3 min read Discovery Alert: Glowing Cloud Points to a Cosmic Collision This illustration depicts the aftermath of a collision between two giant exoplanets. What remains is a hot, molten planetary core and a swirling, glowing cloud of dust and debris. Mark A. Garlick The Discovery: A glowing cosmic cloud has revealed a cataclysmic collision. Key Facts: Even within our own solar system, scientists have seen evidence of giant, planetary collisions from long ago. Remaining clues like Uranus’ tilt and the existence of Earth’s moon point to times in our distant history when the planets in our stellar neighborhood slammed together, forever changing their shape and place in orbit. Scientists looking outside our solar system to far off exoplanets can spot similar evidence that, across the universe, planets sometimes crash. In this new study, the evidence of such an impact comes from a cloud of dust and gas with a strange, fluctuating luminosity. Details: Scientists were observing a young (300-million-year-old) Sun-like star when they noticed something odd: the star suddenly and significantly dipped in brightness. A team of researchers looked a little closer and they found that, just before this dip, the star displayed a sudden spike in infrared luminosity. In studying the star, the team found that this luminosity lasted for 1,000 days. But 2.5 years into this bright event, the star was unexpectedly eclipsed by something, causing the sudden dip in brightness. This eclipse endured for 500 days. The team investigated further and found that the culprit behind both the spike in luminosity and the eclipse was a giant, glowing cloud of gas and dust. And the most likely reason for the sudden, eclipse-causing cloud? A cosmic collision between two exoplanets, one of which likely contained ice, the researchers think. In a new study detailing these events, scientists suggest that two giant exoplanets anywhere from several to tens of Earth masses crashed into one another, creating both the infrared spike and the cloud. A crash like this would completely liquify the two planets, leaving behind a single molten core surrounded by a cloud of gas, hot rock, and dust. After the crash, this cloud, still holding the hot, glowing remnant of the collision, continued to orbit the star, eventually moving in front of and eclipsing the star. Fun Facts: This study was conducted using archival data from NASA’s now-retired WISE mission – the spacecraft continues to operate under the name NEOWISE. This star was first detected in 2021 by the ground-based robotic survey ASAS-SN (All-Sky Automated Survey for Supernovae). While this data revealed remnants of this planetary collision, the glow of this crash should still be visible to telescopes like NASA’s James Webb Space Telescope. In fact, the research team behind this study is already putting together proposals to observe the system with Webb. Discoverers: The study, “A planetary collision afterglow and transit of the resultant debris cloud,” was published Oct. 11, 2023, in Nature by lead author Matthew Kenworthy alongside 21 co-authors.

In 1994, a joint NASA and Department of Defense (DOD) mission called Clementine dramatically changed our view of the Moon. As the first U.S. mission to the Moon in more than two decades, Clementine’s primary objectives involved technology demonstrations to test lightweight component and sensor performance. The lightweight sensors aboard the spacecraft returned 1.6 million digital images, providing the first global multispectral and topographic maps of the Moon. Data from a radar instrument indicated that large quantities of water ice may lie in permanently shadowed craters at lunar south pole, while other polar regions may remain in near permanent sunlight. Although a technical problem prevented a planned flyby of an asteroid, Clementine’s study of the Moon proved that a technology demonstration mission can accomplish significant science. Left: The Clementine engineering model on display at the Smithsonian Institution’s National Air and Space Museum (NASM) in Washington, D.C. Image credit: courtesy NASM. Right: Schematic illustration showing Clementine’s major components and sensors. The DOD’s Strategic Defense Initiative Organization, renamed the Ballistic Missile Defense Organization in 1993, directed the Clementine project, formally called the Deep Space Program Science Experiment. The Naval Research Laboratory (NRL) in Washington, D.C., managed the mission design, spacecraft manufacture and test, launch vehicle integration, ground support, and flight operations. The Lawrence Livermore National Laboratory (LLNL) in Livermore, California, provided the nine science instruments, including lightweight imaging cameras and ranging sensors. NASA’s Goddard Space Flight Center in Beltsville, Maryland, provided trajectory and mission planning support for the lunar phase, and NASA’s Jet Propulsion Laboratory in Pasadena, California, provided trajectory and mission planning for the asteroid encounter and deep space communications and tracking through the Deep Space Network. Clementine’s primary planned mission involved the testing of new lightweight satellite technologies in the harsh deep space environment. As a secondary mission, Clementine would observe the Moon for two months using its multiple sensors, then leave lunar orbit and travel to 1620 Geographos, a 1.6-mile-long, elongated, stony asteroid. At a distance of 5.3 million miles from Earth, Clementine would fly within 62 miles of the near-Earth asteroid, returning images and data using its suite of sensors. Left: Technicians prepare Clementine for a test in an anechoic chamber prior to shipping to the launch site. Middle: Workers lower the payload shroud over Clementine already mounted on its Titan IIG launch vehicle. Right: Liftoff of Clementine from Vandenberg Air Force, now Space Force, Base in California. The initial idea behind a joint NASA/DOD technology demonstration mission began in 1990, with funding approved in March 1992 to NRL and LLNL to start design of Clementine and its sensors, respectively. In an incredibly short 22 months, the spacecraft completed design, build, and testing to prepare it for flight. Clementine launched on Jan. 25, 1994, from Space Launch Complex 4-West at Vandenberg Air Force, now Space Force, Base in California atop a Titan IIG rocket. Trajectory of Clementine from launch to lunar orbit insertion. Image credit: courtesy Lawrence Livermore National Laboratory. The spacecraft spent the next eight days in low Earth orbit checking out its systems. On Feb. 3, a solid rocket motor fired to place it on a lunar phasing loop trajectory that included two Earth flybys to gain enough energy to reach the Moon. During the first orbit, the spacecraft jettisoned the Interstage Adapter Subsystem that remained in a highly elliptical Earth orbit for three months collecting radiation data as it passed repeatedly through the Van Allen radiation belts. On Feb. 19, Clementine fired its own engine to place the spacecraft into a highly elliptical polar lunar orbit with an 8-hour period. A second burn two days later placed Clementine into its 5-hour mapping orbit. The first mapping cycle began on Feb. 26, lasting one month, and the second cycle ended on April 21, followed by special observations. Left: Composite image of the Moon’s south polar region. Middle left: Image of Crater Tycho. Middle right: Image of Crater Rydberg. Right: Composite image of the Moon’s north polar region. During the first month of mapping, the low point of Clementine’s orbit was over the southern hemisphere to enable higher resolution imagery and laser altimetry over the south polar regions. Clementine adjusted its orbit to place the low point over the northern hemisphere for the second month of mapping to image the north polar region at higher resolution. Clementine spent the final two weeks in orbit filling in any gaps and performing extra studies looking for ice in the north polar region. For 71 days and 297 lunar orbits, Clementine imaged the Moon, returning 1.6 million digital images, many at a resolution of 330 feet. It mapped the Moon’s entire surface including the polar regions at wavelengths from near ultraviolet through visible to far infrared. The laser altimetry provided the first global topographic map of the Moon. Similar data from Apollo missions only mapped the equatorial regions of the Moon that lay under the spacecraft’s orbital path. Radio tracking of the spacecraft refined our knowledge of the Moon’s gravity field. A finding with significant application to future exploration missions, Clementine found areas near the polar regions where significant amounts of water ice may exist in permanently shadowed crater floors. Conversely, Clementine found other regions near the poles that may remain in near perpetual sunlight, providing an abundant energy source for future explorers. The Dec. 16, 1994, issue of Science, Vol. 266, No. 5192, published early results from Clementine. The Clementine project team assembled a series of lessons learned from the mission to aid future spacecraft development and operations. Left: A global map of the Moon created from Clementine images. Right: A global topographic map of the Moon based on Clementine data. Left: Composite image of Earth taken by Clementine from lunar orbit. Middle left: Colorized image of the full Earth over the lunar north pole. Middle right: Color enhanced view of the Moon lit by Earth shine, the solar corona, and the planet Venus. Right: Color enhanced image of the Earthlit Moon, the solar corona, and the planets Saturn, Mars, and Mercury. Its Moon observation time over, Clementine left lunar orbit on May 5, heading for Geographos via two more Earth gravity-assist flybys. Unfortunately, two days later a computer glitch caused one of the spacecraft’s attitude control thrusters to misfire for 11 minutes, expending precious fuel and sending Clementine into an 80-rotations-per-minute spin. The problem would have significantly reduced data return from the asteroid flyby planned for August and managers decided to keep the spacecraft in an elliptical geocentric orbit. A power supply failure in June rendered Clementine’s telemetry unintelligible. On July 20, lunar gravity propelled the spacecraft into solar orbit and the mission officially ended on Aug. 8. Ground controllers briefly regained contact between Feb. 20 and May 10, 1995, but Clementine transmitted no useful data. Despite the loss of the Geographos flyby, Clementine left a lasting legacy. The mission demonstrated that a flight primarily designed as a technology demonstration can accomplished significant science. The data Clementine returned revolutionized our knowledge of lunar history and evolution. The discovery of the unique environments at the lunar poles, including the probability of large quantities of water ice in permanently shadowed regions there, changed the outlook for future scientific missions and human exploration. Subsequent science missions, such as NASA’s Lunar Prospector and Lunar Reconnaissance Orbiter, China’s Chang’e spacecraft, and India’s Chandrayaan spacecraft, all built on the knowledge that Clementine first obtained. Current uncrewed missions target the lunar polar regions to add ground truth to the orbital observations, and NASA’s Artemis program intends to land the first woman and the first person of color in that region as a step toward sustainable lunar exploration.

