‘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.

National Mentor Month: Navigating Mentorship with Michoud’s Cynthia Spraul and Marie Allain

By Celine Smith

As a mentor at NASA’s MAF (Michoud Assembly Facility), Cynthia Spraul says her goal is the success of her mentee, Marie Allain.

“It feels really good to pass on my experience to somebody who can get there faster and go beyond,” Spraul said.

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. Marshall team members can learn more about the benefits of mentoring on Inside Marshall.

NASA Shares Progress Toward Early Artemis Moon Missions with Crew

NASA announced Jan. 9 updates to its Artemis campaign that will establish the foundation for long-term scientific exploration at the Moon, land the first woman and first person of color on the lunar surface, and prepare for human expeditions to Mars for the benefit of all. 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.

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.

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.

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.

NASA Shares Lessons Learned in Low Earth Orbit Through Payload Workshop

By Jessica Barnett

NASA welcomed commercial partners from around the globe to Marshall Space Flight Center for a three-day workshop last fall, highlighting what the agency has learned during its more than 20 years in Low Earth orbit.

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.

“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.

“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.

Brr, It’s Cold in Here! 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).

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.

Astronomers Find Spark of Star Birth Across Billions of Years

Four images from NASA’s Chandra X-ray Observatory and other telescopes 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, as described in a press release.

This research showed that the conditions for stellar conception in these exceptionally massive galaxies have not changed over the last ten billion years.

This release includes composite images of four galaxy clusters, presented in a two-by-two grid. Each image features a hazy, purple cloud representing X-rays from hot gas observed by Chandra. The distant galaxies in and around the clouds of hot gas have been captured in optical data, and are shown in golden yellows with hints of vibrant cyan blue.
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.

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 and Partners Scaling to New Heights in Air Traffic Management
      by Hillary Smith
      NASA, in partnership with AeroVironment and Aerostar, recently demonstrated a first-of-its-kind air traffic management concept that could pave the way for aircraft to safely operate at higher altitudes.
      This work seeks to open the door for increased internet coverage, improved disaster response, expanded scientific missions, and even supersonic flight. The concept is referred to as an Upper-Class E traffic management, or ETM.  There is currently no traffic management system or set of regulations in place for aircraft operating 60,000 feet and above. There hasn’t been a need for a robust traffic management system in this airspace until recently. That’s because commercial aircraft couldn’t function at such high altitudes due to engine constraints.  
      NASA and partners from Aerostar and AeroVironment discuss a simulation of a high-altitude air traffic management system in the Airspace Operations Lab at NASA Ames.NASA photo by Don Richey However, recent advancements in aircraft design, power, and propulsion systems are making it possible for high- altitude, long-endurance vehicles — such as balloons, airships, and solar aircraft — to coast miles above our heads, providing radio relay for disaster response, collecting atmospheric data, and more.  
      But before these aircraft can regularly take to the skies, operators must find a way to manage their operations without overburdening air traffic infrastructure and personnel.  
      “We are working to safely expand high-altitude missions far beyond what is currently possible,” said Kenneth Freeman, a subproject manager for this effort at NASA’s Ames Research Center in California’s Silicon Valley. “With routine, remotely piloted high-altitude operations, we have the opportunity to improve our understanding of the planet through more detailed tracking of climate change, provide internet coverage in underserved areas, advance supersonic flight research, and more.” 
      Current high-altitude traffic management is processed manually and on a case-by-case basis. Operators must contact air traffic control to gain access to a portion of the Class E airspace. During these operations, no other aircraft can enter this high-altitude airspace. This method will not accommodate the growing demand for high-altitude missions, according to NASA researchers.  
      To address this challenge, NASA and its partners have developed an ETM traffic management system that allows aircraft to autonomously share location and flight plans, enabling aircraft to stay safely separated. 
      During the recent traffic management simulation in the Airspace Operations Laboratory at Ames, data from multiple air vehicles was displayed across dozens of traffic control monitors and shared with partner computers off site.
      This included aircraft location, health, flight plans and more. Researchers studied interactions between a slow fixed-wing vehicle from AeroVironment and a high-altitude balloon from Aerostar operating at stratospheric heights.
      Each aircraft, connected to the ETM traffic management system for high altitude, shared location and flight plans with surrounding aircraft.  
      This digital information sharing allowed Aerostar and AeroVironment high-altitude vehicle operators to coordinate and deconflict with each other in the same simulated airspace, without having to gain approval from air traffic control.
      Because of this, aircraft operators were able to achieve their objectives, including wireless communication relay. 
      This simulation represents the first time a traffic management system was able to safely manage a diverse set of high-altitude aircraft operations in the same simulated airspace.
      Next, NASA researchers will work with partners to further validate this system through a variety of real flight tests with high-altitude aircraft in a shared airspace.   
      The Upper-Class E traffic management concept was developed in coordination with the Federal Aviation Administration and high-altitude platform industry partners, under NASA’s National Airspace System Exploratory Concepts and Technologies subproject led out of Ames.  

