Bruce Askins Growing up, Bruce Askins was passionate about space and oceanography. His desire to explore other worlds always made him want to be an astronaut. Though he did not become an astronaut, Askins has built a 42-year career at NASA, and, as the infrastructure management lead for NASA’s SLS (Space Launch System) Program at the agency’s Marshall Space Flight Center in Huntsville, Alabama, Askins is an integral part for the next generation of explorers. Askins and his team are the gatekeepers and protectors of data and responsible for both cyber- security and physical security for the SLS Program. Under Askins’ leadership, his team ensures all data is stored properly, that information about the rocket shared outside NASA is done with proper data markings, and access is given to those that need it. Askins wasn’t always familiar with the world of infrastructure and cyber security. As a mechanical engineering graduate from the University of Alabama in Huntsville, Askins began his career as part of NASA’s internship program. He considered himself imaginative, or “creatively driven,” which is why Askins originally pursued a career at NASA. “I always loved the design aspect of my early position in special test equipment,” Askins says. “Back then I drew everything by hand with a pencil before eventually transitioning to computers.” His creativity and interest in underwater worlds, along with his scuba diver certification, led him to have a hand in designing early test elements for NASA’s Hubble Space Telescope. At the Neutral Buoyancy Simulator, a former underwater training facility at Marshall, Askins interacted with a crew of astronauts supporting Hubble and designed the flight simulation hardware used for crew training on the Canadarm2 robotic arm that is still a part of the International Space Station today. Askins has been a part of the NASA family for almost half a century and is thrilled to be a part of the next era of space exploration to the Moon under Artemis. “To explore is one of the greatest things that we can all do, and with the Artemis Generation the sky’s the limit,” Askins said. SLS is part of NASA’s backbone for deep space exploration, along with the Orion spacecraft, advanced spacesuits and rovers, the Gateway in orbit around the Moon, and commercial human landing systems. SLS is the only rocket that can send Orion, astronauts, and supplies to the Moon in a single launch. Check out some of our other “I am Artemis” features. View the full article

3 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) Crews at NASA’s Stennis Space Center cleared a milestone Dec. 11, installing a key component in preparation for future Green Run testing of NASA’s new Exploration Upper Stage (EUS) vehicle for use on the SLS (Space Launch System) rocket. Four large diffusers, each weighing 14 tons, were lifted by crane for installation on the Thad Cochran Test Stand (B-2). The diffusers are a critical component designed to help direct engine exhaust away from the EUS during hot fire testing to minimize heat exposure to sensitive vehicle systems. NASA Stennis teams lift and install large diffusers onto the Thad Cochran Test Stand (B-2).NASA/Danny Nowlin NASA Stennis teams lift and install large diffusers onto the Thad Cochran Test Stand (B-2).NASA/Danny Nowlin NASA Stennis teams lift and install large diffusers onto the Thad Cochran Test Stand (B-2).NASA/Danny Nowlin NASA Stennis teams lift and install large diffusers onto the Thad Cochran Test Stand (B-2).NASA/Danny Nowlin NASA Stennis teams lift and install large diffusers onto the Thad Cochran Test Stand (B-2).NASA/Danny Nowlin NASA Stennis teams lift and install large diffusers onto the Thad Cochran Test Stand (B-2).NASA/Danny Nowlin NASA Stennis teams lift and install large diffusers onto the Thad Cochran Test Stand (B-2).NASA/Danny Nowlin NASA Stennis teams lift and install large diffusers onto the Thad Cochran Test Stand (B-2).NASA/Danny Nowlin NASA Stennis teams lift and install large diffusers onto the Thad Cochran Test Stand (B-2).NASA/Danny Nowlin NASA Stennis teams lift and install large diffusers onto the Thad Cochran Test Stand (B-2).NASA/Danny Nowlin NASA Stennis teams lift and install large diffusers onto the Thad Cochran Test Stand (B-2).NASA/Danny Nowlin NASA Stennis teams lift and install large diffusers onto the Thad Cochran Test Stand (B-2).NASA/Danny Nowlin NASA’s new EUS is being built at NASA’s Michoud Assembly Facility in New Orleans as a more powerful SLS second stage to send the Orion spacecraft and heavier payloads to deep space as NASA continues its mission to explore the secrets of the universe for the benefit of all. The EUS is expected to fly on the Artemis IV mission following a series of Green Run tests of its integrated systems at NASA Stennis to demonstrate it is ready to fly. The test series will culminate with a hot fire of the four RL10 engines that will power the EUS. NASA Stennis teams lifted and installed large diffusers onto the Thad Cochran Test Stand (B-2) on December 11, 2023, in preparation for future Green Run testing of the new Exploration Upper Stage before it flies on the SLS (Space Launch System) rocket as part of NASA’s Artemis missions to the Moon and beyond. During an actual flight, critical EUS systems will be protected by the SLS interstage. To protect the systems during Green Run testing, teams are using an interstage simulator, a size-and-weight replica of the actual SLS interstage, and the connected diffusers. The system requires a high level of precision. The diffusers will be connected to the EUS engine nozzles using a flexible seal so gimbaling, or moving a rocket engine a few degrees along a tight circular axis to direct the thrust and “steer” the vehicle, can occur during testing. They also are designed to facilitate propellant connections and allow test teams access to the engine area as needed. The carbon steel diffusers were precisely designed by a joint NASA Stennis and Jacobs Engineering team, using computational models, subscale testing, and historical data. The units then were made by Custom Steel Fabricators in Columbia, Tennessee, and delivered by truck to NASA Stennis. Following lift and installation on the test stand, the diffuser system will be connected to the facility water and hydraulic supplies. A final checkout of the system will include a full test stand water flow demonstration. Share Details Last Updated Dec 13, 2023 EditorNASA Stennis CommunicationsContactC.

It’s been another great year at NASA’s Ames Research Center in California’s Silicon Valley. Join us as we review some of the highlights of the science, engineering, and innovation from 2023. Announcing a New Innovation Hub Planned for NASA Research Park at Ames NASA Berkeley Space Center is a proposed new campus of the University of California, Berkeley, and an innovation hub for research and advances in astronautics, aeronautics, quantum computing, climate studies, and more. Planning to join Ames as a tenant of our NASA Research Park in Silicon Valley, the new campus aims to bring together researchers from the private sector, academia, and the government to tackle the complex scientific, technological, and societal issues facing our world. Mapping Water Distribution on the Moon’s South Pole NASA Using data collected by the now-retired Stratospheric Observatory for Infrared Astronomy (SOFIA), researchers shared the first detailed, wide-area map of water distribution on the Moon. Understanding how much water lies beneath the lunar surface, and how it’s distributed, will help guide future missions like VIPER, as well as prospective sites for human habitats. Colliding Moons May Have Formed Saturn’s Rings NASA New research suggests Saturn’s icy moons and rings were formed by a collision a few hundred million years ago, creating debris that gathered into the planet’s dusty, icy rings or clumped together to form moons. NASA and Airlines Partner to Save Fuel and Reduce Delays NASA/James Blair This year, NASA partnered with five major U.S. airlines on an air traffic decision-making tool that saved more than 24,000 pounds of jet fuel in 2022 for flights departing from Dallas-Fort Worth International Airport and Dallas Love Field Airport. Partners include American Airlines, Delta Air Lines, JetBlue Airways, Southwest Airlines and United Airlines. NASA Leaders View Climate Science, Wildfire Innovations at Ames NASA/Dominic Hart NASA’s top leadership, industry experts, and legislative officials visited Ames in April to learn about about the center’s climate science efforts and innovations in aeronautics that will help scientists and engineers better understand climate change and mitigate natural disasters like wildland fires.

You can track mission milestones via the Small Satellite Missions blog, and follow the mission live in NASA’s Eyes on the Solar System 3D visualization. NASA’s First Robotic Moon Rover NASA/Robert Markowitz This year engineers began assembling NASA’s first robotic Moon rover, VIPER — short for the Volatiles Investigating Polar Exploration Rover — and the agency is giving the public a front row seat to watch along as the rover takes shape. While individual components, such as the rover’s science instruments, lights, and wheels, were assembled and tested, the VIPER team also completed software development, mission planning, and tricky tests of the rover’s ability to drive off the Astrobotic Griffin lunar lander and onto the lunar surface. Bringing Home Ancient Space Rocks NASA/Keegan Barber NASA’s OSIRIS-REx mission – short for the Origins, Spectral Interpretation, Resource Identification, and Security-Regolith Explorer – returned to Earth in Sept. 2023, bringing with it extraterrestrial rocks and dust that it scooped up from an asteroid estimated to be 4.5 billion years old. Ames contributed to the spacecraft’s heat shield, anti-contamination systems, post-landing sample curation, and more. Preparing to Send Yeast to the Moon’s Surface for Astronaut Health NASA/Dominic Hart NASA’s plans to explore the Moon and eventually go to Mars will bring humans deeper into space for longer duration missions than ever before. These extended missions beyond low Earth orbit pose certain health risks to astronauts. The Lunar Explorer Instrument for Space Biology Applications team is preparing an experiment to study yeast’s biological response to the lunar environment to help understand and mitigate health risks for astronauts. X-59 Team Moves Toward First Flight in 2024 Lockheed Martin/Gary Tice This year, NASA’s X-59 team installed the finishing touches to the aircraft’s tail structure and moved it from its assembly facility to the flight line to perform structural testing. The X-59 quiet supersonic aircraft will take its first flight in 2024. Celebrating a Stellar Year for Webb Telescope Science NASA, ESA, CSA, STScI, and S. Crowe (University of Virginia) The James Webb Space Telescope’s Near-Infrared Camera instrument produced a feast for the eyes with a view into a star-forming region, named Sagittarius C, in the heart of the Milky Way. The image reveals a portion of the dense center of our galaxy in unprecedented detail, including never-before-seen features astronomers have yet to explain. Supercomputer Simulations Lead to Air and Space Innovations NASA Simulations and models developed using technology at the NASA Advanced Supercomputing Facility (NAS) help researchers and engineers develop innovations in air and space. Modeling turbofan engines could lead to designs that reduce engine noise and improve efficiency by understanding where noise is generated inside the machine. S-MODE Sails the Seas and Soars through the Sky NASA/Avery Snyder The Sub-Mesoscale Ocean Dynamics Experiment (S-MODE) logged its final field expedition, and they took a team from the TODAY Show along for the ride. S-MODE combined airborne instruments, research ships, and autonomous ocean gliders to get an unprecedented look at how gas and heat exchange at the ocean’s surface impacts Earth’s climate. From Intern to Astronaut, and Back to Ames NASA/Dominic Hart NASA astronaut Jessica Watkins, who was once an intern at Ames, returned to the Bay Area in Feb. 2023 to visit with local elementary schools and speak with Ames employees. Watkins started her career with NASA at Ames, where she conducted research on Mars soil simulant supporting the Phoenix Mars Lander mission.

