A compilation video offers a look at 2024 highlights in such areas of work as propulsion testing, autonomous systems, range operations, community outreach, and STEM engagement. NASA’s Stennis Space Center near Bay St. Louis, Mississippi, celebrated propulsion testing and site operations milestones in 2024, all while inspiring the Artemis Generation and welcoming new leadership that will help NASA Stennis innovate and grow into the future. Featured highlights show a year of progress and vision, as NASA Stennis accelerates the exploration and commercialization of space, innovates to benefit NASA and industry, and leverages assets to grow as an impactful aerospace and technology hub. “These highlights are just a small snapshot of 2024 at NASA Stennis that show the future is bright,” Bailey said. “We have an incredibly talented and committed team of employees – and all of Mississippi can be proud of the work they do here at NASA Stennis. Together, with the Artemis Generation leading the way, we are returning to the Moon. Together, we are a part of something great.” New Center Leadership NASA Stennis Director John Bailey, right, and NASA Stennis Deputy Director Christine Powell stand near the United States Capitol during a visit to Washington, D.C. on Sept. 18. It marked the first visit to Capitol Hill for the center leaders since being named to their current roles. NASA/Stennis NASA Administrator Bill Nelson named John Bailey as director of NASA Stennis in April. Bailey had been serving as acting director since January 2024. “So much of NASA runs through Stennis,” said Nelson. “It is where we hone new and exciting capabilities in aerospace, technology, and deep space exploration. I am confident that John will lead the nation’s largest and premier propulsion test site to even greater success.” Four months later in August, Bailey announced that longtime propulsion engineer/manager Christine Powell had been selected as deputy director of NASA Stennis. Powell, the first woman selected as NASA Stennis deputy director, began her 33-year agency career as an intern at the center in 1991. She previously worked in multiple Engineering and Test Directorate roles, and most recently served as manager of the NASA Rocket Propulsion Test Program Office. Propulsion Activity NASA achieves a major milestone for future Artemis missions with successful completion of the second – and final – RS-25 engine certification test series April 3 on the Fred Haise Test Stand at NASA’s Stennis Space Center. NASA/Danny Nowlin NASA achieved major milestones for future Artemis missions at NASA Stennis in 2024. The NASA Stennis test team successfully completed a second – and final – RS-25 engine certification test series in April. The mission-critical series verified engine upgrades designed to enhance efficiency and reliability for future SLS (Space Launch System) missions. NASA Stennis crews also completed a safe lift and installation of the interstage simulator component in October needed for future testing of NASA’s exploration upper stage in the B-2 position of the Thad Cochran Test Stand. The component will function during Green Run testing like the SLS interstage section that helps protect the upper stage during Artemis launches. The test complex milestones support NASA’s goal of returning humans to the Moon and paving the way for future Mars exploration through Artemis missions. Commercial Testing NASA Stennis commercial tenant Rocket Lab completes a successful hot fire test of its Archimedes engine in its onsite test complex in the second half of 2024. Rocket Lab is one of numerous customers conducting test campaigns at NASA Stennis during the most recent year. Rocket Lab Already the nation’s largest multiuser propulsion test site, NASA Stennis aims to continue fueling growth of the commercial space market even further by working with aerospace companies to support a range of testing needs. In 2024, NASA Stennis supported work conducted by commercial companies such as Boeing, Blue Origin, Evolution Space, Launcher (a Vast company), Relativity Space, Rocket Lab, and Rolls-Royce. Officials from NASA Stennis and Roll-Royce also broke ground in June for a test pad located in the NASA Stennis E Test Complex. Rolls-Royce will conduct hydrogen testing for the Pearl 15 engine, which helps power the Bombardier Global 5500 & 6500 aircraft. ASTRA Mission Success Members of the NASA Stennis Autonomous Systems Laboratory team monitor the center’s in-space satellite payload from the onsite ASTRA (Autonomous Satellite Technology for Resilient Applications) Payload Operation Command Center. The ASTRA payload launched aboard the Sidus Space LizzieSat-1 small satellite in March 2024, with the NASA Stennis team announcing in July that it had achieved primary mission objectives. In September, the team announced the ASTRA mission would continue during the satellite’s planned four-year mission.NASA/Danny Nowlin In July, NASA Stennis and commercial partner Sidus Space Inc. announced primary mission success for the center’s historic in-space mission – an autonomous systems payload aboard an orbiting satellite. ASTRA (Autonomous Satellite Technology for Resilient Applications) is the on-orbit payload mission developed by NASA Stennis. The NASA Stennis ASTRA technology demonstrator is a payload rider aboard the Sidus Space premier satellite, LizzieSat-1 (LS-1) small satellite. Partner Sidus Space is responsible for all LS-1 mission operations, including launch and satellite activation, which allowed the NASA Stennis ASTRA team to complete its primary mission objectives. NASA Stennis announced in September it will continue the center’s in-space autonomous systems payload mission through a follow-on agreement with Sidus Space Inc. Range Operations The Skydweller Aero solar-powered, autonomous aircraft flies above the Thad Cochran Test Stand (B-1/B-2) at NASA’s Stennis Space Center during a September 2024 test operation. Skydweller Aero has an ongoing airspace agreement with NASA Stennis to conduct test flights of its aircraft in the area. Skydweller Aero During 2024, NASA Stennis entered into an agreement with Skydweller Aero Inc. for the company to operate its solar-powered autonomous aircraft in the site’s restricted airspace, a step towards achieving a strategic center goal. The agreement marked the first Reimbursable Space Act agreement between NASA Stennis and a commercial company to utilize the south Mississippi center’s unique capabilities to support testing and operation of uncrewed systems. The company announced in October it had completed an initial test flight campaign of the aircraft, including two test excursions totaling 16 and 22.5 hours. NASA Engagement NASA Stennis representatives inspire the Artemis Generation at the NAS Pensacola Blue Angels Homecoming Air Show on Nov. 1-2. NASA’s exhibits at the air show honored 55th anniversary of the Apollo 11 lunar landing and showcased the agency’s mission to inspire the world through discovery. NASA/Stennis NASA representatives participated in a variety of outreach activities during the past year to create meaningful connections with the Artemis Generation. The NASA ASTRO CAMP® Community Partners program, which originated at the south Mississippi NASA center, surpassed previous milestone marks in fiscal year 2024 by partnering with 373 community sites, including 50 outside the United States, to inspire youth, families, and educators. NASA Stennis also supported STEM (science, technology, engineering, and mathematics) engagement during the year. It once again joined with NASA’s Robotics Alliance Project and co-sponsor Mississippi Power to support the second annual For the Inspiration and Recognition of Science and Technology (FIRST) Robotics Magnolia Regional Competition in Laurel, Mississippi. The event attracted 37 high school teams from eight states and one from Mexico. The center also supported NASA activities during the 2024 total solar eclipse.