The Orion spacecraft for NASA’s Artemis II mission received its latest makeover. Teams adhered the agency’s iconic “worm” logo and ESA (European Space Agency) insignia on the spacecraft’s crew module adapter on Sunday, Jan. 28, inside the Neil Armstrong Operations and Checkout Building at NASA’s Kennedy Space Center in Florida.NASA/Rad Sinyak NASA’s iconic “worm” logo and ESA’s (European Space Agency) insignia are painted on the Orion spacecraft’s crew module adapter in this image from Feb. 1, 2024. The adapter houses electronic equipment for communications, power, and control, and includes an umbilical connector that bridges the electrical, data, and fluid systems between the main modules. In October 2023, technicians joined the crew and service modules together. The crew module will house the four Artemis II astronauts as they journey around the Moon and back to Earth on an approximately 10-day trip. The spacecraft’s service module, provided by ESA, will supply the vehicle with electricity, propulsion, thermal control, air, and water in space. See photos of the crew module adapter and the SLS (Space Launch System) solid rocket boosters, which were also recently adorned with the “worm” logo.

All the major structures that will form the core stage for NASA’s SLS (Space Launch System) rocket for the agency’s Artemis III mission are structurally complete. Technicians finished welding the 51-foot liquid oxygen tank structure, left, inside the Vertical Assembly Building at NASA’s Michoud Assembly Facility in New Orleans Jan. 8. The liquid hydrogen tank, right, completed internal cleaning Nov. 14. NASA/Michael DeMocker As NASA works to develop all the systems needed to return astronauts to the Moon under its Artemis campaign for the benefit of all, the SLS (Space Launch System) rocket will be responsible for launching astronauts on their journey. With the liquid oxygen tank now fully welded, all of the major structures that will form the core stage for the SLS rocket for the agency’s Artemis III mission are ready for additional outfitting. The hardware will be a part of the rocket used for the first of the Artemis missions planning to land astronauts on the Moon’s surface near the lunar South Pole. Technicians finished welding the 51-foot liquid oxygen tank structure inside the Vertical Assembly Building at NASA’s Michoud Assembly Facility in New Orleans Jan. 8. The mega rocket’s other giant propellant tank – the liquid hydrogen tank – is already one fully welded structure. NASA and Boeing, the SLS core stage lead contractor, are currently priming the tank in another cell within the Vertical Assembly Building area called the Building 131 cryogenic tank thermal protection system and primer application complex. It completed internal cleaning Nov. 14. Manufacturing hardware is a multi-step process that includes welding, washing, and, later, outfitting hardware.The internal cleaning process is similar to a shower to ensure contaminants do not find their way into the stage’s complex propulsion and engine systems prior to priming. Once internal cleaning is complete, primer is applied to the external portions of the tank’s barrel section and domes by an automated robotic tool. Following primer, technicians apply a foam-based thermal protection system to shield it from the extreme temperatures it will face during launch and flight while also regulating the super-chilled propellant within. “NASA and its partners are processing major hardware elements at Michoud for several SLS rockets in parallel to support the agency’s Artemis campaign,” said Chad Bryant, acting manager of the Stages Office for NASA’s SLS Program. “With the Artemis II core stage nearing completion, the major structural elements of the SLS core stage for Artemis III will advance through production on the factory floor.” The two massive propellant tanks for the rocket collectively hold more than 733,000 gallons of super-chilled propellant. The propellant powers the four RS-25 engines and must stay extremely cold to remain liquid. The core stage, along with the RS-25 engines, will produce two million pounds of thrust to help launch NASA’s Orion spacecraft, astronauts, and supplies beyond Earth’s orbit and to the lunar surface for Artemis III. SLS is the only rocket that can send Orion, astronauts, and supplies to the Moon in a single launch. Through Artemis, NASA will send astronauts—including the first woman, first person of color, and first international partner astronaut—to explore the Moon for scientific discovery, economic benefits, and to build the foundation for crewed mission to Mars. SLS is part of NASA’s backbone for deep space exploration, along with the Orion spacecraft, exploration ground systems, advanced spacesuits and rovers, Gateway, and human landing systems.

2 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) NASA’s Stennis Space Center and Sidus Space, Inc., marked another milestone February 15 for the Center’s first-ever in-flight autonomous systems software mission as a payload rider on the Sidus Space LizzieSatTM small satellite. “Each step brings us a step closer to deployment of ASTRA (Autonomous Satellite Technology for Resilient Applications) in space,” said Chris Carmichael, NASA Stennis Autonomous Systems Laboratory (ASL) Branch Chief. “We are excited with the progress as we continue to collaborate with Sidus Space on this truly historic mission for the Center.” The ASTRA mission involves an autonomous systems hardware/software payload developed at NASA Stennis as a technology demonstrator in space aboard the Sidus Space premier satellite, LizzieSat TM -1 (LS-1). Sidus Space is responsible for the launch, deployment, and mission operation of the LS-1 satellite. At some stage during the overall satellite mission that could last as long as two years, the NASA Stennis team will send commands to the Sidus Space flight computer to autonomously conduct targeted mission objectives with the ASTRA system. In preparation for the scheduled launch of the LS-1 mission this spring, officials at the Sidus Space integration facility in Cape Canaveral, Florida, reported it has completed integration testing of the ASTRA flight unit with the LS-1 satellite. Sidus Space worked with members of the NASA Stennis ASL team to complete extensive integration and communications testing of the flight unit. The testing verified unit functionality, as well as the ability of the ASL team to upload software to the flight unit. The latest achievement comes on the heels of a December milestone in which the ASL team completed a Flight Readiness Review of the baseline ASTRA flight software. Sidus Space is scheduled to launch the LS-1 satellite on the SpaceX Transporter 10, Falcon 9 rocket, this spring. LS-1 will be among dozens of small satellites launched on the SpaceX rocket. The LS-1 satellite is carrying six payloads to space, one of which is ASTRA. The ASTRA project began as a proposal by early career employees at NASA Stennis and continues as a partnership project between the Center and Sidus Space. It marks the first time NASA Stennis ever has flown hardware/software into space.

Credit: NASA/Josh Valcarcel NASA is seeking applicants to participate in its next simulated one-year Mars surface mission to help inform the agency’s plans for human exploration of the Red Planet. The second of three planned ground-based missions called CHAPEA (Crew Health and Performance Exploration Analog) is scheduled to kick off in spring 2025. Each CHAPEA mission involves a four-person volunteer crew living and working inside a 1,700-square-foot, 3D-printed habitat based at NASA’s Johnson Space Center in Houston. The habitat, called the Mars Dune Alpha, simulates the challenges of a mission on Mars, including resource limitations, equipment failures, communication delays, and other environmental stressors. Crew tasks include simulated spacewalks, robotic operations, habitat maintenance, exercise, and crop growth. NASA is looking for healthy, motivated U.S. citizens or permanent residents who are non-smokers, 30-55 years old, and proficient in English for effective communication between crewmates and mission control. Applicants should have a strong desire for unique, rewarding adventures and interest in contributing to NASA’s work to prepare for the first human journey to Mars. The deadline for applicants is Tuesday, April 2. https://chapea.nasa.gov/ Crew selection will follow additional standard NASA criteria for astronaut candidate applicants. A master’s degree in a STEM field such as engineering, mathematics, or biological, physical or computer science from an accredited institution with at least two years of professional STEM experience or a minimum of one thousand hours piloting an aircraft is required. Candidates who have completed two years of work toward a doctoral program in science, technology, engineering, and mathematics, completed a medical degree, or a test pilot program will also be considered. With four years of professional experience, applicants who have completed military officer training or a bachelor of science degree in a STEM field may be considered. Compensation for participating in the mission is available. More information will be provided during the candidate screening process. As NASA works to establish a long-term presence for scientific discovery and exploration on the Moon through the Artemis campaign, CHAPEA missions provide important scientific data to validate systems and develop solutions for future missions to the Red Planet. With the first CHAPEA crew more than halfway through their yearlong mission, NASA is using research gained through the simulated missions to help inform crew health and performance support during Mars expeditions. Under NASA’s Artemis campaign, the agency will establish the foundation for long-term scientific exploration at the Moon, land the first woman, first person of color, and its first international partner astronaut on the lunar surface, and prepare for human expeditions to Mars for the benefit of all.

