The Marshall Star for March 20, 2024

NASA technologist Les Johnson, on stage, discusses how the solar sail can use solar propulsion to travel farther in space than anyone has traveled before during an exhibit held March 12 at the U.S. Space & Rocket Center.

Marshall Technologist Talks Solar Sail Technology in Rocket Center Exhibit

By Jessica Barnett

Space enthusiasts at the U.S. Space & Rocket Center were treated to a special exhibit featuring technologist Les Johnson of NASA’s Marshall Space Flight Center and a look at the future of solar sail technology.

Johnson shared the latest updates on the solar sail technology through brief presentations onstage in the Rocket Center’s atrium as well as one-on-one interactions with museum guests at the various displays set up near the stage. He discussed how the technology will work, showed a video of the solar sail team testing one of the sail’s four quadrants, and discussed what it could mean for the future of space exploration.

“I’m excited about this type of propulsion, because it’s free, it doesn’t run out of fuel, and you can use it to do amazing things in the future,” Johnson said. “We could build really big sails – 10 to 100 times bigger than the Solar Cruiser sail – and instead of using sunlight, we could shine lasers on it and go out in the solar system, literally where we’ve never been before.”

NASA continues to unfurl plans for solar sail technology as a promising method of deep space transportation. The agency cleared a key technology milestone in January with one of four identical solar sail quadrants successfully deploying. Together, the solar sail quadrants will make up the 17,800-square-foot sail.

Marshall leads the solar sail team, which includes Florida-based Redwire Corporation as prime contractor and Huntsville-based NeXolve as subcontractor.

NASA Lights ‘Beacon’ on Moon with Autonomous Navigation System Test

By Rick Smith

For 30 total minutes in February, NASA lit a beacon on the Moon – successfully testing a sophisticated positioning system that will make it safer for Artemis-era explorers to visit and establish a permanent human presence on the lunar surface.

A man sits in front of a computer screen in a large control room with huge screens in the background.
Evan Anzalone, at lower left, principal investigator for the Lunar Node-1 demonstrator payload, monitors the LN-1 mission from the Lunar Utilization Control Area in the Huntsville Operations Support Center at NASA’s Marshall Space Flight Center. LN-1 successfully tested an autonomous navigation and geo-positioning system that will make Artemis-era lunar explorers safer as they work to establish a permanent human presence on the lunar surface.
NASA

The Lunar Node 1 demonstrator, or LN-1, is an autonomous navigation system intended to provide a real-time, point-to-point communications network on the Moon. The system – tested during Intuitive Machines’ IM-1 mission as part of NASA’s CLPS (Commercial Lunar Payload Services) initiative – could link orbiters, landers, and even individual astronauts on the surface, digitally verifying each explorer’s position relative to other networked spacecraft, ground stations, or rovers on the move.

That system would be a marked improvement over conventional, Earth-based radio data relays, NASA researchers said – even more so compared to Apollo-era astronauts trying to “eyeball” distance and direction on the vast, mostly grey lunar surface.

“We’ve lit a temporary beacon on the lunar shore,” said Evan Anzalone, LN-1 principal investigator at NASA’s Marshall Space Flight Center. “Now, we seek to deliver a sustainable local network – a series of lighthouses that point the way for spacecraft and ground crews to safely, confidently spread out and explore.”

The experiment was launched Feb. 15 as a payload on the IM-1 mission. The Nova-C lander, named Odysseus, successfully touched down Feb. 22 near Malapert A, a lunar impact crater near the Moon’s South Pole region, executing the first American commercial uncrewed landing on the Moon. The lander spent its subsequent days on the surface conducting six science and technology demonstrations, among them LN-1, before it officially powered down on Feb. 29.

“This feat from Intuitive Machines, SpaceX, and NASA demonstrates the promise of American leadership in space and the power of commercial partnerships under NASA’s CLPS initiative,” NASA Administrator Bill Nelson said in a statement after the landing. “Further, this success opens the door for new voyages under Artemis to send astronauts to the Moon, then on to Mars.” 

