern California, which managed the Mars Exploration Rover mission. “They paved the way for learning even more about the Red Planet’s past with larger rovers like Curiosity and Perseverance.” An Enduring Legacy Thanks in part to the science collected by Spirit and Opportunity, NASA approved development of the SUV-size Curiosity rover to investigate whether the chemical ingredients that support life were present billions of years ago on what was once a watery world. (The rover found soon after its 2012 landing that they were.) Perseverance, which arrived at the Red Planet in 2021, is building on Curiosity’s success by collecting rock cores that could be brought to Earth to check for signs of ancient microbial life through the Mars Sample Return campaign, a joint effort by NASA and ESA (European Space Agency). While working on Spirit and Opportunity, engineers developed practices for exploring the surface that continue today, including the use of specialized software and 3D goggles to better navigate the Martian environment. And after honing years of expertise during the twin rovers’ travels over Mars’ rocky, sandy surface, engineers are able to plan safer, longer drives, and to quickly put together the far more complex daily plans required to operate Curiosity and Perseverance. Using footage filmed at JPL when Spirit touched down on Jan. 3, 2004, as well an animation depicting the rover’s arrival at the Red Planet, this video celebrates the 20th anniversary of Mars Exploration Rover Project landings. Spirit’s twin Opportunity arrived at Mars three weeks later. Credit: NASA/JPL-Caltech Science team members have also become more adept in their role as virtual field geologists, drawing on years of knowledge to select the best ways to investigate Martian terrain using the robotic “eyes” and tools carried by their roving partners. Martian Marathon Designed to last just 90 days, Spirit landed on Jan. 3; Opportunity, on Jan. 24. The solar-powered Mars Exploration Rovers soldiered on for years – in the case of Opportunity, nearly 15 years, before succumbing to a planet-enveloping dust storm in 2018. That durability surpassed the wildest dreams of scientists and engineers, who had only expected localized exploration over a distance of no more than one-third of a mile (600 meters). Instead, through their long-lived robotic surrogates, the team got the chance to roam a wide variety of Martian terrains. Opportunity, the first rover to go a marathon-length distance on another planet, would ultimately cover nearly 30 miles (45 kilometers) in total – the farthest distance driven on another planet. “This was a paradigm shift no one was expecting,” said former project manager John Callas of JPL. “The distance and time scale we covered were a leap in scope that is truly historic.” This artist’s concept depicts one of NASA’s Mars Exploration Rovers on the Red Planet. The twin rovers, Spirit and Opportunity, landed in 2004 and lasted years beyond their expected 90-day mission.NASA/JPL-Caltech The chance to see so much was critical for revealing that not only was Mars once a wetter world, but also that it supported many different kinds of watery environments – fresh water, hot springs, acidic and salty pools – at distinct points in its history. Continuing Inspiration The roving twins would also inspire a new generation of scientists. One of those was Abigail Fraeman, who was a high school student invited to JPL on the night of Opportunity’s landing. She got to watch the excitement as the first signal returned, confirming Opportunity had safely landed. She would go on to pursue a career as a Mars geologist, returning to JPL years later to help lead Opportunity’s science team. Now deputy project scientist for Curiosity, Fraeman calls many of the people she met on Opportunity’s landing night her close colleagues. “The people who kept our twin rovers running for all those years are an extraordinary group, and it’s remarkable how many have made exploring Mars their career,” Fraeman said. “I feel so lucky I get to work with them every day while we continue to venture into places no human has ever seen in our attempt to answer some of the biggest questions.” More About the Mission JPL, a division of Caltech in Pasadena, California, managed the Mars Exploration Rover Project for NASA’s Science Mission Directorate in Washington.

Jakobshavn Isbrae, a glacier on Greenland’s western coast, is shown in imagery taken on Sept. 5, 1985, by the Landsat 5 satellite. Jakobshavn receded from 1985 to 2022, losing about 97 billion tons (88 billion metric tons) of ice, a recent study of the Greenland Ice Sheet’s glacial retreat found.NASA/USGS A Landsat 8 image from Sept. 4, 2022, shows Jakobshavn Isbrae breaking at its edge. A recent study found that from 1985 to 2022 the Greenland Ice Sheet shed about 1,140 billion tons (1,034 billion metric tons) – one-fifth more mass than previously estimated.NASA/USGS A new, comprehensive analysis of satellite data finds that majority of glaciers on the landmass have retreated significantly. The Greenland Ice Sheet has shed about one-fifth more ice mass in the past four decades than previously estimated, researchers at NASA’s Jet Propulsion Laboratory in Southern California reported in a new paper. The majority of glaciers on the landmass