Teams with NASA’s Exploration Ground Systems Program began installing the four emergency egress baskets at Launch Pad 39B in preparation for NASA’s Artemis II crewed mission at the agency’s Kennedy Space Center in Florida. In the event of an emergency at the pad during the launch countdown, these baskets, similar to gondolas on ski lifts, will take the astronauts and pad personnel safely from the mobile launcher to the base of the pad where emergency transport vehicles will drive them away. Following installation, teams will thoroughly test the baskets by placing water tanks filled at different levels to help simulate the different weights of the passengers and releasing them. Once the basket testing is complete, teams will perform an emergency egress demonstration with the Artemis II crew to practice the route the astronauts will take during an emergency. The emergency egress system is one of several new systems and upgrades being installed in support of safety for crewed Artemis missions. To see more of the egress basket installations, click here.

Mission Overview jsc2023e066245 (Oct. 15, 2023) — The four SpaceX Crew-8 crew members (from left) Alexander Grebenkin from Roscosmos; Michael Barratt, Matthew Dominick, and Jeanette Epps, all NASA astronauts, are pictured training inside a Dragon mockup crew vehicle at SpaceX headquarters in Hawthorne, California.SpaceX Lifting off from Launch Pad 39A on a Falcon 9 rocket, Dragon will accelerate to approximately 17,500 mph, to dock with the space station. Once in orbit, the crew and SpaceX mission control in Hawthorne, California, will monitor a series of automatic maneuvers that will guide Dragon to the forward-facing port of the station’s Harmony module. The spacecraft is designed to dock autonomously, but the crew can take control and pilot manually, if necessary. After docking, Crew-8 will be welcomed inside the station by the seven-member crew of Expedition 70 and conduct several days of handover activities with the departing astronauts of NASA’s SpaceX Crew-7 mission. After a handover period, NASA astronaut Jasmin Moghbeli, ESA (European Space Agency) astronaut Andy Mogensen, JAXA (Japan Aerospace Exploration Agency) astronaut Satoshi Furukawa, and Roscosmos cosmonaut Konstantin Borisov of Crew-7 will undock from the space station and splash down off the coast of Florida. Crew-8 will conduct new scientific research to prepare for human exploration beyond low Earth orbit and benefit humanity on Earth. Experiments include using stem cells to create organoid models to study degenerative diseases, studying the effects of microgravity and UV radiation on plants at a cellular level, and testing whether wearing pressure cuffs on the legs could prevent fluid shifts and reduce health problems in astronauts. These are just a few of the more than 200 scientific experiments and technology demonstrations taking place during their mission. While aboard the orbiting laboratory, Crew-8 will see the arrival of both the SpaceX Dragon and the Roscosmos Progress cargo spacecraft. Crew-8 also is expected to welcome the agency’s Boeing Crew Flight Test astronauts and the first cargo flight of Sierra Space’s Dream Chaser. A Soyuz spacecraft with three new crew members, including NASA astronaut Tracy Dyson, will also launch during their stay, and the Soyuz carrying NASA astronaut Loral O’Hara will return to Earth. After completing a short handover with Crew-9 at the completion of the mission, Dragon with the four crew members aboard will autonomously undock, depart the space station, and re-enter Earth’s atmosphere. After splashdown off Florida’s coast, a SpaceX recovery vessel will pick up the spacecraft and crew, who then will be helicoptered back to shore. Commercial crew missions enable NASA to maximize use of the space station, where astronauts have lived and worked continuously for more than 23 years testing technologies, performing research, and developing the skills needed to operate future commercial destinations in low Earth orbit, and explore farther from Earth. Research conducted on the space station provides benefits for people on Earth and paves the way for future long-duration trips to the Moon and beyond through NASA’s Artemis missions.

“I have been interested in aviation for as long as I can remember. There are pictures of me at two years old and younger with my face pinned against the window, watching airplanes taxi around the airport. I had never not known that I wanted to be a pilot. The amazing engineering that goes into [airplanes], but certainly the freedom of flight is just spectacular. Being able to see the world from a different perspective is incredible, and getting to fly in space was the culmination of that, seeing the world from an entirely new vantage point. “One thing that surprised me was how emotional the launch piece is, especially for a first-time flier. One, it’s the culmination of these lifehood dreams where it’s taken so long to get here, and you’re finally getting to launch to space, which so few people have the privilege to do. Then, for a long-duration mission, you’re leaving your family and kids behind, and there’s that emotion as well. So, all those things piled up, it just makes for an incredibly special experience, and it’s amazing because eight and a half minutes later, after that engine lights, you’re in space, and you look back on it.” — Bob Hines, Astronaut, NASA’s Johnson Space Center Image Credit: NASA / Kjell Lindgren Interviewer: NASA / Tahira Allen Check out some of our other Faces of NASA.

1 min read Hubble Studies a Sparkling Galaxy Pair This new NASA Hubble Space Telescope image features a pair of interacting galaxies called, NGC 5410 and UGC 8932/PGC 49896. NASA/ESA/D. Bowen (Princeton University)/Processing: Gladys Kober (NASA/Catholic University of America) A pair of small, interacting galaxies shine in this new NASA Hubble Space Telescope image. The larger of the two galaxies is named NGC 5410 and was discovered in 1787 by British astronomer William Herschel. It spans 80,000 light-years across and has a bright white bar of stars at its center. It is also a spiral galaxy with a medium-sized nucleus and spread-out arms. NGC 5410 contains many young, blue star clusters, especially along its arms. The smaller of the two galaxies is called UGC 8932 or PGC 49896 and has a diameter of 60,000 light-years. It has a bright blue bar of stars at its core, indicating that it contains younger stars. Its shape is irregular, likely due to distortions from NGC 5410’s gravitational pull. The pair lies 180 million light-years away in the Canes Venatici constellation and can be seen from the northern hemisphere. Between the two galaxies lies a stream of stars, almost like a bridge, caused by their interaction. Hubble imaged this galaxy in 2023 to examine if interactions between dwarf galaxies create reservoirs of particles that fuel star formation.

1 min read Hubble Views a Galaxy Settling into Old Age The galaxy NGC 3384 takes center stage in this NASA Hubble Space Telescope image. ESA/Hubble & NASA/B. Lehmer et al. NGC 3384, visible in this image, has many of the characteristic features of so-called elliptical galaxies. Such galaxies glow diffusely, are rounded in shape, display few visible features, and rarely show signs of recent star formation. Instead, they are dominated by old, aging, and red-hued stars. This stands in contrast to the liveliness of spiral galaxies such as our home galaxy, the Milky Way, which possess significant populations of young, blue stars in spiral arms swirling around a bright core. However, NGC 3384 also displays a hint of disc-like structure towards its center, in the form of a central ‘bar’ of stars. Many spirals also boast such a bar, the Milky Way included; galactic bars are thought to funnel material through and around a galaxy’s core, which helps maintain and fuel the activities and processes occurring there. NGC 3384 is located approximately 35 million light-years away in the constellation Leo (The Lion). This image was taken using the NASA/ESA Hubble Space Telescope’s Advanced Camera for Surveys.

3 Min Read Landing On Mars: A Tricky Feat! Perseverance Rover’s Entry, Descent and Landing Profile: This illustration shows the events that occur in the final minutes of the nearly seven-month journey that NASA’s Perseverance rover takes to Mars. In honor of Ingenuity’s final flight on The Red Planet, learn from Dave Prosper about what it takes to land on Mars. The Perseverance rover and Ingenuity helicopter landed in Mars’s Jezero crater on February 18, 2021, NASA’s latest mission to explore the red planet. Landing on Mars is an incredibly difficult feat that has challenged engineers for decades: while missions like Curiosity have succeeded, its surface is littered with the wreckage of many failures as well. Why is landing on Mars so difficult? Mars presents a unique problem to potential landers as it possesses a relatively large mass and a thin, but not insubstantial, atmosphere. The atmosphere is thick enough that spacecraft are stuffed inside a streamlined aeroshell sporting a protective heat shield to prevent burning up upon entry – but that same atmosphere is not thick enough to rely on parachutes alone for a safe landing, since they can’t catch sufficient air to slow down quickly enough. This is even worse for larger explorers like Perseverance, weighing in at 2,260 lbs (1,025 kg). Fortunately, engineers have crafted some ingenious landing methods over the decades to allow their spacecraft to survive what is called Entry, Descent, and Landing (EDL). Illustrations of the Entry, Descent, and Landing (EDL) sequences for Viking in 1976, NASA The Viking landers touched down on Mars in 1976 using heat shields, parachutes, and retrorockets. Despite using large parachutes, the large Viking landers fired retrorockets at the end to land at a safe speed. This complex combination has been followed by almost every mission since, but subsequent missions have innovated in the landing segment. The 1997 Mars Pathfinder mission added airbags in conjunction with parachutes and retrorockets to safely bounce its way to a landing on the Martian surface. Then three sturdy “petals” ensured the lander was pushed into an upright position after landing on an ancient floodplain. The Opportunity and Spirit missions used a very similar method to place their rovers on the Martian surface in 2004. Phoenix (2008) and Insight (2018) actually utilized Viking-style landings. Perseverance Rover’s Entry, Descent and Landing Profile: This illustration shows the events that occur in the final minutes of the nearly seven-month journey that NASA’s Perseverance rover takes to Mars. NASA/JPL-Caltech The large and heavy Curiosity rover required extra power at the end to safely land the car-sized rover, and so the daring “Sky Crane” deployment system was successfully used in 2012. After an initial descent using a massive heat shield and parachute, powerful retrorockets finished slowing down the spacecraft to about two miles per hour. The Sky Crane then safely lowered the rover down to the Martian surface using a strong cable. Its job done, the Sky Crane then flew off and crash-landed a safe distance away. Having proved the efficacy of the Sky Crane system, NASA used this same method to attempt a safe landing for Perseverance in February 2021!