5 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) The Orion Environmental Test Article photographed inside the Thermal Vacuum Chamber on April 11, 2024, in the Space Environments Complex at NASA’s Neil Armstrong Test Facility in Sandusky, Ohio. Credit: NASA/Quentin Schwinn Making the voyage 1.4 million miles around the Moon and back — the farthest a spacecraft built for humans has ever gone — the Orion spacecraft has faced a battery of tests over the years. Though Orion successfully proved its capabilities in the harsh environment of space during the Artemis I mission, Orion’s evaluation did not end at splashdown. The crew module, now known as the Orion Environmental Test Article (ETA), returned to NASA’s Neil Armstrong Test Facility in Sandusky, Ohio, in January 2024 and completed an 11-month test campaign necessary for the safety and success of Artemis II, the first crewed mission under NASA’s Artemis campaign. Engineers and technicians from NASA and Lockheed Martin subjected the test article to the extreme conditions Orion may experience in a launch abort scenario. In the event of an emergency, Orion — and astronauts inside — will jettison away from the SLS (Space Launch System) rocket for a safe landing in the ocean. Experts at NASA’s Neil Armstrong Test Facility in Sandusky, Ohio, conducted a lightning test, which simulates the electromagnetic effects of a lightning strike to the vehicle on the launch pad awaiting liftoff. The Feb. 20, 2024 test proved the grounding path of the vehicle is operating as designed and protecting the vehicle from damage to any of its equipment or systems. Credit: NASA/Quentin Schwinn Experts installed NASA’s Launch Abort System, designed to carry the crew to safety in the event of an emergency during launch or ascent. The Orion test article was subjected to acoustic levels simulating both a nominal ascent and a launch abort scenario. The acoustic test chamber at NASA’s Neil Armstrong Test Facility in Sandusky, Ohio, blasted the test article at a volume of almost 164 decibels on Sept. 9, 2024. Credit: NASA/Jordan Salkin On Nov. 11, 2024, experts successfully at NASA’s Neil Armstrong Test Facility completed the docking mechanism jettison test, designed to connect and disconnect the Orion spacecraft to Gateway, a small space station that will orbit the Moon. They also completed the forward bay cover jettison test on Nov. 23, 2024, which is the last piece that must eject right before parachutes deploy, and successfully tested Orion’s uprighting system. Credit: NASA/Jordan Salkin “This event would be the maximum stress and highest load that any of the systems would see,” said Robert Overy, Orion ETA project manager, NASA’s Glenn Research Center in Cleveland. “We’re taking a proven vehicle from a successful flight and pushing it to its limits. The safety of the astronaut crew depends on this test campaign.” Experts conducted tests that simulated the noise levels of an abort during launch in addition to the electromagnetic effects of lightning strikes. The test campaign also jettisoned the test article’s docking module and parachute covers, as well as the crew module uprighting system, which consists of five airbags on top of the spacecraft that inflate upon splashdown. “It’s been a successful test campaign,” Overy said. “The data has matched the prediction models, and everything operated as expected after being subjected to nominal and launch abort acoustic levels. We are still analyzing data, but the preliminary results show the vehicle and facility operated as desired.” On. Nov. 23, 2024, after subjecting the Orion test article to launch abort-level acoustics, experts tested the functionality of the forward bay cover, which is the last piece that must eject before parachutes deploy. Credit: NASA/Jordan Salkin and Quentin Schwinn Testing Orion at such high acoustic levels was a major milestone for Artemis. The Reverberant Acoustic Test Facility, the world’s most powerful spacecraft acoustic test chamber, was built in 2011 in anticipation of this specific test campaign. “These tests are absolutely critical because we have to complete all of these tests to say the spacecraft design is safe and we’re ready to fly a crew for the first time on Artemis II,” said Michael See, ETA vehicle manager, Orion Program. “This is the first time we’ve been able to test a spacecraft on the ground in such an extreme abort-level acoustic environment.” The Orion Environmental Test Article with Launch Abort System installed moves to the Reverberant Acoustic Test Facility, the most powerful spacecraft acoustic test chamber in the world, on Sept. 9, 2024, at NASA’s Neil Armstrong Test Facility in Sandusky, Ohio. Credit: NASA/Jordan Salkin and Quentin Schwinn Part of NASA Glenn, Armstrong Test Facility is home to the world’s largest and most powerful space environment simulation chambers capable of testing full-sized spacecraft for all the extreme conditions of launch and spaceflight. The facility not only houses an acoustic test chamber, but also a thermal-vacuum chamber and spacecraft vibration system. “The facility is unique because there’s no other place in the world capable of testing spacecraft like this,” Overy said. “Armstrong Test Facility is a one-stop-shop for all your testing needs to prepare your spacecraft for the severe and challenging journey to and from space.” Orion’s Round-Trip Journey to Ohio This is not the first time Orion has been inside the walls of the Space Environments Complex at Armstrong Test Facility. The spacecraft underwent mission-critical testing in 2019, where it was subjected to extreme temperatures and an electromagnetic environment before it launched on Artemis I in 2022. “I remember when it first arrived, the gravity of its importance really hit home,” said Joshua Pawlak, test manager, NASA Glenn. “I thought to myself, on future Artemis missions, astronauts will be inside Orion heading to the Moon, and they’ll be depending on it for survival.” Pawlak was a mechanical test engineer when Orion made its first trip to the Sandusky facility. He participated in planning and coordinating testing of the vehicle and trained personnel. He managed the vehicle from the moment it arrived, through testing, and up until it departed for NASA’s Kennedy Space Center in Florida. Joshua Pawlak poses in front of the Artemis I Space Launch System rocket on Nov. 16, 2022, in Cape Canaveral, Florida. Credit: Joshua Pawlak “When it returned, I felt like I had a small part in this really big and exciting thing,” Pawlak said. “Seeing it come back blackened and scarred from the harsh environment of space was incredible. Space is not a friendly space, and I felt proud knowing that if there were astronauts on that vehicle, they would have survived. After the Orion test article departs from Glenn, it will head to Kennedy for additional testing. “When Artemis II launches and those astronauts are sitting on board, I’ll know that I did everything I could to ensure the vehicle is ready for them and going to perform as expected,” Pawlak said. “That’s why I do what I do.” Explore More 2 min read Station Science Top News: Dec. 13, 2024 Article 17 hours ago 3 min read NASA Sees Progress on Starlab Commercial Space Station Development Article 17 hours ago 7 min read NASA Kennedy Top 24 Stories of 2024 Article 5 days ago View the full article