have retreated significantly, and icebergs are falling into the ocean at an accelerating rate. This additional ice loss has had only an indirect impact on sea levels, but could hold implications for ocean circulation in the future. Published in Nature on Jan. 17, the analysis offers a comprehensive look at retreat around the edges of the entire ice sheet from 1985 to 2022, drawing from nearly a quarter million pieces of satellite data on glacier positions. Of the 207 glaciers in the study, 179 retreated significantly since 1985, 27 held steady, and one advanced slightly. Most of the ice loss came from below sea level, in fjords on Greenland’s periphery. Once occupied by ancient glacial ice, many of these deep coastal valleys have filled with seawater – meaning the ice that broke off made little net contribution to sea level. But the loss likely accelerated the movement of ice flowing down from higher elevations, which in turn added to sea level rise. “When the ice at the end of a glacier calves and retreats, it’s like pulling the plug out of the fjord, which lets ice drain into the ocean faster,” said Chad Greene, a glacier scientist at JPL and the study’s lead author. Accounting for Glacial Retreat For decades researchers have studied the Greenland Ice Sheet’s direct contributions to global sea level rise through ice flow and melting. Scientists participating in the international Ice sheet Mass Balance Inter-comparison Exercise (IMBIE) estimated that the ice sheet had lost 5,390 billion tons (4,890 billion metric tons) between 1992 and 2020, adding about 0.531 inches (13.5 millimeters) to global mean sea level, according to the Intergovernmental Panel on Climate Change. Imagery from the Landsat 7 satellite taken on Aug. 5, 1999, shows Zachariae Isstrom, a glacier in northeast Greenland. This glacier lost about 176 billion tons (160 billion metric tons) of ice during its retreat from 1985 to 2022, a recent study found.NASA/USGS A Landsat 8 image from Aug. 22, 2022, shows icebergs breaking from Zachariae Isstrom. From 1985 to 2022, as icebergs fell into the ocean at an accelerating rate, the Greenland Ice Sheet shed about 1,140 billion tons (1,034 billion metric tons) – one-fifth more mass than previously estimated.NASA/USGS But the IMBIE measurements do not account for ice lost due to the retreat of terminal glaciers along the edges of Greenland. (These glacier edges were already in the water, whether submerged or floating.) The new study quantifies this amount: For the 1985 to 2022 period in the new paper, the ice sheet was estimated to have lost about 1,140 billion tons (1,034 billion metric tons) – 21% more mass lost than in the IMBIE assessment. Although it doesn’t add to sea levels, the additional ice represents a significant influx of fresh water to the ocean. Recent studies have suggested that changes in the salinity of the North Atlantic Ocean from melting icebergs could weaken the Atlantic Meridional Overturning Circulation, part of the global “conveyor belt” of currents that transport heat and salt around the ocean. This could influence weather patterns worldwide, as well as affect ecosystems, the authors said. A Comprehensive View of Glacial Retreat Icebergs have tumbled from Greenland’s glaciers for thousands of years as part of a natural cycle that typically balanced glacier growth in the winter with melting and retreat in the summer. The new study finds that ice retreat has far outpaced growth throughout the 21st century. The researchers also found that Greenland’s ice extent remained relatively steady from 1985 to 2000, then started a marked recession that continues to this day. The data showed a glacier in northeast Greenland called Zachariae Isstrom lost the most ice, dropping 176 billion tons (160 billion metric tons) of mass due to retreat. It was followed by Jakobshavn Isbrae on the western coast, which lost an estimated 97 billion tons (88 billion metric tons), and Humboldt Gletscher in the northwest, which lost 96 billion tons (87 billion metric tons). Only one glacier, Qajuuttap Sermia in southern Greenland, experienced any growth over the study period, but its gains were too small to offset the losses from other glaciers. The researchers also found that glaciers with the largest seasonal fluctuations in the position of their ice front experienced the greatest overall retreat. The correlation suggests the glaciers that are most sensitive to warming each summer will be most impacted by climate change in the coming decades. The discovery of a large-scale pattern of glacier retreat and its link to glacier sensitivity on seasonal time scales was the result of a big-data synthesis that looks at all parts of the ice sheet over time, said JPL cryosphere scientist Alex Gardner, a co-author of the paper. Scientists drew from five publicly available datasets that cumulatively tracked the month-to-month positions of 236,328 glacier edges as detected, either manually or by computer algorithms, in images collected by optical and radar satellites. “Previously, we had bits and pieces – lots of local studies,” Gardner said. “But what this study offers is a systematic and comprehensive view that has led to some pretty significant insights that we didn’t have about the ice sheet before.” News Media Contacts Andrew Wang / Jane J.