3 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) In the dawn of the Space Age, a group of scientists and engineers from the Naval Research Laboratory (NRL) had their eye on a new frontier: the uncharted expanse of space. Project Vanguard, initiated in 1955, aimed to launch the first American satellite into Earth orbit as part of the International Geophysical Year (July 1957 to December 1958). Led by NRL, it envisioned a three-stage rocket design and emphasized scientific instrumentation over military application while showcasing American ingenuity. Despite its ambitious goals, Project Vanguard encountered difficulties. The first five Vanguard launch attempts suffered critical failures, earning it the nickname “Flopnik” in the press. The public, eager for American success in space following the Soviet Union’s launch of Sputnik 1, was disappointed in Vanguard’s performance. However, Vanguard’s legacy extends beyond its initial setbacks. On March 17, 1958, Vanguard TV-4, also known as Vanguard I, achieved orbit to become America’s second satellite and the world’s fourth artificial satellite in space. This success marked a major milestone and instilled renewed confidence in the project. Today, Vanguard I remains in space as the oldest satellite orbiting the Earth. The Vanguard II satellite is prepared for launch on the Vanguard SLV-4 rocket in early 1959. NASA Goddard Archives The sphere-shaped Vanguard II satellite reflects the scene in this 1959 photo from the preparations for its launch.NASA Goddard Archives A few months after the launch of Vanguard I in 1958, the National Aeronautics and Space Act was passed establishing the National Aeronautics and Space Administration (NASA), and on May 1, 1959, NASA Administrator Dr. T. Keith Glennan announced that the Beltsville Space Center would become Goddard Space Flight Center. The center would be under the overall guidance of Dr. Abe Silverstein, then Director of Space Flight Development at NASA Headquarters. Recognizing the expertise and dedication of the NRL team, NASA transferred many employees from Project Vanguard to form the nucleus of the Goddard Space Flight Center in Greenbelt, Maryland. The migration of NRL scientists and engineers to Goddard wasn’t merely a paperwork shuffle, it was the transfer of their vital knowledge and experience. Their impact was immediate. While initially tasked with completing Vanguard’s mission, the Goddard center quickly expanded its scope, encompassing Earth science, astrophysics, and space exploration. Early Goddard employees formed the core of several projects, including the Explorer series of satellites and the Television Infrared Observation Satellite (TIROS) Program. They tackled the challenges of satellite communication, laying the groundwork for technologies that would be used for years. Goddard’s dedication ceremony took place on March 16, 1961, but its employees were hard at work well before that day. According to one employee’s account, the Applied Mathematics Branch moved from an office in Anacostia to the Greenbelt site on May 9, 1960. Other employees from a Massachusetts Avenue office building in Washington, DC, arrived around the same time. Those early days at Goddard were not easy. Parking lots had not been paved and signs at the center directed employees to park their cars under a large grove of oak trees. Some buildings did not yet have running water and portable toilets were available outside. The parking area outside Building 1 at Goddard Space Flight Center circa 1960 left room for improvement. NASA Goddard Archives Portable toilets were also parked outside Building 1 circa 1960 when running water at the site was still unavailable.NASA Goddard Archives In celebration of Vanguard II’s sixtieth anniversary in 2019, the Goddard Archives installed newly preserved flight spares of Vanguard II and Vanguard III. Vanguard II hangs in the atrium of Building 33 and Vanguard III hangs in the visitor’s center. The Goddard Archives also hosted an event to highlight Goddard’s roots in Project Vanguard. In attendance were NRL historian Angelina Callahan, who gave a short talk about NRL and Project Vanguard, and five employees who worked at Goddard when it was first established. The legacy of the early work at NASA Goddard endures, not just in its scientific achievements, but also in its inspiring work exploring the frontiers of our universe. Five of the original employees at Goddard Space Flight Center participated in a celebration of Vanguard II’s sixtieth anniversary in 2019.

“I was born and raised in Kenya and come from a very humble background. I’m one of nine kids and the third born, meaning that I started responsibilities very early because we had to help our mother. Almost every two to three years, she had a baby, so you can imagine she was a very, very strong woman and powerful, too. When I think about that past, she is the person, and my father as well, who taught us that we can overcome any obstacle. It doesn’t matter what it is. “I remember going to school without fees, and they would send me home. One time, when I was complaining about being sent home because of my lack of school fees, [my mother] could see I was affected by all this. She told me, ‘Those kids you see out there that look like they come from higher, well-off families came to this world the same way you came. So, you are no different than them. Don’t look at the material wealth and think you are less than them.’ “That’s the background that shaped me. It instilled a sense of believing in yourself. Anyone you see on the streets, their color or background doesn’t matter; we all come into this world the same way. You’re equipped with skills, so find your passion and go for it. “When I look at that background, it’s the one that has helped me come this far.” – Dr. Charles Gatebe, Chief of Atmospheric Science Branch, NASA’s Ames Research Center Image Credit: NASA / Brandon Torres Interviewer: NASA / Tahira Allen Check out some of our other Faces of NASA.

Check out what Shobhana has to say about open innovation and the NASA Spark community. What is your role at NASA? I serve as the Manager of NASA Earth Action’s Prizes and Challenges Program, where we use crowdsourcing mechanisms to invite talents and experiences outside of the NASA community to participate in the discovery and development of Earth observations-based applications for decision-making. I also serve as the Associate Program Manager of NASA’s Equity and Environmental Justice Program, to support projects that apply NASA data for advancing awareness and challenges related to human health or environmental outcomes that are unique to, or disproportionately affect, underserved communities, including persons of color, low-income persons, Indigenous persons or members of Tribal nations. I completed my medical and graduate training at Vanderbilt University School of Medicine (Department of Microbiology and Immunology) and a postdoctoral fellowship at Yale University School of Medicine (Department of Neurology) before joining NASA in 2015 as an AAAS Science and Technology Policy Fellow. I supported the Health and Air Quality Program to enhance decision-making about environmental health and infectious diseases, as well as managed NASA’s International Space Apps Challenge Program in 2017. Why do you like participating on NASA Spark? I truly believe that the best outcomes can be achieved if we are open and invite collaboration on not just the work we have done, but the work that we are doing. This includes sharing our current challenges and harnessing the knowledge and skills of people from different backgrounds, fields of expertise, and different experiences to find solutions. Instead of trying to find resources or solutions by myself or within my team, NASA Spark allows me to expand my network and benefit from ideas from colleagues across ALL of NASA – that’s incredible! You’re a multi-time winner! What does that mean to you? Why do you keep coming back and sharing your ideas? I love participating in NASA Spark campaigns because it is a great way to leverage the work we are doing or have completed for greater impact across NASA. If we have created a resource that gives another team a head start in their work, it’s a win-win. Our team can show the value of our work, and the other team can save their time and resources. How can other NASA employees best utilize NASA Spark? NASA Spark can be the NASA “watercooler” for employees across all programs and centers in the agency. We can post challenges we are stuck on, ideas we are trying to develop, or any other calls for input to our entire brilliant, skilled, multidisciplinary expert workforce – for free and for minimal effort! We should all sign up to learn about and contribute to new campaigns from our colleagues, including building on ideas that others have submitted. NASA Spark is a great platform to network across the agency – your coworkers are just collaborators waiting to happen! What does innovation mean to you? Innovation, to me, is doing something new while constantly moving towards doing better. Whether it is applying existing tools and ideas in a novel way or developing completely new solutions – innovation should make our work easier and outcomes more impactful. Open innovation by sharing our work and challenges with people from unrelated fields and backgrounds, encouraging them to apply their perspectives to manipulate our questions and share solutions, can in turn empower us to achieve superior outcomes.