3 Min Read NASA’s Space Station Laser Comm Terminal Achieves First Link NASA’s ILLUMA-T payload at Goddard Space Flight Center fully tested and integrated prior to its delivery to Kennedy Space Center. Credits: NASA's Goddard Space Flight Center A NASA technology experiment on the International Space Station completed its first laser link with an in-orbit laser relay system on Dec. 5, 2023. Together, they complete NASA’s first two-way, end-to-end laser relay system. NASA’s LCRD (Laser Communications Relay Demonstration) and the new space station demonstration, ILLUMA-T (Integrated LCRD Low Earth Orbit User Modem and Amplifier Terminal), successfully exchanged data for the first time. LCRD and ILLUMA-T are demonstrating how a user mission, in this case the space station, can benefit from a laser communications relay located in geosynchronous orbit. NASA’s ILLUMA-T payload communicating with LCRD over laser signals.NASA / Dave Ryan Laser communications, also known known as optical communications, uses infrared light rather than traditional radio waves to send and receive signals. The tighter wavelength of infrared light allows spacecraft to pack more data into each transmission. Using laser communications greatly increases the efficiency of data transfer and can lead to a faster pace of scientific discoveries. The benefits of laser communications: more efficient, lighter systems, increased security, and more flexible ground systems.NASA / Dave Ryan On Nov. 9, NASA’s SpaceX 29th commercial resupply services mission launched cargo and new science experiments, including ILLUMA-T, to the space station. Following its arrival, the payload was installed onto the station’s Japanese Experiment Module-Exposed Facility. The SpaceX Falcon 9 rocket carrying the Dragon spacecraft lifts off from Launch Complex 39A at NASA’s Kennedy Space Center in Florida on Thursday, Nov. 9, 2023, on the company’s 29th commercial resupply services mission for the agency to the International Space Station. Liftoff was at 8:28 p.m. EST. SpaceX ILLUMA-T and LCRD are a part of the NASA Space Communications and Navigation (SCaN) program’s effort to demonstrate how laser communications technologies can significantly benefit science and exploration missions. “ILLUMA-T’s first link with LCRD – known as first light – is the latest demonstration proving that laser communications is the future.” said Dr. Jason Mitchell, director of SCaN’s Advanced Communications and Navigation Technology division. “Laser communications will not only return more data from science missions, but could serve as NASA’s critical, two-way link to keep astronauts connected to Earth as they explore the Moon, Mars, and beyond.” To view this video please enable JavaScript, and consider upgrading to a web browser that supports HTML5 video NASA's ILLUMA-T payload achieved First Light with LCRD. In this video, Matt Magsamen explains the First Light milestone. Shortly after space station installation, operation engineers began conducting on-orbit testing to ensure the ILLUMA-T payload operated nominally. Now, it is communicating with LCRD, a relay launched in 2021 that has conducted over 300 experiment configurations to help NASA refine laser communications technologies. LCRD and ILLUMA-T are exchanging data at 1.2 gigabits-per-second. “We have demonstrated that we can overcome the technical challenges for successful space communications using laser communications. We are now performing operational demonstrations and experiments that will allow us to optimize our infusion of proven technology into our missions to maximize our exploration and science,” said David Israel, a NASA space communications and navigation architect. NASA’s Laser Communications Roadmap: Demonstrating laser communications capabilities on multiple missions in a variety of space regimes.NASA/Dave Ryan The LCRD experiments are conducted with industry, academia, and other government agencies.

6 Min Read NASA’s Webb Identifies Tiniest Free-Floating Brown Dwarf Webb Telescope's Near-Infrared Camera shows the central portion of the star cluster IC 348. Credits: NASA, ESA, CSA, STScI, K. Luhman (Penn State University), and C. Alves de Oliveira (ESA) Brown dwarfs are objects that straddle the dividing line between stars and planets. They form like stars, growing dense enough to collapse under their own gravity, but they never become dense and hot enough to begin fusing hydrogen and turn into a star. At the low end of the scale, some brown dwarfs are comparable with giant planets, weighing just a few times the mass of Jupiter. What are the smallest stars? Astronomers are trying to determine the smallest object that can form in a star-like manner. A team using NASA’s James Webb Space Telescope has identified the new record-holder: a tiny, free-floating brown dwarf with only three to four times the mass of Jupiter. “One basic question you’ll find in every astronomy textbook is, what are the smallest stars? That’s what we’re trying to answer,” explained lead author Kevin Luhman of Pennsylvania State University. Search Strategy To locate this newfound brown dwarf, Luhman and his colleague, Catarina Alves de Oliveira, chose to study the star cluster IC 348, located about 1,000 light-years away in the Perseus star-forming region. This cluster is young, only about 5 million years old. As a result, any brown dwarfs would still be relatively bright in infrared light, glowing from the heat of their formation. The team first imaged the center of the cluster using Webb’s NIRCam (Near-Infrared Camera) to identify brown dwarf candidates from their brightness and colors. They followed up on the most promising targets using Webb’s NIRSpec (Near-Infrared Spectrograph) microshutter array. Image: Star Cluster IC438 This image from the NIRCam (Near-Infrared Camera) instrument on NASA’s James Webb Space Telescope shows the central portion of the star cluster IC 348. The wispy curtains filling the image are interstellar material reflecting the light from the cluster’s stars – what is known as a reflection nebula. The material also includes carbon-containing molecules known as polycyclic aromatic hydrocarbons, or PAHs. Winds from the most massive stars in the cluster may help sculpt the large loop seen on the right side of the field of view.NASA, ESA, CSA, STScI, K. Luhman (Penn State University), and C. Alves de Oliveira (ESA) Webb’s infrared sensitivity was crucial, allowing the team to detect fainter objects than ground-based telescopes. In addition, Webb’s sharp vision enabled them to determine which red objects were pinpoint brown dwarfs and which were blobby background galaxies. This winnowing process led to three intriguing targets weighing three to eight Jupiter masses, with surface temperatures ranging from 1,500 to 2,800 degrees Fahrenheit (830 to 1,500 degrees Celsius). The smallest of these weighs just three to four times Jupiter, according to computer models. Explaining how such a small brown dwarf could form is theoretically challenging. A heavy and dense cloud of gas has plenty of gravity to collapse and form a star. However, because of its weaker gravity, it should be more difficult for a small cloud to collapse to form a brown dwarf, and that is especially true for brown dwarfs with the masses of giant planets. “It’s pretty easy for current models to make giant planets in a disk around a star,” said Catarina Alves de Oliveira of ESA (European Space Agency), principal investigator on the observing program. “But in this cluster, it would be unlikely this object formed in a disk, instead forming like a star, and three Jupiter masses is 300 times smaller than our Sun. So we have to ask, how does the star formation process operate at such very, very small masses?” A Mystery Molecule In addition to giving clues about the star-formation process, tiny brown dwarfs also can help astronomers better understand exoplanets. The least massive brown dwarfs overlap with the largest exoplanets; therefore, they would be expected to have some similar properties. However, a free-floating brown dwarf is easier to study than a giant exoplanet since the latter is hidden within the glare of its host star. Two of the brown dwarfs identified in this survey show the spectral signature of an unidentified hydrocarbon, or molecule containing both hydrogen and carbon atoms. The same infrared signature was detected by NASA’s Cassini mission in the atmospheres of Saturn and its moon Titan. It has also been seen in the interstellar medium, or gas between stars. “This is the first time we’ve detected this molecule in the atmosphere of an object outside our solar system,” explained Alves de Oliveira. “Models for brown dwarf atmospheres don’t predict its existence. We’re looking at objects with younger ages and lower masses than we ever have before, and we’re seeing something new and unexpected.” Image: Three Brown Dwarfs This image from the NIRCam (Near-Infrared Camera) instrument on NASA’s James Webb Space Telescope shows the central portion of the star cluster IC 348. Astronomers combed the cluster in search of tiny, free-floating brown dwarfs: objects too small to be stars but larger than most planets. They found three brown dwarfs that are less than eight times the mass of Jupiter, which are circled in the main image and shown in the detailed pullouts at right. The smallest weighs just three to four times Jupiter, challenging theories for star formation.NASA, ESA, CSA, STScI, K. Luhman (Penn State University), and C. Alves de Oliveira (ESA) Brown Dwarf or Rogue Planet? Since the objects are well within the mass range of giant planets, it raises the question of whether they are actually brown dwarfs, or if they’re really rogue planets that were ejected from planetary systems. While the team can’t rule out the latter, they argue that they are far more likely to be a brown dwarf than an ejected planet. An ejected giant planet is unlikely for two reasons. First, such planets are uncommon in general compared to planets with smaller masses. Second, most stars are low-mass stars, and giant planets are especially rare among those stars. As a result, it’s unlikely that most of the stars in IC 348 (which are low-mass stars) are capable of producing such massive planets. In addition, since the cluster is only 5 million years old, there probably hasn’t been enough time for giant planets to form and then be ejected from their systems. The discovery of more such objects will help clarify their status. Theories suggest that rogue planets are more likely to be found in the outskirts of a star cluster, so expanding the search area may identify them if they exist within IC 348. Future work may also include longer surveys that can detect fainter, smaller objects. The short survey conducted by the team was expected to detect objects as small as twice the mass of Jupiter. Longer surveys could easily reach one Jupiter mass. These observations were taken as part of Guaranteed Time Observation program 1229. The results were published in the Astronomical Journal. The James Webb Space Telescope is the world’s premier space science observatory. Webb is solving mysteries in our solar system, looking beyond to distant worlds around other stars, and probing the mysterious structures and origins of our universe and our place in it. Webb is an international program led by NASA with its partners, ESA (European Space Agency) and the Canadian Space Agency.