Name: Michael Thorpe Title: Sedimentary and Planetary Geologist Organization: Planetary Environments Laboratory, Science Directorate (Code 699) Sedimentary and planetary geologist Dr. Michael Thorpe studies sediments’ journey from mountains to downstream lakes, both on Earth and on Mars. Photo Courtesy of Iceland Space Agency / Daniel Leeb What do you do and what is most interesting about your role here at Goddard? How do you help support Goddard’s mission? As a sedimentary and planetary geologist, my research focuses on how sediments are transformed from the mountains to the lakes downstream, which is a process called source to sink. I study this phenomenon around the globe on Earth and then compare the results to those from similar sites on Mars. Why did you become a geologist? I grew up on the Hudson River Valley and loved to be outdoors. I knew that I wanted to pursue a career that kept me outdoors hiking, looking at nature and the environment. My sister, my hiking companion, always told me that rocks have a story to tell, which inspired me. What is your educational background? I have a bachelor’s degree in geology from Towson University, and both a master’s and a doctorate in geosciences from Stony Brook University. I then did a NASA post-doctoral fellowship at NASA’s Johnson Space Center in Houston. I was also later contracted at Johnson as a Mars Sample Return scientist. Why did you come to Goddard? Goddard was a dream job for me because I have always admired the group of scientists here, and I really wanted to work with the team in the planetary environments laboratory. Over the years, I closely followed their work, and it is exciting to be in a role to start contributing. I came to Goddard in July 2022 and tried to hit the ground running. Dr. Michael Thorpe, a sedimentary and planetary geologist at Goddard, travels around the world on field campaigns to collect sediment samples. “I hope to keep exploring places around the globe because each field site adds a new piece to the puzzle,” he said. “However, every place I go, the puzzle ends up getting more complex and it motivates me to develop more questions for the next adventure.”Photo Courtesy of Iceland Space Agency / Daniel Leeb Tell us about your field campaigns. I target terrains on Earth that may have been similar to ancient environments on the surface of Mars. To add some complexity to the system, I explore environments around the globe to better understand the impact climate has on the weathering of rocks. This work has implications for planetary exploration but also helps in understanding the long-term carbon cycle on Earth and its role in climate change. In the field, I scoop up sediments, rocks, and water samples all the way from the source terrains in the mountains to depositional sites downstream. I then bring them back to our labs here at Goddard to study their geochemistry and minerology, but also ship samples off to my amazing collaborators for additional analysis in their labs around the world. I have been super lucky early in my career be a part of five field campaigns to Iceland and then one to Hawaii, Idaho, and most recently Lazarote, Spain. I hope to keep exploring places around the globe because each field site adds a new piece to the puzzle. However, every place I go, the puzzle ends up getting more complex and it motivates me to develop more questions for the next adventure. What preparations do you take to conduct remote field work? I’ll use Iceland as example for this one. For this work, we commonly are trekking to remote locations. In order to get there, we took modified trucks which were able to go through water, ice, and snow and even climb some pretty steep terrains. Theses trucks are cool because the driver can inflate and deflate the very large tires in real-time. In the field, we wear our warm gear including down jackets but also sometimes waders to keep us dry while surveying a river. One of my favorite pieces of clothing in the field is a buff, which sits around our necks but we can also pull it up over our faces to shield us from the elements, which can include 70-plus mph winds at times. Some recent and exciting preparation we have for the field is bringing an inflatable boat, basically a floating pontoon, to sample lake sediment. We take the pontoon over the water and then drill for sediment samples off the platform. How important is a good team during remote field work? Establishing a good team is the foundation for successful field work. As a team leader, it is important to recognize the strengths as well as the limitations of all personnel, including myself. I am aware of my specialties and the areas where each teammate may thrive. When you put the right person in the right position, it makes the team excel. This fosters mutual respect and builds a support system. We understand we need to get the job done and how important each role is for the entire team. I tend go out in fairly large groups, sometimes as many as 25 people. We all respect the science and each other. Everyone brings a different piece to the team. When we are sampling, everyone has a mission and a role, sometimes creating sub-teams to a sample different area or components of the study site. Dr. Michael Thorpe, a sedimentary and planetary geologist at Goddard, is regularly taken to harsh environments in his study of sediments around the globe.Photo Courtesy of Iceland Space Agency / Daniel Leeb What is the most important advice your mentor Amy McAdam told you? Amy is the geochemist who leads our lab. Amy’s most important advice for me has been “go for it.” I say that jokingly, but it truly is incredibly helpful as a scientist to have someone backing you like that. She puts me in a position to succeed and always gives me the thumbs up to follow my scientific curiosity. Amy leads by example, both in the lab and field, I am grateful for all her support and look forward to working with her for many years. As a mentor yourself, what is the one thing you tell your students? Stay curious and do what you love. That’s the motto I have been following in my career, passed down from an amazing lineage of mentors, and I encourage all my mentees to do the same. It’s important for my students to follow their passions as well as to come up with new ideas. At the end of the day, it is remarkable to see a student develop their own research avenue. I hope to continue paying it forward and I look forward to mentoring the next generation of scientists for years to come. What do you do for fun? I love to watch and play all sports. Additionally, hiking brings me to my happy place. Hitting the trails with friends or my pup is icing on the cake. Speaking of cake, I also thoroughly enjoy cooking. Cooking relaxes me, it brings the family together, and it’s also something my wife and I love to do together. One of our favorite traditions is pizza Fridays, where we make some homemade pies and everyone is welcome. As for toppings, my favorite might be fried eggplant or spicy Italian sausage. If you were to have a dinner party, who would you invite, living or dead, in addition to your family? Easy! I’ve actually thought about this a ton. I would of course first invite my favorite athletes: Michael Jordan, Kobe Bryant, Derek Jeter, and Emmitt Smith. These guys were my role models growing up and their work ethic was truly inspiring. Additionally, I would love to sit down and have a pizza pie with Neil Armstrong and Jack Schmitt. Neil was obviously the first man on the Moon and Jack was the first geologist on the Moon. Hearing some stories from these pioneers would no-doubt be a lifetime highlight. What is your “six-word memoir”? A six-word memoir describes something in just six words. Motivated. Passionate.