In the left two photos, workers with NASA’s Exploration Ground Systems (EGS) paint the bright red NASA “worm” logo on the side of an Artemis II solid rocket booster segment inside the Rotation, Processing and Surge Facility (RPSF) at Kennedy Space Center in Florida on Tuesday, Jan. 30, 2024. The EGS team used a laser projector to mask off the logo with tape, then painted the first coat of the iconic design. The booster segments will help propel the Space Launch System (SLS) rocket on the Artemis II mission to send four astronauts around the Moon as part of the agency’s effort to establish a long-term science and exploration presence at the Moon, and eventually Mars. In the right photo, the Orion spacecraft for NASA’s Artemis II mission received its latest makeover. Teams adhered the agency’s iconic “worm” logo and ESA (European Space Agency) insignia on the spacecraft’s crew module adapter on Sunday, Jan. 28, inside the Neil Armstrong Operations and Checkout Building at NASA’s Kennedy Space Center in Florida.NASA/Glenn Benson and Rad Sinyak Art and science merge as teams add the NASA “worm” logo on the SLS (Space Launch System) solid rocket boosters and the Orion spacecraft’s crew module adapter at NASA’s Kennedy Space Center in Florida for the agency’s Artemis II mission. The iconic logo was introduced in 1975 by the firm of Danne & Blackburn as a modern emblem for the agency. It emerged from a nearly 30-year retirement in 2020 for limited use on select missions and products. NASA’s Exploration Ground Systems and prime contractor Jacobs began painting the red logotype onto the segments that form the Moon rocket’s two solid rocket boosters Jan. 22. To do so, crews used a laser projector to first mark off the location of the logo with tape, then applied two coats of paint and finished by adding several coats of clear primer. Each letter of the worm logo measures approximately 6 feet and 10 inches in height and altogether, stretches 25 feet from end to end, or a little less than the length of one of the rocket’s booster motor segments. The location of the worm logo will be moderately different from where it was during Artemis I. While it will still be located on each of the rocket’s 17 story boosters, the modernist logo will be placed toward the front of the booster systems tunnel cover. The SLS boosters are the largest, most powerful solid propellant boosters ever flown and provide more than 75% of the thrust at launch.

2 min read Hubble Views a Massive Star Forming This image from the NASA/ESA Hubble Space Telescope is a relatively close star-forming region known as IRAS 16562-3959. ESA/Hubble & NASA, R. Fedriani, J. Tan This image from the NASA/ESA Hubble Space Telescope is teeming with color and activity. It features a relatively close star-forming region known as IRAS 16562-3959, which lies within the Milky Way about 5,900 light-years from Earth in the constellation Scorpius. Observations from Hubble’s Wide Field Camera 3 make up this image. Its detailed nuance of color is the result of four separate filters. These thin slivers of highly specialized material can slide in front of the instrument’s light sensors, allowing very specific wavelengths of light to pass through with each observation. This is useful because certain wavelengths of light can tell us about the region’s composition, temperature, and density. At the center of the image, IRAS 16562-3959 likely hosts a massive star – about 30 times the mass of our Sun – that is still in the process of forming. The shadowy clouds appear dark because there is so much light-obscuring dust blocking the near-infrared wavelengths of light Hubble observed. However, near-infrared light does leak out mainly on two sides – upper left and lower right – where a powerful jet from the massive protostar cleared away the dust. Multi-wavelength images like this incredible Hubble scene help us gain a better understanding of how the most massive, brightest stars in our galaxy form.

Credit: NASA Earth Observatory image by Joshua Stevens, using Landsat data from the U.S. Geological Survey, and MODIS data from NASA EOSDIS/LANCE and GIBS/Worldview. NASA is now an associate member of the National Wildfire Coordinating Group, giving the agency new opportunities to collaborate with federal agencies and other partners to better understand wildland fires and leverage technology and innovation to prevent and manage them for the benefit of humanity. The interagency group provides national leadership to enable interoperable wildland fire operations among federal, state, local, tribal, and territorial partners. The group works to support the National Cohesive Wildland Fire Management Strategy’s goals of restoring and maintaining resilient landscapes, creating fire-adapted communities, and responding to wildfires safely and effectively. “As wildfires become larger and more frequent, NASA is working to apply our scientific and technological knowledge toward this national challenge, and integral to our approach is forging collaborative partnerships,” said NASA Deputy Administrator Pam Melroy. “Harnessing our Earth observation capabilities and cutting-edge technology in safe air operations, we are poised to make new connections that will bolster wildfire fighting efforts across the government.” NASA’s inclusion in the coordination group is a step toward enhancing interagency collaboration. As a member, NASA will have opportunities to develop solutions with wildland fire management agencies as partners to share its research and technologies to aid in the development of standards for wildland fire management. NASA has a rich history of research, development, and technology transfer in the areas of Earth science, space technologies, and aeronautics that will support the group’s mission. To support the National Wildfire Coordinating Group, NASA will leverage the combined contributions of research and development, data gathering and distribution, and technology transfer from three NASA mission directorates in the areas of earth science, space technologies, and aeronautics. The interagency group membership will help augment NASA’s Wildland Fire Management Initiative, which supports the development, demonstration, and commercialization of wildland fire technology through awards to small businesses, research institutions, and other technology innovators. “A crucial aspect of the National Wildfire Coordination Group’s role is developing standards for the wildland fire community to enable interoperability,” said Aitor Bidaburu, executive board chair for the group. “With NASA, it will significantly enhance the common operating framework for the interagency wildland fire community.” NASA’s inclusion also directly supports recommendations the President’s Council of Advisors on Science and Technology made in their 2023 report Modernizing Wildland Firefighting to Protect our Firefighters. Specifically, it recommends agencies: Immediately assess, adapt, and field currently available technologies Strengthen the full operational sequence of wildland firefighting Accelerate improvement of predictive wildfire modeling tools Encourage development and field demonstration of prototype systems to expand the nation’s wildfire response capacity Primary members of the coordination group include the Department of Agriculture Forest Service, Bureau of Indian Affairs, Bureau of Land Management, National Park Service, U.S. Fish and Wildlife Service, National Association of State Foresters, U.S. Fire Administration, Intertribal Timber Council, the International Association of Fire Chiefs, and the Defense Department. Associate members include the Commerce Department’s National Weather Service, and the Department of the Interior’s Office of Wildland Fire. -end- Rob Margetta Headquarters, Washington 202-763-5012 robert.j.margetta@nasa.gov Share Details Last Updated Feb 15, 2024 EditorJennifer M.

3 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) A computer generated image of objects in Earth orbit that are currently being tracked. Credits: NASA ODPO NASA’s Office of Technology, Policy & Strategy is soliciting research and analysis related to the social, economic and policy aspects of space sustainability. This topic area is further refined into two separate elements: orbital space sustainability and lunar surface sustainability. OTPS will provide up to $300K (orbital) and $200K (lunar surface) for between 1-3 proposals in each element. Key questions are featured below. Orbital Space Sustainability: Economic, Social and Policy Research and Analyses Proposals should be responsive to one of the following questions: What are current policy, regulatory or legal gaps to improve space sustainability in various orbital regimes (LEO, MEO, GEO, Cislunar, and/or Lunar) and what specific measures should be taken to address them? Proposers may address one or several orbital regimes. Considering various scenarios for the space environment in the 2040 timeframe, what policies, regulations or other support are forecasted to be needed? Research should take into consideration that potential policies for space sustainability may be incentivized or rendered unnecessary by advancements in technological capabilities and differing assumptions about the future operational environment; therefore, the research should assess the robustness of various policy proposals under realistic assumptions. What are the costs to spacecraft operators from interacting with debris in GEO and Cislunar space? What are the benefits of potential risk-reducing actions? How effective are various policy tools and mechanisms (for example, performance bonds, incentives to improve PMD compliance/fees for bad behavior, global minimum tax, and environmental liability insurance)? How might such interventions impact the business of satellite owners and operators or government owners and operators? Lunar Surface Sustainability: Economic, Social and Policy Research and Analyses The sustainable development of the lunar surface acknowledges that current operations may impact our ability to conduct future operations (indeed current operations may also impact other current operations. Whether we seek to protect critical areas for scientific investigation (e.g., Permanently Shadowed Regions), preserve lunar heritage areas (e.g., Apollo sites) or incorporate other technical, economic, or cultural considerations may all factor into our mission planning, policy and potential regulatory approaches. Analyses may help disentangle and characterize the goals of sustainability, develop frameworks for evaluating the sustainability of operations, or compare and contrast the different definitions of sustainability. Proposals should consider both human and robotic missions. All proposals must be submitted to one of the ROSES calls (F.21 or F.17) by May 17, 2024. Proposers can submit different proposals to each element. However, duplicate proposals submitted to both elements will only be considered for a single element (NASA will make most appropriate determination).