5 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) A NASA study expands the search for life beyond our solar system by indicating that 17 exoplanets (worlds outside our solar system) could have oceans of liquid water, an essential ingredient for life, beneath icy shells. Water from these oceans could occasionally erupt through the ice crust as geysers. The science team calculated the amount of geyser activity on these exoplanets, the first time these estimates have been made. They identified two exoplanets sufficiently close where signs of these eruptions could be observed with telescopes. The search for life elsewhere in the Universe typically focuses on exoplanets that are in a star’s “habitable zone,” a distance where temperatures allow liquid water to persist on their surfaces. However, it’s possible for an exoplanet that’s too distant and cold to still have an ocean underneath an ice crust if it has enough internal heating. Such is the case in our solar system where Europa, a moon of Jupiter, and Enceladus, a moon of Saturn, have subsurface oceans because they are heated by tides from the gravitational pull of the host planet and neighboring moons. NASA’s Cassini spacecraft captured this image of Enceladus on Nov. 30, 2010. The shadow of the body of Enceladus on the lower portions of the jets is clearly visible.NASA/JPL-Caltech/Space Science Institute These subsurface oceans could harbor life if they have other necessities, such as an energy supply as well as elements and compounds used in biological molecules. On Earth, entire ecosystems thrive in complete darkness at the bottom of oceans near hydrothermal vents, which provide energy and nutrients. “Our analyses predict that these 17 worlds may have ice-covered surfaces but receive enough internal heating from the decay of radioactive elements and tidal forces from their host stars to maintain internal oceans,” said Dr. Lynnae Quick of NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “Thanks to the amount of internal heating they experience, all planets in our study could also exhibit cryovolcanic eruptions in the form of geyser-like plumes.” Quick is lead author of a paper on the research published on October 4 in the Astrophysical Journal. The team considered conditions on 17 confirmed exoplanets that are roughly Earth-sized but less dense, suggesting that they could have substantial amounts of ice and water instead of denser rock. Although the planets’ exact compositions remain unknown, initial estimates of their surface temperatures from previous studies all indicate that they are much colder than Earth, suggesting that their surfaces could be covered in ice. The study improved estimates of each exoplanet’s surface temperature by recalculating using the known surface brightness and other properties of Europa and Enceladus as models. The team also estimated the total internal heating in these exoplanets by using the shape of each exoplanet’s orbit to get the heat generated from tides and adding it to the heat expected from radioactive activity. Surface temperature and total heating estimates gave the ice layer thickness for each exoplanet since the oceans cool and freeze at the surface while being heated from the interior. Finally, they compared these figures to Europa’s and used estimated levels of geyser activity on Europa as a conservative baseline to estimate geyser activity on the exoplanets. They predict that surface temperatures are colder than previous estimates by up to 60 degrees Fahrenheit (16 degrees Celsius). Estimated ice shell thickness ranged from about 190 feet (58 meters) for Proxima Centauri b and one mile (1.6 kilometers) for LHS 1140 b to 24 miles (38.6 kilometers) for MOA 2007 BLG 192Lb, compared to Europa’s estimated average of 18 miles (almost 29 kilometers). Estimated geyser activity went from just 17.6 pounds per second (about 8 kilograms/second) for Kepler 441b to 639,640 pounds/second (290,000 kilograms/second) for LHS 1140 b and 13.2 million pounds/second (six million kilograms/second) for Proxima Centauri b, compared to Europa at 4,400 pounds/second (2,000 kilograms/second). “Since our models predict that oceans could be found relatively close to the surfaces of Proxima Centauri b and LHS 1140 b, and their rate of geyser activity could exceed Europa’s by hundreds to thousands of times, telescopes are most likely to detect geological activity on these planets,” said Quick, who is presenting this research December 12 at the American Geophysical Union meeting in San Francisco, California. This activity could be seen when the exoplanet passes in front of its star. Certain colors of starlight could be dimmed or blocked by water vapor from the geysers. “Sporadic detections of water vapor in which the amount of water vapor detected varies with time, would suggest the presence of cryovolcanic eruptions,” said Quick. The water might contain other elements and compounds that could reveal if it can support life. Since elements and compounds absorb light at specific “signature” colors, analysis of the starlight would let scientists determine the geyser’s composition and evaluate the exoplanet’s habitability potential. For planets like Proxima Centauri b that don’t cross their stars from our vantage point, geyser activity could be detected by powerful telescopes that are able to measure light that the exoplanet reflects while orbiting its star. Geysers would expel icy particles at the exoplanet’s surface which would cause the exoplanet to appear very bright and reflective. The research was funded by NASA’s Habitable Worlds Program, the University of Washington’s Astrobiology Program, and the Virtual Planetary Laboratory, a member of the NASA Nexus for Exoplanet System Science coordination group.

This 360-degree mosaic from the “Airey Hill” location inside Jezero Crater was generated using 993 individual images taken by the Perseverance Mars rover’s Mastcam-Z from Nov. 3-6. The rover remained parked at Airey Hill for several weeks during solar conjunction.NASA/JPL-Caltech/ASU/MSSS Now at 1,000 days on Mars, the mission has traversed an ancient river and lake system, collecting valuable samples along the way. Marking its 1,000th Martian day on the Red Planet, NASA’s Perseverance rover recently completed its exploration of the ancient river delta that holds evidence of a lake that filled Jezero Crater billions of years ago. The six-wheeled scientist has to date collected a total of 23 samples, revealing the geologic history of this region of Mars in the process. One sample called “Lefroy Bay” contains a large quantity of fine-grained silica, a material known to preserve ancient fossils on Earth. Another, “Otis Peak,” holds a significant amount of phosphate, which is often associated with life as we know it. Both of these samples are also rich in carbonate, which can preserve a record of the environmental conditions from when the rock was formed. The discoveries were shared Tuesday, Dec. 12, at the American Geophysical Union fall meeting in San Francisco. “We picked Jezero Crater as a landing site because orbital imagery showed a delta – clear evidence that a large lake once filled the crater. A lake is a potentially habitable environment, and delta rocks are a great environment for entombing signs of ancient life as fossils in the geologic record,” said Perseverance’s project scientist, Ken Farley of Caltech. “After thorough exploration, we’ve pieced together the crater’s geologic history, charting its lake and river phase from beginning to end.” This image of Mars’ Jezero Crater is overlaid with mineral data detected from orbit. The green color represents carbonates – minerals that form in watery environments with conditions that might be favorable for preserving signs of ancient life. NASA’s Perseverance is currently exploring the green area above Jezero’s fan (center).NASA/JPL-Caltech/MSSS/JHU-APL Jezero formed from an asteroid impact almost 4 billion years ago. After Perseverance landed in February 2021, the mission team discovered the crater floor is made of igneous rock formed from magma underground or from volcanic activity at the surface. They have since found sandstone and mudstone, signaling the arrival of the first river in the crater hundreds of millions of years later. Above these rocks are salt-rich mudstones, signaling the presence of a shallow lake experiencing evaporation. The team thinks the lake eventually grew as wide as 22 miles (35 kilometers) in diameter and as deep as 100 feet (30 meters). Later, fast-flowing water carried in boulders from outside Jezero, distributing them atop of the delta and elsewhere in the crater. “We were able to see a broad outline of these chapters in Jezero’s history in orbital images, but it required getting up close with Perseverance to really understand the timeline in detail,” said Libby Ives, a postdoctoral fellow at NASA’s Jet Propulsion Laboratory in Southern California, which manages the mission. Enticing Samples The samples Perseverance gathers are about as big as a piece of classroom chalk and are stored in special metal tubes as part of the Mars Sample Return campaign, a joint effort by NASA and ESA (European Space Agency). Bringing the tubes to Earth would enable scientists to study the samples with powerful lab equipment too large to take to Mars. This animated artist’s concept depicts water breaking through the rim of Mars’ Jezero Crater, which NASA’s Perseverance rover is now exploring. Water entered the crater billions of years ago, forming a lake, delta, and rivers before the Red Planet dried up. NASA/JPL-Caltech To decide which samples to collect, Perseverance first uses an abrasion tool to wear away a patch of a prospective rock and then studies the rock’s chemistry using precision science instruments, including the JPL-built Planetary Instrument for X-ray Lithochemistry, or PIXL. At a target the team calls “Bills Bay,” PIXL spotted carbonates – minerals that form in watery environments with conditions that might be favorable for preserving organic molecules. (Organic molecules form by both geological and biological processes.) These rocks were also abundant with silica, a material that’s excellent at preserving organic molecules, including those related to life. “On Earth, this fine-grained silica is what you often find in a location that was once sandy,” said JPL’s Morgan Cable, the deputy principal investigator of PIXL. “It’s the kind of environment where, on Earth, the remains of ancient life could be preserved and found later.” Perseverance’s instruments are capable of detecting both microscopic, fossil-like structures and chemical changes that may have been left by ancient microbes, but they have yet to see evidence for either. PIXL, one of the instruments aboard NASA’s Perseverance Mars rover, analyzed the chemical makeup of an area of abraded rock dubbed “Ouzel Falls,” finding it rich in minerals containing phosphate, a material found in the DNA and cell membranes of all known life.NASA/JPL-Caltech/MSSS Analyzing this abraded rock patch dubbed “Bills Bay,” the PIXL instrument on NASA’s Perseverance Mars rover found it rich in carbonates (purple) and silica (green), both of which are good at preserving signs of ancient life. The image is overlaid with the instrument’s chemical data.NASA/JPL-Caltech/MSSS At another target PIXL examined, called “Ouzel Falls,” the instrument detected the presence of iron associated with phosphate. Phosphate is a component of DNA and the cell membranes of all known terrestrial life and is part of a molecule that helps cells carry energy. After assessing PIXL’s findings on each of these abrasion patches, the team sent up commands for the rover to collect rock cores close by: Lefroy Bay was collected next to Bills Bay, and Otis Peak at Ouzel Falls. “We have ideal conditions for finding signs of ancient life where we find carbonates and phosphates, which point to a watery, habitable environment, as well as silica, which is great at preservation,” Cable said. Perseverance’s work is, of course, far from done. The mission’s ongoing fourth science campaign will explore Jezero Crater’s margin, near the canyon entrance where a river once flooded the crater floor. Rich carbonate deposits have been spotted along the margin, which stands out in orbital images like a ring within a bathtub. More About the Mission A key objective for Perseverance’s mission on Mars is astrobiology, including the search for signs of ancient microbial life. The rover will characterize the planet’s geology and past climate, pave the way for human exploration of the Red Planet, and be the first mission to collect and cache Martian rock and regolith (broken rock and dust). Subsequent NASA missions, in cooperation with ESA (European Space Agency), would send spacecraft to Mars to collect these sealed samples from the surface and return them to Earth for in-depth analysis. The Mars 2020 Perseverance mission is part of NASA’s Moon to Mars exploration approach, which includes Artemis missions to the Moon that will help prepare for human exploration of the Red Planet. JPL, which is managed for NASA by Caltech in Pasadena, California, built and manages operations of the Perseverance rover.