NASA’s Northrop Grumman 20th commercial resupply mission will launch atop a SpaceX Falcon 9 rocket to deliver science and supplies to the International Space Station.NASA NASA’s Northrop Grumman 20th commercial resupply mission will launch from Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida. NASA NASA, Northrop Grumman, and SpaceX are targeting 12:29 p.m. EST on Monday, Jan. 29, for the next launch to deliver science investigations, supplies, and equipment to the International Space Station. Filled with more than 7,800 pounds of supplies, the Cygnus cargo spacecraft, carried atop the SpaceX Falcon 9 rocket, will launch from Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida. This launch is the 20th Northrop Grumman commercial resupply services mission to the orbital laboratory for the agency. The backup launch opportunity will be at 12:07 p.m. Tuesday, Jan. 30. Live launch coverage will begin at 12:15 p.m. and air on NASA+, NASA Television, the NASA app, YouTube, and on the agency’s website, with prelaunch events starting Wednesday, Jan. 24. Learn how to stream NASA TV through a variety of platforms Learn more at: nasa.gov/northropgrumman Northrop Grumman S.S. Patricia “Patty” Hilliard Robertson Patricia Robertson was selected as a NASA astronaut in 1998 and scheduled to fly to the International Space Station in 2002, before her untimely death in 2001 from injuries sustained in a private plane crash.NASA Arrival & Departure The Cygnus spacecraft will arrive at the orbiting laboratory at 3:35 a.m. Wednesday, Jan. 31, filled with supplies, hardware, and critical materials to directly support dozens of science and research investigations during Expeditions 70 and 71. NASA astronaut Jasmin Moghbeli will capture Cygnus using the station’s robotic arm, and NASA astronaut Loral O’Hara will act as backup. After capture, the spacecraft will be installed on the Unity module’s Earth-facing port and will spend about six months connected to the orbiting laboratory before departing in May. Cygnus also provides the operational capability to reboost the station’s orbit. After departure, the Kentucky Re-entry Probe Experiment-2 (KREPE-2), stowed inside Cygnus, will take measurements to demonstrate a thermal protection system for spacecraft and their contents during re-entry in Earth’s atmosphere, which can be difficult to replicate in ground simulations. Live coverage of Cygnus’ arrival will begin at 2 a.m., Wednesday, Jan. 31. NASA astronauts Jasmin Moghbeli and Loral O’Hara will be on duty during the Cygnus cargo craft’s aproach and rendezvous. Moghbeli will be at the controls of the Canadarm2 robotic arm ready to capture Cygnus as O’Hara monitors the vehicle’s arrival.NASA Research Highlights Scientific investigations traveling in the Cygnus spacecraft include tests of a 3D metal printer, semiconductor manufacturing, and thermal protection systems for re-entry to Earth’s atmosphere. 3D Printing in Space Samples produced by the Metal 3D Printer prior to launch to the space station.ESA (European Space Agency) An investigation from ESA (European Space Agency), Metal 3D Printer tests additive manufacturing or 3D printing of small metal parts in microgravity. “This investigation provides us with an initial understanding of how such a printer behaves in space,” said Rob Postema of ESA. “A 3D printer can create many shapes, and we plan to print specimens, first to understand how printing in space may differ from printing on Earth and second to see what types of shapes we can print with this technology. In addition, this activity helps show how crew members can work safely and efficiently with printing metal parts in space.” Results could improve understanding of the functionality, performance, and operations of metal 3D printing in space, as well as the quality, strength, and characteristics of the printed parts. Resupply presents a challenge for future long-duration human missions. Crew members could use 3D printing to create parts for maintenance of equipment on future long-duration spaceflight and on the Moon or Mars, reducing the need to pack spare parts or to predict every tool or object that might be needed, saving time and money at launch. Advances in metal 3D printing technology also could benefit potential applications on Earth, including manufacturing engines for the automotive, aeronautical, and maritime industries and creating shelters after natural disasters. Semiconductor Manufacturing in Microgravity The gas supply modules and production module for Redwire’s MSTIC investigation.Redwire Manufacturing of Semiconductors and Thin-Film Integrated Coatings (MSTIC) examines how microgravity affects thin films that have a wide range of uses. This technology could enable autonomous manufacturing to replace the many machines and processes currently used to make a wide range of semiconductors, potentially leading to the development of more efficient and higher-performing electrical devices. Manufacturing semiconductor devices in microgravity also may improve their quality and reduce the materials, equipment, and labor required. On future long-duration missions, this technology could provide the capability to produce components and devices in space, reducing the need for resupply missions from Earth. The technology also has applications for devices that harvest energy and provide power on Earth. Modeling Atmospheric Re-Entry An artist’s rendering of one of the Kentucky Re-entry Probe Experiment-2 (KREPE-2) capsules during re-entry.University of Kentucky Scientists who conduct research on the space station often return their experiments to Earth for additional analysis and study. But the conditions that spacecraft experience during atmospheric reentry, including extreme heat, can have unintended effects on their contents. Thermal protection systems used to shield spacecraft and their contents are based on numerical models that often lack validation from actual flight, which can lead to significant overestimates in the size of system needed and take up valuable space and mass. Kentucky Re-entry Probe Experiment-2 (KREPE-2), part of an effort to improve thermal protection system technology, uses three capsules outfitted with different heat shield materials and a variety of sensors to obtain data on actual reentry conditions. “Building on the success of KREPE-1, we have improved the sensors to gather more measurements and improved the communication system to transmit more data,” said Alexandre Martin, principal investigator at the University of Kentucky. “We have the opportunity to test several heat shields provided by NASA that have never been tested before, and another manufactured entirely at the University of Kentucky, also a first.” The capsules can be outfitted for other atmospheric re-entry experiments, supporting improvements in heat shielding for applications on Earth, such as protecting people and structures from wildfires. Remote Robotic Surgery The surgical robot during testing on the ground before launch.Virtual Incision Corporation Robotic Surgery Tech Demo tests the performance of a small robot that can be remotely controlled from Earth to perform surgical procedures. Researchers plan to compare procedures in microgravity and on Earth to evaluate the effects of microgravity and time delays between space and ground. The robot uses two “hands” to grasp and cut rubber bands, which simulate surgical tissue and provide tension that is used to determine where and how to cut, according to Shane Farritor, chief technology officer at Virtual Incision Corp., developer of the investigation with the University of Nebraska. Longer space missions increase the likelihood that crew members may need surgical procedures, whether simple stiches or an emergency appendectomy. Results from this investigation could support development of robotic systems to perform these procedures. In addition, the availability of a surgeon in rural areas of the country declined nearly a third between 2001 and 2019. Miniaturization and the ability to remotely control the robot help make surgery available anywhere and anytime on Earth. NASA has sponsored research on miniature robots for more than 15 years. In 2006, remotely operated robots performed procedures in the underwater NASA’s Extreme Environment Mission Operations (NEEMO) 9 mission. In 2014, a miniature surgical robot performed simulated surgical tasks on the zero-g parabolic airplane. Growing Cartilage Tissue in Space The Janus Base Nano-matrix anchor cartilage cells (red) and facilitates the formation of the cartilage tissue matrix (green).University of Connecticut Compartment Cartilage Tissue Construct demonstrates two technologies, Janus Base Nano-Matrix and Janus Base Nanopiece. Nano-Matrix is an injectable material that provides a scaffold for formation of cartilage in microgravity, which can serve as a model for studying cartilage diseases. Nanopiece delivers an RNA (ribonucleic acid)-based therapy to combat diseases that cause cartilage degeneration. Cartilage has a limited ability to self-repair and osteoarthritis is a leading cause of disability in older patients on Earth. Microgravity can trigger cartilage degeneration that mimics the progression of aging-related osteoarthritis but happens more quickly, so research in microgravity could lead to faster development of effective therapies. Results from this investigation could advance cartilage regeneration as a treatment for joint damage and diseases on Earth and contribute to development of ways to maintain cartilage health on future missions to the Moon and Mars. Cargo Highlights SpaceX’s Falcon 9 rocket will launch the Northrop Grumman Cygnus spacecraft to the International Space Station NASA’s Northrop Grumman 20th commercial resupply mission will carry 7,805 pounds (3,540 kilograms) of cargo to the International Space Station.NASA Hardware Hydrogen Dome Assembly includes all hydrogen and oxygen electrolysis replacement components within the International Space Station’s Oxygen Generation Assembly. These items are contained in a sub-ambient dome maintained at near vacuum pressure, designed to contain an explosion or fire in the electrolysis cell stack during operation. The dome provides a second barrier to protect against cabin air internal leakage and external leakage into the rack environment, and is pressurized with nitrogen gas for launch. This will launch as an on-orbit spare. Ion Exchange Bed — The ion exchange bed replacement unit consists of a pair of tubes in series containing ion exchange resins, which remove organic acids from the catalytic reactor effluent, and microbial check valve resin, which injects iodine into the water as a biocide agent. This will launch as an on-orbit spare. Catalytic Reactor — The catalytic reactor replacement unit oxidizes volatile organics from the wastewater so they can be removed by the gas separator and ion exchange bed replacement units as part of the station’s water recycling system. This will launch as an on-orbit spare. Biocide Maintenance Canister — The Internal Thermal Control System Coolant Maintenance Assembly is designed to administer o-phthalaldehyde, a biocide used to purify the internal cooling loops in the Destiny laboratory, and the Harmony, Tranquility, Columbus, and Japanese Experiment Modules, to prevent the growth of microorganisms in the thermal control system. This unit will replace the current one installed in the laboratory. Cylinder Flywheel — The ARED (Advanced Resistive Exercise Device) cylinder-flywheel assemblies provide the resistive loads for astronaut anaerobic exercise. The cylinder flywheels impart inertial forces to simulate Earth’s gravity during exercise. International Space Station Roll Out Solar Array Modification Kit 7 – This upgrade kit consists of upper, mid, and lower struts (one each for left and right), a backbone, brackets, and support hardware for the new solar panels. This is the third in series of four modification kits needed to support the installation of the fourth set of upgraded solar arrays. The new arrays are designed to augment the station’s original solar arrays which have degraded over time. The replacement solar arrays are installed on top of existing arrays to provide a net increase in power with each array generating more than 20 kilowatts of power. Urine Processor Assembly Pressure Control and Pump Assembly — The assembly evacuates the urine distillation assembly at startup and periodically purges non-condensable gases and water vapor and pumps them to the separator plumbing assembly. The purge pump housing and pressure control and pump assembly manifolds are liquid cooled to promote steam condensation, thereby reducing the volume of the purge gas. All these systems make up the system used to covert urine to drinking water. Collection Packet and Adapter — Required for minimal, nominal water microbial sampling. In-flight water quality assessment is needed to assure that water of acceptable, defined quality will be available aboard the space station.