Feb. 15, 2024 RELEASE: J24-003 NASA Selects Texas A&M as First Approved Exploration Park Facility NASA and the Texas A&M University System announced an agreement Thursday, Feb. 15, to lease underutilized land in Exploration Park, a 240-acre development at the agency’s Johnson Space Center in Houston. The A&M System will develop a facility to enable human spaceflight research and development that enables the commercial space economy. The lease agreement will allow the A&M System and others to use NASA Johnson land to create facilities for a collaborative development environment that increases commercial access and enhances the United States’ commercial competitiveness in the space and aerospace industries. NASA Johnson Director Vanessa Wyche, Texas A&M University System Chancellor John Sharp, and Texas A&M University President Mark Welsh III announced the new collaboration at the AIAA-hosted Ascend Texas (ASCENDxTexas) Conference at South Shore Harbour Conference Center. “For more than 60 years, NASA Johnson has been the hub of human sI have paceflight,” Wyche said. “Exploration Park will be the next spoke in the larger wheel of a robust and durable space economy that will benefit not only exploration of the Moon, Mars and the asteroids, but all of humanity as the benefits of space exploration research roll home to Earth.” As the home of Mission Control Center for the agency’s human space missions, astronaut training, human health and space medicine, and leadership of premiere human spaceflight programs and missions, NASA Johnson leads the way for human space exploration. Leveraging this unique role and location, Exploration Park will play a key role in helping the human spaceflight community attain U.S. goals for the commercialization and development of a robust space economy by creating an infrastructure that fosters a multi-use environment where academic researchers, aerospace companies and entrepreneurs can collaborate with NASA and solve space exploration’s greatest challenges. “The Texas A&M University System has a long history of supporting space-related research, and Texas A&M University has been a space grant university since 1989,” Sharp said. “This new agreement and planned facility will allow us to build on our space tradition and help us to be a major part of the commercial space economy.” NASA issued an announcement for proposals for use of the undeveloped and underutilized land near Saturn Lane on June 9, 2023, and has just completed negotiations with the Texas A&M University System Board of Regents to formalize the lease agreement. The parcel is outside of Johnson’s controlled access area and adjacent to its main campus. NASA will lease the land to the A&M System for an initial period of 20 years, with two additional 20-year options, for a potential total of 60 years. “For the last 35 years, Texas A&M University has honored its space-grant mission by becoming a powerhouse in human and robotic space exploration,” Welsh said. “This agreement enables us to leverage faculty expertise, establish strategic partnerships and develop resources to foster new discoveries, technological innovations and a future workforce that will benefit Texas and the nation. We are grateful to NASA, the Board of Regents and the State of Texas for their vision and support of Texas A&M’s work in space exploration.” In the coming years, NASA and its academic, commercial, and international partners will see the completion of the International Space Station Program, the commercial development of low Earth orbit, and the first human Artemis campaign missions establishing a sustainable human presence on the Moon in preparation for human missions to Mars. Johnson already is leading the commercialization of space with the commercial cargo and crew programs and private astronaut missions to the space station. The center also is supporting the development of commercial space stations in low Earth orbit, and lunar-capable commercial spacesuits and lunar landers that will be provided as services to both NASA and the private sector to accelerate human access to space. Through the development of Exploration Park, the center will broaden the scope of the human spaceflight community that is tackling the many difficult challenges ahead. -end- Kelly Humphries Johnson Space Center, Houston 281-483-5111 kelly.o.humphries@nasa.gov View the full article

The New Shepard crew capsule descends under parachutes during its launch Tuesday, Dec. 19, 2023.Photo Credit: Blue Origin Researchers are studying data from a recent suborbital flight test to better understand lunar regolith, or Moon dust, and its potentially damaging effects as NASA prepares to send astronauts back to the lunar surface under the Artemis campaign. The experiment, developed jointly by NASA and the University of Central Florida, sheds light on how these abrasive dust grains interact with astronauts, their spacesuits, and other equipment on the Moon. The Electrostatic Regolith Interaction Experiment (ERIE) was one of 14 NASA-supported payloads launched on Dec. 19 aboard Blue Origin’s New Shepard uncrewed rocket from Launch Site One in West Texas. During the flight test, ERIE collected data to help researchers at the agency’s Kennedy Space Center in Florida study tribocharging, or friction-induced charges, in microgravity. The Moon is highly charged by phenomena such as solar wind and ultraviolet light from the Sun. Under those conditions, regolith grains are attracted to lunar explorers and their equipment – think of it as similar to the static created by rubbing a balloon on a person’s head. Enough regolith can cause instruments to overheat or not function as intended. “For example, if you get dust on an astronaut suit and bring it back into the habitat, that dust could unstick and fly around the cabin,” said Krystal Acosta, a researcher for NASA’s triboelectric sensor board component inside the ERIE payload. “One of the major problems is that there’s no way to electrically ground anything on the Moon. So even a lander, rover, or really any object on the Moon will have polarity to it. There’s no good solution to the dust charging problem right now.” A Kennedy team designed and built the triboelectric sensor board inside the ERIE payload, which reached an altitude of 351,248 feet aboard New Shepard. In the microgravity phase of this flight, dust grains simulating regolith particles brushed up against eight insulators within ERIE, creating a tribocharge. The electrometer measured the negative and positive charge of the simulated regolith as it traveled through an electric field applied during microgravity. “We want to know what causes the dust to charge, how it moves around, and where it ultimately settles. The dust has rough edges that can scratch surfaces and block thermal radiators,” said Jay Phillips, lead of Electrostatics Environments and Spacecraft Charging at NASA Kennedy. University of Central Florida (UCF) and NASA physicists who worked on the ERIE payload pose with Blue Origin booster after launch Tuesday, Dec. 19, 2023. From left to right, Addie Dove, UCF PI for ERIE, Krystal Acosta, NASA researcher, and Jay Phillips, NASA researcher. The ERIE payload spent approximately three minutes in microgravity during the New Shepard capsule’s suborbital flight, which lasted about 10 minutes before landing safely back on Earth in the Texas desert. A camera recorded the interactions, and Philips and his team are reviewing the data. The results will inform applications for future missions destined for the lunar surface. For example, by using triboelectric sensors on a rover’s wheels, astronauts can measure the positive and negative charges between the vehicle and regolith on the lunar surface. The end goal is to develop technologies that will help keep it from sticking to and damaging astronaut suits and electronics during missions. The flight was supported by the Flight Opportunities program, part of NASA’s Space Technology Mission Directorate, which rapidly demonstrates space technologies with industry flight providers.

A SpaceX Falcon 9 rocket carrying Intuitive Machines’ Nova-C lunar lander lifts off from Launch Pad 39A at NASA’s Kennedy Space Center in Florida at 1:05 a.m. EST on Feb. 15, 2024. As part of NASA’s CLPS (Commercial Lunar Payload Services) initiative and Artemis campaign, Intuitive Machines’ first lunar mission will carry NASA science and commercial payloads to the Moon to study plume-surface interactions, space weather/lunar surface interactions, radio astronomy, precision landing technologies, and a communication and navigation node for future autonomous navigation technologies. A suite of NASA science instruments and technology demonstrations is on the way to our nearest celestial neighbor for the benefit of humanity. Through this flight to the Moon, they will provide insights into the lunar surface environment and test technologies for future landers and Artemis astronauts. At 1:05 a.m. EST on Thursday, Intuitive Machines’ Nova-C lander launched on a SpaceX Falcon 9 rocket from Launch Complex 39A at the agency’s Kennedy Space Center in Florida. At approximately 1:53 a.m., the lander deployed from the Falcon 9 second stage. Teams confirmed it made communications contact with the company’s mission operations center in Houston. The spacecraft is stable and receiving solar power. These deliveries are part of NASA’s CLPS (Commercial Lunar Payload Services) initiative and Artemis campaign, which includes new solar system science to better understand planetary processes and evolution, search for evidence of water and other resources, and support long-term human exploration. “NASA scientific instruments are on their way to the Moon – a giant leap for humanity as we prepare to return to the lunar surface for the first time in more than half a century,” said NASA Administrator Bill Nelson. “These daring Moon deliveries will not only conduct new science at the Moon, but they are supporting a growing commercial space economy while showing the strength of American technology and innovation. We have so much to learn through CLPS flights that will help us shape the future of human exploration for the Artemis Generation.” While enroute to the Moon, NASA instruments will measure the quantity of cryogenic engine fuel as it is used, and during descent toward the lunar surface, they will collect data on plume-surface interactions and test precision landing technologies. Once on the Moon, NASA instruments will focus on investigating space weather/lunar surface interactions and radio astronomy. The Nova-C lander also will carry retroreflectors contributing to a network of location markers on the Moon for communication and navigation for future autonomous navigation technologies. NASA science aboard the lander includes: Lunar Node 1 Navigation Demonstrator: A small, CubeSat-sized experiment that will demonstrate autonomous navigation that could be used by future landers, surface infrastructure, and astronauts, digitally confirming their positions on the Moon relative to other spacecraft, ground stations, or rovers on the move. Laser Retroreflector Array: A collection of eight retroreflectors that enable precision laser ranging, which is a measurement of the distance between the orbiting or landing spacecraft to the reflector on the lander. The array is a passive optical instrument and will function as a permanent location marker on the Moon for decades to come. Navigation Doppler Lidar for Precise Velocity and Range Sensing: A Lidar-based (Light Detection and Ranging) guidance system for descent and landing. This instrument operates on the same principles of radar but uses pulses from a laser emitted through three optical telescopes. It will measure speed, direction, and altitude with high precision during descent and touchdown. Radio Frequency Mass Gauge: A technology demonstration that measures the amount of propellant in spacecraft tanks in a low-gravity space environment. Using sensor technology, the gauge will measure the amount of cryogenic propellant in Nova-C’s fuel and oxidizer tanks, providing data that could help predict fuel usage on future missions. Radio-wave Observations at the Lunar Surface of the Photoelectron Sheath: The instrument will observe the Moon’s surface environment in radio frequencies, to determine how natural and human-generated activity near the surface interacts with and could interfere with science conducted there. Stereo Cameras for Lunar Plume-Surface Studies: A suite of four tiny cameras to capture imagery showing how the Moon’s surface changes from interactions with the spacecraft’s engine plume during and after descent. Intuitive Machines’ Nova-C-class lunar lander, named Odysseus, is scheduled to land on the Moon’s South Pole region near the lunar feature known as Malapert A on Thursday, Feb. 22.