      Starship Super Heavy Breezes Through Wind Tunnel Testing at NASA Ames
      by Lee Mohon
      NASA and its industry partners continue to make progress toward Artemis III and beyond, the first crewed lunar landing missions under the agency’s Artemis campaign. SpaceX, the commercial Human Landing System (HLS) provider for Artemis III and Artemis IV, recently tested a 1.2% scale model of the Super Heavy rocket, or booster, in the transonic Unitary Plan Wind Tunnel at NASA Ames. The Super Heavy rocket will launch the Starship human landing system to the Moon as part of Artemis.
      A 1.2% scale model of the Super Heavy rocket that will launch the Starship human landing system to the Moon for future crewed Artemis missions was recently tested at NASA Ames’ transonic wind tunnel, providing valuable information on vehicle stability when re-entering Earth’s atmosphere.NASA During the tests, the wind tunnel forced an air stream at the Super Heavy scale model at high speeds, mimicking the air resistance and flow the booster experiences during flight. The wind tunnel subjected the Super Heavy model, affixed with pressure-measuring sensors, to wind speeds ranging from Mach .7, or about 537 miles per hour, to Mach 1.4, or about 1,074 miles per hour. Mach 1 is the speed that sound waves travel, or 761 miles per hour, at sea level.
      Engineers then measured how Super Heavy model responded to the simulated flight conditions, observing its stability, aerodynamic performance, and more. Engineers used the data to update flight software for flight 3 of Super Heavy and Starship and to refine the exterior design of future versions of the booster. The testing lasted about two weeks and took place earlier in 2024.
      After Super Heavy completes its ascent and separation from Starship HLS on its journey to the Moon, SpaceX plans to have the booster return to the launch site for catch and reuse. The Starship HLS will continue on a trajectory to the Moon.
      To get to the Moon for the Artemis missions, astronauts will launch in NASA’s Orion spacecraft aboard the SLS (Space Launch System) rocket from the agency’s Kennedy Space Center in Florida. Once in lunar orbit, Orion will dock with the Starship HLS or with Gateway. Once the spacecraft are docked, the astronauts will move from Orion or Gateway to the Starship HLS, which will bring them to the surface of the Moon. After surface activities are complete, Starship will return the astronauts to Orion or Gateway waiting in lunar orbit. The astronauts will transfer to Orion for the return trip to Earth. 
      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, 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 Begins New Deployable Solar Array Tech Demo on Pathfinder Spacecraft
      by Gianine Figliozzi
      NASA recently evaluated initial flight data and imagery from Pathfinder Technology Demonstrator-4 (PTD-4), confirming proper checkout of the spacecraft’s systems including its on-board electronics as well as the payload’s support systems such as the small onboard camera. Shown below is a test image of Earth taken by the payload camera, shortly after PTD-4 reached orbit. This camera will continue photographing the technology demonstration during the mission. 
      Payload operations are now underway for the primary objective of the PTD-4 mission – the demonstration of a new power and communications technology for future spacecraft. The payload, a deployable solar array with an integrated antenna called the Lightweight Integrated Solar Array and anTenna, or LISA-T, has initiated deployment of its central boom structure. The boom supports four solar power and communication arrays, also called petals. Releasing the central boom pushes the still-stowed petals nearly three feet (one meter) away from the spacecraft bus. The mission team currently is working through an initial challenge to get LISA-T’s central boom to fully extend before unfolding the petals and beginning its power generation and communication operations.
      A test image of Earth taken by NASA’s Pathfinder Technology Demonstrator-4’s onboard camera. The camera will capture images of the Lightweight Integrated Solar Array and anTenna upon deployment.NASA Small spacecraft on deep space missions require more electrical power than what is currently offered by existing technology. The four-petal solar array of LISA-T is a thin-film solar array that offers lower mass, lower stowed volume, and three times more power per mass and volume allocation than current solar arrays. The in-orbit technology demonstration includes deployment, operation, and environmental survivability of the thin-film solar array.  
      “The LISA-T experiment is an opportunity for NASA and the small spacecraft community to advance the packaging, deployment, and operation of thin-film, fully flexible solar and antenna arrays in space. The thin-film arrays will vastly improve power generation and communication capabilities throughout many different mission applications,” said Dr. John Carr, deputy center chief technologist at NASA’s Marshall Space Flight Center in Huntsville, Alabama. “These capabilities are critical for achieving higher value science alongside the exploration of deep space with small spacecraft.”
      The Pathfinder Technology Demonstration series of missions leverages a commercial platform which serves to test innovative technologies to  increase the capability of small spacecraft. Deploying LISA-T’s thin solar array in the harsh environment of space presents inherent challenges such as deploying large highly flexible non-metallic structures with high area to mass ratios. Performing experiments such as LISA-T on a smaller, lower-cost spacecraft allows NASA the opportunity to take manageable risk with high probability of great return. The LISA-T experiment aims to enable future deep space missions with the ability to acquire and communicate data through improved power generation and communication capabilities on the same integrated array.
      The PTD-4 small spacecraft is hosting the in-orbit technology demonstration called LISA-T. The PTD-4 spacecraft deployed into low Earth orbit from SpaceX’s Transporter-11 rocket which launched from Space Launch Complex 4E at Vandenberg Space Force Base in California on Aug. 16. NASA’s Marshall Space Flight Center in Huntsville, Alabama designed and built the LISA-T technology as well as LISA-T’s supporting avionics system. NASA’s Small Spacecraft Technology program, based at NASA’s Ames Research Center in California’s Silicon Valley and led by the agency’s Space Technology Mission Directorate, funds and manages the PTD-4 mission as well as the overall Pathfinder Technology Demonstration mission series. Terran Orbital Corporation of Irvine, California, developed and built the PTD-4 spacecraft bus, named Triumph.