During IM-1’s translunar journey, the Marshall team conducted daily tests of the LN-1 beacon. The original plan was for the payload to transmit its beacon around the clock upon landing. NASA’s Deep Space Networkthe international giant radio antenna array, would have received that signal for, on average, 10 hours daily.

Instead, due to the lander’s touchdown orientation, LN-1 conducted two 15-minute transmissions from the surface. DSN assets successfully locked on the signal, feeding telemetry, navigation measurements, and other data to researchers at Marshall, NASA’s Jet Propulsion Laboratory, and Morehead State University in Morehead, Kentucky. The team continues to evaluate the data.

LN-1 even provided critical backup to IM-1’s onboard navigation system, noted Dr. Susan Lederer, CLPS project scientist at NASA’s Johnson Space Center. The LN-1 team “really stepped up to the task,” she said, by relaying spacecraft positioning data during translunar flight to NASA’s Deep Space Network satellites at the Goldstone and Madrid Deep Space Communications Complexes in Fort Irwin, California, and Robledo de Chavela, Spain, respectively.

This image from the lander’s narrow-field-of-view camera was retrieved on Feb. 27. It shows spacecraft hardware in the foreground, and the gaping maw of a 2-billion-year-old lunar crater beyond. It’s approximately 500 meters to the near lip of the crater, and another 500 meters to its far side. Inky black space extends above the horizon.

Intuitive Machines

In time, navigation aids such as Lunar Node-1 could be used to augment navigation and communication relays and surface nodes, providing increased robustness and capability to a variety of users in orbit and on the surface.

As the lunar infrastructure expands, Anzalone envisions LN-1 evolving into something akin to a network that monitors and maintains a busy metropolitan subway system, tracking every “train” in real time, and operating as one part of a larger, LunaNet-compatible architecture, augmenting other NASA and international investments, including the Japanese Aerospace Exploration Agency’s Lunar Navigation Satellite System.

And the technology promises even greater value to NASA’s Moon to Mars efforts, he said. LN-1 may improve data delivery to lunar explorers by just a matter of seconds over conventional relays – but real-time navigation and positioning becomes much more vital on Mars, where transmission delays from Earth can take up to 20 minutes.

“That’s a very long time to wait for a spacecraft pilot making a precision orbital adjustment, or humans traversing uncharted Martian landscapes,” Anzalone said. “LN-1 can make lighthouse beacons of every explorer, vehicle, temporary or long-term camp, and site of interest we send to the Moon and to Mars.”

Marshall engineers designed, developed, integrated, and tested LN-1 as part of the NPLP (NASA-Provided Lunar Payloads) project funded by the agency’s Science Mission Directorate. Marshall also developed MAPS (Multi-spacecraft Autonomous Positioning System), the underlying networked computer navigation software. MAPS previously was tested on the International Space Station in 2018, using NASA’s Space Communications and Navigations (SCaN) Testbed.

NASA Artemis Mission Progresses with SpaceX Starship Test Flight

As part of NASA’s Artemis campaign to return humans to the Moon for the benefit of all, the agency is working with SpaceX to develop the company’s Starship human landing system (HLS), which will land astronauts near the Moon’s South Pole during the Artemis III and Artemis IV missions. On March 14, SpaceX launched the third integrated flight test of its Super Heavy booster and Starship upper stage, an important milestone toward providing NASA with a Starship HLS for its Artemis missions.

SpaceX launched the third integrated flight test of its Super Heavy booster and Starship upper stage from the company’s Starbase orbital launch pad at 8:25 a.m. CT on March 14. This flight test is an important milestone toward providing NASA with a Starship HLS for its Artemis missions.

A complement of 33 Raptor engines, fueled by super-cooled liquid methane and liquid oxygen, powered the Super Heavy booster with Starship stacked on top, from the company’s Starbase orbital launch pad at 8:25 a.m. CDT. Starship, using six Raptor engines, separated from the Super Heavy booster employing a hot-staging technique to fire the engines before separation at approximately three minutes into the flight, in accordance with the flight plan. This was the third flight test of the integrated Super Heavy-Starship system.