4 Min Read Spot the King of Planets: Observe Jupiter NASA’s Juno spacecraft Credits: NASA/JPL-Caltech/SwRI/MSSS/Gerald Eichstadt/Sean Doran Jupiter is our solar system’s undisputed king of the planets! Jupiter is bright and easy to spot from our vantage point on Earth, helped by its massive size and banded, reflective cloud tops. Jupiter even possesses moons the size of planets: Ganymede, its largest, is bigger than the planet Mercury. What’s more, you can easily observe Jupiter and its moons with a modest instrument, just like Galileo did over 400 years ago. Jupiter’s position as our solar system’s largest planet is truly earned; you could fit 11 Earths along Jupiter’s diameter, and in case you were looking to fill up Jupiter with some Earth-size marbles, you would need over 1300 Earths to fill it up – and that would still not be quite enough! However, despite its awesome size, Jupiter’s true rule over the outer solar system comes from its enormous mass. If you took all the planets in our solar system and put them together, they would still only be half as massive as Jupiter all by itself. Jupiter’s mighty mass has shaped the orbits of countless comets and asteroids. Its gravity can fling these tiny objects towards our inner solar system and also draw them into itself, as famously observed in 1994 when Comet Shoemaker-Levy 9, drawn towards Jupiter in previous orbits, smashed into the gas giant’s atmosphere. Its multiple fragments slammed into Jupiter’s cloud tops with such violence that the fireballs and dark impact spots were not only seen by NASA’s orbiting Galileo probe, but also observers back on Earth! Jupiter’s Great Red Spot is close to the size of Earth. Credit: NASA Jupiter is easy to observe at night with our unaided eyes, as well-documented by the ancient astronomers who carefully recorded its slow movements from night to night. It can be one of the brightest objects in our nighttime skies, bested only by the Moon, Venus, and occasionally Mars, when the red planet is at opposition. That’s impressive for a planet that, at its closest to Earth, is still over 365 million miles (587 million km) away. It’s even more impressive that the giant world remains very bright to Earthbound observers at its furthest distance: 600 million miles (968 million km)! While the King of Planets has a coterie of 95 known moons, only the four large moons that Galileo originally observed in 1610 – Io, Europa, Ganymede, and Calisto – can be easily observed by Earth-based observers with very modest equipment. These are called, appropriately enough, the Galilean moons. Most telescopes will show the moons as faint star-like objects neatly lined up close to bright Jupiter. Most binoculars will show at least one or two moons orbiting the planet. Small telescopes will show all four of the Galilean moons if they are all visible, but sometimes they can pass behind or in front of Jupiter, or even each other. Telescopes will also show details like Jupiter’s cloud bands and, if powerful enough, large storms like its famous Great Red Spot, and the shadows of the Galilean moons passing between the Sun and Jupiter. Sketching the positions of Jupiter’s moons during the course of an evening – and night to night – can be a rewarding project!

Juno entered Jupiter’s orbit in 2016 to begin its initial mission to study this giant world’s mysterious interior. The years have proven Juno’s mission a success, with data from the probe revolutionizing our understanding of this gassy world’s guts. Juno’s mission has since been extended to include the study of its large moons, and since 2021 the plucky probe, increasingly battered by Jupiter’s powerful radiation belts, has made close flybys of the icy moons Ganymede and Europa, along with volcanic Io. In Fall 2024 NASA will launch the Europa Clipper mission to study this world and its potential to host life inside its deep subsurface oceans in much more detail.

21 Min Read The Marshall Star for February 14, 2024 Marshall Chief Scientist Provides Valuable Insight into NASA Moonquake Study By Jonathan Deal The Moon holds clues to the evolution of Earth, the planets, and the Sun, and a new NASA-funded study is helping scientists better understand some of the mysteries beneath the surface of our nearest cosmic neighbor. The co-author of that study is chief scientist of NASA’s Marshall Space Flight Center, Renee Weber, who is also a member of NASA’s Artemis Science Team – a broad group of scientists from around the agency working to commence a new era of deep space science and exploration. As a lunar seismologist and lunar geophysicist, Weber provides expertise to the Artemis Science Team, including knowledge of the types of seismic events that can occur on the Moon, to better understand its internal geology and surface environment. The epicenter of one of the strongest moonquakes recorded by the Apollo Passive Seismic Experiment was in the lunar south polar region. However, the exact location of the epicenter could not be accurately determined. A cloud of possible locations (magenta dots and light blue polygon) of the strong shallow moonquake using a relocation algorithm specifically adapted for very sparse seismic networks are distributed near the pole. Blue boxes show locations of proposed Artemis III landing regions. Lobate thrust fault scarps are shown by small red lines. The cloud of epicenter locations encompasses a number of lobate scarps and many of the Artemis III landing regions.NASA/LROC/ASU/Smithsonian Institution The latest study revealed that the Moon is still geologically active and presents evidence that tectonic faults, generated as the Moon’s interior gradually cools and shrinks, are found near some of the areas NASA identified as candidate landing regions for Artemis III – the first Artemis mission planned to have a crewed lunar landing. “This study looked at tectonic faults and steep slopes in the lunar South polar region and found that some areas are susceptible to seismic shaking and regolith landslides,” Weber said. “Once the faults were mapped, we calculated the sizes of potential moonquakes that could be generated to create a map of seismic hazard in the vicinity of tectonic faults and steep slopes.” The study discovered that relatively small, young thrust faults, called lobate scarps, are widely distributed in the lunar crust. The scarps form where contractional forces break the crust and push, or thrust, rock on one side of the fault up and over rock on the other side. The contraction is caused by cooling of the Moon’s still-hot interior and tidal forces exerted by Earth, resulting in global shrinking. The scarps were identified in images taken by the Lunar Reconnaissance Orbiter Camera onboard NASA’s LRO (Lunar Reconnaissance Orbiter). The formation of the faults is accompanied by seismic activity in the form of shallow-depth moonquakes. Such shallow moonquakes were recorded by the Apollo Passive Seismic Network, a series of seismometers deployed by the Apollo astronauts, and could potentially also be recorded by a new seismic instrument scheduled to launch next year aboard an upcoming CLPS (Commercial Lunar Payload Services) flight. That instrument – the Farside Seismic Suite – will return the agency’s first seismic data from the far side of the Moon, helping scientists to understand the region’s tectonic activity. The data may also reveal how often the lunar far side is impacted by small meteorites and determine if the seismicity is different on the far side of the Moon from what was measured during Apollo on the lunar near side. “To better understand the seismic hazard posed to future human activities on the Moon, we need new seismic data, not just at the South Pole, but globally,” Weber said. “Missions like the upcoming Farside Seismic Suite, as well as future potential missions like the Lunar Geophysical Network concept, will expand upon measurements made during Apollo and add to our knowledge of global seismicity.” Renee Weber is chief scientist at NASA’s Marshall Space Flight Center.NASA As NASA develops long-term infrastructure on the lunar surface, Weber’s research will provide invaluable insight for the Artemis Science Team that will be refining mission architectures that preserve flexibility for science and operations at a variety of landing sites and will apply new scientific knowledge, such as continued research on seismic measurements, gathered along the way. “Being able to go back to the Moon, gather more data, and pick up more samples will help us improve our understanding of the Moon and answer our fundamental questions – how did it form? How did it evolve? Where are the resources? More seismic measurements like the ones conducted during Apollo could help us better characterize seismicity in the lunar South Pole region,” Weber said. The study does not impact the Artemis III landing region selection process, according to Weber, because estimating how often a specific region experiences a moonquake is difficult to do accurately, and like earthquakes, scientists can’t predict moonquakes. Additionally, for a shorter duration mission like Artemis III, the likelihood of experiencing hazards due to seismic shaking is much lower. As NASA develops long-term infrastructure, the agency will identify potential regions for where different elements can be established closer to the dates of future Artemis missions. In this site selection process, some of the factors for consideration could be geographic characteristics such as proximity to tectonic features and terrain, making Weber’s research all the more valuable.