Sometimes, stars can be stripped away from globular clusters as they orbit a massive galaxy. Researchers have identified several instances in our own Milky Way galaxy – and they’ve also spotted gaps between these looping tendrils. What caused those gaps? One possibility: a substance known as dark matter. Following the launch of the Nancy Grace Roman Space Telescope, astronomers will use its vast, high-definition images to spot many more tidal streams – and potentially their accompanying gaps – in nearby galaxies for the first time. A prime candidate is our neighbor, the Andromeda galaxy, which appears in the illustration above. Soon, not only will researchers be able to identify tidal streams in Andromeda, they may also be able to use Roman’s fine resolution to pinpoint more properties of this mysterious substance.Credit: NASA, Joseph Olmsted (STScI) Some of the finest, smallest details in the universe – the gaps between elongated groups of stars – may soon help astronomers reveal dark matter in greater detail than ever before. After NASA’s Nancy Grace Roman Space Telescope launches, by May 2027, researchers will use its images to explore what exists between looping tendrils of stars that are pulled from globular clusters. Specifically, they will focus on the tidal streams from globular clusters that orbit our neighboring Andromeda galaxy. Their aim is to pinpoint a greater number of examples of these tidal streams, examine gaps between the stars, and ideally determine concrete properties of dark matter. Globular cluster streams are like ribbons fluttering in the cosmos, both leading and trailing the globular clusters where they originated along their orbits. Their lengths in our Milky Way galaxy vary wildly. Very short stellar streams are relatively young, while those that completely wrap around a galaxy may be almost as old as the universe. A stream that is fully wrapped around the Andromeda galaxy could be more than 300,000 light-years long but less than 3,000 light-years wide. With Roman, astronomers will be able to search nearby galaxies for globular cluster stellar streams for the first time. Roman’s Wide Field Instrument has 18 detectors that will produce images 200 times the size of the Hubble Space Telescope’s near-infrared camera – at a slightly greater resolution. “Roman will be able to take a huge snapshot of the Andromeda galaxy, which simply isn’t possible with any other telescope,” shared Christian Aganze, the lead author of a recent paper about this subject and a postdoc at Stanford University in California. “We also project that Roman will be able to detect stars individually.” Imagine the results: Roman’s vast, exquisitely detailed images will allow researchers to easily identify many examples of globular cluster streams in Andromeda. To date, astronomers using existing telescopes in space and on the ground have been limited to studying a slightly smaller number of globular cluster streams within our Milky Way. The vast footprint of the upcoming Nancy Grace Roman Space Telescope’s Wide Field Instrument shows how much its camera could observe in a single image. (The Wide Field Instrument has 18 square detectors.) Within this footprint is a simulated Roman image. The background is a ground-based image of the main disk of the Andromeda galaxy from the Digitized Sky Survey. A photo of the full Moon from NASA’s Lunar Reconnaissance Orbiter is provided for scale. Andromeda has a diameter of about 3 degrees on the sky, while the Moon is about 0.5 degrees across. (In reality, the Moon is much smaller than Andromeda, but it is also a lot closer.) The Wide Field Instrument’s footprint captures 0.28 square degrees of the sky in a single shot. Andromeda is a spiral galaxy that is similar in size and structure to our Milky Way galaxy, but is more massive. It is located approximately 2.5 million light-years from Earth.Credit: Image: NASA, NASA-GSFC, ASU, Robert Gendler DSS; Simulation: NASA, STScI, Benjamin F. Williams (UWashington) Is Dark Matter Between the Stars? Dark matter, which many assume to be a particle, can’t yet be observed directly, because it doesn’t emit, reflect, refract, or absorb light. If we can’t see it, how do we know it’s there? “We see dark matter’s effect on galaxies,” Aganze clarified. “For example, when we model how galaxies rotate, we need extra mass to explain their rotation. Dark matter may provide that missing mass.” All galaxies, including the Milky Way, are surrounded by a dark matter halo. As astronomers glean more about the nature of dark matter, they may find evidence that a galaxy’s halo may also contain a large number of smaller dark matter sub-halos, which are predicted by models. “These halos are probably roughly spherical, but their density, sizes, and even if they exist isn’t currently known,” explained Tjitske Starkenburg, a co-author and a research assistant professor at Northwestern University in Evanston, Illinois. Roman will redefine their search. “We expect dark matter to interact with globular cluster streams. If these sub-halos are present in other galaxies, we predict that we will see gaps in globular cluster streams that are likely caused by dark matter,” Starkenburg continued. “This will give us new information about dark matter, including which kinds of dark matter halos are present and what their masses are.” Aganze and Starkenburg estimate that Roman will efficiently deliver the data they need within nearby galaxies – requiring only a total of one hour – and that these observations may be captured by the High Latitude Wide Area Survey. Starkenburg will also help lay the groundwork for this investigation through her contributions to another project recently selected for funding by NASA’s Nancy Grace Roman Space Telescope Research and Support Participation Opportunities program. “­This team plans to model how globular clusters form into stellar streams by developing a much more detailed theoretical framework,” she explained. “We’ll go on to predict where globular clusters that form streams originated and whether these streams will be observable with Roman.” Aganze is also excited about other projects currently or soon coming online. “The European Space Agency’s Euclid mission is already starting to explore the large-scale structure of the universe, which will help us learn more about the role of dark matter,” he said. “And the Vera C. Rubin Observatory will soon scan the night sky repeatedly with similar goals. The data from these missions will be incredibly useful in constraining our simulations while we prepare for Roman.” The Nancy Grace Roman Space Telescope is managed at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, with participation by NASA’s Jet Propulsion Laboratory and Caltech/IPAC in Southern California, the Space Telescope Science Institute in Baltimore, and a science team comprising scientists from various research institutions. The primary industrial partners are Ball Aerospace and Technologies Corporation in Boulder, Colorado; L3Harris Technologies in Melbourne, Florida; and Teledyne Scientific & Imaging in Thousand Oaks, California.