NASA’s James Webb Space Telescope’s new view of Cassiopeia A (Cas A) in near-infrared light is giving astronomers hints at the dynamical processes occurring within the supernova remnant. Tiny clumps represented in bright pink and orange make up the supernova’s inner shell, and are comprised of sulfur, oxygen, argon, and neon from the star itself. A large, striated blob at the bottom right corner of the image, nicknamed Baby Cas A, is one of the few light echoes visible NIRCam’s field of view. In this image, red, green, and blue were assigned to Webb’s NIRCam data at 4.4, 3.56, and 1.62 microns (F444W, F356W, and F162M, respectively).NASA, ESA, CSA, STScI, D. Milisavljevic (Purdue University), T. Temim (Princeton University), I. De Looze (University of Gent) Supernova remnant Cassiopeia A (Cas A) shines in a new image from Dec. 10, 2023, from NASA’s James Webb Space Telescope. Webb’s Near-Infrared Camera (NIRCam) view of Cas A displays this stellar explosion at a resolution previously unreachable at these wavelengths, revealing intricate details of the expanding shell of material slamming into the gas shed by the star before it exploded. Cas A is one of the most well-studied supernova remnants in all the cosmos. Over the years, ground-based and space-based observatories, including NASA’s Chandra X-Ray Observatory, Hubble Space Telescope, and retired Spitzer Space Telescope have assembled a multiwavelength picture of the object’s remnant. However, astronomers have now entered a new era in the study of Cas A. In April 2023, Webb’s Mid-Infrared Instrument (MIRI) started this chapter, unveiling new and unexpected features within the inner shell of the supernova remnant. Many of those features are invisible in the new NIRCam image, and astronomers are investigating why. Read on to find out what we can learn from this new image of Cassiopeia A.

In 2023, as NASA pushed the limits of exploration for the benefit of humanity, the agency celebrated astronaut Frank Rubio becoming the first American astronaut to spend more than one year in space; delivered samples from an asteroid to Earth; sent a spacecraft to study a metal-rich asteroid for the first time; launched multiple initiatives to share climate data; advanced developments in sustainable aircraft; all while continuing preparations to send the first Artemis astronauts to the Moon. “This year, NASA continued to make the impossible, possible while sharing our story of discovery with the world,” said NASA Administrator Bill Nelson. “We’ve launched missions that are helping tell the oldest stories of our solar system; continued to safely transport astronauts to the International Space Station to conduct groundbreaking science; our Earth satellites are providing critical climate data to all people; we’re making great strides to make aviation more dependable and sustainable; and we’re growing our commercial and international partnerships as we venture back to the Moon and on to Mars. NASA is home to the world’s finest workforce, and there is no limit to what we can achieve when we work together.” In support of the Biden-Harris Administration’s efforts to address climate change, NASA is leading the development of U.S. government-wide initiatives focused on bringing Earth science information to the public. The Earth Information Center, a new interactive exhibit at NASA Headquarters in Washington, also includes an online experience that invites visitors to see Earth as NASA sees it from space while providing critical data needed by researchers and policymakers. Among other notable mentions, the agency’s James Webb Space Telescope – the largest, most powerful telescope humanity has ever put in space – celebrated one year of science. NASA and the Defense Advanced Research Projects Agency (DARPA) announced the two organizations will partner on DRACO (Demonstration Rocket for Agile Cislunar Operations) to test a nuclear-powered rocket in space as soon as 2027. This year NASA celebrated 25 years of International Space Station operations as the agency continued to foster the growth of the commercial space economy, supporting the development of commercial space station partnerships. It also marks the 65th anniversary of the agency. While celebrating these achievements, NASA also unveiled its NASA 2040 vision for the agency to ensure it remains a global leader in aerospace for decades to come. Below are additional highlights of NASA’s endeavors in 2023 to explore the unknown in air and space, innovate for the benefit of humanity, and inspire the world through discovery. Understanding Our Changing Planet NASA has used its unique vantage point of space to better understand our changing planet since launching its first Earth science satellites in the 1960s. In 2023, NASA’s Office of the Chief Scientist established a cross-agency working group and released a climate strategy. Other agency efforts to share scientific data on Earth.gov and other areas include: Working with its partners, NASA launched the U.S. Greenhouse Gas Center, opening access to trusted data on greenhouse gases. Data from NASA’s Earth Surface Mineral Dust Source Investigation (EMIT) instrument aboard the International Space Station is part of the gas center. EMIT identifies point-source emissions of greenhouse gases with a proficiency greater than expected. NASA’s tracking of greenhouse gases includes both global and focused estimates. Building on the month-by-month worldwide temperature data collected and released by NASA and National Oceanic and Atmospheric Administration both agencies are expected to announce soon 2023 was the warmest year in recorded history. A NASA airborne campaign helped show that methane ‘hot spots’ in the Yukon-Kuskokwim Delta are more likely to be found where recent wildfires burned into the tundra, altering carbon emissions from the land. After successfully launching to space earlier this year, NASA’s TEMPO (Tropospheric Emissions: Monitoring of Pollution) mission to study air quality now is successfully transmitting information about major air pollutants over North America. NASA’s SWOT (Surface Water and Ocean Topography) mission offered the its first detailed perspectives of Earth’s surface water. Among natural hazards, NASA data was put to use in monitoring the heavy rains occurring in the drought-stricken areas, heat waves, wildfires, and subsequent health affects worldwide, as well as expansion of NASA landslide data. Local students participate in an Earth Information Center (EIC) student engagement event, Friday, June 23, 2023, at the Mary W. Jackson NASA Headquarters building in Washington. The EIC is a new immersive experience that combines live data sets with cutting-edge data visualization and storytelling to allow visitors to see how our planet is changing.NASA/Keegan Barber The sample return capsule from NASA’s OSIRIS-REx mission is seen shortly after touching down in the desert, Sunday, Sept. 24, 2023, at the Department of Defense’s Utah Test and Training Range.