Administrator Bill Nelson announces the end of Ingenuity Mars Helicopter

NASA’s history-making Ingenuity Mars Helicopter has ended its mission at the Red Planet after surpassing expectations and making dozens more flights than planned. While the helicopter remains upright and in communication with ground controllers, imagery of its Jan. 18 flight sent to Earth this week indicates one or more of its rotor blades sustained damage during landing, and it is no longer capable of flight. Originally designed as a technology demonstration to perform up to five experimental test flights over 30 days, the first aircraft on another world operated from the Martian surface for almost three years, performed 72 flights, and flew more than 14 times farther than planned while logging more than two hours of total flight time. “The historic journey of Ingenuity, the first aircraft on another planet, has come to end,” said NASA Administrator Bill Nelson. “That remarkable helicopter flew higher and farther than we ever imagined and helped NASA do what we do best – make the impossible, possible. Through missions like Ingenuity, NASA is paving the way for future flight in our solar system and smarter, safer human exploration to Mars and beyond.” NASA to Discuss Ingenuity Mission in Media Call Today In addition to video comments shared from Nelson about the mission’s conclusion, NASA will host a media teleconference at 5 p.m. EST today, Thursday, Jan. 25, to provide an update on Ingenuity Mars Helicopter. Audio of the call will stream live on the agency’s website. Participants in the call are expected to include: Lori Glaze, director, Planetary Science Division, NASA’s Science Mission Directorate at the agency’s headquarters in Washington Laurie Leshin, director, NASA’s Jet Propulsion Laboratory in Southern California Teddy Tzanetos, Ingenuity project manager, NASA JPL Media who wish to participate by phone can request dial-in information by emailing hq-media@mail.nasa.gov. Ingenuity landed on Mars Feb. 18, 2021, attached to the belly of NASA’s Perseverance rover and first lifted off the Martian surface on April 19, proving that powered, controlled flight on Mars was possible. After notching another four flights, it embarked on a new mission as an operations demonstration, serving as an aerial scout for Perseverance scientists and rover drivers. In 2023, the helicopter executed two successful flight tests that further expanded the team’s knowledge of its aerodynamic limits. “At NASA JPL, innovation is at the heart of what we do,” said Leshin. “Ingenuity is an exemplar of the way we push the boundaries of what’s possible every day. I’m incredibly proud of our team behind this historic technological achievement and eager to see what they’ll invent next.” Ingenuity’s team planned for the helicopter to make a short vertical flight on Jan. 18 to determine its location after executing an emergency landing on its previous flight. Data shows that, as planned, the helicopter achieved a maximum altitude of 40 feet (12 meters) and hovered for 4.5 seconds before starting its descent at a velocity of 3.3 feet per second (1 meter per second). However, about 3 feet (1 meter) above the surface, Ingenuity lost contact with the rover, which serves as a communications relay for the rotorcraft. The following day, communications were reestablished and more information about the flight was relayed to ground controllers at NASA JPL. Imagery revealing damage to the rotor blade arrived several days later. The cause of the communications dropout and the helicopter’s orientation at time of touchdown are still being investigated. This enhanced color view of NASA’s Ingenuity Mars Helicopter was generated using data collected by the Mastcam-Z instrument aboard the agency’s Perseverance Mars rover on Aug. 2, 2023, the 871st Martian day, or sol, of the mission. The image was taken a day before the rotorcraft’s 54th flight. After its 72nd flight on Jan. 18, 2024, NASA’s Ingenuity Mars Helicopter captured this color image showing the shadow of one of its rotor blades, which was damaged during touchdown. NASA/JPL-Caltech Triumphs, Challenges Over an extended mission that lasted for almost 1,000 Martian days, more than 33 times longer than originally planned, Ingenuity was upgraded with the ability to autonomously choose landing sites in treacherous terrain, dealt with a dead sensor, cleaned itself after dust storms, operated from 48 different airfields, performed three emergency landings, and survived a frigid Martian winter. Designed to operate in spring, Ingenuity was unable to power its heaters throughout the night during the coldest parts of winter, resulting in the flight computer periodically freezing and resetting. These power “brownouts” required the team to redesign Ingenuity’s winter operations in order to keep flying. With flight operations now concluded, the Ingenuity team will perform final tests on helicopter systems and download the remaining imagery and data in Ingenuity’s onboard memory. The Perseverance rover is currently too far away to attempt to image the helicopter at its final airfield. “It’s humbling Ingenuity not only carries onboard a swatch from the original Wright Flyer, but also this helicopter followed in its footsteps and proved flight is possible on another world,” said Ingenuity’s project manager, Teddy Tzanetos of NASA JPL. “The Mars helicopter would have never flown once, much less 72 times, if it were not for the passion and dedication of the Ingenuity and Perseverance teams. History’s first Mars helicopter will leave behind an indelible mark on the future of space exploration and will inspire fleets of aircraft on Mars – and other worlds – for decades to come.” More About Ingenuity The Ingenuity Mars Helicopter was built by NASA JPL, which also manages the project for NASA Headquarters.

2 min read Hubble Captures a Faint Bridge of Stars This new NASA Hubble Space Telescope image features a member of the galaxy group Arp 295. NASA/ESA/J. Dalcanton (University of Washington)/R. Windhorst (Arizona State University)/Processing: Gladys Kober (NASA/Catholic University of America) One of the galaxies from a galactic group known as Arp 295 is visible in this new NASA Hubble Space Telescope image, along with part of the faint 250,000-light-year-long bridge of stars and gas that stretches between two of the galaxies. The galaxies have passed close enough together that their mutual gravity created this cosmic streamer. When galaxies pass close enough to gravitationally disrupt each other’s shape, they are known as interacting galaxies. This type of interaction happens over billions of years and repeated close passages can result in the merger of the two galaxies. Galactic mergers are thought to be common, and even our own Milky Way is expected to merge with the massive, neighboring Andromeda galaxy in about 4 billion years. Arp 295 is made up of three spiral galaxies designated Arp 295a, Arp 295b, and Arp 295c. Arp 295a is the edge-on galaxy seen in the center of the image, and Arp 295c is the smaller and bluer face-on spiral to its right. Arp 295b is off the top left of this image and not visible here. Together, they are the largest of a loose grouping of galaxies located about 270 million light-years in the direction of the constellation Aquarius.

4 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) NASA pilots along with Sikorsky safety pilots flying Sikorsky’s Black Hawk Optionally Piloted Vehicle, left, and SARA S-76B over Long Island Sound Thursday, Oct. 26, 2023. These flights will allow NASA researchers to test and evaluate multiple Advanced Air Mobility autonomous flight software products designed by NASA.NASA/Steve Freeman In late October, two research helicopters from the manufacturer Sikorsky, a Lockheed Martin company, made a dozen test flights over Long Island Sound, Connecticut taking care to avoid other aircraft in the area around them. Except the ordinary-looking helicopters were flying autonomously – guided by NASA-designed software – and those other aircraft were virtual, part of a simulation to test pilotless flight systems. This was the first time two autonomous aircraft were flying at one another using NASA designed collision avoidance software. The test flights were part of a collaboration by NASA, Sikorsky, and DARPA (Defense Advanced Research Projects Agency). Researchers were able to collect data that will advance completely autonomous flight —systems that can operate an aircraft without a pilot from takeoff to touchdown. The work was part of NASA’s efforts to design and evaluate technologies that could eventually lead to air taxis and other new, automated air transportation options. For the tests, the team used two experimental helicopters adapted for autonomous systems, known as the SARA (Sikorsky Autonomy Research Aircraft) a modified S-76B and the larger OPV (Optionally Piloted Vehicle) Black Hawk. Researchers loaded five NASA-designed software systems into the helicopters, which worked with the automated flight system already integrated by Sikorsky and DARPA. “These flight tests using Sikorsky’s SARA and OPV helicopters show how we can stack technologies together to increase automation over time in a maintainable and scalable way,” says Adam Yingling, NASA project lead. “These efforts demonstrate that we can safely integrate operations to fly the aircraft using several technologies in one navigation tablet.” A NASA and a Sikorsky safety pilot onboard each helicopter supervised the flight tests. Sikorsky’s flight autonomy system, in combination with NASA software, running on tablets the agency designed, allowed the helicopters to fly autonomously along multiple planned routes. The tablets also enabled the safety pilots to monitor flight path options the software selected whenever course corrections needed to occur. The safety pilots observed how the helicopters responded to software-initiated commands, and NASA researchers evaluated how the different software systems worked together to control each aircraft. The tests also assessed how human pilots interacted with the autonomous systems. During the flights, the NASA research pilots were outfitted with specially designed glasses to understand how long they interacted with the navigation tablets and how they physiologically responded to information the tablets provided. Researchers will employ this user experience data to assist in future visual and interactive designs for the software and tablets. The team flew 12 successful flights covering 70 different flight test maneuvers and generating more than 30 flight hours for each aircraft. The NASA collaboration with Sikorsky and DARPA offered a foundation for furthering testing of the automation technology. Virtual flight data is shown from the Dallas-Fort Worth urban area overlaid onto the actual flight test area over the Long Island Sound, near Bridgeport, Connecticut allowing pilots to fly in a mixed reality airspace while testing autonomous software systems.NASA/Stewart Nelson Mixed-Reality Airspace The tests demonstrated the software’s capabilities in a mixed-reality setting. As the SARA and OPV helicopters flew over Long Island Sound, multiple virtual aircraft were added into the same airspace. “For this test, we are using a model of future Advanced Air Mobility airspace with more than 150 virtual aircraft and their flight plans integrated with the flight path management software and the Sikorsky mission manager technology to fly the two helicopters in a mixed-reality mode,” said Mark Ballin, principal investigator for flight path management system development. The NASA-designed software, which commanded both the SARA and OPV helicopters simultaneously, allowed research pilots and engineers to run planned interactions with the virtual aircrafts’ flight plans. The multiple software systems aboard the helicopters worked together, making adjustments to avoid the virtual aircraft and each other. That meant changing altitude, speed, and direction to avoid virtual “collisions” or maintain orbital patterns for landing. This NASA, Sikorsky, and DARPA collaboration will help usher in a new era of autonomy in aviation that could save lives, aircraft, and resources. NASA uses these tests to support the integration of automated systems research that will inform the Federal Aviation Administration with data on flight procedures to help introduce Advanced Air Mobility systems into the national airspace.