“With each flight test, SpaceX attempts increasingly ambitious objectives for Starship to learn as much as possible for future mission systems development. The ability to test key systems and processes in flight scenarios like these integrated tests allows both NASA and SpaceX to gather crucial data needed for the continued development of Starship HLS,” said Lisa Watson-Morgan, HLS Program Manager at NASA’s Marshall Space Flight Center.

This test accomplished several important firsts that will contribute to the development of Starship for Artemis lunar landing missions. The spacecraft reached its expected orbit and Starship completed the full-duration ascent burn.

One objective closely tied to future Artemis operations is the transfer of thousands of pounds of cryogenic propellant between internal tanks during the spacecraft’s coast phase as part of NASA’s Space Technology Missions Directorate 2020 Tipping Point awards. The propellant transfer demonstration operations were completed, and the NASA-SpaceX team is currently reviewing the flight data that was received. This Tipping Point technology demonstration is one of more than 20 development activities NASA is undertaking to solve the challenges of using cryogenic fluids during future missions.

As a key step toward understanding how super-cooled propellant sloshes within the tanks when the engines shut down, and how that movement affects Starship’s stability while in orbit, engineers will study flight test data to assess the performance of thrusters that control Starship’s orientation in space. They are also interested to learn more about how the fluid’s movement within the tanks can be settled to maximize propellant transfer efficiency and ensure Raptor engines receive needed propellant conditions to support restart in orbit.

“Storing and transferring cryogenic propellant in orbit has never been attempted on this scale before,” said Jeremy Kenny, project manager, NASA’s Cryogenic Fluid Management Portfolio at Marshall. “But this is a game-changing technology that must be developed and matured for science and exploration missions at the Moon, Mars, and those that will venture even deeper into our solar system.”

Under NASA’s Artemis campaign, the agency will land the first woman, first person of color, and its first international partner astronaut on the lunar surface and prepare for human expeditions to Mars. Commercial human landing systems are critical to deep space exploration, along with the Space Launch System rocket, Orion spacecraft, advanced spacesuits and rovers, exploration ground systems, and the Gateway space station.

Evolved Adapter for Future NASA SLS Flights Readied for Testing

A test article of the universal stage adapter for NASA’s more powerful version of its SLS (Space Launch System) rocket arrived to Building 4619 at NASA’s Marshall Space Flight Center on Feb. 22 from Leidos in Decatur, Alabama.

A test version of the universal stage adapter for the SLS (Space Launch System) rocket for Artemis 4 is seen inside Marshall Space Flight Center’s facility in Huntsville, Alabama. The adapter sits on a yellow piece of hardware. There is an American flag hanging on the wall to the right and the word “Leidos” is painted black on the white adapter.

The universal stage adapter will connect the rocket’s upgraded in-space propulsion stage, called the exploration upper stage, to NASA’s Orion spacecraft as part of the evolved Block 1B configuration of the SLS rocket. It will also serve as a compartment capable of accommodating large payloads, such as modules or other exploration spacecraft. The SLS Block 1B variant will debut on Artemis IV and will increase SLS’s payload capability to send more than 84,000 pounds to the Moon in a single launch.

In Building 4619’s Load Test Annex High Bay at Marshall, the development test article will first undergo modal testing that will shake the hardware to validate dynamic models. Later, during ultimate load testing, force will be applied vertically and to the sides of the hardware. Unlike the flight hardware, the development test article has flaws intentionally included in its design, which will help engineers verify that the adapter can withstand the extreme forces it will face during launch and flight.

The test article joins an already-rich history of rocket hardware that has undergone high-and-low pressure, acoustic, and extreme temperature testing in the multipurpose, high-bay test facility; it will be tested in the same location that once bent, compressed, and torqued the core stage intertank test article for SLS rocket’s Block 1 configuration. Leidos, the prime contractor for the universal stage adapter, manufactured the full-scale prototype at its Aerospace Structures Complex in Decatur.