5 Min Read Webb Shows Many Early Galaxies Looked Like Pool Noodles, Surfboards Researchers are analyzing distant galaxies when the universe was only 600 million to 6 billion years old. Credits: NASA, ESA, CSA, Steve Finkelstein (UT Austin), Micaela Bagley (UT Austin), Rebecca Larson (UT Austin) Researchers analyzing images from NASA’s James Webb Space Telescope have found that galaxies in the early universe are often flat and elongated, like surfboards and pool noodles – and are rarely round, like volleyballs or frisbees. “Roughly 50 to 80% of the galaxies we studied appear to be flattened in two dimensions,” explained lead author Viraj Pandya, a NASA Hubble Fellow at Columbia University in New York. “Galaxies that look like pool noodles or surfboards seem to be very common in the early universe, which is surprising, since they are uncommon nearby.” The team focused on a vast field of near-infrared images delivered by Webb, known as the Cosmic Evolution Early Release Science (CEERS) Survey, plucking out galaxies that are estimated to exist when the universe was 600 million to 6 billion years old. Image: Sample Shapes of Distant Galaxies Researchers analyzing distant galaxies that show up in the Cosmic Evolution Early Release Science (CEERS) Survey from NASA’s James Webb Space Telescope found an array of odd shapes when the universe was only 600 million to 6 billion years old. The inset at the top left shows a galaxy that looks more like a sphere, and is the least common in Webb’s results, along with an example of a galaxy that appears as an edge-on disk but may be better classified as elongated. Elongated shapes are one of the most common identified so far in Webb’s survey.NASA, ESA, CSA, Steve Finkelstein (UT Austin), Micaela Bagley (UT Austin), Rebecca Larson (UT Austin) While most distant galaxies look like surfboards and pool noodles, others are shaped like frisbees and volleyballs. The “volleyballs,” or sphere-shaped galaxies, appear the most compact type on the cosmic “ocean” and were also the least frequently identified. The frisbees were found to be as large as the surfboard- and pool noodle-shaped galaxies along the “horizon,” but become more common closer to “shore” in the nearby universe. (Compare them in this illustration.) Which category would our Milky Way galaxy fall into if we were able to wind the clock back by billions of years? “Our best guess is that it might have appeared more like a surfboard,” said co-author Haowen Zhang, a PhD candidate at the University of Arizona in Tucson. This hypothesis is based partly on new evidence from Webb – theorists have “wound back the clock” to estimate the Milky Way’s mass billions of years ago, which correlates with shape at that time. Image: 3D Classifications for Distant Galaxies These are examples of distant galaxies captured by NASA’s James Webb Space Telescope in its CEERS Survey. Galaxies frequently appear flat and elongated, like pool noodles or surfboards (along the top row). Thin, circular disk-like galaxies, which resemble frisbees, are the next major grouping (shown at lower left and center). Galaxies that are shaped like spheres, or volleyballs, made up the smallest fraction of their detections (shown at lower right). All of these galaxies are estimated to have existed when the universe was only 600 million to 6 billion years old.NASA, ESA, CSA, Steve Finkelstein (UT Austin), Micaela Bagley (UT Austin), Rebecca Larson (UT Austin) These distant galaxies are also far less massive than nearby spirals and ellipticals – they are precursors to more massive galaxies like our own. “In the early universe, galaxies had had far less time to grow,” said Kartheik Iyer, a co-author and NASA Hubble Fellow also at Columbia University. “Identifying additional categories for early galaxies is exciting – there’s a lot more to analyze now. We can now study how galaxies’ shapes relate to how they look and better project how they formed in much more detail.” Webb’s sensitivity, high-resolution images, and specialization in infrared light allowed the team to make quick work of characterizing many CEERS galaxies, and model their 3D geometries. Pandya also says their work wouldn’t be possible without the extensive research astronomers have done using NASA’s Hubble Space Telescope. For decades, Hubble has wowed us with images of some of the earliest galaxies, beginning with its first “deep field” in 1995 and continuing with a seminal survey known as Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey. Deep sky surveys like these led to far greater statistics, leading astronomers to create robust 3D models of distant galaxies over all of cosmic time. Today, Webb is helping to enhance these efforts, adding a bounty of distant galaxies beyond Hubble’s reach and revealing the early universe in far greater detail than previously possible. Webb’s images of the early universe have acted like an ocean swell – delivering new waves of evidence. “Hubble has long showed an excess of elongated galaxies,” explained co-author Marc Huertas-Company, a faculty research scientist at the Institute of Astrophysics on the Canary Islands. But researchers still wondered: Would additional detail show up better with sensitivity to infrared light? “Webb confirmed that Hubble didn’t miss any additional features in the galaxies they both observed. Plus, Webb showed us many more distant galaxies with similar shapes, all in great detail.” There are still gaps in our knowledge – researchers not only need an even larger sample size from Webb to further refine the properties and precise locations of distant galaxies, they will also need to spend ample time tweaking and updating their models to better reflect the precise geometries of distant galaxies. “These are early results,” said co-author Elizabeth McGrath, an associate professor at Colby College in Waterville, Maine. “We need to delve more deeply into the data to figure out what’s going on, but we’re very excited about these early trends.” The James Webb Space Telescope is the world’s premier space science observatory. Webb is solving mysteries in our solar system, looking beyond to distant worlds around other stars, and probing the mysterious structures and origins of our universe and our place in it. Webb is an international program led by NASA with its partners, ESA (European Space Agency) and the Canadian Space Agency.