X-rays are radiated by matter hotter than one million Kelvin, and high-resolution X-ray spectroscopy can tell us about the composition of the matter and how fast and in what direction it is moving. Quantum calorimeters are opening this new window on the Universe. First promised four decades ago, the quantum-calorimeter era of X-ray astronomy has finally dawned. Photo of the XRISM/Resolve quantum-calorimeter array in its storage container prior to integration into the instrument. The 6×6 array, 5 mm on a side, consists of independent detectors – each one a thermally isolated silicon thermistor with a HgTe absorber. The spectrometer consisting of this detector and other essential technologies separates astrophysical X-ray spectra into about 2400 resolution elements, which can be thought of as X-ray colors.NASA GSFC A quantum calorimeter is a device that makes precise measurements of energy quanta by measuring the temperature change that occurs when a quantum of energy is deposited in an absorber with low heat capacity. The absorber is attached to a thermometer that is somewhat decoupled from a heat sink so that the sensor can heat up and then cool back down again. To reduce thermodynamic noise and the heat capacity of the sensor, operation at temperatures less than 0.1 K is required. The idea for thermal measurement of small amounts of energy occurred in several places in the world independently when scientists observed pulses in the readout of low-temperature thermometers and infrared detectors. They attributed these spurious signals to passing cosmic-ray particles, and considered optimizing detectors for sensitive measurement of the energy of particles and photons. The idea to develop such sensors for X-ray astronomy was conceived at Goddard Space Flight Center in 1982 when X-ray astronomers were considering instruments to propose for NASA’s planned Advanced X-ray Astrophysics Facility (AXAF). In a fateful conversation, infrared astronomer Harvey Moseley suggested thermal detection could offer substantial improvement over existing solid-state detectors. Using Goddard internal research and development funding, development advanced sufficiently to justify, just two years later, proposing a quantum-calorimeter X-ray Spectrometer (XRS) for inclusion on AXAF. Despite its technical immaturity at the time, the revolutionary potential of the XRS was acknowledged, and the proposal was accepted. The AXAF design evolved over the subsequent years, however, and the XRS was eliminated from its complement of instruments. After discussions between NASA and the Japanese Institute of Space and Astronautical Science (ISAS), a new XRS was included in the instrument suite of the Japanese Astro-E X-ray observatory. Astro-E launched in 2000 but did not reach orbit due to an anomaly in the first stage of the rocket. Astro-E2, a rebuild of Astro-E, was successfully placed in orbit in 2005 and renamed Suzaku, but the XRS instrument ceased operation before observations started due to loss of the liquid helium, an essential part of the detector cooling system, caused by a faulty storage system. A redesigned mission, Astro-H, that included a quantum-calorimeter instrument with a redundant cooling system was successfully launched in 2016 and renamed Hitomi. Hitomi’s Soft X-ray Spectrometer (SXS) obtained high resolution spectra of the Perseus cluster of galaxies and a few other sources before a problem with the attitude control system caused the mission to be lost roughly one month after launch. Even so, Hitomi was the first orbiting observatory to obtain a scientific result using X-ray quantum calorimeters. The spectacular Perseus spectrum generated by the SXS motivated yet another attempt to implement a spaceborne quantum-calorimeter spectrometer. The X-ray Imaging and Spectroscopy Mission (XRISM) was launched in September 2023, with the spectrometer aboard renamed Resolve to represent not only its function but also the resolve of the U.S./Japan collaboration to study the Universe through the window of this new capability. XRISM has been operating well in orbit for over a year. Development of the Sensor Technology Development of the sensor technology employed in Resolve began four decades ago. Note that an X-ray quantum-calorimeter spectrometer requires more than the sensor technology. Other technologies, such as the coolers that provide a The sensors used from XRS through Resolve were all based on silicon-thermistor thermometers and mercury telluride (HgTe) X-ray absorbers. They used arrays consisting of 32 to 36 pixels, each of which was an independent quantum calorimeter. Between Astro-E and Astro-E2, a new method of making the thermistor was developed that significantly reduced its low-frequency noise. Other fabrication advances made it possible to make reproducible connections between absorbers and thermistors and to fit each thermistor and its thermal isolation under its X-ray absorber, making square arrays feasible. Through a Small Business Innovation Research (SBIR) contract executed after the Astro-E2 mission, EPIR Technologies Inc. reduced the specific heat of the HgTe absorbers. Additional improvements made to the cooler of the detector heat sink allowed operation at a lower temperature, which further reduced the specific heat. Together, these changes enabled the pixel width to be increased from 0.64 mm to 0.83 mm while still achieving a lower heat capacity, and thus improving the energy resolution. From Astro-E through Astro-H, the energy resolution for X-rays of energy around 6000 eV improved from 11 eV, to 5.5 eV, to 4 eV. No changes to the array design were made between Astro-H and XRISM. Resolve detector scientist Caroline Kilbourne installing the flight Resolve quantum-calorimeter array into the assembly that provides its electrical, thermal, and mechanical interfaces.NASA GSFC Over the same period, other approaches to quantum-calorimeter arrays optimized for the needs of future missions were developed. The use of superconducting transition-edge sensors (TES) instead of silicon (Si) thermistors led to improved energy resolution, more pixels per array, and multiplexing (a technique that allows multiple signals to be carried on a single wire). Quantum-calorimeter arrays with thousands of pixels are now standard, such as in the NASA contribution to the future European New Advanced Telescope for High-ENergy Astrophysics (newAthena) mission. And quantum calorimeters using paramagnetic thermometers — which unlike TES and Si thermistors require no dissipation of heat in the thermometer for it to be read out — combined with high-density wiring are a promising route for realizing even larger arrays. (See Astrophysics Technology Highlight on these latest developments.) The Resolve instrument aboard XRISM (X-ray Imaging and Spectroscopy Mission) captured data from the center of galaxy NGC 4151, where a supermassive black hole is slowly consuming material from the surrounding accretion disk. The resulting spectrum reveals the presence of iron in the peak around 6.5 keV and the dips around 7 keV, light thousands of times more energetic that what our eyes can see. Background: An image of NGC 4151 constructed from a combination of X-ray, optical, and radio light.Spectrum: JAXA/NASA/XRISM Resolve. Background: X-rays, NASA/CXC/CfA/J.Wang et al.; optical, Isaac Newton Group of Telescopes, La Palma/Jacobus Kapteyn Telescope; radio, NSF/NRAO/VLA Results from Resolve So, what is Resolve revealing about the Universe? Through spectroscopy alone, Resolve allows us to construct images of complex environments where collections of gas and dust with various attributes exist, emitting and absorbing X-rays at energies characteristic of their various compositions, velocities, and temperatures. For example, in the middle of the galaxy known as NCG 4151 (see figure above), matter spiraling into the central massive black hole forms a circular structure that is flat near the black hole, more donut-shaped further out, and, according to the Resolve data, a bit lumpy. Matter near the black hole is heated up to X-ray-emitting temperatures and irradiates the matter in the circular structure. The Resolve spectrum has a bright narrow emission line (peak) from neutral iron atoms that must be coming from colder matter in the circular structure, because hotter material would be ionized, and would have a different emission signature. Nonetheless, the shape of the iron line needs three components to describe it, each coming from a different lump in the circular structure. The presence of absorption lines (dips) in the spectrum provides further detail about the structure of the infalling matter. A second example is the detection of X-ray emission by Resolve from the debris of stars that have exploded, such as N132D (see figure below), that will improve our understanding of the explosion mechanism and how the elements produced in stars get distributed, and allow us to infer the type of star each was before ending in a supernova. Elements are identified by their characteristic emission lines, and shifts of those lines via the Doppler effect tell us how fast the material is moving. XRISM’s Resolve instrument captured data from supernova remnant N132D in the Large Magellanic Cloud to create the most detailed X-ray spectrum of the object ever made. The spectrum reveals peaks associated with silicon, sulfur, argon, calcium, and iron. Inset at right is an image of N132D captured by XRISM’s Xtend instrument.JAXA/NASA/XRISM Resolve and Xtend These results are just the beginning. The rich Resolve data sets are identifying complex velocity structures, rare elements, and multiple temperature components in a diverse ensemble of cosmic objects.

Benchmarks for solidifying metal alloys Researchers report benchmark data for modeling the growth of specific types of microstructures that form during solidification of metal alloys under different conditions. These microstructures affect the properties of materials and products such as refrigeration devices and solar cells. The ESA (European Space Agency) Columnar-to-Equiaxed Transition in Solidification Processing (CETSOL) investigation studied the processes of metal alloy solidification and the crystal patterns that form as liquids transition to solids. Results could improve ground-based development of lightweight, high-performance structural materials for space and ground applications. Microgravity is key to this research because it eliminates influences of gravity during solidification and allows researchers to control turbulence and convection. European Space Agency (ESA) astronaut Frank De Winne works on the Columnar-to-Equiaxed Transition in Solidification Processing (CETSOL) investigation in the U.S. Destiny Laboratory.NASA Composite materials shield against radiation, other hazards Researchers found no degradation in two multifunctional radiation shielding composite materials after exposure to space. This finding suggests that composite materials with a surface layer and a coating could protect crews on future missions from radiation and other hazards of space. Materials ISS Experiment Flight Facility (MISSE-FF) continued a series of investigations examining how exposure to space affects materials and material configurations used for space missions. The MISSE-13 suite of materials included a multifunctional composite material for shielding crew members in habitats and spacecraft beyond low Earth orbit against radiation, atomic oxygen, and temperature extremes. An image of the Materials ISS Experiment Flight Facility (MISSE-FF) platform used for MISSE experiments.NASA Modeling the use of boiling to transfer heat Researchers developed an algorithm to determine the amount of heat transferred via boiling of a liquid and showed that maximum heat flow occurs where the bubble contacts the surface and the liquid. This finding could inform design of thermal control systems for spacecraft and for cooling electronics and other applications on Earth. ESA’s Multiscale Boiling examined the dynamics of heat transfer via boiling, which generates vapor bubbles that lift heat from a surface. This technique is less efficient in microgravity because boiling happens more slowly, and bubbles remain near the surface in the absence of buoyancy. But microgravity also makes it possible to observe effects that are too fast and too small to be measured under normal gravity conditions, helping scientists understand the dynamics of boiling heat transfer.

The four milestones are part of a NASA Space Act Agreement awarded in 2021 and focused on reviews of the habitat structural test article preliminary design, systems integration, integrated operations, and a habitat structural test plan. “These milestone achievements are great indicators to reflect Starlab’s commitment to the continued efforts and advancements of their commercial destination,” said Angela Hart, program manager for NASA’s Commercial Low Earth Orbit Development Program. “As we look forward to the future of low Earth orbit, every successful milestone is one step closer to creating a dynamic and robust commercialized low Earth orbit.” The commercial space station is designed to launch on a single flight and includes a large habitation and laboratory module with a smaller service module for power and propulsion. Earlier this year, Starlab Space completed a structural test article preliminary design review, supported by NASA. The structural test article is an engineering development unit of the station’s habitation module, which is where astronauts will spend most of their time living and working aboard the future commercial destination. An engineering development unit is a physical model that is used to test and verify the design of a project, such as a space station. A digital rendering of the Starlab free-flying commercial destination, which continues to be developed as part of a Space Act Agreement with NASACredits: Starlab Starlab also recently shared a test plan for the structural test article, which included defining qualification tests of the development unit from welding verifications to proof pressure and static load testing, among others. During proof pressure tests, a spacecraft component or system is pressurized to a significantly higher than normal operating pressure to verify its structural integrity, and a static load test measures the response of a component or system under an applied load. In addition, Starlab completed integration operations and systems integration reviews. These reviews included updates on system and station architecture, segment interfaces, and program goals, as well as a comprehensive look into the program’s requirements. Starlab also is set to complete a preliminary design review and phase 1 safety review by the end of the year. This review is meant to demonstrate that the station’s design meets system requirements, including human spaceflight verification, with acceptable risk. The safety review will summarize the current design and general safety approach for the destination. NASA is supporting the design and development of multiple commercial space stations, including Starlab, through funded and unfunded agreements. The current design and development phase will be followed by the procurement of services from one or more companies, where NASA aims to be one of many customers for low Earth orbit destinations. NASA’s low Earth orbit microgravity strategy builds on the agency’s extensive human spaceflight experience to advance future scientific and exploration goals. As the International Space Station nears the end of operations, NASA plans to transition to a new low Earth orbit model to continue leveraging microgravity benefits.