NASA is working to land the first woman, first person of color, and its first international partner astronaut on the Moon under Artemis. SLS is part of NASA’s backbone for deep space exploration, along with the Orion spacecraft and Gateway in orbit around the Moon and commercial human landing systems, next-generational spacesuits, and rovers on the lunar surface. SLS is the only rocket that can send Orion, astronauts, and supplies to the Moon in a single launch.

NASA Study: Asteroid’s Orbit, Shape Changed After DART Impact

When NASA’s DART (Double Asteroid Redirection Test) deliberately smashed into a 560-foot-wide asteroid on Sept. 26, 2022, it made its mark in more ways than one. The demonstration showed that a kinetic impactor could deflect a hazardous asteroid should one ever be on a collision course with Earth. Now a new study published in the Planetary Science Journal shows the impact changed not only the motion of the asteroid, but also its shape.

The asteroid Dimorphos was captured by NASA’s DART mission just two seconds before the spacecraft struck its surface on Sept. 26, 2022. Observations of the asteroid before and after impact suggest it is a loosely packed “rubble pile” object.

DART’s target, the asteroid Dimorphos, orbits a larger near-Earth asteroid called Didymos. Before the impact, Dimorphos had a roughly symmetrical “oblate spheroid” shape – like a squashed ball that is wider than it is tall. With a well-defined, circular orbit at a distance of about 3,900 feet from Didymos, Dimorphos took 11 hours and 55 minutes to complete one loop around Didymos.

“When DART made impact, things got very interesting,” said Shantanu Naidu, a navigation engineer at NASA’s Jet Propulsion Laboratory in Southern California, who led the study. “Dimorphos’ orbit is no longer circular: Its orbital period” – the time it takes to complete a single orbit – “is now 33 minutes and 15 seconds shorter. And the entire shape of the asteroid has changed, from a relatively symmetrical object to a ‘triaxial ellipsoid’ – something more like an oblong watermelon.”

Naidu’s team used three data sources in their computer models to deduce what had happened to the asteroid after impact. The first source was aboard DART: The spacecraft captured images as it approached the asteroid and sent them back to Earth via NASA’s Deep Space Network (DSN). These images provided close-up measurements of the gap between Didymos and Dimorphos while also gauging the dimensions of both asteroids just prior to impact.

The second data source was the DSN’s Goldstone Solar System Radar, located near Barstow, California, which bounced radio waves off both asteroids to precisely measure the position and velocity of Dimorphos relative to Didymos after impact. Radar observations quickly helped NASA conclude that DART’s effect on the asteroid greatly exceeded the minimum expectations.

The third and most significant source of data: ground telescopes around the world that measured both asteroids’ “light curve,” or how the sunlight reflecting off the asteroids’ surfaces changed over time. By comparing the light curves before and after impact, the researchers could learn how DART altered Dimorphos’ motion.

As Dimorphos orbits, it periodically passes in front of and then behind Didymos. In these so-called “mutual events,” one asteroid can cast a shadow on the other, or block our view from Earth. In either case, a temporary dimming – a dip in the light curve – will be recorded by telescopes.

See the DART impact with NASA’s Eyes on the Solar System.

“We used the timing of this precise series of light-curve dips to deduce the shape of the orbit, and because our models were so sensitive, we could also figure out the shape of the asteroid,” said Steve Chesley, a senior research scientist at JPL and study co-author. The team found Dimorphos’ orbit is now slightly elongated, or eccentric. “Before impact,” Chesley continued, “the times of the events occurred regularly, showing a circular orbit. After impact, there were very slight timing differences, showing something was askew. We never expected to get this kind of accuracy.”

This illustration shows the approximate shape change that the asteroid Dimorphos experienced after DART hit it. Before impact, left, the asteroid was shaped like a squashed ball; after impact it took on a more elongated shape, like a watermelon.

The models are so precise, they even show that Dimorphos rocks back and forth as it orbits Didymos, Naidu said.

The team’s models also calculated how Dimorphos’ orbital period evolved. Immediately after impact, DART reduced the average distance between the two asteroids, shortening Dimorphos’ orbital period by 32 minutes and 42 seconds, to 11 hours, 22 minutes, and 37 seconds.