      Faces of NASA – Ames’ Dr. Donald Mendoza, Chief Engineer
      “From my earliest childhood, flight had always captivated me. I lived out in the boonies and the farmlands, so I didn’t have neighbors to go and play with. If I wasn’t working, I was left to my own devices, and often, I would just be captivated by the wildlife and in particular, the birds of prey that I would see.
      Dr. Donald Menodoza, Chief Engineer, NASA Engineering and Safety Center at Ames.NASA photo by Dominic Hart “To me, they represented a freedom of some kind or another. These birds and the view they have — they can take in so much. So, from that point on, I knew I wanted to be involved in flight and aviation.
      “I [enjoyed] all things flight, all things spaceflight. I couldn’t get enough of it. I became an avid reader, whereas before, I wasn’t much of a reader. I couldn’t get enough material to read about my heroes from flight and space. They became my role models and the path that they took involved, at some point or another, a pretty rigorous education and dedication to doing well academically, physically, or athletically. So, I threw myself into that entire sort of mindset.
      “When I was working for the Air Force, I was able to fly and work on aircraft that I would dream about, looking at in the magazines Aviation Week and Space Technology. Here they are, right in front of me.
      “… So, my career has been as close as possible to that of a flight test engineer. And then, right on the heels of being captivated by atmospheric flight, working in human spaceflight has put me over the Moon.”
      —Dr. Donald Mendoza, Chief Engineer, NASA Engineering & Safety Center, NASA’s Ames Research Center