In the distance is the Moon, and a red star representing Mars.Credit: NASA As part of the agency’s efforts to enable broader use of space, NASA has released its final goals and objectives for low Earth orbit, defining the long-term approach toward advancing microgravity science, technology, and exploration for the benefit of all. Developed with input from a wide range of stakeholders, NASA’s Low Earth Orbit Microgravity Strategy will guide the agency toward the next generation of continuous human presence in orbit, enable greater economic growth, and maintain international partnerships. “As we near the retirement of the International Space Station in 2030, these objectives are a pivotal next step in solidifying U.S. leadership in space,” said NASA Deputy Administrator Pam Melroy. “Our consultation with industry, academia, and international partners has helped refine a visionary roadmap for our future in low Earth orbit, which will be enabled by a continuous human presence. Together, we are ensuring that the benefits of exploring space continue to grow – advancing science, innovation, and opportunities for all, while preparing for humanity’s next giant leap of exploring the Moon, Mars and beyond.” In early 2024, NASA initiated a planning process that included drafting an initial set of goals and objectives for the low Earth orbit microgravity environment and seeking feedback from its workforce, government partners, industry, academia, international space agencies, and the public. The agency reviewed more than 1,800 comments and hosted two workshops, resulting in essential adjustments to the goals and objectives to better align with its partners. The final framework includes 13 goals and 44 objectives across seven key areas: commercial low Earth orbit infrastructure, operations, science, research and technology development for exploration, international cooperation, workforce development and science, technology, engineering, and mathematics (STEM) engagement, and public engagement. The agency’s efforts in low Earth orbit are integral to its broader ambitions for deep space exploration. The microgravity environment in low Earth orbit provides a cost-effective, easily accessible proving ground for technologies and research necessary for human missions to explore the solar system. With most of the journey to Moon and Mars occurring in microgravity, the objectives give the opportunity to continue vital human research, test future exploration systems, and retain the critical skills needed to operate in the microgravity environment. “These finalized objectives represent a clear path forward as NASA transitions from the International Space Station to a new era of commercial space stations,” said Robyn Gatens, director of the International Space Station and acting director of commercial spaceflight. “Low Earth orbit will remain a hub for scientific discovery, technological advancement, and international cooperation, while making strategic investments in a commercial space ecosystem that benefits not just NASA, but the entire space community.” The low Earth orbit microgravity goals and objectives, combined with significant stakeholder engagement, drive NASA’s need to maintain an unbroken, continuous heartbeat of humans in the commercial low Earth orbit destinations era. NASA requires long-duration flights to mitigate risk for future trips to the Red Planet. To ensure reliable access to and use of low Earth orbit, a diversity of providers operating on a regular cadence is essential. The objectives will also guide the development of requirements for future commercial space stations that will support NASA’s missions, while reducing risk for human missions to Mars, preserving operational skills, advancing critical scientific research, and sustaining engagement with international and commercial partners. “Collaboration and consultation remain a cornerstone of our low Earth orbit strategy,” said John Keefe, director of cross-agency strategy integration at NASA. “The objectives we’ve established will help NASA craft a work plan that ensures NASA is positioned to meet current and future needs and prioritizes the development of critical capabilities for low Earth orbit.” The low Earth orbit microgravity goals and objectives are available online at: https://go.nasa.gov/3DsMtNI -end- Amber Jacobson Headquarters, Washington 202-358-1600 amber.c.jacobson@nasa.gov Share Details Last Updated Dec 16, 2024 LocationNASA Headquarters Related TermsPamela A.

4 Min Read Celebrating 20 Years: Night Sky Network 2023 Partial Solar Eclipse Viewing at Camino Real Marketplace with the View the Santa Barbara Astronomical Unit. Credits: Photo by Chuck McPartlin by Vivan White & Kat Troche of the Astronomical Society of the Pacific NASA’s Night Sky Network is one of the most successful and longstanding grassroots initiatives for public engagement in astronomy education. Started in 2004 with the PlanetQuest program out of the Jet Propulsion Laboratory and currently supported by NASA’s Science Activation, the Night Sky Network (NSN) plays a critical role in fostering science literacy through astronomy. By connecting NASA science and missions to support amateur astronomy clubs, NSN leverages the expertise and enthusiasm of club members, who bring this knowledge to schools, museums, observatories, and other organizations, bridging the gap between NASA science and the public. Now in its 20th year, NSN supports over 400 astronomy clubs dedicated to bringing the wonder of the night sky to their communities across the US, connecting with 7.4 million people across the United States and its territories since its inception. International Observe the Moon Night, September 2024 Credit: Oklahoma City Astronomy Club Humble Beginnings It all started with an idea – astronomy clubs already do great outreach, and club members know a lot of astronomy (shown definitively by founder Marni Berendsen’s research), and they love to talk with the public – how could NASA support these astronomy clubs in sharing current research and ideas using informal activities designed for use in the places that amateur astronomers do outreach. Thanks to funding through NASA JPL’s PlanetQuest public engagement program, the Night Sky Network was born in 2004, with more than 100 clubs joining the first year. Raynham Public Observing Night, February 2004 Credit: Astronomical Society of Southern New England/Mark Gibson As quoted from the first NSN news article, “NASA is very excited to be working closely with the amateur astronomy community,” said Michael Greene, current Director for Communications and Education and former head of public engagement for JPL’s Navigator Program and PlanetQuest initiatives, “Amateurs want more people to look at the sky and understand astronomy, and so do we. Connecting what we do with our missions to the sense of wonder that comes when you look up at the stars and the planets is one of our long-term objectives. We have a strong commitment to inspiring the next generation of explorers. Lending support to the energy that the amateur astronomy community brings to students and the public will allow NASA to reach many more people.” Taking off like a rocket, Night Sky Network had over 100 clubs registered on their website within the first year. The Toolkits Outreach Toolkits were developed to assist clubs with their endeavors. These kits included educational materials, hands-on activities, and guides to explaining topics in an accessible way. So far, 13 toolkits have been created with topics ranging from the scale of the universe to how telescopes work. To qualify for these free Toolkits, clubs must be active in their communities, hosting two outreach events every three months or five outreach events within a calendar year. Supplemental toolkits were also created based on special events, such as the solar eclipses and the 50th anniversary of Apollo’s Moon landing. A new toolkit is in development to teach audiences about solar science, and NSN is on track to support clubs well into the future. Rye Science Day, October 2014 Credit: Southern Colorado Astronomical Society/Malissa Pacheco NSN also hosts archived video trainings on these toolkits and other topics via its YouTube channel and a monthly webinar series with scientists from various institutions worldwide. Lastly, a monthly segment called Night Sky Notes is produced for clubs to share with their audiences via newsletters and mailing lists. Sharing the Universe In 2007, a National Science Foundation grant provided funding for further research into astronomy club needs. From that came three resources for clubs – the Growing Your Astronomy Club and Getting Started with Outreach video series, as well as an updated website with a national calendar and club and event coordination. Now you can find hundreds of events each month across the country, including virtual events that you can join from anywhere.