Over the following weeks, the asteroid’s orbital period continued to shorten as Dimorphos lost more rocky material to space, finally settling at 11 hours, 22 minutes, and 3 seconds per orbit – 33 minutes and 15 seconds less time than before impact. This calculation is accurate to within 1 ½ seconds, Naidu said. Dimorphos now has a mean orbital distance from Didymos of about 3,780 feet – about 120 feet closer than before impact.

“The results of this study agree with others that are being published,” said Tom Statler, lead scientist for solar system small bodies at NASA Headquarters. “Seeing separate groups analyze the data and independently come to the same conclusions is a hallmark of a solid scientific result. DART is not only showing us the pathway to an asteroid-deflection technology, it’s revealing new fundamental understanding of what asteroids are and how they behave.”

These results and observations of the debris left after impact indicate that Dimorphos is a loosely packed “rubble pile” object, similar to asteroid Bennu. ESA’s (European Space Agency) Hera mission, planned to launch in October 2024, will travel to the asteroid pair to carry out a detailed survey and confirm how DART reshaped Dimorphos.

DART was designed, built, and operated by the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, for NASA’s Planetary Defense Coordination Office, which oversees the agency’s ongoing efforts in planetary defense. The mission is a project of the agency’s Planetary Mission Program Office, which is at NASA’s Marshall Space Flight Center. DART was humanity’s first mission to intentionally move a celestial object.

JPL, a division of Caltech in Pasadena, California, manages the DSN for NASA’s Space Communications and Navigation (SCaN) program within the Space Operations Mission Directorate at the agency’s headquarters.

      Gator Speaks
      The news in September about the historic NASA Stennis ASTRA (Autonomous Satellite Technology for Resilient Applications) payload mission brings wonderful encouragement to this ‘ol Gator!
      Gator SpeaksNASA/Stennis I know great potential when I see it, and the continuation of the center’s first-ever in-space autonomous systems payload mission aboard an orbiting satellite with Sidus Space, Inc. has just that.
      The historic mission highlights the can-do attitude shared by all at NASA Stennis.
      The center has a storied history of pushing the boundaries for what is possible. If there is a way to get something done, the folks at NASA Stennis will discover it.
      ASTRA is no different and represents a first in this particular space (pun intended!) of autonomous systems work at NASA Stennis.
      This is a first step toward fulfilling part of the center’s strategic plan to design autonomous systems to help accelerate the development of intelligent aerospace systems and services for government and industry.
      Such work could contribute to enhanced efficiency, improved safety, scalability to meet demands, and much more. The potential is ASTRA-nomical. See what I did there?
      Potential is not developed over night, which makes ASTRA even more intriguing. The mission could run for up to four years while gathering valuable data along the way.
      The ASTRA mission is an exciting leap forward for NASA Stennis to learn what is possible and perhaps open doors for a future that unlocks new frontiers.
      One thing this Gator has learned to be true is the brighter the future, the more we must believe in ourselves, and I believe in the NASA Stennis Autonomous Systems Laboratory team.

      Looking Back: A First for Women in Space
      Forty years ago this month, NASA demonstrated in real time that there is space for everybody. An image from Oct. 11, 1984, shows astronaut Kathryn D. Sullivan checking the latch of an antenna in the space shuttle Challenger’s open cargo during her historic extravehicular activity (spacewalk). The 13th flight of the Space Shuttle Program, STS-41G, was the first flight to include two women, Sullivan and Sally Ride. Ride has become the first American woman to fly to space in June 1983. A little more than a year later, Sullivan became the first American woman to walk in space. NASA’s Stennis Space Center near Bay St. Louis, Mississippi, tested space shuttle main engines for 34 years, from 1975 to 2009. The testing included hot fires of the flight engines that helped power this historic moment. To honor this time in space history, watch Space for Women on the agency’s new streaming platform – NASA+. The film features interviews with NASA employees and shows the variety of positions held by women in the agency.NASA The official portrait of Astronaut Kathryn D. Sullivan from 1984.