Today, Johnson and a NASA team are preparing to test a similar technology. NASA continues to unfurl plans for solar sail technology as a promising method of deep space transportation. The agency cleared a key technology milestone in January with the successful deployment of one of four identical solar sail quadrants. The deployment was showcased Jan. 30 at Redwire Corp.’s new facility in Longmont, Colorado. NASA’s Marshall Space Flight Center leads the solar sail team, comprised of prime contractor Redwire, which developed the deployment mechanisms and the nearly 100-foot-long booms, and subcontractor NeXolve, of Huntsville, which provided the sail membrane. In addition to leading the project, Marshall developed the algorithms needed to control and navigate with the sail when it flies in space. NASA and industry partners used two 100-foot lightweight composite booms to unfurl the 4,300-square-foot sail quadrant for the first time Oct. 13, 2022, at Marshall Space Flight Center, making it the largest solar sail quadrant ever deployed at the time. On Jan. 30, 2024, NASA cleared a key technology milestone at Redwire’s new facility in Longmont, Colorado, with the successful deployment of one of four identical solar sail quadrants.NASA The sail is a propulsion system powered by sunlight reflecting from the sail, much like a sailboat reflects the wind. While just one quarter of the sail was unfurled in the deployment at Redwire, the complete sail will measure 17,780 square feet when fully deployed, with the thickness less than a human hair at 2 and a half microns. The sail is made of a polymer material coated with aluminum. NASA’s Science Mission Directorate recently funded the solar sail technology to reach a new technology readiness level, or TRL 6, which means it’s ready for proposals to be flown on science missions. “This was a major last step on the ground before it’s ready to be proposed for space missions,” Johnson, who has been involved with sail technology at Marshall for about 25 years, said. “What’s next is for scientists to propose the use of solar sails in their missions. We’ve met our goal and demonstrated that we’re ready to be flown.” A solar sail traveling through deep space provides many potential benefits to missions using the technology because it doesn’t require any fuel, allowing very high propulsive performance with very little mass. This in-space propulsion system is well suited for low-mass missions in novel orbits. “Once you get away from Earth’s gravity and into space, what is important is efficiency and enough thrust to travel from one position to another,” Johnson said. Some of the missions of interest using solar sail technology include studying space weather and its effects on the Earth, or for advanced studies of the north and south poles of the Sun. The latter has been limited because the propulsion needed to get a spacecraft into a polar orbit around the Sun is very high and simply not feasible using most of the propulsion systems available today. Solar sail propulsion is also possible for enhancing future missions to Venus or Mercury, given their closeness to the Sun and the enhanced thrust a solar sail would achieve in the more intense sunlight there. Moreover, it’s the ultimate green propulsion system, Johnson said – as long as the Sun is shining, the sail will have propulsion. Where the sunlight is less, he envisions a future where lasers could be used to accelerate the solar sails to high speeds, pushing them outside the solar system and beyond, perhaps even to another star. “In the future, we might place big lasers in space that shine their beams on the sails as they depart the solar system, accelerating them to higher and higher speeds, until eventually they are going fast enough to reach another star in a reasonable amount of time.” Learn more about solar sails and other NASA advanced space technology.

Liftoff will be from Launch Complex 39A at the agency’s Kennedy Space Center. The launch of the mission was postponed Feb. 13 due to off-nominal methane temperatures prior to stepping into methane load. The Nova-C lunar lander is encapsulated within the fairing of a SpaceX Falcon 9 rocket in preparation for launch as part of NASA’s CLPS (Commercial Lunar Payload Services) initiative and Artemis campaign.SpaceX Live launch coverage will air on NASA+, NASA Television, the NASA app, and the agency’s website. NASA TV launch coverage begins at 11:20 p.m. Coverage is subject to change based on real-time operational activities. Follow the Artemis blog for updates. Intuitive Machines’ Nova-C lander is expected to land on the Moon on Feb. 22. Among the items on its lander, the IM-1 mission will carry NASA science and technology instruments focusing on plume-surface interactions, space weather/lunar surface interactions, radio astronomy, precision landing technologies, and a communication and navigation node for future autonomous navigation technologies. Demonstrating autonomous navigation, the Lunar Node-1 experiment, or LN-1, is a radio beacon designed to support precise geolocation and navigation observations for landers, surface infrastructure, and astronauts, digitally confirming their positions on the Moon relative to other craft, ground stations, or rovers on the move. LN-1 was developed, built, and tested at NASA’s Marshall Space Flight Center. › Back to Top Telescopes Show the Milky Way’s Black Hole is Ready for a Kick An artist’s illustration depicts the findings of a new study about the supermassive black hole at the center of our galaxy called Sagittarius A* (abbreviated as Sgr A*). As reported in a press release, this result found that Sgr A* is spinning so quickly that it is warping spacetime – that is, time and the three dimensions of space – so that it can look more like a football. These results were made with NASA’s Chandra X-ray Observatory and the National Science Foundation’s Karl G. Jansky Very Large Array, or VLA. A team of researchers applied a new method that uses X-ray and radio data to determine how quickly Sgr A* is spinning based on how material is flowing towards and away from the black hole. They found Sgr A* is spinning with an angular velocity that is about 60% of the maximum possible value, and with an angular momentum of about 90% of the maximum possible value. This artist’s illustration depicts the findings of a new study about the supermassive black hole at the center of our galaxy called Sagittarius A* (abbreviated as Sgr A*). This result found that Sgr A* is spinning so quickly that it is warping spacetime – that is, time and the three dimensions of space – so that it can look more like a football.NASA/CXC/M.Weiss Black holes have two fundamental properties: their mass (how much they weigh) and their spin (how quickly they rotate). Determining either of these two values tells scientists a great deal about any black hole and how it behaves. In the past, astronomers made several other estimates of Sgr A*’s rotation speed using different techniques, with results ranging from Sgr A* not spinning at all to it spinning at almost the maximum rate. The new study suggests that Sgr A* is, in fact, spinning very rapidly, which causes the spacetime around it to be squashed down. The illustration shows a cross-section of Sgr A* and material swirling around it in a disk. The black sphere in the center represents the so-called event horizon of the black hole, the point of no return from which nothing, not even light, can escape. Looking at the spinning black hole from the side, as depicted in this illustration, the surrounding spacetime is shaped like a football. The faster the spin the flatter the football. The yellow-orange material to either side represents gas swirling around Sgr A*. This material inevitably plunges towards the black hole and crosses the event horizon once it falls inside the football shape. The area inside the football shape but outside the event horizon is therefore depicted as a cavity. The blue blobs show jets firing away from the poles of the spinning black hole. Looking down on the black hole from the top, along the barrel of the jet, spacetime is a circular shape. Chandra X-ray image of Sagittarius A* and the surrounding region.NASA/CXC/Univ. of Wisconsin/Y.Bai, et al. A black hole’s spin can act as an important source of energy. Spinning supermassive black holes produce collimated outflows such as jets when their spin energy is extracted, which requires that there is at least some matter in the vicinity of the black hole. Because of limited fuel around Sgr A*, this black hole has been relatively quiet in recent millennia with relatively weak jets. This work, however, shows that this could change if the amount of material in the vicinity of Sgr A* increases. To determine the spin of Sgr A*, the authors used an empirically based technique referred to as the “outflow method” that details the relationship between the spin of the black hole and its mass, the properties of the matter near the black hole, and the outflow properties. The collimated outflow produces the radio waves, while the disk of gas surrounding the black hole is responsible for the X-ray emission. Using this method, the researchers combined data from Chandra and the VLA with an independent estimate of the black hole’s mass from other telescopes to constrain the black hole’s spin. The paper describing these results led by Ruth Daly (Penn State University) is published in the January 2024 issue of the Monthly Notices of the Royal Astronomical Society and appears online. The other authors are Biny Sebastian (University of Manitoba, Canada), Megan Donahue (Michigan State University), Christopher O’Dea (University of Manitoba), Daryl Haggard (McGill University) and Anan Lu (McGill University).