From left are: Jeremy Hansen, mission specialist; Victor Glover, pilot; Reid Wiseman, commander; and Christina Hammock Koch, mission specialist. The crew module is undergoing acoustic testing ahead of integration with the European Service Module. Artemis II is the first crewed mission on NASA’s path to establishing a long-term lunar presence for science and exploration under Artemis.NASA NASA’s X-59 sits in support framing while undergoing the installation of its lower empennage, or tail section, at Lockheed Martin Skunk Works in Palmdale, California in late March. Lockheed Martin/NASA Advancing Moon to Mars Exploration This year, NASA shared results of its first Moon to Mars Architecture Concept Review as it builds a blueprint for human exploration throughout the solar system for the benefit of humanity. The agency also continues to take significant steps toward landing the first woman and first person of color on the Moon as part of Artemis. Notably in 2023, NASA announced crew for the Artemis II mission, the first Artemis mission with astronauts around the Moon and back to Earth. The crew completed fundamentals training, and is now focusing on training for mission operations. Additional highlights for human deep space exploration include: All major elements for the SLS (Space Launch System) rocket for Artemis II are complete or nearing completion including booster segments delivered to NASA’s Kennedy Space Center in Florida and final core state assembly testing at NASA’s Michoud Assembly Facility in New Orleans. Upgrades and refurbishments continue at Kennedy with the mobile launcher and launch pad, including a water flow test and launch operations simulation. NASA made progress on Artemis III, which will send the first humans to explore the region near the lunar South Pole, building on the previous flight tests and adding a human landing system and advanced spacesuits for moonwalks. The solid rocket booster segments and the four RS-25 engines are complete for the Artemis III SLS, as well as three of the five major core stage elements. Teams are integrating elements of Orion’s crew module, and the European Service Module. NASA selected the geology team to develop a lunar surface science plan for Artemis III. Beyond Artemis III, teams completed welding the primary structure for Gateway’s HALO (Habitation and Logistics Outpost), where astronauts will live and work in lunar orbit. Fabrication is complete on the primary structure of the Power and Propulsion Element that will provide power, communications, and maintain Gateway’s orbit. In addition to other hardware assembly and certification work for later missions, Artemis V will include a lunar terrain vehicle. NASA asked SpaceX to further develop Starship for Artemis IV, and also selected Blue Origin to develop a human lunar lander for Artemis V. Experiments aboard the International Space Station focused on helping astronauts go farther and stay longer in space. This research included growing sustainable crops such as dwarf tomatoes, understanding how microbes adapt to space to protect crew health, and developing innovative materials that can weather the harsh environments of the Moon and Mars. To support future NASA Moon missions with crew, the agency’s CLPS (Commercial Lunar Payload Services) initiative is in the final phases of preparations for the first two launches and landings to deliver NASA science and technology demonstrations to the lunar surface. Five NASA payloads are aboard Astrobotic’s Peregrine Mission 1 lander, which is set to launch no earlier than Monday, Jan. 8. Soon after, another six NASA payloads will launch no earlier than Friday, Jan. 12, aboard Intuitive Machine’s Nova-C spacecraft. Since launching CLPS, NASA has contracted with five companies for eight deliveries to the lunar surface. Most recently in 2023, NASA selected Firefly Aerospace for a delivery. Among future CLPS payloads is NASA’s first robotic lunar rover, VIPER – short for the Volatiles Investigating Polar Exploration Rover. The rover will trek into permanently shadowed areas to unravel the mysteries of the Moon’s water and better understand the environment. In preparation for a landing in late 2024, scientists named VIPER’s mission area in honor of NASA mathematician Melba Roy Mouton. Development, assembly and testing also continues for the rover’s solar and battery systems. While NASA is leading Artemis, international partnerships are a key part of advancing Moon to Mars exploration. In 2023, 10 additional countries signed the Artemis Accords, which lay out a common set of principles governing the civil exploration and use of outer space. So far, 33 countries have signed the Artemis Accords. Maintaining Low Earth Orbit Operations Closer to Earth, the International Space Station – humanity’s home in space – passed 25 years of operations. NASA and its partners officially extended operations plans for the microgravity science laboratory for the benefit of humanity. Other space station milestones in 2023 include: NASA and SpaceX continued regular crew rotation flights to and from station, helping maximize science in space, including: NASA astronauts Frank Rubio, Nicole Mann, Josh Cassada, Stephen Bowen, Woody Hoburg, Loral O’Hara, and Jasmin Moghbeli lived and worked aboard the station. Rubio spent a U.S. record-breaking 371 days in space, contributing to a better understanding of long-duration spaceflight as we explore beyond our home planet. Crew-5 returned to Earth with Mann and Cassada, as well as JAXA (Japan Aerospace Exploration Agency) astronaut Koichi Wakata, and Roscosmos cosmonaut Anna Kikina. Crew members tested hydroponic and aeroponic techniques to grow plants without using soil, released Uganda and Zimbabwe’s first satellites, studied how liquids move in a container in simulated lunar gravity to generate data to improve Moon rover designs, and reinstalled the station’s bioprinting facility. Crew-6 included Bowen and Hoburg, as well as UAE (United Arab Emirates) astronaut Sultan Alneyadi and Roscosmos cosmonaut Andrey Fedyaev. The crew assisted a student robotic challenge, studying plant genetic adaptations to space, and monitoring human health in microgravity. The crew also released Saskatchewan’s first satellite, which tests a new radiation detection and protection system. Crew-7 carried Moghbeli, ESA (European Space Agency) astronaut Andreas Mogensen, JAXA astronaut Satoshi Furukawa, and Roscosmos cosmonaut Konstantin Borisov. This crew is conducting a variety of scientific research in areas such the collection of microbial samples from the exterior of the space station, the first study of human response to different spaceflight durations, and a study on astronaut’s sleep. NASA and Boeing continued to make progress on the company’s CST-100 Starliner spacecraft. Starliner and its crew of NASA astronauts Barry Wilmore and Sunita Williams are preparing for the first flight with astronauts in 2024, the final demonstration prior to regular flights to the microgravity complex. Space station crew members completed 12 spacewalks to upgrade and conduct maintenance at the orbiting laboratory before the year’s end. NASA astronauts continued work to install the International Space Station Rollout Solar Arrays (IROSA), which will increase power generation capability by up to 30% when fully complete. Six commercial cargo missions and international partner missions delivered about 28,000 pounds of science investigations, tools, and critical supplies to the space station. By year’s end about 12,500 pounds of investigations and equipment are planned to be returned researchers on Earth. Space station crew members welcomed the second NASA-enabled private astronaut mission, Axiom Mission 2, to the orbital complex advancing the agency’s goal of commercializing low-Earth orbit. NASA also selected Axiom Space for the third private astronaut mission and signed an order for the fourth mission with the company. Some additional key investigations launched, and operating, on station included NASA and ISS National Lab releasing a joint solicitation to address the goals of the Biden-Harris Administration’s Cancer Moonshot initiative, which aims to conduct science in space to help cure disease on Earth; NASA’s ILLUMA-T (Integrated Laser Communications Relay Demonstration Low-Earth-Orbit User Modem and Amplifier Terminal) is now on station, which aims to test high data rate laser communications via the agency’s LCRD (Laser Communications Relay Demonstration); upgraded NASA’s Cold Atom Laboratory to continue pioneering quantum discovery in space; and launched and installed its Atmospheric Wave Experiment on station to provide insight into how terrestrial weather impacts space weather, which may affect satellite communications and tracking in orbit. Also on the commercial front, NASA partnered with seven U.S. companies with unfunded Space Act Agreements, and released its third Request for Information for commercials space station services, while working toward a formal call for proposals to provide the agency with low Earth orbit services after the space station’s retirement. Commercial space station partners met major design and engineering milestones, and are on track to serve as potential replacements for the agency’s microgravity research needs. Two companies also are combining efforts, which will allow NASA to apply funding to the other stations to accelerate development. Reaching Farther into Solar System, Beyond As part of its first year of operations, NASA’s Webb telescope pulled back the curtain on some of the farthest galaxies, stars, and black holes ever observed; solved a longstanding mystery about the early universe; found methane and carbon dioxide in the atmosphere of a planet outside our solar system; and offered new views and insights into our own cosmic backyard. Additional achievements beyond the solar system included: NASA made important contributions to two missions that international partners launched this year: ESA’s Euclid mission to study dark energy and dark matter, as well as JAXA’s XRISM mission, a powerful new satellite that will revolutionize how we understand the hot, X-ray universe. The Nancy Grace Roman Space Telescope, NASA’s next flagship observatory, finished camera assembly, and its coronagraph instrument passed its first big optics test. Autumn was host to mission milestone events that showcased the importance of our solar system’s smaller bodies. NASA’s OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification, and Security-Regolith Explorer) spacecraft capped its seven-year journey with the successful deposit of a pristine sample of surface material from the asteroid Bennu in the Utah desert. NASA showed off material from the asteroid Bennu for the first time. Initial studies of the 4.5-billion-year-old asteroid Bennu sample collected in space and brought to Earth show evidence of high-carbon content and water, which together could indicate the building blocks of life on Earth may be found in the rock. The Psyche spacecraft launched from NASA Kennedy toward the asteroid Psyche. NASA’s Lucy spacecraft conducted its first target asteroid flyby of asteroid Dinkinesh at the inner edge of the main asteroid belt, and the first images now are online. An annular eclipse occurred on Oct. 14, visible in parts of the United States, Mexico, and many countries in South and Central America. NASA supported the event with engagement activities, as well as science research. Three Black Brant IX sounding rockets were launched to study the ionosphere – an electrically charged layer of the atmosphere – before, during, and after the peak eclipse. NASA also kicked off Heliophysics Big Year, a public engagement campaign to make science and information accessible to all and showcase heliophysics-related efforts. Technology Innovations to Benefit All NASA’s Deep Space Optical Communications experiment launched aboard the Psyche spacecraft and achieved first light, beaming back a laser encoded with test data from nearly 10 million miles away. NASA will demonstrate data transmission rates 10 to 100 times greater than current radio frequency systems. The following are additional space technology advancements: Partnered with Aerojet Rocketdyne for qualification testing on the Advanced Electric Propulsion System, a cutting-edge solar electric propulsion thruster that will propel Gateway. NASA provided two navigation systems to Astrobotic for use on its CLPS flight: a Navigation Doppler Lidar to provide enhanced guidance and navigation capabilities, and the Terrain Relative Navigation to increase landing accuracy and help avoid hazards near the surface.