5 min read NASA’s Hubble Finds Water Vapor in Small Exoplanet’s Atmosphere This is an artist’s concept of the exoplanet GJ 9827d, the smallest exoplanet where water vapor has been detected in the atmosphere. The planet could be an example of potential planets with water-rich atmospheres elsewhere in our galaxy. With only about twice Earth’s diameter, the planet orbits the red dwarf star GJ 9827. Two inner planets in the system are on the left. The background stars are plotted as they would be seen to the unaided eye looking back toward our Sun. The Sun is too faint to be seen. The blue star at upper right is Regulus; the yellow star at center bottom is Denebola; and the blue star at bottom right is Spica. The constellation Leo is on the left, and Virgo is on the right. Both constellations are distorted from our Earth-bound view from 97 light-years away. NASA/ESA/Leah Hustak (STScI)/Ralf Crawford (STScI) Astronomers using NASA’s Hubble Space Telescope observed the smallest exoplanet where water vapor has been detected in the atmosphere. At only approximately twice Earth’s diameter, the planet GJ 9827d could be an example of potential planets with water-rich atmospheres elsewhere in our galaxy. “This would be the first time that we can directly show through an atmospheric detection, that these planets with water-rich atmospheres can actually exist around other stars,” said team member Björn Benneke of the Trottier Institute for Research on Exoplanets at Université de Montréal. “This is an important step toward determining the prevalence and diversity of atmospheres on rocky planets.” “Water on a planet this small is a landmark discovery,” added co-principal investigator Laura Kreidberg of Max Planck Institute for Astronomy in Heidelberg, Germany. “It pushes closer than ever to characterizing truly Earth-like worlds.” However, it remains too early to tell whether Hubble spectroscopically measured a small amount of water vapor in a puffy hydrogen-rich atmosphere, or if the planet’s atmosphere is mostly made of water, left behind after a primeval hydrogen/helium atmosphere evaporated under stellar radiation. “Our observing program, led by principal investigator Ian Crossfield of Kansas University in Lawrence, Kansas, was designed specifically with the goal to not only detect the molecules in the planet’s atmosphere, but to actually look specifically for water vapor. Either result would be exciting, whether water vapor is dominant or just a tiny species in a hydrogen-dominant atmosphere,” said the science paper’s lead author, Pierre-Alexis Roy of the Trottier Institute for Research on Exoplanets at Université de Montréal. “Until now, we had not been able to directly detect the atmosphere of such a small planet. And we’re slowly getting in this regime now,” added Benneke. “At some point, as we study smaller planets, there must be a transition where there’s no more hydrogen on these small worlds, and they have atmospheres more like Venus (which is dominated by carbon dioxide).” Astronomers using NASA’s Hubble Space Telescope have observed water vapor in the atmosphere of the smallest exoplanet ever detected. Located 97 light-years away, planet GJ 9827d is approximately twice the size of Earth. Credit: NASA’s Goddard Space Flight Center/Lead Producer: Paul Morris Because the planet is as hot as Venus, at 800 degrees Fahrenheit, it definitely would be an inhospitable, steamy world if the atmosphere were predominantly water vapor. At present the team is left with two possibilities. One scenario is that the planet is still clinging to a hydrogen-rich atmosphere laced with water, making it a mini-Neptune. Alternatively, it could be a warmer version of Jupiter’s moon Europa, which has twice as much water as Earth beneath its crust.” The planet GJ 9827d could be half water, half rock. And there would be a lot of water vapor on top of some smaller rocky body,” said Benneke. If the planet has a residual water-rich atmosphere, then it must have formed farther away from its host star, where the temperature is cold and water is available in the form of ice, than its present location. In this scenario, the planet would have then migrated closer to the star and received more radiation. The hydrogen was heated and escaped, or is still in the process of escaping the planet’s weak gravity. The alternative theory is that the planet formed close to the hot star, with a trace of water in its atmosphere. The Hubble program observed the planet during 11 transits – events in which the planet crossed in front of its star – that were spaced out over three years. During transits, starlight is filtered through the planet’s atmosphere and has the spectral fingerprint of water molecules. If there are clouds on the planet, they are low enough in the atmosphere so that they don’t completely hide Hubble’s view of the atmosphere, and Hubble is able to probe water vapor above the clouds. “Observing water is a gateway to finding other things,” said Thomas Greene, astrophysicist at NASA’s Ames Research Center in California’s Silicon Valley. “This Hubble discovery opens the door to future study of these types of planets by NASA’s James Webb Space Telescope. JWST can see much more with additional infrared observations, including carbon-bearing molecules like carbon monoxide, carbon dioxide, and methane. Once we get a total inventory of a planet’s elements, we can compare those to the star it orbits and understand how it was formed.” GJ 9827d was discovered by NASA’s Kepler Space Telescope in 2017. It completes an orbit around a red dwarf star every 6.2 days. The star, GJ 9827, lies 97 light-years from Earth in the constellation Pisces. The Hubble Space Telescope is a project of international cooperation between NASA and ESA. NASA’s Goddard Space Flight Center in Greenbelt, Maryland, manages the telescope. The Space Telescope Science Institute (STScI) in Baltimore, Maryland, conducts Hubble and Webb science operations.

4 min read NASA Collaborating on European-led Gravitational Wave Observatory in Space The LISA (Laser Interferometer Space Antenna) mission, led by ESA (European Space Agency) with NASA contributions, will detect gravitational waves in space using three spacecraft, separated by more than a million miles, flying in a triangular formation. Lasers fired between the satellites, shown in this artist’s concept, will measure how gravitational waves alter their relative distances. AEI/MM/Exozet The first space-based observatory designed to detect gravitational waves has passed a major review and will proceed to the construction of flight hardware. On Jan. 25, ESA (European Space Agency), announced the formal adoption of LISA, the Laser Interferometer Space Antenna, to its mission lineup, with launch slated for the mid-2030s. ESA leads the mission, with NASA serving as a collaborative partner. “In 2015, the ground-based LIGO observatory cracked open the window into gravitational waves, disturbances that sweep across space-time, the fabric of our universe,” said Mark Clampin, director of the Astrophysics Division at NASA Headquarters in Washington. “LISA will give us a panoramic view, allowing us to observe a broad range of sources both within our galaxy and far, far beyond it. We’re proud to be part of this international effort to open new avenues to explore the secrets of the universe.” The LISA mission will enable observations of gravitational waves produced by merging supermassive black holes, seen here in a computer simulation. Most big galaxies contain central black holes weighing millions of times the mass of our Sun. When these galaxies collide, eventually their black holes do too. Download high-resolution video from NASA’s Scientific Visualization Studio. Credit: NASA’s Goddard Space Flight Center/Scott Noble; simulation data, d’Ascoli et al. 2018 NASA will provide several key components of LISA’s instrument suite along with science and engineering support. NASA contributions include lasers, telescopes, and devices to reduce disturbances from electromagnetic charges. LISA will use this equipment as it measures precise distance changes, caused by gravitational waves, over millions of miles in space. ESA will provide the spacecraft and oversee the international team during the development and operation of the mission. Gravitational waves were predicted by Albert Einstein’s general theory of relativity more than a century ago. They are produced by accelerating masses, such as a pair of orbiting black holes. Because these waves remove orbital energy, the distance between the objects gradually shrinks over millions of years, and they ultimately merge. These ripples in the fabric of space went undetected until 2015, when LIGO, the Laser Interferometer Gravitational-Wave Observatory, funded by the U.S. National Science Foundation, measured gravitational waves from the merger of two black holes. This discovery furthered a new field of science called “multimessenger astronomy” in which gravitational waves could be used in conjunction with the other cosmic “messengers” – light and particles – to observe the universe in new ways. Along with other ground-based facilities, LIGO has since observed dozens more black hole mergers, as well as mergers of neutron stars and neutron star-black hole systems. So far, the black holes detected through gravitational waves have been relatively small, with masses of tens to perhaps a hundred times that of our Sun. But scientists think that mergers of much more massive black holes were common when the universe was young, and only a space-based observatory could be sensitive to gravitational waves from them. “LISA is designed to sense low-frequency gravitational waves that instruments on Earth cannot detect,” said Ira Thorpe, the NASA study scientist for the mission at the agency’s Goddard Space Flight Center in Greenbelt, Maryland. “These sources encompass tens of thousands of small binary systems in our own galaxy, as well as massive black holes merging as galaxies collided in the early universe.” Gravitational waves from a simulated population of compact binary systems in our galaxy were used to construct this synthetic map of the entire sky. Such systems contain white dwarfs, neutron stars, or black holes in tight orbits. Maps like this using real data will be possible once the LISA mission becomes active in the next decade. The center of our Milky Way galaxy lies at the center of this all-sky view, with the galactic plane extending across the middle. Brighter spots indicate sources with stronger gravitational signals and lighter colors indicate those with higher frequencies. Larger colored patches show sources whose positions are less well known. NASA’s Goddard Space Flight Center LISA will consist of three spacecraft flying in a vast triangular formation that follows Earth in its orbit around the Sun. Each arm of the triangle stretches 1.6 million miles (2.5 million kilometers). The spacecraft will track internal test masses affected only by gravity. At the same time, they’ll continuously fire lasers to measure their separations to within a span smaller than the size of a helium atom. Gravitational waves from sources throughout the universe will produce oscillations in the lengths of the triangle’s arms, and LISA will capture these changes. The underlying measurement technology was successfully demonstrated in space with ESA’s LISA Pathfinder mission, which operated between 2015 and 2017 and also included NASA participation. The spacecraft demonstrated the exquisite control and precise laser measurements needed for LISA. By Francis Reddy NASA’s Goddard Space Flight Center, Greenbelt, Md.