NASA/JPL-Caltech Earth planning date: Friday, Dec. 13, 2024 Curiosity continues to make great progress over the Mount Sharp bedrock and will spend the weekend investigating the northern base of the “Texoli” butte. The science team back on Earth enjoyed taking in the beautiful views of nearby “Wilkerson” butte and “Gould Mesa” while digging into the workspace in front of us to create a hefty to-do list for our roving geologist on Mars. The rocks at the rover’s wheels today consisted of dusty, pale-colored bedrock that had a range of textures. We used the dust removal tool (DRT), MAHLI, and APXS instruments to characterize lighter, smooth bedrock at “Calabasas Peak,” and slightly darker, rougher bedrock at “Triunfo Canyon.” The ChemCam team used the Laser-Induced Breakdown Spectroscopy (LIBS) to analyze the composition of the rougher bedrock at “Chilao” and a vein that cuts through the bedrock at “Ojai,” and Mastcam provided the supporting documentation images of each target. The Mastcam team assembled a variety of images and mosaics in the workspace and beyond. Two stereo mosaics documented the network of fractures in the bedrock at “Fern Dell” while a stereo mosaic of “Amir’s Garden” will be used to observe possible deformation in the rocks. A few single-frame images of troughs in the workspace will be used to investigate active surface processes. Further in the distance, Mastcam created a stereo mosaic of “Jawbone Canyon” to image potential aeolian ripples, and supported a ChemCam long-distance RMI image of a crater in the drive direction called “Grant Lake.” Lastly, ChemCam planned a long-distance RMI image to get a closer look at the structures within Gould Mesa. Curiosity will drive 44 meters (about 144 feet) to the west over the weekend as we continue to close in on the intriguing boxwork structures. Lastly, the environmental group rounded out the plan with activities including cloud observations, dust-devil monitoring, and surveys of the amount of dust in the atmosphere.

5 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) Seen at the center of this image, NASA’s retired InSight Mars lander was captured by the agency’s Mars Reconnaissance Orbiter using its High-Resolution Imagine Science Experiment (HiRISE) camera on Oct. 23, 2024.NASA/JPL-Caltech/University of Arizona New images taken from space show how dust on and around InSight is changing over time — information that can help scientists learn more about the Red Planet. NASA’s Mars Reconnaissance Orbiter (MRO) caught a glimpse of the agency’s retired InSight lander recently, documenting the accumulation of dust on the spacecraft’s solar panels. In the new image taken Oct. 23 by MRO’s High-Resolution Imaging Science Experiment (HiRISE) camera, InSight’s solar panels have acquired the same reddish-brown hue as the rest of the planet. After touching down in November 2018, the lander was the first to detect the Red Planet’s marsquakes, revealing details of the crust, mantle, and core in the process. Over the four years that the spacecraft collected science, engineers at NASA’s Jet Propulsion Laboratory in Southern California, which led the mission, used images from InSight’s cameras and MRO’s HiRISE to estimate how much dust was settling on the stationary lander’s solar panels, since dust affected its ability to generate power. NASA retired InSight in December 2022, after the lander ran out of power and stopped communicating with Earth during its extended mission. But engineers continued listening for radio signals from the lander in case wind cleared enough dust from the spacecraft’s solar panels for its batteries to recharge. Having detected no changes over the past two years, NASA will stop listening for InSight at the end of this year.

Studying it helps scientists understand the planet and engineers prepare for future missions (solar-powered and otherwise), since dust can get into sensitive mechanical parts. When InSight was still active, scientists matched MRO images of dust devil tracks winding across the landscape with data from the lander’s wind sensors, finding these whirling weather phenomena subside in the winter and pick up again in the summer. The imagery also helped with the study of meteoroid impacts on the Martian surface. The more craters a region has, the older the surface there is. (This isn’t the case with Earth’s surface, which is constantly recycled as tectonic plates slide over one another.) The marks around these craters fade with time. Understanding how fast dust covers them helps to ascertain a crater’s age. Another way to estimate how quickly craters fade has been studying the ring of blast marks left by InSight’s retrorocket thrusters during landing. Much more prominent in 2018, those dark marks are now returning to the red-brown color of the surrounding terrain. HiRISE has captured many other spacecraft images, including those of NASA’s Perseverance and Curiosity rovers, which are still exploring Mars, as well as inactive missions, like the Spirit and Opportunity rovers and the Phoenix lander. “It feels a little bittersweet to look at InSight now. It was a successful mission that produced lots of great science. Of course, it would have been nice if it kept going forever, but we knew that wouldn’t happen,” Daubar said. More About MRO and InSight The University of Arizona, in Tucson, operates HiRISE, which was built by Ball Aerospace & Technologies Corp., in Boulder, Colorado. A division of Caltech in Pasadena, California, JPL manages the MRO project and managed InSight for NASA’s Science Mission Directorate, Washington. The InSight mission was part of NASA’s Discovery Program, managed by the agency’s Marshall Space Flight Center in Huntsville, Alabama. Lockheed Martin Space in Denver built the InSight spacecraft, including its cruise stage and lander, and supported spacecraft operations for the mission. A number of European partners, including France’s Centre National d’Études Spatiales (CNES) and the German Aerospace Center (DLR), supported the InSight mission. CNES provided the Seismic Experiment for Interior Structure (SEIS) instrument to NASA, with the principal investigator at IPGP (Institut de Physique du Globe de Paris). Significant contributions for SEIS came from IPGP; the Max Planck Institute for Solar System Research (MPS) in Germany; the Swiss Federal Institute of Technology (ETH Zurich) in Switzerland; Imperial College London and Oxford University in the United Kingdom; and JPL. DLR provided the Heat Flow and Physical Properties Package (HP3) instrument, with significant contributions from the Space Research Center (CBK) of the Polish Academy of Sciences and Astronika in Poland. Spain’s Centro de Astrobiología (CAB) supplied the temperature and wind sensors.