      The Fabric of Marshall: Center Hosts Safety Day 2024
      By Serena Whitfield
      “Safety Woven Throughout the Fabric of Marshall” was the theme for Safety Day at NASA’s Marshall Space Flight Center on Sept. 26.
      Kickoff activities were held in Building 4316 and other sites around the center.
      “It is crucial to ensure that each of us weaves safety into everything we do, not only at work, but in our daily lives,” Marshall Director Joseph Pelfrey said.
      NASA Marshall Space Flight Center Director Joseph Pelfrey, left, with NASA astronaut Mark T. Vande Hei, who was the keynote speaker for Marshall’s Safety Day on Sept. 26. NASA/Krisdon Manecke NASA started the Safety Day tradition following the space shuttle Columbia accident in 2003. Centers across the agency dedicate a day each year for team members to pause and reflect on keeping the work environment safe. 
      This year’s Safety Day began with a breakfast for employees, which was sponsored by Jacobs and Bastion Technologies. After breakfast, Bill Hill, director of the Safety and Mission Assurance Directorate at Marshall, welcomed center team members before introducing Pelfrey.
      “Over the past year, Marshall’s leadership and workforce have highlighted that transparency is an essential cultural attribute of our workforce and center,” Pelfrey said. “It is also important to our core value of safety. Transparency fosters an environment where employees feel comfortable in reporting potential risks or safety concerns without fear of retribution. This openness ensures that issues are addressed early. It builds trust and accountability within our workforce, center, NASA, and external stakeholders.”
      NASA astronaut Mark T. Vande Hei talks about his time in space aboard the International Space Station. NASA/Krisdon Manecke Guest speaker Marceleus Venable, a purpose coach, trainer, and author, followed Pelfrey’s remarks, telling team members to be safe by taking care of their physical and mental health. He encouraged them to take the time to pat themselves on the back for all their hard work and to appreciate their fellow workers at Marshall.
      NASA astronaut Mark T. Vande Hei was the keynote speaker, encouraging employees to be team players in NASA’s safety mission.
      “We need a lot of talented team players to meet the challenges that we have for future space flights,” said Vande Hei, who was selected as a NASA astronaut in 2009 and most recently served as a flight engineer on the International Space Station as part of Expedition 65 and 66. “Always try to do your best, but make sure that other people around you are doing their best as well and help them do that rather than you standing out as always being the best.”
      Peter Wreschinsky, second from left, a Jacobs Space Exploration Group employee, is presented with the Golden Eagle Award during Safety Day. He is joined by his wife, Terri. They are joined by Bill Hill, left, director of the Safety and Mission Assurance Directorate at Marshall, and Jeff Haars, right, Jacobs vice president. The Golden Eagle Award is a part of the Mission Success is in Our Hands initiative, a collaboration between Marshall and Jacobs. Wreschinsky was recognized with the award for voicing concern about a valve impacted by corrosion on the Commercial Crew Program Crew-8 Dragon Capsule. The valve and several others were subsequently replaced. NASA/Serena Whitfield Micah Embry, the Safety Day 2024 chairperson, presented Vande Hei with a certificate for his participation. 
      Also during the event, Hill awarded the Golden Eagle Award to Peter Wreschinsky, a Jacobs Space Exploration Group employee. The award is part of the Mission Success is in Our Hands safety initiative, a collaboration between Marshall and Jacobs.
      More than 400 civil servants and contractors participated in Safety Day, with organizational and vender booths providing information to employees across a variety of safety topics, including Emergency Management Services, fire protection, storm shelters, and more.
      “As Marshall continues to be a leader at NASA and across the aerospace industry, … we must always be looking forward to improve our procedures and anticipate potential hazards,” Pelfrey said. “Safety is directly tied to our mission success. Without safety, we cannot achieve the goals we set for ourselves in space exploration, research, and innovation.”
      Whitfield is an intern supporting the Marshall Office of Communications.