4 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) As NASA continues to make progress toward sending astronauts to the lunar South Pole region with its Artemis campaign, data from a NASA-funded study is helping scientists better understand this strategic part of the Moon. The study presents evidence that moonquakes and faults generated as the Moon’s interior gradually cools and shrinks are also found near and within some of the areas the agency identified as candidate landing regions for Artemis III, the first Artemis mission planned to have a crewed lunar landing. The epicenter of one of the strongest moonquakes recorded by the Apollo Passive Seismic Experiment was located in the lunar south polar region. However, the exact location of the epicenter could not be accurately determined. A cloud of possible locations (magenta dots and light blue polygon) of the strong shallow moonquake using a relocation algorithm specifically adapted for very sparse seismic networks are distributed near the pole. Blue boxes show locations of proposed Artemis III landing regions. Lobate thrust fault scarps are shown by small red lines. The cloud of epicenter locations encompasses a number of lobate scarps and many of the Artemis III landing regions. NASA/LROC/ASU/Smithsonian Institution “Our modeling suggests that shallow moonquakes capable of producing strong ground shaking in the south polar region are possible from slip events on existing faults or the formation of new thrust faults,” said Tom Watters of the Smithsonian Institution, Washington, lead author of a paper on the research published January 25 in the Planetary Science Journal. “The global distribution of young thrust faults, their potential to be active, and the potential to form new thrust faults from ongoing global contraction should be considered when planning the location and stability of permanent outposts on the Moon.” Lunar Reconnaissance Orbiter Camera (LROC), Narrow Angle Camera (NAC) mosaic of the Wiechert cluster of lobate scarps (left pointing arrows) near the lunar south pole. A thrust fault scarp cut across an approximately 1-kilometer (0.6-mile) diameter degraded crater (right pointing arrow). NASA/LRO/LROC/ASU/Smithsonian Institution The Lunar Reconnaissance Orbiter Camera onboard NASA’s Lunar Reconnaissance Orbiter (LRO) has detected thousands of relatively small, young thrust faults widely distributed in the lunar crust. The scarps are cliff-like landforms that resemble small stair-steps on the lunar surface. They form where contractional forces break the crust and push or thrust it on one side of the fault up and over the other side. The contraction is caused by cooling of the Moon’s still-hot interior and tidal forces exerted by Earth, resulting in global shrinking. The lobate scarps are formed when the lunar crust is pushed together as the Moon contracts. This causes the near-surface materials to break forming a thrust fault. The thrust fault carries crustal materials up and sometimes over adjacent crustal materials. Slip events on existing faults or the formation of new thrust faults trigger shallow moonquakes that can cause strong seismic shaking tens of miles (many tens of kilometers) away from the scarp.Arizona State University/Smithsonian The formation of the faults is accompanied by seismic activity in the form of shallow-depth moonquakes. Such shallow moonquakes were recorded by the Apollo Passive Seismic Network, a series of seismometers deployed by the Apollo astronauts. The strongest recorded shallow moonquake had an epicenter in the south-polar region. One young thrust-fault scarp, located within the de Gerlache Rim 2, an Artemis III candidate landing region, is modeled in the study and shows that the formation of this fault scarp could have been associated with a moonquake of the recorded magnitude. The team also modeled the stability of surface slopes in the lunar south polar region and found that some areas are susceptible to regolith landslides from even light seismic shaking, including areas in some permanently shadowed regions. These areas are of interest due to the resources that might be found there, such as ice. Image shows predicted areas of surface slope instability in the south polar region. Models are for a one-meter-thick (about 3.3-foot) regolith landslide. Blue dots are areas with the least unstable slopes, green dots are moderately unstable slopes, and red dots are most unstable slopes. Image centered on Shackleton crater and the lunar south pole. Locations of proposed Artemis III landing regions are shown by the blue boxes. The model predicts large portions of the interior walls of Shackleton crater are suspectable to landslides (inset) as well as portions of interior crater walls in the Nobile Rim 1 landing region.NASA/LROC/ASU/Smithsonian Institution “To better understand the seismic hazard posed to future human activities on the Moon, we need new seismic data, not just at the South Pole, but globally,” said Renee Weber, a co-author of the paper at NASA’s Marshall Space Flight Center, Huntsville, Alabama. “Missions like the upcoming Farside Seismic Suite will expand upon measurements made during Apollo and add to our knowledge of global seismicity.” “LRO is committed to acquiring data of the lunar surface to aid scientists in understanding important features such as thrust faults,” said LRO Deputy Project Scientist Maria Banks of NASA’s Goddard Space Flight Center in Greenbelt, Maryland, a co-author of the paper. “This study is a good demonstration of one of the many ways in which LRO data is being used to assist planning for our return to the Moon.” This research was funded by NASA’s LRO mission, launched on June 18, 2009. LRO is managed by NASA Goddard for the Science Mission Directorate at NASA Headquarters in Washington. With Artemis missions, NASA is exploring the Moon for scientific discovery, technology advancement, and to learn how to live and work on another world as we prepare for human missions to Mars. We will collaborate with commercial and international partners and establish the first long-term presence on the Moon. NASA will land the first woman and first person of color on the Moon, using innovative technologies to explore more of the lunar surface than ever before.

On Jan. 25, 1984, President Ronald W. Reagan directed NASA to build a permanently inhabited Earth orbiting space station within a decade. The President’s announcement turned years of NASA studies into a real program. As originally envisioned, the modular space station would use the space shuttle for assembly and serve as a microgravity research laboratory and observation platform, a servicing station for satellites, and a staging ground for exploration missions. The President urged NASA to invite its international partners to participate in the program. The complexity and cost of such an outpost resulted in multiple redesigns, with the initial Space Station Freedom ultimately evolving into the International Space Station. On-orbit assembly began in 1998, with permanent human habitation beginning two years later. Left: Wernher von Braun demonstrates a model of his wheel-shaped space station in 1956. Middle: Illustration of one concept of a space base as proposed by the Space Task Group in 1969. Right: The Skylab space station, photographed by the third and final crew after its departure in 1974. As early as the 1950s, American space pioneer Wernher von Braun already had ideas for large orbiting space stations. He envisioned a wheel-shaped facility, slowly rotating to provide artificial gravity to its several thousand occupants. While such an orbital outpost exceeded available technologies for the foreseeable future, shortly after its founding in 1958, NASA began considering more modest space stations. With President John F. Kennedy’s 1961 pronouncement of a Moon landing as a national goal, plans for space stations took a back seat until after NASA achieved that objective. The Space Task Group (STG) that President Richard M. Nixon commissioned in 1969 to assess post-Apollo space objectives proposed an Earth-orbiting space station for the mid-1970s followed later by a much larger space base among several other ambitious projects. Economic realities of the time precluded such lofty goals; President Nixon approved the space shuttle in 1972, the only STG-recommended project to receive funding. Approval of an American space station awaited a later president. In the meantime, the highly successful experimental Skylab space station, based on Apollo hardware, housed three successive crews of three astronauts each, for 28, 59, and 84 days, in 1973 and 1974.

During his Jan. 25, 1984, State of the Union address to a joint session of Congress, President Reagan directed NASA to develop a “permanently manned space station and to do it within a decade.” His comments reflected his view of American pre-eminence in space, but also explicitly stated that the United States would invite other nations to join in the project. President Reagan spelled out the benefits to be derived from such an orbiting platform: Our progress in space—taking giant steps for all mankind—is a tribute to American teamwork and excellence. Our finest minds in government, industry, and academia have all pulled together. And we can be proud to say: We are first; we are the best; and we are so because we’re free. America has always been greatest when we dared to be great. We can reach for greatness again. We can follow our dreams to distant stars, living and working in space for peaceful, economic, and scientific gain. … A space station will permit quantum leaps in our research in science, communications, in metals, and in lifesaving medicines which could be manufactured only in space. We want our friends to help us meet these challenges and share in their benefits. NASA will invite other countries to participate so we can strengthen peace, build prosperity, and expand freedom for all who share our goals. In response to President Reagan’s direction, NASA Administrator James M. Beggs said, “The space program is alive and well, and we have a new initiative. … The space station will give us a permanent presence in low Earth orbit … and will be the cornerstone of our activities in space through the end of the century and beyond.” He added that the President’s initiatives, “are the right ones for the right time in our history.” In the optimism that followed President Reagan’s announcement, NASA laid out an ambitious plan for a space station composed of three separate orbital platforms to conduct microgravity research as well as Earth and celestial observations, to serve as a transportation and servicing node for space vehicles and satellites, and to stage missions for deep-space exploration. NASA signed agreements with the European Space Agency (ESA) and Japan’s National Space Development Agency (NASDA), now the Japan Aerospace Exploration Agency (JAXA), to provide their own research modules. Canada agreed to provide a robotic servicing system. In April 1985, NASA established a Space Station Program Office at the Johnson Space Center in Houston. Assessments of the original “Dual Keel” design determined that it was overly complex to build and cost estimates for the ambitious space station continued to rise. Over the next several years, engineers and managers redesigned the facility and simplified it to a single-truss configuration with the pressurized modules clustered near the core and the solar arrays for power generation at the ends of the truss. In July 1988, President Reagan announced that the orbital facility would be called Space Station Freedom, and two months later the Unites States, Japan, Canada and nine ESA member states signed an Inter-Governmental Agreement (IGA) for its construction and utilization. The redesigned facility would focus on microgravity research. Left: Model of the Space Station showing the proposed dual keel configuration (1985). Middle: Illustration of Space Station Freedom by Alan Chinchar (1991). Right: Russian space station Mir photographed from Space Shuttle Discovery during the STS-91 mission (1998). Space Station Freedom underwent several more redesigns to keep it cost-effective. In the meantime, the Soviet Union operated its Mir space station beginning with the launch of its first module in 1986. Over the years, the Soviets added several elements to increase the facility’s research and habitation capabilities. With the collapse of the Soviet Union in 1991, the future of Mir and its planned Mir-2 successor faced uncertainty in the new cash-strapped Russia. To take advantage of its extensive experience with operating space stations and keeping crews on orbit for up to a year, in 1993 President William J. “Bill” Clinton invited Russia to join the space station program as a full partner, essentially adding modules planned for Mir-2 to U.S., European, Japanese, and Canadian elements from Space Station Freedom. The new outpost would be called the International Space Station. In preparation for space station operations, between 1995 and 1998, seven American astronauts joined Russian cosmonauts as long-duration residents aboard Mir, with space shuttles providing transportation and resupply logistics. On Jan. 29, 1998, representatives from the United States, Russia, Japan, Canada and 11 participating ESA countries met at the U.S. State Department in Washington, D.C., and signed an updated IGA on Space Station Cooperation. The new IGA established the overall cooperative framework for the design, development, operation, and utilization of the space station and addressed several legal topics, including civil and criminal jurisdiction, intellectual property, and the operational responsibilities of the partners.