Credits: NASA, ESA, CSA, STScI, Olivia C. Jones (UK ATC), Guido De Marchi (ESTEC), Margaret Meixner (USRA) NASA’s James Webb Space Telescope just solved a conundrum by proving a controversial finding made with the agency’s Hubble Space Telescope more than 20 years ago. In 2003, Hubble provided evidence of a massive planet around a very old star, almost as old as the universe. Such stars possess only small amounts of heavier elements that are the building blocks of planets. This implied that some planet formation happened when our universe was very young, and those planets had time to form and grow big inside their primordial disks, even bigger than Jupiter. But how? This was puzzling. To answer this question, researchers used Webb to study stars in a nearby galaxy that, much like the early universe, lacks large amounts of heavy elements. They found that not only do some stars there have planet-forming disks, but that those disks are longer-lived than those seen around young stars in our Milky Way galaxy. “With Webb, we have a really strong confirmation of what we saw with Hubble, and we must rethink how we model planet formation and early evolution in the young universe,” said study leader Guido De Marchi of the European Space Research and Technology Centre in Noordwijk, Netherlands. Image A: Protoplanetary Disks in NGC 346 (NIRCam Image) This is a James Webb Space Telescope image of NGC 346, a massive star cluster in the Small Magellanic Cloud, a dwarf galaxy that is one of the Milky Way’s nearest neighbors. With its relative lack of elements heavier than hydrogen and helium, the NGC 346 cluster serves as a nearby proxy for studying stellar environments with similar conditions in the early, distant universe. Ten, small, yellow circles overlaid on the image indicate the positions of the ten stars surveyed in this study. NASA, ESA, CSA, STScI, Olivia C. Jones (UK ATC), Guido De Marchi (ESTEC), Margaret Meixner (USRA) A Different Environment in Early Times In the early universe, stars formed from mostly hydrogen and helium, and very few heavier elements such as carbon and iron, which came later through supernova explosions. “Current models predict that with so few heavier elements, the disks around stars have a short lifetime, so short in fact that planets cannot grow big,” said the Webb study’s co-investigator Elena Sabbi, chief scientist for Gemini Observatory at the National Science Foundation’s NOIRLab in Tucson. “But Hubble did see those planets, so what if the models were not correct and disks could live longer?” To test this idea, scientists trained Webb on the Small Magellanic Cloud, a dwarf galaxy that is one of the Milky Way’s nearest neighbors. In particular, they examined the massive, star-forming cluster NGC 346, which also has a relative lack of heavier elements. The cluster served as a nearby proxy for studying stellar environments with similar conditions in the early, distant universe. Hubble observations of NGC 346 from the mid 2000s revealed many stars about 20 to 30 million years old that seemed to still have planet-forming disks around them. This went against the conventional belief that such disks would dissipate after 2 or 3 million years. “The Hubble findings were controversial, going against not only empirical evidence in our galaxy but also against the current models,” said De Marchi. “This was intriguing, but without a way to obtain spectra of those stars, we could not really establish whether we were witnessing genuine accretion and the presence of disks, or just some artificial effects.” Now, thanks to Webb’s sensitivity and resolution, scientists have the first-ever spectra of forming, Sun-like stars and their immediate environments in a nearby galaxy. “We see that these stars are indeed surrounded by disks and are still in the process of gobbling material, even at the relatively old age of 20 or 30 million years,” said De Marchi. “This also implies that planets have more time to form and grow around these stars than in nearby star-forming regions in our own galaxy.” Image B: Protoplanetary Disks in NGC 346 Spectra (NIRSpec) This graph shows, on the bottom left in yellow, a spectrum of one of the 10 target stars in this study (as well as accompanying light from the immediate background environment). Spectral fingerprints of hot atomic helium, cold molecular hydrogen, and hot atomic hydrogen are highlighted. On the top left in magenta is a spectrum slightly offset from the star that includes only light from the background environment. This second spectrum lacks a spectral line of cold molecular hydrogen. On the right is the comparison of the top and bottom lines. This comparison shows a large peak in the cold molecular hydrogen coming from the star but not its nebular environment. Also, atomic hydrogen shows a larger peak from the star. This indicates the presence of a protoplanetary disk immediately surrounding the star. The data was taken with the microshutter array on the James Webb Space Telescope’s NIRSpec (Near-Infrared Spectrometer) instrument. Illustration: NASA, ESA, CSA, Joseph Olmsted (STScI) A New Way of Thinking This finding refutes previous theoretical predictions that when there are very few heavier elements in the gas around the disk, the star would very quickly blow away the disk. So the disk’s life would be very short, even less than a million years. But if a disk doesn’t stay around the star long enough for the dust grains to stick together and pebbles to form and become the core of a planet, how can planets form? The researchers explained that there could be two distinct mechanisms, or even a combination, for planet-forming disks to persist in environments scarce in heavier elements. First, to be able to blow away the disk, the star applies radiation pressure. For this pressure to be effective, elements heavier than hydrogen and helium would have to reside in the gas. But the massive star cluster NGC 346 only has about ten percent of the heavier elements that are present in the chemical composition of our Sun. Perhaps it simply takes longer for a star in this cluster to disperse its disk. The second possibility is that, for a Sun-like star to form when there are few heavier elements, it would have to start from a larger cloud of gas. A bigger gas cloud will produce a bigger disk. So there is more mass in the disk and therefore it would take longer to blow the disk away, even if the radiation pressure were working in the same way. “With more matter around the stars, the accretion lasts for a longer time,” said Sabbi. “The disks take ten times longer to disappear. This has implications for how you form a planet, and the type of system architecture that you can have in these different environments. This is so exciting.” The science team’s paper appears in the Dec. 16 issue of The Astrophysical Journal.

5 Min Read NASA DAVINCI Mission’s Many ‘Firsts’ to Unlock Venus’ Hidden Secrets The surface of Venus is an inferno with temperatures hot enough to melt lead. This image is a composite of data from NASA’s Magellan spacecraft and Pioneer Venus Orbiter. Credits: NASA/JPL-Caltech NASA’s DAVINCI — Deep Atmosphere Venus Investigation of Noble gases, Chemistry, and Imaging — mission embodies the spirit of innovation and exploration that its namesake, Leonardo da Vinci, was famous for. Scheduled to launch in the early 2030s, DAVINCI will explore Venus with both a spacecraft and a descent probe. DAVINCI’s probe will be the first in the 21st century to brave Venus’ atmosphere as it descends from above the planet’s clouds down to its surface. Two other missions, NASA’s VERITAS and ESA’s (European Space Agency) Envision, will also explore Venus in the 2030s from the planet’s orbit. The DAVINCI spacecraft will study Venus’ clouds and highlands during two flybys. It also will release a spherical probe, about 3 feet wide, that will plunge through the planet’s thick atmosphere and corrosive clouds, taking measurements and capturing high-resolution images of the Venusian surface as it descends below the clouds. Here are some of DAVINCI’s coming “firsts” in Venus exploration: Exploring Solar System’s One-of-a-Kind Terrain The DAVINCI mission will be the first to closely explore Alpha Regio, a region known as a “tessera.” So far found only on Venus, where they make up about 8% of the surface, tesserae are highland regions similar in appearance to rugged mountains on Earth. Previous missions discovered these features using radar instruments, but of the many international spacecraft that dove through Venus’ atmosphere between 1966 and 1985, none studied or photographed tesserae. Thought to be ancient continents, tesserae like Alpha Regio may be among the oldest surfaces on the planet, offering scientists access to rocks that are billions of years old. By studying these rocks from above Alpha Regio, DAVINCI scientists may learn whether ancient Venus had continents and oceans, and how water may have influenced the surface. Photographing One of the Oldest Surfaces on Venus The DAVINCI probe will capture the first close-up views of Alpha Regio with its infrared and optical cameras; these will also be the first photos of the planet’s surface taken in more than 40 years. With surface temperatures reaching 900° F and air pressure 90 times that of Earth’s, Venus’ harsh environment makes exploration challenging, while its opaque atmosphere obscures direct views. Typically, scientists rely on radar instruments from Earth or Venus-orbiting spacecraft to study its terrain. But DAVINCI’s probe will descend through the atmosphere and below the clouds for a clear view of the mountains and plains. It will capture images comparable to an airplane’s landing view of Earth’s surface. Scientists will use the photos to compile 3D maps of Alpha Regio that will provide more detail than ever of Venus’ terrain, helping them look for rocks that are usually only made in association with water. Unveiling Secrets of Venus’ Mysterious Lower Atmosphere The DAVINCI mission will be the first to analyze the chemical composition of Venus’ lower atmosphere through measurements taken at regular intervals, starting from approximately 90,000 feet above the surface and continuing until just before impact. This region is critical because it contains gases and chemical compounds that may originate from Venus’ lower clouds, surface, or even subsurface. For example, sulfur compounds detected here could indicate whether Venusian volcanoes are currently active or were active in the recent past. Noble gases (like helium or xenon), on the other hand, remain chemically inert and maintain stable concentrations, offering invaluable clues about Venus’ ancient history, such as the planet’s past water inventory. By comparing Venus’ noble gas composition with that of Earth and Mars, scientists can better understand why these planets — despite forming from similar starting materials — evolved into dramatically different worlds. Moreover, DAVINCI’s measurements of isotopes and trace gases in the lower atmosphere will shed light on Venus’ water history, from ancient times to the present, and the processes that triggered the planet’s extreme greenhouse effect. State-of-the-Art Technology to Study Venus in Detail Thanks to modern technology, the DAVINCI probe will be able to do things 1980s-era spacecraft couldn’t. The descent probe will be better equipped than previous probes to protect the sensitive electronics inside of it, as it will be lined on the inside with high-temperature, multi-layer insulation — layers of advanced ceramic and silica fabrics separated by aluminum sheets. Venus’ super thick atmosphere will slow the probe’s descent, but a parachute will also be released to slow it down further. Most Earth-friendly parachute fabrics, like nylon, would dissolve in Venus’ sulfuric acid clouds, so DAVINCI will have to use a different type of material than previous Venus missions did: one that’s resistant to acids and five times stronger than steel.

NASA/Steve Freeman On Oct. 22, 2024, the latest iteration of an atmospheric probe developed by researchers at NASA’s Armstrong Flight Research Center in Edwards, California, successfully completed a test flight. Building on NASA 1960s research on lifting body aircraft, which use the aircraft’s shape for lift instead of wings, the concept could offer future scientists a potentially better and more economical way to collect data on other planets. Testing demonstrated the shape of the probe works. The atmospheric probe flew after release from a quad-rotor remotely piloted aircraft above Rogers Dry Lake, a flight area adjacent to NASA Armstrong. “I’m ecstatic,” said John Bodylski, atmospheric probe principal investigator at NASA Armstrong. “It was completely stable in flight. We will be looking at releasing it from a higher altitude to keep it flying longer and demonstrate more maneuvers.” See more photos from the test flight.