NASA and Lockheed Martin publicly unveil the X-59 quiet supersonic research aircraft at a ceremony in Lockheed Martin’s Skunk Works facility in Palmdale, California. The X-59 is the centerpiece of NASA’s Quesst mission, which seeks to solve one of the major barriers to supersonic flight over land, currently banned in the United States, by making sonic booms quieter.NASA/Steve Freeman A climactic curtain drop reveals the newly painted red, white, and blue X-59 aircraft during its rollout ceremony on Jan. 12, 2024, at Lockheed Martin Skunk Works in Palmdale, California – a major milestone before its first flight. A long-standing aviation tradition, rollout ceremonies celebrate years of technical achievements. In the case of the X-59, not only does it celebrate groundbreaking technical work, but it honors the brilliant minds behind the research, development, and construction that went into a one-of-a-kind supersonic research aircraft. The X-59 is a research tool in NASA’s Quesst mission designed to prove quiet supersonic flight is possible. Through Quesst, NASA will fly the aircraft over select U.S. communities, working with them to collect data. NASA will provide that data to regulators so they may consider writing new sound-based rules that would amend the current ban on commercial supersonic flight over land. Next up, the X-59 team will conduct a series of integrated ground tests, including engine runs and taxi tests, to prepare for the aircraft’s first flight.

Science Launching to Space Station on NASA's 20th Northrop Grumman Mission

6 Min Read Science Launches to Space Station on NASA’s 20th Northrop Grumman Mission iss067e156135 (July 28, 2022) — Northrop Grumman's Cygnus space freighter is positioned away from the International Space Station in the grips of the Canadarm2 robotic arm prior to its release ending a four-month stay attached to the orbiting lab's Unity module. Credits: NASA Tests of a 3D metal printer, semiconductor manufacturing, and thermal protection systems for reentry to Earth’s atmosphere are among the scientific investigation that NASA and international partners are launching to the International Space Station on Northrop Grumman’s 20th commercial resupply services mission. The company’s Cygnus cargo spacecraft is scheduled to launch on a SpaceX Falcon 9 rocket from Cape Canaveral Space Force Station in Florida by late January. Read more about some of the research making the journey to the orbiting laboratory: 3D Printing in Space An investigation from ESA (European Space Agency), Metal 3D Printer tests additive manufacturing or 3D printing of small metal parts in microgravity. “This investigation provides us with an initial understanding of how such a printer behaves in space,” said Rob Postema of ESA. “A 3D printer can create many shapes, and we plan to print specimens, first to understand how printing in space may differ from printing on Earth and second to see what types of shapes we can print with this technology. In addition, this activity helps show how crew members can work safely and efficiently with printing metal parts in space.” Results could improve understanding of the functionality, performance, and operations of metal 3D printing in space, as well as the quality, strength, and characteristics of the printed parts. Resupply presents a challenge for future long-duration human missions. Crew members could use 3D printing to create parts for maintenance of equipment on future long-duration spaceflight and on the Moon or Mars, reducing the need to pack spare parts or to predict every tool or object that might be needed, saving time and money at launch. Advances in metal 3D printing technology also could benefit potential applications on Earth, including manufacturing engines for the automotive, aeronautical, and maritime industries and creating shelters after natural disasters. A team led by Airbus U.S. Space & Defense and Space SAS under a contract with ESA developed the investigation. Samples produced by the Metal 3D Printer prior to launch to the space station. ESA Semiconductor Manufacturing in Microgravity Manufacturing of Semiconductors and Thin-Film Integrated Coatings (MSTIC) examines how microgravity affects thin films that have a wide range of uses. “The potential for producing films with superior surface structures and the broad range of applications from energy harvesting to advanced sensor technology are particularly groundbreaking,” said Alex Hayes of Redwire Space, which developed the technology. “This represents a significant leap in space manufacturing and could herald a new era of technological advancements with wide-reaching implications for both space exploration and terrestrial applications.” This technology could enable autonomous manufacturing to replace the many machines and processes currently used to make a wide range of semiconductors, potentially leading to the development of more efficient and higher-performing electrical devices. Manufacturing semiconductor devices in microgravity also may improve their quality and reduce the materials, equipment, and labor required. On future long-duration missions, this technology could provide the capability to produce components and devices in space, reducing the need for resupply missions from Earth. The technology also has applications for devices that harvest energy and provide power on Earth. “While this initial pilot program is designed to compare thin films produced on Earth and in space, the ultimate goal is to expand to producing a diverse range of production areas within the semiconductor field,” Hayes said. The gas supply modules and production module for Redwire’s MSTIC investigation. Redwire Modeling Atmospheric Re-entry Scientists who conduct research on the space station often return their experiments to Earth for additional analysis and study. But the conditions that spacecraft experience during atmospheric reentry, including extreme heat, can have unintended effects on their contents. Thermal protection systems used to shield spacecraft and their contents are based on numerical models that often lack validation from actual flight, which can lead to significant overestimates in the size of system needed and take up valuable space and mass. Kentucky Re-entry Probe Experiment-2 (KREPE-2), part of an effort to improve thermal protection system technology, uses three capsules outfitted with different heat shield materials and a variety of sensors to obtain data on actual reentry conditions. “Building on the success of KREPE-1, we have improved the sensors to gather more measurements and improved the communication system to transmit more data,” said principal investigator Alexandre Martin at the University of Kentucky. “We have the opportunity to test several heat shields provided by NASA that have never been tested before, and another manufactured entirely at the University of Kentucky, also a first.” The capsules can be outfitted for other atmospheric re-entry experiments, supporting improvements in heat shielding for applications on Earth, such as protecting people and structures from wildfires.