Dyson will help support aboard the International Space Station as part of Expedition 71. NASA’s SpaceX Crew-8 mission is targeting launch to the space station later this month. A flag for Crew-8 will be raised Feb. 26 outside the HOSC (Huntsville Operation Support Center) at NASA’s Marshall Space Flight Center. The HOSC is a multi-mission facility that provides engineering and mission operations support for NASA’s Commercial Crew Program, Space Launch System rocket, Artemis lunar science missions, and science conducted on the space station. Brain organoid cells from the previous investigation Cosmic Brain Organoids are made of cells from people with Parkinson’s Disease and primary progressive multiple sclerosis. The sixth space station organoid investigation funded by the National Stem Cell Foundation, HBOND, includes for the first time Alzheimer’s iPSCs and testing of the effects of drugs in development to treat neuroinflammation.New York Stem Cell Research Institute The Payload Operations Integration Center within HOSC operates, plans, and coordinates the science experiments onboard the space station 365 days a year, 24 hours a day. Here are details on some of the work scheduled during this upcoming expedition aboard the microgravity laboratory: Modeling Neuroinflammation HBOND (Human Brain Organoid Models for Neurodegenerative Disease & Drug Discovery) studies the mechanisms behind neuroinflammation, a common feature of neurodegenerative disorders. Researchers create organoids using patient-derived iPSCs (induced pluripotent stem cells) from patients who have Parkinson’s disease and primary progressive multiple sclerosis. The sixth space station organoid investigation funded by the National Stem Cell Foundation, HBOND includes for the first time Alzheimer’s iPSCs and testing of the effects of drugs in development to treat neuroinflammation. Results could help improve diagnostics, provide insights into the effects of aging, accelerate drug discovery, and identify therapeutic targets for patients suffering from neurodegenerative diseases. The organoid models also could provide a way to anticipate how extended spaceflight affects the brain and support development of countermeasures. Protecting Plants from Spaceflight Stressors Plants can serve as a source of food and provide other life-support services on long-term missions to the Moon and Mars. The Study on Plant Responses Against the Stresses of Microgravity and High Ultraviolet Radiation in Space (Plant UV-B) examines how stress from microgravity, UV radiation, and the combination of the two affect plants at the molecular, cellular, and whole organism levels. Results could increase understanding of plant growth in space and support improvements in plant cultivation technologies for future missions. This image shows the Plant Experiment Unit (PEU) hardware for the Plant UV-B investigation.NASA Reversing Fluid Shifts Weightlessness causes fluids in the body to move toward the head, which can cause changes in eye structure and vision known as Spaceflight Associated Neuro-ocular Syndrome (SANS) along with other health problems. Mitigating Headward Fluid Shifts with Veno-constrictive Thigh Cuffs During Spaceflight (Thigh Cuff) examines whether thigh pressure cuffs could provide a simple way to counter this shift in body fluids and help protect astronauts from SANS and other issues on future missions to the Moon and Mars. Thigh cuffs also could help treat or prevent problems for patients on Earth who have conditions that cause fluid accumulation in the head, such as long-term bedrest and diseases. Incredible Edible Algae Arthrospira-C (Art-C), an investigation from ESA (European Space Agency) analyzes how the cyanobacterium Limnospira responds to spaceflight conditions and whether it produces the same quantity and quality of oxygen and biomass in space as on Earth. These microalgae, also known as Spirulina, could be used to remove carbon dioxide exhaled by astronauts, which can become toxic in an enclosed spacecraft, and to produce oxygen and fresh food as part of life support systems on future missions. Correct predictions of oxygen and biomass yields are crucial for design of life support systems using bioprocesses. Spirulina also has been shown to have radioprotective properties and eating it could help protect space travelers from cosmic radiation, as well as conserve healthy tissue in patients undergoing radiation treatment on Earth.

3 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) A sample of fabric burns inside an uncrewed Cygnus cargo craft during a previous Spacecraft Fire Safety Experiment investigation, Saffire-IV.Credit: NASA NASA recently concluded the final mission of its Spacecraft Fire Safety Experiment, or Saffire, putting a blazing end to an eight-year series of investigations that provided insights into fire’s behavior in space. The final experiment, Saffire-VI, launched to the International Space Station in August 2023 and concluded its mission on Jan. 9, when the Northrop Grumman Cygnus spacecraft it was flying on safely burned up during planned re-entry into Earth’s atmosphere. Dr. David Urban, principal investigator, and Dr. Gary Ruff, project manager at NASA’s Glenn Research Center in Cleveland, have led the Saffire project from Northeast Ohio since its initial spark in 2016. Throughout the experiment series, researchers gathered data NASA will use to enhance mission safety and inform future spacecraft and spacesuit designs. “How big a fire does it take for things to get bad for a crew?” Urban said. “This kind of work is done for every other inhabited structure here on Earth – buildings, planes, trains, automobiles, mines, submarines, ships – but we hadn’t done this research for spacecraft until Saffire.” Like previous Saffire experiments, Saffire-VI took place inside a unit on an uninhabited Cygnus spacecraft that had already departed from the space station, ensuring the safety of the orbiting laboratory and a more representative flight environment. However, this final iteration of the experiment was unique because of the higher oxygen concentration and lower pressure generated in the test unit to simulate the conditions within crewed spacecraft. To view this video please enable JavaScript, and consider upgrading to a web browser that supports HTML5 video NASA ignited the final set of space fire experiments for Saffire-VI inside Northrop Grumman’s Cygnus cargo spacecraft at the end of the NG-19 resupply mission to the International Space Station. Saffire, or Spacecraft Fire Safety Experiment, was a series of six investigations that provided insights into how fires grow and spread in space. This research is especially important as it will inform future spacecraft designs bound for the Moon and Mars. Video credit: NASA During the 19 Saffire-VI experiment runs, the NASA team and counterparts at Northrop Grumman made various adjustments to air conditions. They then ignited a flame on materials such as plexiglass, cotton, Nomex, and Solid Inflammability Boundary at Low-Speed fabrics. A bead-lined wire inside the unit ignited the materials. “The Saffire flow unit is a wind tunnel. We’re pushing air through it,” Ruff said. “Once test conditions are set, we run electrical current through a thin wire, and the materials ignite.” Cameras inside allowed the team to observe the flame while remote sensors outside the Saffire flow unit collected data about what was happening in the Cygnus vehicle. The images and information were gathered in real-time before being sent to Earth for scientists to analyze. “You’ve got a heat release rate and a rate of release of combustion products,” Ruff said. “You can take those as model input and predict what will happen in a vehicle.” The next decade of exploration and science missions will see astronauts flying deeper into space and to locations that have yet to be explored. Though the Saffire experiments have been extinguished, NASA has learned valuable lessons and gathered mountains of data on fire behavior that will help the agency design safer spacecraft and accomplish its ambitious future missions.

NASA/Ben Smegelsky A NASA photographer captured the sunset on Tuesday, Jan. 30, 2024, near the Vehicle Assembly Building (VAB) at the agency’s Kennedy Space Center in Florida. The iconic building, completed in 1966 and currently used for assembly of NASA’s Space Launch System rocket for Artemis missions, is still the only building in which rockets were assembled that carried humans to the surface of another world. The VAB stands 525 feet tall and contains 130 million cubic feet of interior space. It sports a large American flag – a 209-foot-tall, 110-foot-wide stars and stripes painted on the exterior of its south side. Each star measures six feet across, and the blue field is the size of a basketball court. The flag originally was painted onto the VAB in 1976 for the Bicentennial Exposition on Space and Technology. A 12,300-square-foot NASA logo also adorns the south side of the facility. The VAB has received a number of distinctions. It was listed in the National Register of Historic Places on Jan. 21, 2000. In January 2020, the American Society of Civil Engineers designated the VAB as a National Historic Civil Engineering Landmark. The Florida Association of The American Institute of Architects honored the facility and its adjacent Launch Control Center with a “Test of Time” design award, recognizing the contributions of the architects and engineers of these unique buildings.