La sonda medirá las ondas de choque del X-59 de la NASA.NASA/Steve Freeman Read this story in English here. La NASA pronto pondrá a prueba los avances realizados en una herramienta clave para medir los singulares ‘golpes sónicos’ que su avión supersónico silencioso de investigación X-59 producirá durante el vuelo. Una sonda de detección de impactoses una sonda de datos de aire en forma cónica desarrollada con características específicas para capturar las singulares ondas de choque que producirá el X-59. Investigadores del Centro de Investigación de Vuelo Armstrong de la NASA en Edwards, California, desarrollaron dos versiones de la sonda para recopilar datos precisos de presión durante el vuelo supersónico. Una de las sondas está optimizada para mediciones de campo cercano, capturando las ondas de choque que se producen muy cerca de donde las generará el X-59. La segunda sonda de detección de impactos medirá el centro del campo y recopilará datos a altitudes de entre 5.000 y 20.000 pies por debajo del avión. Cuando un avión vuela a velocidades supersónicas, genera ondas de choque que viajan a través del aire circundante, produciendo fuertes estampidos sónicos. El X-59 está diseñado para desviar esas ondas de choque, reduciendo los fuertes estampidos sónicos a golpes sónicos más silenciosos. Durante los vuelos de prueba, un avión F-15B con una sonda de detección de impactos acoplada a su morro volará con el X-59. La sonda, de aproximadamente 1,80 metros (6 pies), recolectará continuamente miles de muestras de presión por segundo, captando los cambios de presión del aire mientras vuela a través de ondas de choque. Los datos de los sensores serán vitales para validar los modelos informáticos que predicen la fuerza de las ondas de choque producidas por el X-59, la pieza central de la misión Quesst de la NASA. “Una sonda de detección de impactos actúa como fuente de la verdad, comparando los datos previstos con las mediciones del mundo real”, dijo Mike Frederick, investigador principal de la NASA para la sonda. Para la sonda de campo cercano, el F-15B volará cerca del X-59 a su altitud de crucero de aproximadamente 18.000 metros (55.000 pies), utilizando una configuración de “seguir al líder” que permitirá a los investigadores analizar ondas de choque en tiempo real. La sonda de campo medio, destinada para misiones separadas, recopilará datos más útiles a medida que las ondas de choque viajen más cerca al suelo. La capacidad de las sondas para captar pequeños cambios de presión es especialmente importante para el X-59, ya que se espera que sus ondas de choque sean mucho más débiles que las de la mayoría de los aviones supersónicos. Al comparar los datos de las sondas con las predicciones de modelos de computadora avanzados, los investigadores pueden evaluar con mayor precisión. “Las sondas tienen cinco puertos de presión, uno en la punta y cuatro alrededor del cono”, explica Frederick. “Estos puertos miden los cambios de presión estática a medida que el avión vuela a través de las ondas de choque, lo que nos ayuda a comprender las características de choque de un avión en particular”. Estos puertos combinan sus mediciones para calcular la presión local, la velocidad y la dirección del flujo de aire. Los investigadores pronto evaluarán actualizaciones de la sonda de detección de impactos de campo cercano a través de vuelos de prueba, en los que la sonda, montada en un F-15B, recopilará datos persiguiendo a un segundo F-15 durante un vuelo supersónico. Las actualizaciones de la sonda incluyen la colocación de los transductores de presión – dispositivos que miden la presión del aire en el cono – a sólo 5 pulgadas de sus puertos. Los diseños anteriores colocaban esos transductores a casi 3 metros (12 pies) de distancia, lo que retrasaba el tiempo de grabación y distorsionaba las mediciones. La sensibilidad a la temperatura de los diseños anteriores también presentó un desafío, ya que provocó fluctuaciones en la precisión cuando cambiaban las condiciones. Para solucionar esto, el equipo diseñó un sistema de calefacción para mantener los transductores de presión a una temperatura constante durante el vuelo. “La sonda cumplirá los requisitos de resolución y precisión de la misión Quesst”, afirmó Frederick. “Este proyecto muestra cómo la NASA puede tomar tecnología existente y adaptarla para resolver nuevos desafíos”.

5 Min Read NASA Technologies Aim to Solve Housekeeping’s Biggest Issue – Dust This artist rendering of Electrostatic Dust Lofting (EDL) examines the lofting of lunar dust when electrostatic charging occurs after exposure to ultraviolet light. If you thought the dust bunnies under your sofa were an issue, imagine trying to combat dust on the Moon. Dust is a significant challenge for astronauts living and working on the lunar surface. So, NASA is developing technologies that mitigate dust buildup enabling a safer, sustainable presence on the Moon. A flight test aboard a suborbital rocket system that will simulate lunar gravity is the next step in understanding how dust mitigation technologies can successfully address this challenge. During the flight test with Blue Origin, seven technologies developed by NASA’s Game Changing Development program within the agency’s Space Technology Mission Directorate will study regolith mechanics and lunar dust transport in a simulated lunar gravity environment. To view this video please enable JavaScript, and consider upgrading to a web browser that supports HTML5 video The technologies featured in this animation are Electrostatic Dust Lofting (EDL), Electrodynamic Regolith Conveyor (ERC), Hermes Lunar-G, ISRU Pilot Excavator (IPEx), Clothbot, Duneflow, and Vertical Lunar Regolith Conveyor (VLRC). Each of these technology payloads will advance our understanding of regolith mechanics and lunar dust transport through flight testing in space with simulated lunar gravity.NASA / Advanced Concepts Lab Why Is Lunar Dust a Problem? With essentially no atmosphere, dust gets lofted, or lifted by the surface, by a spacecraft’s plumes as it lands on the lunar surface. But it can also be lofted through electrostatic charges. Lunar dust is electrostatic and ferromagnetic, meaning it adheres to anything that carries a charge. Kristen John, NASA’s Lunar Surface Innovation Initiative technical integration lead at Johnson Space Center said, “The fine grain nature of dust contains particles that are smaller than the human eye can see, which can make a contaminated surface appear to look clean.” Although lunar dust can appear smooth with a powder like finish, its particles actually have a jagged shape. Lunar dust can scratch everything from a spacesuit to human lungs. Dust can also prevent hardware from surviving the lunar night when it accumulates on solar panels causing a reduction in available power. A buildup of dust coats thermal radiators, increasing the temperature of the equipment. Lunar dust can also accumulate on windows, camera lenses, and visors leading to obscured vision. Dirty Moon? Clean It Up. The projects being tested on the lunar gravity flight with Blue Origin include ClothBot, Electrostatic Dust Lofting (EDL), and Hermes Lunar-G. ClothBot When future astronauts perform extra-vehicular activities on the lunar surface they could bring dust into pressurized, habitable areas. The goal of the ClothBot experiment is to mimic and measure the transport of lunar dust as releases from a small patch of spacesuit fabric. When agitated by pre-programmed motions, the compact robot can simulate “doffing,” the movement that occurs when removing a spacesuit. A laser-illuminated imaging system will capture the dust flow in real-time, while sensors record the size and number of particles traveling through the space. This data will be used to understand dust generation rates inside a lander or airlock from extra-vehicular activity and refine models of lunar dust transport for future lunar and potential Martian missions. Electrostatic Dust Lofting This technology will examine the lofting of lunar dust when electrostatic charging occurs after exposure to ultraviolet light. The EDL’s camera with associated lights will record and illuminate for the duration of the flight. During the lunar gravity phase of the flight, a vacuum door containing the dust sample will release and the ultraviolet light source will illuminate the substance, charging the grains until they electrostatically repel one another and become lofted. The lofted dust will pass through a sheet laser as it rises up from the surface. When the lunar gravity phase ends, the ultraviolet light source disables, and the camera will continue recording until the end of the flight. This data will inform dust mitigation modeling efforts for future Moon missions. Hermes Lunar-G NASA partnered with Texas A&M and Texas Space Technology Applications and Research (T STAR) to develop Hermes Lunar-G, technology that utilizes flight-proven hardware to conduct experiments with regolith simulants. Hermes was previously a facility on the International Space Station. Hermes Lunar-G repurposed Hermes hardware to study lunar regolith simulants. The Hermes Lunar-G technology uses four canisters to compress the simulants during flight, takeoff, and landing. When the technology is in lunar gravity, it will decompress the contents of the canisters while high-speed imagery and sensors capture data. Results of this experiment will provide information on regolith mechanics that can be used in a variety of computational models. The results of Hermes Lunar-G will be compared to microgravity data from the space station as well as similar data acquired from parabolic flights for lunar and microgravity flight profiles. The Future of Dust Mitigation As a primary challenge of lunar exploration, dust mitigation influences several NASA technology developments. Capabilities from In-Situ Resource Utilization to surface power and mobility, rely on some form of dust mitigation, making it a cross-cutting area. Learning some of the fundamental properties of how lunar dust behaves and how lunar dust impacts systems has implications far beyond dust mitigation and environments. Advancing our understanding of the behavior of lunar dust and advancing our dust mitigation technologies benefits most capabilities planned for use on the lunar surface." Kristen John NASA’s Lunar Surface Innovation Initiative Technical Integration Lead Engineering teams perform a variety of tests to mitigate dust, ensuring it doesn’t cause damage to hardware that goes to the Moon. NASA’s Game Changing Development program, created a reference guide for lunar dust mitigation to help engineers build hardware destined for the lunar surface. NASA’s Flight Opportunities program funded the Blue Origin flight test as well as the vehicle capability enhancements to enable the simulation of lunar gravity during suborbital rocket flight for the first time. The payloads are managed under NASA’s Game Changing Development program within the agency’s Space Technology Mission Directorate.