      We Are All Made of Cells: Space and the Immune System
      by Rachel Hoover
      Malcolm O’Malley and his mom sat nervously in the doctor’s office awaiting the results of his bloodwork. This was no ordinary check-up. In fact, this appointment was more urgent and important than the SATs the seventeen-year-old, college hopeful had spent months preparing for and was now missing in order to understand his symptoms. 
      But when the doctor shared the results – he had off-the-charts levels of antibodies making him deathly allergic to shellfish – O’Malley realized he had more questions than answers. Like: Why is my immune system doing this? How is it working? Why is it reacting so severely and so suddenly (he’d enjoyed shrimp less than a year ago)? And why does the only treatment – an injection of epinephrine – have nothing to do with the immune system, when allergies appear to be an immune system problem? Years later, O’Malley would look to answer some of these questions while interning in the Space Biosciences Research Branch at NASA’s Ames Research Center in California’s Silicon Valley.
      Bone cells NASA/Eduardo Almeida and Cassie Juran “Anaphylaxis is super deadly and the only treatment for it is epinephrine; and I remember thinking, ‘how is this the best we have?’ because epinephrine does not actually treat the immune system at all – it’s just adrenaline,” said O’Malley, who recently returned to his studies as a Ph.D. student of Biomedical Engineering at the University of Virginia (UVA) in Charlottesville. “And there’s a thousand side effects, like heart attacks and stroke – I remember thinking ‘these are worse than the allergy!’”
      O’Malley’s curiosity and desire to better understand the mechanisms and connections between what triggers different immune system reactions combined with his interest in integrating datasets into biological insights inspired him to shift his major from computer science to biomedical engineering as an undergraduate student. With his recent allergy diagnosis and a lifelong connection to his aunt who worked at the UVA Heart and Vascular Center, O’Malley began to build a bridge between the immune system and heart health. By the time he was a senior in college, he had joined the Cardiac Systems Biology Lab, and had chosen to focus his capstone project on better understanding the role of neutrophils, a specific type of immune cell making up 50 to 70% of the immune system, that are involved in cardiac inflammation in high blood pressure and after heart attacks.
      “The immune system is involved in everything,” O’Malley says. “Anytime there’s an injury – a paper cut, a heart attack, you’re sick – the immune system is going to be the first to respond; and neutrophils are the first responders.”

Joseph Wu, Dilip Thomas and Xu Cao, Stanford Cardiovascular Institute O’Malley’s work to determine what regulates the immune system’s interrelated responses – like how one cell could affect other cells or immune processes downstream – provided a unique opportunity for him to support multiple interdisciplinary NASA biological and physical sciences research projects during his 10-week internship at NASA Ames over the summer of 2024. O’Malley applied machine learning techniques to the large datasets the researchers were using from experiments and specimens collected over many years to help identify possible causes of inflammation seen in the heart, brain, and blood, as well as changes seen in bones, metabolism, the immune system, and more when humans or other model organisms are exposed to decreased gravity, social isolation, and increased radiation. These areas are of keen interest to NASA due to the risks to human health inherent in space exploration and the agency’s plans to send humans on long-duration missions to the Moon, Mars, and beyond.
      “It’s exciting that we just never know what’s going to happen, how the immune system is going to react until it’s already been activated or challenged in some way,” said O’Malley. “I’m particularly interested in the adaptive immune system because it’s always evolving to meet new challenges; whether it’s a pandemic-level virus, bacteria or something on a mission to Mars, our bodies are going to have some kind of adaptive immune response.”
      During his NASA internship, O’Malley applied a statistical analysis techniques to plot and make more sense of the massive amounts of life sciences data. From there, researchers could find out which proteins, out of hundreds, or attributes – like differences in sex – are related to which behaviors or outcomes. For example, through O’Malley’s analysis, researchers were able to better pinpoint the proteins involved in inflammation of the brain that may play a protective role in spatial memory and motor control during and after exposure to radiation – and how we might be able to prevent or mitigate those impacts during future space missions and even here on Earth.
      “I had this moment where I realized that since my internship supports NASA’s Human Research Program that means the work I’m doing directly applies to Artemis, which is sending the first woman and person of color to the Moon,” reflected O’Malley. “As someone who’s both black and white, representation is important to me. It’s inspiring to think there will be people like me on the Moon – and that I’m playing a role in making this happen.”
      When O’Malley wasn’t exploring the mysteries of the immune system for the benefit of all at NASA Ames, he taught himself how to ride a bike and started to surf in the nearby waters of the Pacific Ocean. O’Malley considers Palmyra, Virginia, his hometown and he enjoys playing sports – especially volleyball, water polo, and tennis – reading science fiction and giving guest lectures to local high school students hoping to spark their curiosity. 
      O’Malley’s vision for the future of biomedical engineering reflects his passion for innovation. “I believe that by harnessing the unique immune properties of other species, we can achieve groundbreaking advancements in limb regeneration, revolutionize cancer therapy, and develop potent antimicrobials that are considered science fiction today,” he said.