5 Min Read Seeing and Believing: 15 Years of Exoplanet Images Beta Pictoris is located about 60 light-years away toward the constellation of Pictor (the Painter’s Easel) and is one of the best-known examples of a star surrounded by a dusty debris disk. Earlier observations showed a warp of the disc, a secondary inclined disc and comets falling onto the star, all indirect, but tell-tale signs that strongly suggested the presence of a massive planet. Observations by ESO proved the presence of a planet around Beta Pictoris, and another planet was later discovered. To see the planets, we must block the light of the star. Credits: ESO/Digitized Sky Survey 2 First there was a gloriously dusty disk. Then the traceable tracks of “exocomets.” But 15 years ago this fall, the star system Beta Pictoris yielded one of the most iconic pictures in astrophysics: a direct image of a planet orbiting another star. The young, bright star, some 63 light-years distant and visible to the naked eye, all but overwhelmed the faint light of the planet. When astronomers, using a European Southern Observatory telescope, subtracted the starlight, all that remained of the planet was a tiny dot, a few pixels. But it was enough to throw open a new window on direct imaging. This composite image represents the close environment of Beta Pictoris as seen in near infrared light. The exoplanet Beta Pictoris b is the small dot next to the masked star at the center. This very faint environment is revealed after a very careful subtraction of the much brighter stellar halo. The outer part of the image shows the reflected light on the dust disk, as observed in 1996 by a European Southern Observatory ground telescope. The newly detected source is more than 1000 times fainter than Beta Pictoris, aligned with the disc, at a projected distance of 8 times the Earth-Sun distance. ESO/A.-M. Lagrange et al. “After that, I knew what I wanted to do in astronomy,” said Marie Ygouf, a researcher who specializes in direct imaging of exoplanets – planets around other stars – at NASA’s Jet Propulsion Laboratory in Southern California. An undergraduate when she first saw the image of the planet, called Beta Pictoris b, Ygouf said she was awestruck. “It was so exciting to try to take pictures of exoplanets, to try to detect life on another planet,” she said. “I was sold.” Today the Beta Pictoris system, called Beta Pic for short, is famous for the early, breathtaking images of its surrounding disk of dusty debris, and for abundant evidence of exocomets, or comets detected in star systems other than our own. The discovery of a second planet in the system, Beta Pictoris c, was revealed to much scientific excitement in 2018. It is, as one astronomer said, the gift that keeps on giving. But the scientists deeply involved in early observations of the system had a bit of an uphill struggle convincing some colleagues that their groundbreaking discoveries were real, said Anne-Marie Lagrange, an astronomer at LESIA, Observatoire de Paris, who has been working to understand the system for more than 30 years. As an intern, Lagrange began her work on Beta Pic in the mid-1980s, just after the disk image made its big splash. Among her research milestones was the discovery, in the late 1980s, of massive clumps of gas falling onto the surface of the system’s central star – and at high rates of speed, up to 200 miles (350 kilometers) per second. Lagrange and her fellow researchers relied on observations from the IUE (International Ultraviolet Explorer) satellite – “an ancestor” of NASA’s Hubble Space Telescope, she said – to propose that the infalling gas was caused by evaporating comets. “They were the first exocomets [observed] around another star,” she said. “At the beginning, many people were laughing at it.” The findings held up, and the presence of exocomets in the system was confirmed by further observations announced in 2022. With this technique, we may be able to answer that very fundamental question: Is there any life in the universe outside of Earth?” Marie Ygouf Researcher on the Nancy Grace Roman Space Telescope science team In the mid 1990s, relying on the recently launched Hubble as well as increasingly sophisticated ground-based instruments, scientists realized that the debris disk around Beta Pictoris was warped, like a vinyl record left too long in the Sun. Computer modeling results suggested the warp was a gravitational skew caused by an orbiting planet. And in 2008, after long effort, Lagrange and her team hit paydirt: a direct image of the giant, gaseous planet, so young it was still glowing from its recent formation. “The nice thing is, we predicted it 10 years before,” she said. The future of exoplanet imaging Still a relatively minor player in the detection of exoplanets, direct imaging’s role will expand in the years and decades to come, promising deep insights into the nature of distant planets as technology improves. But even then, each “image” of a planet will still be just a handful of pixels. That might sound disappointing, especially in the era of spectacular sci-fi movie effects. If we find an “Earth-like” planet, we won’t see continents and oceans – at least not yet. But that tiny dot of light will contain a flood of information: details of the planet’s atmosphere, clouds, temperature, and perhaps even signs of some form of life. By splitting the light from that tiny dot into a spectrum of colors, scientists can spot missing lines from that spectrum – slices of light absorbed by molecules in the planet’s atmosphere as starlight is reflected from the atmosphere or surface. The missing slices correspond to specific gases and molecules in the planet’s atmosphere, a detection method known as spectroscopy. NASA’s James Webb Space Telescope is already using onboard spectrographs to tease out the components of exoplanet atmospheres. In the years ahead, the agency’s Nancy Grace Roman Space Telescope, to be launched by May 2027, is designed to study the cloudy atmospheres of mature, Jupiter-sized exoplanets. The Habitable Worlds Observatory, a mission concept now in the early planning stages, is expected to refine this technology, to measure the atmospheric composition of small, rocky planets like our own, all from those little dots of directly imaged exoplanets. Ygouf is part of the project science team for the Roman telescope’s coronagraph instrument, which will block the glare from a parent star so the light from its planets can be detected. Meant to be a technology demonstration, the instrument includes two flexible mirrors to correct distortions in the light caused by the instrument and by the telescope itself. She says the direct imaging techniques that caught fire with Beta Pictoris could someday solve one of the ultimate mysteries. “With this technique, we may be able to answer that very fundamental question: Is there any life in the universe outside of Earth?” she said. “It’s astonishing, incredible, that from a few pixels we’ll be able to learn so many things about a planet: whether those planets are terrestrial or gaseous, whether they have an atmosphere or not. If it’s done right, in the future we may be able to create pretty maps of those planets, seeing potential clouds. It may be a few pixels, but [there’s] so much information you can get from that.” Share Details Last Updated Dec 12, 2023 Related Terms Exoplanet DiscoveriesExoplanet TransitsExoplanetsHubble Space TelescopeJames Webb Space Telescope (JWST)Nancy Grace Roman Space TelescopeUncategorized Explore More 3 min read NASA’s Hubble Space Telescope Returns to Science Operations Article 4 days ago 2 min read Hubble Captures a Cluster in the Cloud Article 4 days ago 6 min read Hubble Celebrates 30th Anniversary of Servicing Mission 1 Article 2 weeks ago View the full article

NASA 2023: Nothing is Beyond Our Reach

5 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) Some of the same properties of light and optics that make the sky blue and cause rainbows can also help scientists unlock mysteries about cloud formation and the effects of tiny particles in our air. NASA’s upcoming PACE mission will offer important insights on airborne particles of sea salt, smoke, human-made pollutants, and dust – collectively called aerosols – by observing how they interact with light. With PACE data, scientists will provide better answers to key questions such as how aerosols affect cloud formation or how ice clouds and liquid clouds differ. Understanding the nature of airborne particles and clouds is crucial to deciphering how climate and air quality are changing. Two instruments on NASA’s upcoming PACE mission will look at aerosols and clouds – the A and C in the name of the Plankton, Aerosol, Cloud, ocean Ecosystem satellite. After launch in early 2024, the PACE mission will scan the Earth and gather data on the chemical composition, movement, and interaction of aerosols and clouds through the use of two cutting-edge polarimeters – instruments that measure light properties. Credit: NASA’s Goddard Space Flight Center Download this video in HD formats from NASA Goddard’s Scientific Visualization Studio: https://svs.gsfc.nasa.gov/14454/ There are characteristics of light that we can see with our eyes, such as color. Other characteristics are invisible to the human eye, like what scientists call polarization. “Polarization is something that we don’t have an intuitive sense for because our eyes don’t see it,” said Kirk Knobelspiesse, polarimetry lead for the PACE mission at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “If you saw the world through eyes that could see polarization, like our sensors can, you would see rainbows everywhere.” Light leaving the Sun moves in all different directions like a wave – this is called unpolarized light, said Brian Cairns, deputy project scientist for PACE. When it interacts with something like a cloud or an aerosol particle, however, light can oscillate more in one direction than the others: It is now polarized light. This quirk of light behavior can help scientists learn more about the characteristics and interactions of aerosols and water droplets in the sky. Polarimeters measure the angle at which the light is polarized, which reveals specific characteristics of whatever the light had bounced off of. With these instruments, scientists can piece together the size, composition, abundance, and other traits of the particles in the atmosphere. An example of a cloud bow, taken late on a winter afternoon in Santa Cruz, California. The cloud in this case was light coastal fog, so this could also be referred to as a fog bow. In the scene, the sun was positioned low in the sky directly behind the viewer so that backscattered light is observed. While this observation geometry is rare from the surface of the earth, it will be common for PACE/HARP2.NASA/Kirk Knobelspiesse The two polarimeters on PACE – HARP2 and SPEXone – make a great pair because of the complementary differences in what they measure. HARP2, built at the University of Maryland, Baltimore County, will observe four wavelengths of light from up to 60 different angles. SPEXone, built at the Netherlands Institute for Space Research (SRON) and Airbus Netherlands B.V., will peer down at a narrower swath, using five viewing angles but looking at light at hyperspectral resolution – the full range of colors in a rainbow. Together the polarimeters will offer a picture of Earth’s atmosphere in unprecedented detail. Scientists have been observing aerosols from space for decades, though the community has not had polarimetry data for a decade, noted Otto Hasekamp, senior scientist at SRON. PACE will provide polarimeter data from multiple vantage points and, due to technological advancements in the instruments, the data will be of better quality than ever before. “It’s exciting to see the culmination of working actively on instrument models and prototypes,” said Jeroen Rietjens, instrument scientist at SRON, “then finally seeing it end up on a real satellite.” Jeroen Rietjens in Goddard cleanroom with PACE. “Very proud to be in the Goddard cleanroom and to pose with the fully assembled and tested PACE satellite, which hosts our small SPEXone instrument. The instrument is neatly wrapped in grey thermal blankets and still has the red radiator cover in place. It is surreal to realize that In a few months it will be staring at the Earth and collecting multi-angle spectro-polarimetric data that will enable scientists to infer the amount and type of aerosols in the Earth atmosphere and contribute to a better understanding of the effects of aerosols on climate,” said Rietjens.NASA/Denny Henry After PACE is launched in early 2024, the satellite will scan Earth every two days, gathering immense quantities of data on the chemical composition, movement, and interaction of aerosols and clouds. “We want to measure properties of aerosols because aerosols affect climate,” said Hasekamp. They reflect light back into space and can also absorb it, which plays a role in how much of the Sun’s energy reaches Earth’s surface. Aerosols also affect cloud formation and properties, but the details of these relationships are not fully known to scientists. The data PACE collects will help to clarify some of these unknowns. The new polarimetry data will also offer real-time insights on air pollution. “PACE measurements will not only answer fundamental science questions, but will also improve people’s quality of life,” said Marcela Loría-Salazar, assistant professor at the School of Meteorology at the University of Oklahoma and PACE early adopter. The PACE Early Adopters program promotes the integration of PACE data into practical applications of science. Loría-Salazar is particularly interested in how aerosols change over time and with location, with an extra emphasis on the altitude of aerosols over the middle of the United States. There, PACE will allow scientists to identify aerosols, while also deciphering what they mean for air quality. The measurements from PACE’s polarimeters will also help improve our understanding of Earth’s climate. By adding PACE atmospheric data to models, scientists will be able to replace the estimates now used to fill data gaps in those models with data from current measurements. “I’m hoping to help gather the data that will reduce model uncertainty and help us make better predictions for how we expect our climate to play out in the next decades and centuries,” Knobelspiesse said.