An artist’s concept of the Earth, Moon, and Mars.Credit: NASA As NASA develops a blueprint for space exploration throughout the solar system for the benefit of humanity, the agency released several new documents Friday updating its Moon to Mars architecture. The roadmap sets NASA on course for long-term lunar exploration under the Artemis campaign in preparation for future crewed missions to Mars. Following an Architecture Concept Review, the 2024 updates include a revision of NASA’s Architecture Definition Document which details technical approaches and processes of the agency’s exploration plans, an executive overview, and 12 new white papers on key Moon to Mars topics. “NASA’s Architecture Concept Review process is critical to getting us on a path to mount a human mission to Mars,” said NASA Associate Administrator Jim Free. “We’re taking a methodical approach to mapping out the decisions we need to make, understanding resource and technological trades, and ensuring we are listening to feedback from stakeholders.”   One newly released white paper highlights NASA’s decision to use fission power as the primary source of power on the Martian surface to sustain crews — the first of seven key decisions necessary for human Mars exploration. Fission power is a form of nuclear power unaffected by day and night cycles or potential dust storms on Mars. New additions this year also include a broader, prioritized list of key architecture decisions that need to be made early in NASA’s plans to send humans to the Red Planet. Two new elements are now part of the agency’s Moon to Mars architecture — a lunar surface cargo lander and an initial lunar surface habitat. The lunar surface cargo lander will deliver logistics items, science and technology payloads, communications systems, and more. The initial surface habitat will house astronauts on the lunar surface to extend the crew size, range, and duration of exploration missions and enable crewed and uncrewed science opportunities. The newest revision of the Architecture Definition Document adds more information about NASA’s decision road mapping process — how the agency decides which decisions must be made early in the planning process based on impacts to subsequent decisions — and a list of architecture-driven opportunities that help technology development organizations prioritize research into new technologies that will enable the Moon to Mars architecture. “Identifying and analyzing high-level architecture decisions are the first steps to realizing a crewed Mars exploration campaign,” said Catherine Koerner, associate administrator, Exploration Systems Development Mission Directorate, NASA Headquarters in Washington. “Each yearly assessment cycle as part of our architecture process is moving us closer to ensuring we have a well thought out plan to accomplish our exploration objectives.” NASA’s Moon to Mars architecture approach incorporates feedback from U.S. industry, academia, international partners, and the NASA workforce. The agency typically releases a series of technical documents at the end of its annual analysis cycle, including an update of the Architecture Definition Document and white papers that elaborate on frequently raised topics.  Under NASA’s Artemis campaign, the agency will establish the foundation for long-term scientific exploration at the Moon, land the next Americans and first international partner astronaut on the lunar surface, and prepare for human expeditions to Mars for the benefit of all.  For NASA’s Moon to Mars architecture documents, visit:  https://www.nasa.gov/moontomarsarchitecture -end- Rachel Kraft / Kathryn Hambleton Headquarters, Washington 202-358-1600 rachel.h.kraft@nasa.gov / kathryn.a.hambleton@nasa.gov Share Details Last Updated Dec 13, 2024 EditorJessica TaveauLocationNASA Headquarters Related TermsExploration Systems Development Mission DirectorateArtemisEarth's MoonMars View the full article

ESA/Hubble & NASA, A. Riess, D. Thilker, D. De Martin (ESA/Hubble), M. Zamani (ESA/Hubble) This NASA/ESA Hubble Space Telescope image features the glorious spiral galaxy NGC 5643, which is located roughly 40 million light-years away in the constellation Lupus, the Wolf. NGC 5643 is a grand design spiral, which refers to the galaxy’s symmetrical form with two large, winding spiral arms that are clearly visible. Bright-blue stars define the galaxy’s spiral arms, along with lacy reddish-brown dust clouds and pink star-forming regions. As fascinating as the galaxy appears at visible wavelengths, some of NGC 5643’s most interesting features are invisible to the human eye. Ultraviolet and X-ray images and spectra of NGC 5643 show that the galaxy hosts an active galactic nucleus: an especially bright galactic core powered by a feasting supermassive black hole. When a supermassive black hole ensnares gas from its surroundings, the gas collects in a disk that heats up to hundreds of thousands of degrees. The superheated gas shines brightly across the electromagnetic spectrum, but especially at X-ray wavelengths. NGC 5643’s active galactic nucleus isn’t the brightest source of X-rays in the galaxy, though. Researchers using ESA’s XMM-Newton discovered an even brighter X-ray-emitting object, called NGC 5643 X-1, on the galaxy’s outskirts. What could be a more powerful source of X-rays than a supermassive black hole? Surprisingly, the answer appears to be a much smaller black hole! While the exact identity of NGC 5643 X-1 is unknown, evidence points to a black hole that is about 30 times more massive than the Sun. Locked in an orbital dance with a companion star, the black hole ensnares gas from its stellar companion, creating a superheated disk that outshines the NGC 5643’s galactic core. NGC 5643 was also the subject of a previous Hubble image. The new image incorporates additional wavelengths of light, including the red color that is characteristic of gas heated by massive young stars.

ESA/Hubble & NASA, R. Windhorst, W. Keel This NASA/ESA Hubble Space Telescope image features a spiral galaxy, named UGC 10043. We don’t see the galaxy’s spiral arms because we are seeing it from the side. Located roughly 150 million light-years from Earth in the constellation Serpens, UGC 10043 is one of the somewhat rare spiral galaxies that we see edge-on. This edge-on viewpoint makes the galaxy’s disk appear as a sharp line through space, with its prominent dust lanes forming thick bands of clouds that obscure our view of the galaxy’s glow. If we could fly above the galaxy, viewing it from the top down, we would see this dust scattered across UGC 10043, possibly outlining its spiral arms. Despite the dust’s obscuring nature, some active star-forming regions shine out from behind the dark clouds. We can also see that the galaxy’s center sports a glowing, almost egg-shaped ‘bulge’, rising far above and below the disk. All spiral galaxies have a bulge similar to this one as part of their structure. These bulges hold stars that orbit the galactic center on paths above and below the whirling disk; it’s a feature that isn’t normally obvious in pictures of galaxies. The unusually large size of this bulge compared to the galaxy’s disk is possibly due to UGC 10043 siphoning material from a nearby dwarf galaxy. This may also be why its disk appears warped, bending up at one end and down at the other. Like most full-color Hubble images, this image is a composite, made up of several individual snapshots taken by Hubble at different times, each capturing different wavelengths of light. One notable aspect of this image is that the two sets of data that comprise this image were collected 23 years apart, in 2000 and 2023! Hubble’s longevity doesn’t just afford us the ability to produce new and better images of old targets; it also provides a long-term archive of data which only becomes more and more useful to astronomers.