Adams, University of Kentucky Remote Robotic Surgery Robotic Surgery Tech Demo tests the performance of a small robot that can be remotely controlled from Earth to perform surgical procedures. Researchers plan to compare procedures in microgravity and on Earth to evaluate the effects of microgravity and time delays between space and ground. The robot uses two “hands” to grasp and cut simulated surgical tissue and provide tension that is used to determine where and how to cut, according to Shane Farritor, chief technology officer at Virtual Incision Corporation, developer of the investigation with the University of Nebraska. Longer space missions increase the likelihood that crew members may need surgical procedures, whether simple stiches or an emergency appendectomy. Results from this investigation could support development of robotic systems to perform these procedures. In addition, the availability of a surgeon in rural areas of the country declined nearly a third between 2001 and 2019. Miniaturization and the ability to remotely control the robot may help to make surgery available anywhere and anytime. NASA has sponsored research on miniature robots for more than 15 years. In 2006, remotely operated robots performed procedures in the underwater NASA’s Extreme Environment Mission Operations (NEEMO) 9 mission. In 2014, a miniature surgical robot performed simulated surgical tasks on the Zero-G parabolic airplane. The surgical robot during testing on the ground before launch. Virtual Incision Corporation Growing Cartilage Tissue in Space Compartment Cartilage Tissue Construct demonstrates two technologies, Janus Base Nano-Matrix (JBNm) and Janus Base Nanopiece (JBNp). JBNm is an injectable material that provides a scaffold for formation of cartilage in microgravity, which can serve as a model for studying cartilage diseases. JBNp delivers an RNA-based therapy to combat diseases that cause cartilage degeneration. Cartilage has a limited ability to self-repair and osteoarthritis is a leading cause of disability in older patients on Earth. Microgravity can trigger cartilage degeneration that mimics the progression of aging-related osteoarthritis but happens more quickly, so research in microgravity could lead to faster development of effective therapies. Results from this investigation could advance cartilage regeneration as a treatment for joint damage and diseases on Earth and contribute to development of ways to maintain cartilage health on future missions to the Moon and Mars. The Janus Base Nano-matrix anchors cartilage cells (red) and facilitates the formation of the cartilage tissue matrix (green).

Radio emissions from the remnant are blue-green, whereas X-rays combined from IXPE, XMM-Newton, and Chandra are highlighted in bright blue-purple and pinkish-white against a backdrop of infrared data in red. The black hole emits twin jets of matter traveling in opposite directions at nearly the speed of light, distorting the remnant’s shape. The jets become bright about 100 light years away from the black hole, where particles are accelerated to very high energies by shocks within the jet. The IXPE data shows that the magnetic field, which plays a key role in how particles are accelerated, is aligned parallel to the jet – aiding our understanding of how astrophysical jets accelerate these particles to high energies.X-ray: (IXPE): NASA/MSFC/IXPE; (Chandra): NASA/CXC/SAO; (XMM): ESA/XMM-Newton; IR: NASA/JPL/Caltech/WISE; Radio: NRAO/AUI/NSF/VLA/B.