Ten months after the signing of the 1998 IGA, on-orbit construction of the space station began during the STS-88 mission, with the joining of the first two elements, the Zarya and Unity modules. The first expedition crew of NASA astronaut William M. Shepherd and Russian Space Agency, now Roscosmos, cosmonauts Yuri P. Gidzenko and Sergei K. Krikalev arrived to take up residence aboard the station on Nov. 2, 2000. More than 23 years later, multinational crews continue to live and work aboard a much enlarged and permanently inhabited space station, a unique microgravity laboratory for conducting research in a wide variety of scientific disciplines and a testbed for future human exploration programs.

23 Min Read The Marshall Star for January 24, 2024 NASA’s IXPE Team Awarded Prestigious Rossi Prize By Rick Smith NASA’s IXPE (Imaging X-ray Polarimetry Explorer) team has been awarded a top prize in high-energy astronomy. The High Energy Astrophysics Division of the American Astronomical Society (AAS) has awarded the 2024 Bruno Rossi Prize to retired NASA astrophysicist Martin Weisskopf, Italian Space Agency principal investigator Paolo Soffitta, and their team for development of IXPE, “whose novel measurements advance our understanding of particle acceleration and emission from astrophysical shocks, black holes and neutron stars,” according to the AAS announcement. NASA’s Imaging X-ray Polarimetry Explorer mission, led by retired NASA astrophysicist Martin Weisskopf, left, and Italian Space Agency principal investigator Paolo Soffitta, has received the 2024 Rossi Prize in high-energy astronomy, awarded annually by the American Astronomical Society. NASA/INAF “IXPE is a realization of decades of work and belief in the importance of X-ray polarization measurements for X-ray astronomy. I am honored and excited to share this prize with Paolo Soffitta and the entire IXPE team,” said Weisskopf, who was IXPE’s principal investigator during its development. He retired from NASA in 2022. “IXPE is the demonstration of how an idea pursued for more than 30 years has been transformed into a successful mission, thanks to the collaboration between the United States and Italy,” Soffitta said. “It’s incredible to receive this prize along with Martin Weisskopf and on behalf of so many people whose expertise and enthusiasm have made this breakthrough in astrophysics possible.” Developed by NASA, the Italian Space Agency, and partners in a dozen countries, IXPE was launched to space on Dec. 9, 2021. Today, it orbits Earth some 340 miles up to observe X-ray emissions from powerful cosmic phenomena hundreds or thousands of light-years away. In 2023 alone, its subjects of study included blazars such as Markarian 501 and Markarian 421, supernova remnants including Tycho and SN 1006, and the supermassive black hole at the center of our own galaxy. Its success led NASA to formally extend the mission for an additional 20 months, through at least September 2025. An artist’s illustration of the IXPE spacecraft in orbit, studying high-energy phenomena light-years from Earth.NASA “We at NASA are incredibly proud of Dr. Weisskopf and the IXPE team around the world,” said acting Marshall Center Director Joseph Pelfrey. “IXPE allows us to look at the universe through a vantage point never seen before. It’s particularly gratifying to continue Marshall’s long association with the Rossi Prize, which identifies singular breakthroughs and unprecedented innovation in high-energy astrophysics – a field in which our researchers excel.” Weisskopf, together with Harvard astrophysicist Harvey Tananbaum, previously received the Rossi Prize in 2004 for their work to develop and fly NASA’s Chandra X-ray Observatory, which continues to study X-ray phenomena across the cosmos. Marshall researchers Gerald Fishman and Colleen Wilson-Hodge also were awarded the Rossi Prize in 1994 and 2018, respectively. Fishman was honored for his contributions to the Compton Gamma-ray Observatory’s BATSE (Burst and Transient Source Experiment) mission, Wilson-Hodge for her work with the Fermi GBM (Gamma-ray Burst Monitor) in August 2017, detecting gravitational and light waves from the spectacular smashup of two neutron stars in a distant galaxy. The Rossi Prize is awarded annually for a significant recent contribution to high-energy astrophysics. The honor includes an engraved certificate and a $1,500 award.

Alvarez and Reynolds don’t have a traditional mentorship. Both began in Marshall’s propulsion systems department in 2004. While Alvarez is younger than Reynolds, Alvarez is mentoring Reynolds. Alvarez may not have decades more experience than Reynolds, but Alvarez joining the SES (Senior Executive Service) coincided with Reynolds wanting to transition to the SES. Their shared working experience and similar goal made a perfect fit for their mentorship. Reynolds is currently being mentored by Alvarez in preparation for a Senior Executive Service position.NASA Hoping their experience can help others during National Mentoring Month, they discussed their insight about finding the right type of mentorship. Question: What does mentorship mean to you? Reynolds: Mentorship is an outside perspective that benefits me by providing a better solution. You can ask your mentor about your ideas to self-examine the path that you’re on. They know you and have your best interest in mind. Your decisions are not directly going to affect them, so they can offer candid advice. Alvarez: For me, mentorship is worth the time investment because we can get stuck in our day-to-day routine. It’s a refreshing time during the week to sit down with someone knowing what they’re experiencing and helping them, so they don’t have to navigate certain challenges on their own. I have templates, articles, rubrics, books, and other perspectives I gained through my first year in SES. Now I can offer those resources. It’s something that I want to pass on to somebody else because it takes a village to do this. Mentoring is very energizing and fruitful. It reminds me that I love NASA and it’s a great place to work. I hope that I can provide that feeling and energy to someone else and it just keeps going. Question: What impact has mentorship had on you and your career? Alvarez: With Dave and I starting from the same department, we had some of the same mentors early on. Mentors give you confidence to move to the next role when you’re down in the details, doing the work, and years into a position. I would also say I was fortunate enough to have a great mentor that was outside of my department. The most important trait she gave to me was resiliency. There are many times when you go for something and are unsuccessful. Having somebody that believes in you during those times is huge. Reynolds: My first formal mentor was assigned to me while I was in the Mid-Level Leadership Program and she was in SES at NASA’s Glenn Research Center. She encouraged me to get out of engineering, because she believed I was ready for a leadership role. Without her, I wouldn’t have transitioned as quickly as I did. My current mentorship is also kicking me to the next level and informing me of all the options I need to consider. Having a mentor that has known you for a long time, like Alvarez, is beneficial. You can trust their guidance more because they’ve seen you fail, and they still believe in your success. Question: What was the initial goal and how has that impacted the type of mentoring relationship you built? Reynolds: The initial goal was Alvarez prepping me to become SES qualified and she’s helped me at every step. Alvarez encouraged me to apply for the ASPIRE program. Programs and tools like that are exactly what I need to know about. She’s provided a lot of information that I didn’t know I would need to consider. A young Alvarez, third from left, and Reynolds, far right, smile for a photo taken while they were both working in the propulsion systems department at Marshall.NASA Alvarez: I mentor a lot of people at different levels. Reynolds is a unique mentee because he is seeking out a big goal. Other mentees coming to me are in different stages, or they’re in a similar field and want to discuss the type of work I do. His goal is personal. I don’t want Reynolds to feel unprepared. I want him to go into his interview and any future roles with confidence and his best foot forward. I want Dave’s future peers to know he’s ready to lead. If Dave is successful in achieving his goal, I want to help him through that transition during the first year of his new role as well, especially with the person who last had the position being gone. I have executive mentors who are the only people I can discuss certain topics with. A part of the goal is Reynolds’ long-term success, which is why it’s important for him to have access to that network of people. If Reynolds needs help with something I’m not well-versed in, I can get him in contact with someone who is. Question: How do you think the dynamic between mentor and mentee may differ in a formal mentoring relationship compared to an informal, casual mentoringencounter? Reynolds: Formal mentoring relationships are more deliberate. We have a goal that we set. We’re not just having lunch, we set a scheduled time where we each have ideas we bring to discuss. Formal encounters are more structured. With informal mentorships you can also have casual lunches where good advice is thrown back and forth, but I have noticed if you’re more deliberate, you’ll get concrete progress. Alvarez: Dave having a specific objective made the mentorship formal. The structure provided time for me to gather materials I found helpful in preparation for SES. With a hands-on approach, I could help Reynolds during his time in the ASPIRE program. We methodically planned how to reach each goal and in turn the objective. As we’re doing the work, we’re checking in consistently. Informal mentorships are hard. There’s no set amount of time spent together, and its disorganization makes it easier to lose momentum toward the objective. Informal mentorships also make it harder to feel a sense of accomplishment because progress is harder to assess. Question: What advice do you have for someone else considering finding or being a mentor? Alvarez: Think outside the box. Some people come in with an unconscious bias of what a mentor is. Mentees can become overly concerned with a mentor’s background. Not knowing their background is a good thing. Remain open minded about what someone else can offer you. You’re always going to get some good nuggets out of a mentorship. If someone suggests a mentor to you, take it. They might see something that neither of you do that would make a great pairing. I also recommend that some people choose mentors with a different career path like Dave and me. We shared the same foundation but then we went off in two different branches. Getting to combine those different insights is amazing because it makes us stronger. Reynolds: As a mentee, check that you have humility. It’d be easy for me to dismiss Alvarez as a mentor because of our similarities. I recognize, she’s had a completely different life and is therefore capable of giving me an outside perspective. She’s also wicked smart, and I listen to wicked smart people. I’ve heard people reject advice from others because they are on the same tier or below career wise. That’s not a good approach. Ask yourself who can help with growth as opposed to finding somebody that that will help you up the ladder. Editor’s note: This is the second in a Marshall Star series during National Mentoring Month in January. Marshall team members can learn more about the benefits of mentoring on Inside Marshall.