Three NASA-funded commercial space station partners are on track for the design and development of their orbital destinations and the transition of agency’s low Earth orbit needs from the International Space Station. “We are ending the year on a high note with multiple important milestones being completed by our partners,” said Angela Hart, manager of the Commercial Low Earth Orbit Development Program at NASA Johnson Space Center in Houston. “Over the past few months, we have been able to dig into the details of the specific hardware and processes of these stations and are moving forward to multiple comprehensive design reviews next year.” Axiom Space A hatch of the Axiom Hab One module, which will attach the module to the International Space Station.Axiom Space Axiom Space, which holds a firm-fixed price, indefinite-delivery, indefinite-quantity contract with NASA, is on schedule to launch and attach its first module, named Axiom Hab One, to the International Space Station in 2026. A total of four modules are planned for the Axiom Commercial Segment attached to the station. After the space station’s retirement, the Axiom Commercial Segment will separate and become a free-flying commercial destination named Axiom Station. The hatches of the Axiom Hab One module are fabricated and prepared to undergo pressure testing to ensure a strong enough seal to withstand the vacuum of space. Manufacturing of the Axiom Hab One module is underway, and the critical design review will occur in 2024. During this review, NASA will assess the maturity of the Axiom Space design and provide feedback necessary to ensure safe operations when it is attached to the International Space Station. Orbital Reef NASA engineers work alongside Blue Origin team members to conduct testing on prototype windows for the Orbital Reef commercial space station. Blue Origin Blue Origin, which NASA awarded a Space Act Agreement in 2021 to develop a free-flying space station named Orbital Reef, recently completed tests for a window system and a structural demonstration. For the structural test, Blue Origin used a prototype of their space station’s main module, called the Core, to demonstrate the manufacturing processes required to build the final pressurized modules of the station. The test supports validation of the structural models and analytical tools for the Core’s structural design. The International Space Station’s cupola, a room with seven windows overlooking the Earth, is the cornerstone of crewed missions for both research and astronaut morale. Orbital Reef will incorporate multiple windows on its Core, with each window spanning about twice the size of a car windshield. For the window test, Blue Origin evaluated the window integration structure design concept and its performance against the pressures and temperatures the windows will be exposed to while in orbit. Starlab A test unit of a water recovery system used on board the International Space Station in 2015 that helped transform urine from crew members into usable water. NASA NASA also awarded Starlab, a station being developed by Voyager Space’s Exploration Segment, a Space Act Agreement in 2021. Voyager Space recently announced a partnership with Airbus and Northrop Grumman. Voyager’s Exploration Segment, which includes Nanoracks, recently completed three milestones: a system definition review and the initiation of two pairs of milestones for an optical link demonstration and alternative urine processor demonstration. Free-space optical, also called laser communications, allows for higher data rates and more energy-efficient communications than radio frequency communication systems. A major goal of the optical communication demonstration is to conduct testing from the International Space Station to the ground to establish the capabilities needed for Starlab. This initial milestone, within the optical link demonstration milestone pair scope, validated the Starlab testing plan. The optical link is planning to be tested next on the International Space Station. As on the International Space Station, Starlab will recover purified water from urine to reduce water needed to resupply the station. Starlab will test an alternative urine processor under realistic operating conditions to validate functional performance and reduce implementation risk. Similar to the optical link demonstration, the processor demonstration is divided into a pair of milestones, with this initial completed milestone validating the testing plan. Starlab’s third recently completed milestone was a system definition review. Teams examined how NASA’s potential commercial space station requirements aligned to the functional areas of the Starlab system to define the space station architecture. The completion of this milestone initiated preparations for the next step in the comprehensive review process, the preliminary design review. NASA is working closely with commercial companies to develop new space stations capable of providing services to NASA and others, which will ensure that the U.S. maintains a continuous human presence in low Earth orbit and provides direct benefits for people on Earth. Leading into NASA’s future procurement for commercial low Earth orbit services, the agency recently released its third request for information.

3 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) NASA engineers Josh Greiner, a native of Dothan, Alabama (left) and Peyton Pinson, a Madison, Mississippi native, stand at NASA’s Stennis Space Center, outside the building where they began as interns in 2016. Almost eight years later, the two are part of a team that leads engine tests for NASA and commercial companies at the nation’s premier rocket engine test site. NASA/Danny Nowlin The last Wednesday in November proved to be a full-circle moment for two engineers at NASA’s Stennis Space Center near Bay St. Louis, Mississippi. Josh Greiner heard a familiar voice on the headset as he prepared to conduct an RS-25 engine test on the Fred Haise Test Stand on Nov. 29. It was Peyton Pinson, speaking from the same nearby test complex building where he and Greiner once shared a cubicle as interns seven years earlier. As Greiner listened in, Pinson announced he would conduct a hot fire on the E-1 Test Stand for commercial company Launcher Space in 30 minutes. “It was a pretty cool moment,” Greiner said. “We used to sit there and look at the test conductor kind of in awe and were amazed they could keep up with all these different console operators at the same time. Now, we both are part of the test team and both part of the rotation that gets to conduct tests.” Pinson and Greiner arrived at NASA Stennis in May 2016 to participate in the NASA Pathways work study (co-op) program. Pinson was a mechanical engineering major at Mississippi State University in Starkville. Greiner, still unsure of what direction he wanted to go in the field, was majoring in aerospace engineering at the University of Alabama in Tuscaloosa. He ultimately finished with a mechanical engineering degree and credits his work study experience for providing clarity for his future. “If you can get a co-op, I’m 100 percent in favor of that,” Greiner said. “You get exposure to a breadth of disciplines that make it a lot easier to start narrowing in what you really want to do. In college, we all come out with a pretty standardized foundation of engineering that’s an incredible knowledge base, but you really learn a lot with on-the-job training. Getting to the right place with the right people is going to help your growth more so than getting the perfect engineering degree.” The right place proved to be NASA Stennis. Pinson and Greiner spent multiple semesters soaking up knowledge from the experienced, diverse workforce at the south Mississippi NASA center. They rotated throughout the center complex where teams fulfill NASA and commercial space company test needs. “When we started as co-ops, Josh and I were given a good bit of responsibility and trusted with a lot,” Pinson said. “We had so many people who were a part of the team that really wanted to help us learn and develop and get to where we are now.” After completing the work-study program and earning their degrees, Pinson and Greiner were hired by NASA in 2018. “Our management put us in a position to be successful,” Greiner said. “We started running consoles as co-ops, and they helped move us onto the test stands with projects that had a lot going on and gave us a huge share of responsibility in leading projects early in our career.” Both now have years of experience that includes conducting various engine tests, such as the successful Nov. 29 hot fires at the nation’s premier rocket engine test site. “We all work together in the mechanical operations group to get to that point,” Pinson said. “There’s a lot of opportunity for a new mechanical operations engineer to learn along the way and to sit in the test conductor seat with an experienced test conductor to back you up and guide you through it. Eventually, you have enough on-the-job training to run it yourself.” For information about the NASA Pathways program, visit: NASA Careers: Pathways – NASA Share Details Last Updated Dec 12, 2023 EditorNASA Stennis CommunicationsContactC.