Saxton. (IR/Radio image created with data from M. Goss, et al.); Image Processing: NASA/CXC/SAO/N. Wolk & K.Arcand The powerful gravity fields of black holes can devour whole planets’ worth of matter – often so violently that they expel streams of particles traveling near the speed of light in formations known as jets. Scientists understand that these high-speed jets can accelerate these particles, called cosmic rays, but little is definitively known about that process. Recent findings by researchers using data from NASA’s IXPE (Imaging X-ray Polarimetry Explorer) spacecraft give scientists new clues as to how particle acceleration happens in this extreme environment. The observations came from a “microquasar,” a system comprised of a black hole siphoning off material from a companion star. The microquasar in question – Stephenson and Sanduleak 433, or SS 433 – sits in the center of the supernova remnant W50 in the constellation Aquila, some 18,000 light-years from Earth. SS 433’s powerful jets, which distort the remnant’s shape and earned it the nickname the “Manatee Nebula,” have been clocked at roughly 26% of the speed of light, or more than 48,000 miles per second. Identified in the late 1970s, SS 433 is the first microquasar ever discovered. IXPE’s three onboard telescopes measure a special property of X-ray light called polarization, which tells scientists about the organization and alignment of electromagnetic waves at X-ray frequencies. X-ray polarization helps researchers understand the physical processes taking place within extreme regions of our universe such as the environment around black holes, and how particles get accelerated in these regions. IXPE spent 18 days in April and May of 2023 studying one such acceleration site in the eastern lobe of SS 433, where emissions are made by energetic electrons spiraling in a magnetic field – a process called synchrotron radiation. “The IXPE data show that the magnetic field near the acceleration region points in the direction the jets are moving,” said astrophysicist Philip Kaaret of NASA’s Marshall Space Flight Center in Huntsville, Alabama, and principal investigator of the IXPE mission, along with lead author of a new paper about the findings at SS 433. “The high level of polarization seen with IXPE shows that the magnetic field is well ordered, with at least half of the field aligned in the same direction,” Kaaret said. That finding was unexpected, he said. Researchers have long theorized that the interaction between the jet and the interstellar medium – the environment of gas and dust between stars — likely creates a shock, leading to disordered magnetic fields. The data suggests a new possibility, Kaaret said – that the magnetic fields within the powerful jets may be “trapped” and stretched when they collide with interstellar matter, directly impacting their alignment in the region of particle acceleration. Since the 1980s, researchers have surmised that SS 433’s jets act as particle accelerators. In 2018, observers at the High-Altitude Water Cherenkov Observatory in Puebla, Mexico, verified the jets’ acceleration effect, and scientists used NASA’s NuSTAR (Nuclear Spectroscopic Telescope Array) and the European Space Agency’s XMM-Newton observatories to pinpoint the region of acceleration. As researchers continue to assess IXPE findings and study new targets in space, its data also could help determine whether the same mechanism acts to align magnetic fields in outflows expelled by a variety of phenomena – from black hole jets streaming away from supernova remnants to debris ejected from exploded stars such as blazars. “This very delicate measurement was made possible by the imaging capabilities of IXPE’s X-ray polarimeters, making possible the detection of the tenuous signal in a small region of the jet 95 light-years from the central black hole,” said Paolo Soffitta, Italian principal investigator for the IXPE mission. The new paper, detailing IXPE’s observations at SS 433, is available in the latest edition of The Astrophysical Journal.

As the Space Food Systems manager at NASA’s Johnson Space Center in Houston, Xulei Wu works with a team to create tasty, shelf-stable meals for astronauts aboard the International Space Station and, soon, for crews flying to the Moon as part of the Artemis program. What does it take to become a space food scientist at NASA? We met up with Wu to learn more about her journey from creating meals for camping in the deep woods, to making foods for exploring deep space. Preparation Meets Opportunity “I don’t consider myself very smart; I’m very hardworking,” said Wu, who was born and raised in China and is a first-generation immigrant. After rising through the ranks at a major U.S. freeze-dried food company, Wu was content in her job creating shelf-stable foods for people to rely on when the tools and conveniences of a modern kitchen aren’t available. Her work kept her busy – too busy to consider other careers or applications for her unique skillset. It took a flat tire to literally stop her in her tracks long enough to spot a job opening that sparked a new direction for her career. “I got a nail in my tire, so I broke down on the highway,” Wu said. While she was waiting for roadside assistance, she began to scroll through her phone. That’s when, she said, “I found out a freeze-dried food scientist position was opening at the NASA Space Food Systems Laboratory.” Even though Wu enjoyed working in the food industry, she said it was NASA’s larger mission that inspired her to apply. “My favorite part of this job is really to serve a large purpose, that I’m part of the effort to support human space exploration, so that one day we can go back to the Moon,” Wu said. Choosing From a Menu of Sciences “My education and my experience definitely prepared me to land a job in the Space Food System Laboratory, and I consider myself extremely lucky,” Wu said. Growing up, Wu enjoyed science so much that when she had to choose a college major, she had a hard time narrowing her choices between biology, chemistry, and physics. As she considered her options, reports of babies being sickened by infant formula gained national attention in China. Several formula companies were found to have deliberately contaminated their products with a chemical that gave the appearance of higher protein content but resulted in kidney problems for thousands of babies. The scandal piqued her interest in food safety. “That was the trigger,” Wu said. “I realized: I want to study more about food safety. And food science happened to involve multiple different disciplines in that process.” Wu earned a bachelor’s degree in food science and engineering from Shanghai Jiao Tong University, then a master’s degree in food science and technology from Oregon State University. After graduation, she went to work for North America’s largest supplier of freeze-dried foods where she created food products targeted for outdoor recreation, like camping, and also for emergency preparedness. In this role, she worked on similar challenges to those she works on today: how to keep food fresh, tasty, nutritious, and shelf-stable for long periods of time. “All of those are needed perspectives [for] working in the Space Food Systems Laboratory,” Wu said. “For the International Space Station, we’re targeting three years’ shelf life; for a Mars mission, we’re talking five to seven years’ shelf life.” Advice to Future Food Scientists Wu shared some advice to students: focus on what you really care about, work hard, and be ready to take your own giant leap. “It’s important to discover your true interest, your true passion, the subject you love the most, and then connect this to a career making a contribution to society.” But as with Wu’s experience, sometimes you get a nail in your tire on the path to your next big break. It’s what you do in those moments that can define you. “Don’t doubt yourself,” Wu said. “it's okay to have a difficult time. Give it a try. Give it a shot. Because as long as you work hard enough, you will find out what you're truly fit for.” Xulei Wu Space Food Systems Manager Lean more about Xulei Wu and her job at NASA in this episode of Surprisingly STEM.