He will fill the role until a permanent director is named as well as continuing his duties as Marshall’s associate director, technical. Larry Leopard, Marshall’s associate director, technical, has been named acting director of NASA Marshall Space Flight Center’s Engineering Directorate.NASA As Marshall’s associate director, technical, Leopard provides expert advice in all facets of the center’s responsibilities by conducting special studies; provides authoritative advice and assistance in policy review; manages and reports on centerwide and directorate metrics; and develops benchmark strategies. He was appointed to the position in December 2020. Leopard previously served as director of the Engineering Directorate from 2018 to 2020. Lisa Bates will remain as deputy director of Marshall’s Engineering Directorate.NASA Lisa Bates will remain as deputy director and will be responsible for the day-to-day management of the Engineering Directorate. › Back to Top I Am Artemis: Erick Holsonback Whether he’s advising student robotic competitions or managing production of a powerful, new Moon rocket stage, Erick Holsonback meets technical challenges with enthusiasm. Holsonback, a Jacobs Technology employee, is subsystem manager for production and launch operations of the exploration upper stage (EUS) for NASA’s SLS (Space Launch System) rocket. SLS is NASA’s super heavy lift rocket that will launch the agency’s Artemis campaign to the Moon. The exploration upper stage is one of two upgrades to the SLS rocket as it evolves to the Block 1B variant for missions beginning with Artemis IV. Along with the rocket’s new universal stage adapter, the SLS rocket in its Block 1B configuration will be able to send 40% more payload to the Moon in a single launch. Eric Holsonback, a Jacobs Technology employee, is subsystem manager for production and launch operations of the exploration upper stage for NASA’s SLS (Space Launch System) rocket.NASA/Michael DeMocker Holsonback’s job stretches from setting up production for the future upper stage at NASA’s Michoud Assembly Facility, where it’s built, to preparing it for launch from the agency’s Kennedy Space Center. “It’s exciting to be part of a capability that will send more crew and cargo to the Moon in a single launch than any other current rocket,” Holsonback said. “That’s going to make operations in the challenging space environment a lot simpler.” Growing up in North Georgia, Holsonback remembers wanting to be an astronaut and turning street cars into hot rods. He figured he’d wind up in the auto industry, until Pratt & Whitney offered him a job working on space shuttle main engine turbomachinery straight out of college in 1997. He briefly left the space business but jumped at a chance to get back in with the SLS Program in 2016 at NASA’s Marshall Space Flight Center. “I wanted to come back and do rockets,” he recalled. “It gets in your blood. You’re part of something bigger that just yourself. Through Artemis, we are truly impacting the space program at its foundational level of how we are getting back to the Moon and to Mars.” Holsonback’s enthusiasm for space challenges doesn’t end at the office door. In his free time, Holsonback has mentored and coached his two daughters’ technology challenge competitions. While the challenge is foremost a robotics contest, Holsonback is proud of the lessons in problem solving, technology, and project management he’s helped impart to the team along the way – which he likens to his NASA job. You could say Erick Holsonback is working on the future personally as well as professionally, but it’s hard to beat working on a Moon rocket. “I’ve had some great opportunities with NASA, but my current role is pretty amazing – getting to be part of building and launching,” he reflected. “I get to play a little part in the overall foundation work that is going to be part of the history of our country for years to come.” 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 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. › Back to Top Mission Success is in Our Hands: Greg Drayer By Wayne Smith Mission Success is in Our Hands is a safety initiative collaboration between NASA’s Marshall Space Flight Center and Jacobs. As part of the initiative, eight Marshall team members are featured in new testimonial banners placed around the center. This is the third in a Marshall Star series profiling team members featured in the testimonial banners. Greg Drayer is the JSEG (Jacobs Space Exploration Group) team lead for EV74, the Systems Analysis Branch, working at NASA’s Marshall Space Flight Center. He is also the JSEG Tech Fellow for Modeling and Simulation. Greg Drayer is the JSEG (Jacobs Space Exploration Group) team lead for EV74, the Systems Analysis Branch, working at NASA’s Marshall Space Flight Center. NASA/Charles Beason He previously was a Modeling and Simulation integration systems engineer, representing NASA’s SLS (Space Launch System) Program to the Data Integration Integrated Task Team and supporting the certification of Design Math Models. He started working at Marshall in 2020. A native of Caracas, Venezuela, Drayer is a graduate of both Universidad Simon Bolivar, where he earned a bachelor’s degree in electrical engineering and magister in systems engineering, and the Georgia Institute of Technology, where he earned his doctorate with the School of Electrical and Computer Engineering. He was sponsored by the U.S. Department of State International Fulbright Science and Technology Program. Question: What are some of your key responsibilities? Drayer: I am responsible for the proactive management of the EV74 Branch JSEG Task Order and Systems Evaluation personnel to ensure the safe and effective accomplishment of Marshall requirements by providing engineering, scientific, and technical support to various NASA programs. My team is a high-performing group of three different sub-teams executing challenging tasks for Marshall’s Systems Engineering and Integration Division (EV70) in support of SLS, HLS (Human Landing System), and MAV (Mars Ascent Vehicle) programs, providing unique expertise in the following domains: Program compliance with the NASA Standard for Models and Simulations, NASA-STD-7009. Vehicle mass properties and weight management. SLS photogrammetric imaging and analysis. Data integration tools, systems, and processes. Adoption of model-based systems engineering methodologies. Question: How does your work support the safety and success of NASA and Marshall missions? Drayer: The goal of our Modeling and Simulation Sub-Team at NASA is to help reduce the risks associated with models and simulations-influenced decisions by properly conveying the credibility of results to those making critical decisions in support of program compliance with NASA-STD-7009, Standard for Models and Simulations. We ensure the NASA’s commitment to excellence in satisfying the requirements of NASA-STD-7009, an outcome resulting from the Columbia Accident Investigation Board Report. Question: What does the Mission Success is in Our Hands initiative mean to you? Drayer: Working in support of NASA-STD-7009, this initiative hits close to home as another reminder of why we do our work the way we are required. Beyond any statistics, to me this campaign is a reminder and a challenge to ensure that we ‘Know what we build. Test what we build. Test what we fly. Test like we fly.’ We should continue learning from our past to make sure that it does not repeat in the future. This initiative helps us dedicate the time to remember why we do things the way we do them, and how we arrived at today’s NASA culture. Question: Do you have a story or personal experience you can share that might help others understand the significance of mission assurance or flight safety? Drayer: Coming back from COVID-19 has been a great challenge to overcome. Incredibly, we all have found some strange comfort zones from which we are now needing to come back to collaborate better. I know how much some of us value our ability to telework at times. However, I would like us all to also understand how some in-person conversations can save us many if not several hours of unending electronic communications. I would like all of us to demonstrate to ourselves why we truly need to be present in our meetings and engage as best as we can to reap the fruit of those interactions. Let us lead by example and ‘preach’ about it along the way with our actions, to the benefit of the NASA culture in a post-COVID era. As an agency, this can greatly impact our ability to ensure mission success and flight safety. Question: How can we work together better to achieve mission success? Drayer: We go all the way to the Moon in search of discoveries, science, and developing new technologies. And even beyond all these, we go to the Moon to find ourselves personally and each other. That journey has begun already with each weekday and at times weekends that we dedicate to work with the mission in mind, working hard to meet and exceed the expectations of our customers and our stakeholders, most important of which are our astronauts and their families.

Data collected from the test series will be used to certify production of new RS-25 engines by lead contractor Aerojet Rocketdyne, an L3Harris Technologies company, to help power the SLS rocket on future Artemis missions to the Moon and beyond, beginning with Artemis V. NASA’s Marshall Space Flight Center manages the SLS Program. NASA completed a full-duration, 500-second hot fire of an RS-25 certification engine Jan. 17, continuing a critical test series to support future SLS (Space Launch System) missions to the Moon and beyond as NASA explores the secrets of the universe for the benefit of all.NASA/Danny Nowlin Teams are evaluating the performance of several new engine components, including a nozzle, hydraulic actuators, flex ducts, and turbopumps. The current series is the second and final series to certify production of the upgraded engines. NASA completed an initial 12-test certification series with the upgraded components in June 2023. During the Jan. 17 test, operators followed a “test like you fly” approach, firing the engine for the same amount of time – almost eight-and-a-half minutes (500 seconds) – needed to launch SLS and at power levels ranging between 80% to 113%. The Jan. 17 test comes three months after the current series began in October. During three tests last fall, operators fired the engine for durations from 500 to 650 seconds. The longest planned test of the series occurred on Nov. 29 when crews gimbaled, or steered, the engine during an almost 11-minute (650 seconds) hot fire. The gimbaling technique is used to control and stabilize SLS as it reaches orbit. Each SLS flight is powered by four RS-25 engines, firing simultaneously during launch and ascent to generate over 2 million pounds of thrust. The first four Artemis missions with SLS are using modified space shuttle main engines that can power up to 109% of their rated level. The newly produced RS-25 engines will power up to the 111% level to provide additional thrust. Testing to the 113% power level provides an added margin of operational safety. With the completion of the test campaign in 2024, all systems are expected to be “go” for production of 24 new RS-25 engines for missions beginning with Artemis V. Through Artemis, NASA will establish a long-term presence at the Moon for scientific exploration with commercial and international partners, learn how to live and work away from home, and prepare for future human exploration of Mars. › Back to Top Station Crew Assists Ax-3 on Advanced Space Research The Expedition 70 crew spent Jan. 23 on a host of research activities and spacesuit maintenance while assisting their Axiom Mission 3 (Ax-3) guests on the International Space Station. The four Ax-3 crew members had their hands full as they explored cancer research, space botany, and robotics for Earth and space benefits. The Ax-3 crew arrived Jan. 20. Astronauts Andreas Mogensen, Loral O’Hara, and Satoshi Furukawa dedicated part of their schedule to the Ax-3 mission. The trio helped the four private astronauts get up to speed with life on orbit as well as conduct advanced microgravity science. The four Axiom Mission 3 astronauts, front row, and the seven Expedition 70 crew members wave to the camera following a crew greeting ceremony on the International Space Station on Jan. 20. NASA TV Mogensen from ESA (European Space Agency) spent a couple of hours ensuring the Ax-3 crewmates are familiarized with systems throughout the orbital lab. O’Hara from NASA set up the LSG (Life Science Glovebox) for an Ax-3 space botany investigation while Furukawa from JAXA (Japan Aerospace Exploration) activated a microscope to look at cell samples for an Ax-3 cancer study. Ax-3 Commander Michael López-Alegría and Mission Specialist Alper Gezeravcı worked in the Kibo laboratory module’s LSG and tested the genetic editing of space-grown plants. Results may enable genetic modifications allowing plants to adapt to weightlessness and promote crew health. Ax-3 Pilot Walter Villadei peered at cell samples inside the Kermit microscope to learn how to predict and prevent cancer both on Earth and in space. Ax-3 Mission Specialist Marcus Wandt tested the ability to remotely control robots on Earth from the space station. Working in the Columbus laboratory module, Wandt used a laptop computer to command a team of Earth-bound robots simulating a robotic exploration mission on another planet controlled from a spacecraft. Mogensen would go on to organize food packs, charge virtual reality hardware for a mental health study, then videotape a space physics demonstration for junior high school students. Furukawa serviced science freezers and combustion research gear before cleaning vents inside the Unity module. Furukawa wrapped up his day with eye checks with NASA Flight Engineer Jasmin Moghbeli. O’Hara operated the medical imaging gear examining the optic nerve, retina, and cornea of both astronauts. Moghbeli earlier installed and tested a camera and lights on a spacesuit helmet. The orbiting lab’s three cosmonauts from Roscosmos focused on operations in their segment. Veteran Flight Engineer Oleg Kononenko spent his day inspecting the Zvezda service module and servicing communication and computer systems in the Nauka science module. Flight Engineer Nikolai Chub photographed the condition of Zvezda’s windows then studied how microgravity conditions such as magnetic and electrical fields affect fluid physics. Flight Engineer Konstantin Borisov deactivated Earth observation gear, downloaded vibration data the station experiences while orbiting Earth, then worked on orbital plumbing duties. The Payload Operations Integration Center at NASA’s Marshall Space Flight Center operates, plans, and coordinates the science experiments onboard the space station 365 days a year, 24 hours a day.