Commander Jeff Williams poses for a photo in the Quest Airlock (A/L) with all of his mission patches. The patches are, from left, STS-101, Soyuz TMA-8, Expedition 13, Soyuz TMA-16, Expedition 21, Expedition 22, Soyuz TMA-20M, Expedition 47, and Expedition 48.Credit NASA Dec. 11, 2023 RELEASE: J23-007 NASA astronaut and retired U.S. Army Col. Jeffrey Williams, who played a key role in the design, construction, and operation of the International Space Station, is retiring on Sunday, Jan. 14, 2024, after more than 27 years of service at the agency. The two-time station commander spent 534 cumulative days in space spanning four trips to the space station. He spent nearly 32 hours outside of the orbital laboratory on five spacewalks. “Jeff’s dedication and commitment to advancing NASA’s mission for the benefit of all humanity is truly admirable,” said NASA Johnson Space Center Director Vanessa Wyche. “His willingness to go above and beyond has impacted several generations and will continue to inspire future generations to come.” In addition to his time in space, he tested and evaluated the space station’s U.S. laboratory module Destiny during its final assembly at NASA’s Marshall Space Flight Center in Huntsville, Alabama, led the development of a space shuttle cockpit upgrade, worked in legislative affairs at NASA Headquarters in Washington, commanded a nine-day NEEMO (NASA Extreme Environment Mission Operations) mission in the Aquarius undersea habitat off the coast of Florida, and worked extensively in spacewalk development. Since 2017, he has been assistant director of Flight Operations at NASA’s Johnson Space Center in Houston. Among his many accomplishments, he served as chair of the Multinational Crew Operations Panel, responsible for International Space Station crew assignments, qualifications, and training. Most recently, he served on a review board overseeing development of lunar surface projects for the Moon to Mars architecture. “I had the pleasure of working with Jeff from the very beginning of our careers – first in the earliest days of the space station, and now working together to put the next humans on the Moon,” said Norm Knight, director of flight operations, NASA Johnson. “Over the course of his 27 years with us, I’ve always admired his leadership, mentorship, and passion for all things spaceflight. He will be so missed, and I’m excited to see what comes next for him.” The Wisconsin native joined NASA Johnson on a four-year Army assignment supporting the Space Shuttle Program in 1987. He was selected to join the NASA astronaut class of 1996. His first mission was on the crew of STS-101, launching on space shuttle Atlantis for the third mission devoted to station construction. His first long duration mission was Expedition 13, launching in March 2006 on Soyuz TMA-8 and lasting six months as station construction resumed with the shuttle return-to-flight after the Columbia accident. For his third flight, Expeditions 21/22, Williams launched in October 2009 aboard Soyuz TMA-16 for another six-month stay – this time to integrate the station’s Tranquility module and its cupola to complete station construction. Williams’ final spaceflight launched in March 2016 on Soyuz TMA-20M for Expeditions 47/48 which saw the arrival of the station’s Bigelow Expandable Activity Module, the integration of an international docking adaptor for commercial crew spacecraft, and the continuation of science and technology demonstrations. “It has been a tremendous honor and privilege to work with the best team in the world here at NASA,” Williams said, “and to share in what has to be the greatest technological and operational achievement in human history – the International Space Station – designed and built in many different places and countries on the planet, assembled and integrated off the planet, and continually operated for now more than 25 years, all in the context of international partnership. I am incredibly grateful to the many friends, mentors, and coworkers I’ve been privileged to labor with, who span three generations and range from those who worked in the Apollo Program all the way to the newest team members now dedicated to returning to the Moon.” Overall, Williams lived and worked with 56 different individuals from eight different countries aboard the orbital outpost. His flights spanned 16 years of the space station’s assembly, construction, and emerging operational capability. He contributed to hundreds of scientific experiments and a broad spectrum of technology development projects. Prior to becoming an astronaut, Williams attended the U.S. Military Academy at West Point, New York, where he earned a bachelor’s degree in Applied Science and Engineering, the U.S. Naval Postgraduate School in Monterey, California, where he earned a master’s degree in Aeronautical Engineering, and the U.S. Naval War College, Newport, Rhode Island, where he earned a master’s degree in National Security and Strategic Studies. He served in the 3rd Armored Division’s 503rd Aviation Battalion as an Army aviator in West Germany. He attended Naval Test Pilot School, graduating first in his class in 1992 and then served as an experimental test pilot before becoming an astronaut. He retired from Army active duty in 2007 with more than 27 years of military service and 3,100 hours in more than 50 different aircraft. His experience has spanned more than 47 years.

“There’s this thing called the overview effect: Space has this effect on people that you could probably call almost spiritual. Everyone returns from spaceflight changed in one way or another. … They see the Earth from space, and that’s how they continue to see it after flight. “… The more people travel to space and have the experience of seeing the Earth, the less chance of wars and conflict and separation we have. Life becomes more hopeful. “I read [‘The Last Man on the Moon’] by Gene Cernan, and he was describing how he felt looking at the Earth from the surface of the Moon. I was like, ‘Yeah, there’s something there.’… I feel like we go to space not to learn more about space but to learn more about ourselves.” — Margarita Sampson, Branch Chief, NASA’s Johnson Space Center Image Credit: NASA / William Stafford Interviewer: NASA / Michelle Zajac Check out some of our other Faces of NASA.

Call for Papers Date: August 13–14, 2024 Location: Washington, D.C. Jointly organized by the NASA History Office and the Earth Science Division, this workshop seeks to document the important contributions of airborne campaigns implemented on NASA’s DC-8 Airborne Science Laboratory. The workshop will be a combination of keynote talks, panel discussions, and roundtables. The intention is to publish an anthology of selected papers of key presentations. NASA’s DC-8 aircraft recently completed nearly four decades of service to NASA with its retirement in early 2024 following the completion of the ASIA-AQ campaign. The DC-8, which NASA acquired in 1985, was a workhorse aircraft for NASA’s Airborne Science Program of NASA’s Earth Science Division (ESD), serving as the primary platform—or one of several platforms—of many airborne campaigns. Its contributions are legendary from flying as part of the first polar stratospheric ozone campaigns in the late 1980s, through campaigns focused on ice sheets, sea ice, terrestrial ecology, greenhouse gases, and air quality that continued throughout its lifetime. DC-8 Airborne Laboratory in flight Besides the process knowledge that the DC-8 provided, it served as an important proving ground for new instrumentation and techniques that helped pave the way for their eventual use in ESD’s space flight program, a source of calibration/validation data for ESD’s satellite instruments, and as a flying laboratory for students, post-docs and early career professionals to design, build, and test instruments, acquire data, and analyze it. It also was the primary platform for NASA’s now 15-year-old Student Airborne Research Program (SARP), which has provided hands-on opportunities for well over 400 young scientists and has an outstanding “STEM retention rate” for its past participants. NASA Student Airborne Research Program students, mentors and faculty pose in front of NASA’s DC-8 on December 7, 2021 at Armstrong Flight Research Center Building 703. In this workshop, the ESD and related investigator communities are invited to share examples of the scientific, programmatic, and human achievement of the DC-8 over its nearly four decades of service to NASA. Besides descriptions of the science accomplished, workshop planners invite discussion of “lessons learned” about operation of a large airborne research laboratory that can be used as NASA moves ahead with furnishing and outfitting the DC-8’s successor, a B-777 that NASA acquired in 2023 in response to a strong recommendation from a 2021 report by the National Academies of Science, Engineering, and Medicine that ESD needed to have such a platform following the retirement of the DC-8 (Airborne Platforms to Advance NASA Earth System Science Priorities: Assessing the Future Need for a Large Aircraft ). Workshop planners are seeking proposals for papers from ESD, related investigator communities—including academia, interagency and international partners, and private sector/non-profit entities—that detail scientific and programmatic results, lessons learned, and personal examples of how the DC-8 advanced science, informed decisions, and provided training opportunities for several generations of NASA. If you wish to present a paper or have questions, please send an abstract of no more than 250 words and a short biography or curriculum vitae, including affiliation by March 31, 2024 to Dr. Brian C. Odom.

NASA/Sam Lott The elements of the super-heavy lift SLS (Space Launch System) rocket for NASA’s Artemis II mission are undergoing final preparations before shipment to NASA’s Kennedy Space Center in Florida for stacking and pre-launch activities in 2024. Teams at NASA’s Marshall Space Flight Center in Huntsville, Alabama, recently rotated the Orion stage adapter– a ring structure that connects NASA’s Orion spacecraft to the SLS rocket’s interim cryogenic propulsion stage (ICPS) – in preparation for the installation of its diaphragm. The installation Nov. 30 marks one of the final steps for the adapter before it is readied for shipment to Kennedy via NASA’s Super Guppy cargo aircraft. “The diaphragm is a composite, dome-shaped structure that isolates the volume above the ICPS from that below Orion,” said Brent Gaddes, lead for the Orion stage adapter, in the Spacecraft/Payload Integration & Evolution Office for the SLS Program at Marshall. “It serves as a barrier between the two, preventing the highly flammable hydrogen gas that could escape the rocket’s propellant tanks from building up beneath the Orion spacecraft and its crew before and during launch.” At five feet tall and weighing in at 1,800 pounds, the adapter is the smallest major element of the SLS rocket that will produce more than 8.8 million pounds of thrust to launch four Artemis astronauts inside Orion around the Moon. The adapter is fully manufactured by engineering teams at Marshall. NASA is working to land the first woman and first person of color on the Moon under Artemis. SLS is part of NASA’s backbone for deep space exploration, along with Orion and the Gateway in orbit around the Moon, and commercial human landing systems. SLS is the only rocket that can send Orion, astronauts, and supplies to the Moon in a single launch.