On Jan. 10, they successfully removed two stubborn fasteners that had prevented the final steps of opening the TAGSAM (Touch-and-Go-Sample-Acquisition-Mechanism) head. A top-down view of the OSIRIS-REx Touch-and-Go-Sample-Acquisition-Mechanism head with the lid removed, revealing the remainder of the asteroid sample inside.NASA/Erika Blumenfeld & Joseph Aebersold Erika Blumenfeld, creative lead for AIVA (Advanced Imaging and Visualization of Astromaterials) and Joe Aebersold, AIVA project lead, captured a photograph of the open TAGSAM head including the asteroid material inside using manual high-resolution precision photography and a semi-automated focus stacking procedure. The result is an image that shows extreme detail of the sample. Next, the curation team will remove the round metal collar and prepare the glovebox to transfer the remaining sample from the TAGSAM head into pie-wedge sample trays. These trays will be photographed before the sample is weighed, packaged, and stored at Johnson, home to the most extensive collection of astromaterials in the world. The remaining sample material includes dust and rocks up to about 0.4 inch in size. The final mass of the sample will be determined in the coming weeks. The curation team members had already collected 2.48 ounces of asteroid material from the sample hardware before the lid was removed, surpassing the agency’s goal of bringing at least 2.12 ounces to Earth. The curation team will release a catalog of all the Bennu samples later this year, which will allow scientists and institutions around the world to submit requests for research or display. OSIRIS-REx is the third mission in NASA’s New Frontiers Program, managed by the agency’s Marshall Space Flight Center. › Back to Top View the full article

NASA/JPL-Caltech NASA’s twin rovers, Spirit and Opportunity, stand on the Martian landscape in this poster created to commemorate their 20th landing anniversary. The rovers landed in January 2004, on opposite sides of the planet in locales that scientists suspected had been affected by liquid water in the past. Their main scientific objective was to search for a range of rocks and soil types and then look for clues for past water activity on Mars—and what they found rewrote textbooks. In addition to proving that water once existed on Mars, the rovers also far exceeded their initial planned lifetimes. Spirit operated for 6 years, 2 months, and 19 days, more than 25 times its original intended lifetime, and Opportunity operated for almost 15 years, setting several records.

Credits: Nathan De Fortunato During a ceremony at the Museum of Fine Arts in Brussels on Tuesday, Belgium became the 34th country to sign the Artemis Accords. The accords establish a practical set of principles to guide space exploration cooperation among nations, including those participating in NASA’s Artemis campaign. “Congratulations to Belgium on becoming the newest member of the Artemis Accords family,” said NASA Administrator Bill Nelson. “It’s clear that countries around the world understand the opportunity that space presents. As the 34th signatory of the Artemis Accords, Belgium is showing great leadership in committing to responsible exploration in the 21st century.” Hadja Lahbib, minister of foreign affairs, European affairs and foreign trade, and the federal cultural institutions, and Thomas Dermine, state secretary for economic recovery and strategic investments, in charge of science policy, signed on behalf of Belgium. “Joining the Artemis Accords reflects our logic of cooperation and enables Belgium to join the working group of states that have already signed,” said Dermine. “Belgium always has its feet on the ground and its head in the stars,” said Lahbib. “Our country is one of the world leaders in space exploration. The signing of the Artemis Accords shows our ongoing commitment to sustainable and responsible space, and will strengthen ties with international partners. It will also open new economic opportunities for our companies, which have world-renowned expertise in the space sector.” NASA, in coordination with the U.S. Department of State, established the Artemis Accords in 2020 together with seven other original signatories. Since then, the Accords signatories have held focused discussions on how best to implement the Artemis Accords principles. The Artemis Accords reinforce and implement key obligations in the 1967 Outer Space Treaty. They also strengthen the commitment by the United States and signatory nations to the Registration Convention, the Rescue and Return Agreement, as well as best practices and norms of responsible behavior NASA and its partners have supported, including the public release of scientific data. More countries are expected to sign the accords in the months and years ahead, which is important to advancing safe, peaceful, and prosperous activities in space.

4 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) This map shows the location where the small asteroid 2024 BX1 harmlessly impacted Earth’s atmosphere over Germany, about 37 miles (60 kilometers) west of Berlin, on Jan. 21. A NASA system called Scout predicted the impact time and site within 1 second and about 330 feet (100 meters).NASA/JPL-Caltech The Scout impact assessment system calculated where and when the asteroid 2024 BX1 would impact Earth’s atmosphere, providing a useful demonstration of planetary defense capability. A small asteroid about 3 feet (1 meter) in size disintegrated harmlessly over Germany on Sunday, Jan. 21, at 1:32 a.m. local time (CET). At 95 minutes before it impacted Earth’s atmosphere, NASA’s Scout impact hazard assessment system, which monitors data on potential asteroid discoveries, gave advance warning as to where and when the asteroid would impact. This is the eighth time in history that a small Earth-bound asteroid has been detected while still in space, before entering and disintegrating in our atmosphere. The asteroid’s impact produced a bright fireball, or bolide, which was seen from as far away as the Czech Republic and may have scattered small meteorites on the ground at the impact site about 37 miles (60 kilometers) west of Berlin. The asteroid was later designated 2024 BX1. Explore the 3D of asteroids, comets, and near-Earth objects While NASA reports on near-Earth objects (NEOs) of all sizes, the agency has been tasked by Congress with detecting and tracking NEOs 140 meters in size and larger that could cause significant damage on the ground if they should impact our planet. Those objects can be spotted much further in advance than small ones like 2024 BX1. Tiny asteroids like this one impact our planet from time to time. They pose no hazard to life on Earth but can provide a useful demonstration of NASA’s planetary defense capabilities such as Scout’s rapid-response trajectory computation and impact alerts. How It Was Predicted The asteroid 2024 BX1 was first observed less than three hours before its impact by Krisztián Sárneczky at Piszkéstető Mountain Station of the Konkoly Observatory near Budapest, Hungary. These early observations were reported to the Minor Planet Center – the internationally recognized clearinghouse for the position measurements of small solar system bodies – and automatically posted on the center’s Near-Earth Object Confirmation Page so that other astronomers could make additional observations. Scout, which was developed and is operated by the Center for Near Earth Object Studies (CNEOS) at NASA’s Jet Propulsion Laboratory in Southern California, automatically fetched the new data from that page, deducing the object’s possible trajectory and chances of impacting Earth. CNEOS calculates the orbit of every known NEO to provide assessments of potential impact hazards for the Planetary Defense Coordination Office (PDCO) at NASA Headquarters in Washington. With three observations posted to the confirmation page over 27 minutes, Scout initially identified that an impact was possible and that additional observations were urgently needed. As astronomers across Europe reported new data to the Minor Planet Center, the asteroid’s trajectory became better known and the probability of its impacting Earth significantly increased. Seventy minutes after 2024 BX1 was first spotted, Scout reported a 100% probability of Earth impact and began to narrow down the location and time. As tracking continued and more data became available over the next hour, Scout improved estimates of the time and location. Since the asteroid disintegrated over a relatively populated part of the world, many photos and videos of the fireball were posted online minutes after the event. Tracking NEOs The first asteroid to be discovered and tracked well before impacting our planet was 2008 TC3, which entered our atmosphere and broke up over Sudan in October 2008. That 13-foot-wide (4-meter-wide) asteroid scattered hundreds of small meteorites over the Nubian Desert. In early 2023, another tiny asteroid, designated 2023 CX1, was detected seven hours before it entered Earth’s atmosphere over northwestern France. As with 2024 BX1, Scout accurately predicted the location and time of impact. With NEO surveys becoming more sophisticated and sensitive, more of these harmless objects are being detected before entering our atmosphere, providing real exercises for NASA’s planetary defense program. The detals gathered from such events are helping to inform the agency’s mitigation strategies should a large and hazardous object on a collision course with our planet be detected in the future.