      Human Lander System Spotlight: Preparing for the First Crewed Lunar Landings for Artemis
      The featured business unit for the month of September at NASA’s Marshall Space Flight Center was Lander Systems. Marshall leads the development of the systems needed to safely land humans on the Moon and, eventually Mars. This includes the Human Landing System Program (HLS), which manages the development of commercial lunar landing systems that will transport astronauts to and from the surface of the Moon as part of the agency’s Artemis campaign.
      For Artemis III and Artemis IV, NASA has selected SpaceX’s Starship HLS, while Blue Origin’s Blue Moon lander will be used for Artemis V. Having two distinct lunar lander designs, with different approaches to how they meet NASA’s mission needs, provides more robustness while ensuring a regular cadence of Moon landings.
      NASA works closely with its industry partners to mature the landers, exercising insight and offering collaboration to ensure astronaut safety and mission success. Through Artemis, NASA aims to land the first woman, first person of color, and first international partner astronaut on the lunar surface while advancing key science and discovery for the benefit of all.
      Learn more about HLS and meet some of the NASA Marshall teammates below who are working on the lunar landers:
      Amy BuckNASA/Ken Hall Amy Buck has been working with Artemis systems since she first came to Marshall 10 years ago. Previously part of the cryogenic insulation team for the SLS (Space Launch System) rocket, Buck is now the materials discipline lead for HLS. In her role, she has the chance to work on nearly every piece of hardware for the two landers as she and her team work with each of the HLS providers to ensure compliance with NASA’s requirements.
      “The NASA HLS materials team is vital in supporting the design, testing, and manufacturing of the landers,” Buck said. “Landing on the Moon is central to the larger Artemis mission, and I’m super excited to be part of the Artemis Generation.”
      Buck is most excited to see the first woman land on the Moon under Artemis and says she hopes it will inspire young girls – the next generation of engineers and scientists – to go into science and engineering.
      Sean UnderwoodNASA/Ken Hall Mission success is all in the details for Sean Underwood, the thermal discipline lead for HLS. The Georgia native works with a team responsible for ensuring that the lunar landers can operate in the Moon’s harsh environment.
      “There are unique thermal challenges associated with the Artemis III, IV, and V missions,” Underwood said. “Our primary objective is to manage thermal energy and heating rates, ensuring that HLS components and systems remain within thermal limits across all mission environments.”
      Underwood joined Marshall in 2020 and sees his role with Artemis as one that will shape the future of space exploration – and Marshall. “Marshall Space Flight Center has been at the forefront of monumental space projects since its inception,” he said. “Through Artemis, we are ensuring that the legacy of past missions continues to inspire and drive us forward.”

      Innovative Thermal Energy Storage Tanks Keep Marshall Cool – and Save Taxpayer Dollars
      By Rick Smith
      As any home or business owner in the Southern United States knows, maintaining energy costs while trying to keep cool in the sweltering summer months is no simple challenge.
      But one “cool” new infrastructure upgrade at NASA’s Marshall Space Flight Center will reduce the center’s utility costs by approximately $250,000 a year, shrinking Marshall’s environmental footprint and streamlining long-term infrastructure maintenance costs.
      NASA Marshall Space Flight Center facilities engineers Connor McLean, left, and Angela Bell assess the readiness of Marshall’s new thermal energy storage tank, which officially goes into operation in October. The tank stands alongside Marshall’s original thermal tank outside Building 4473, where they chill and store water to cool off laboratories, offices, and other buildings during the hot summer months. McLean and Bell lead the tank project on behalf of Marshall’s Office of Center Operations. NASA/Charles Beason It’s called a thermal energy storage tank – 60 feet high, 60 feet in diameter, each unit capable of holding approximately 1.125 million gallons of chilled water – and it represents another milestone for facilities engineers in Marshall’s Office of Center Operations, whose tactics have already reduced center-wide energy expenditure by a dizzying 58.3% since fiscal year 2003.
      Thermal energy storage is not a new process; it’s been used for decades to maximize efficiency in temperature control, particularly among industrial facilities and large public venues from hospitals to indoor stadiums. At Marshall, the chilled water serves a critical purpose center-wide, circulating from a central plant via a network of underground pipes to help keep laboratories and other buildings temperate throughout the summer heat.
      “The average team member might not realize it’s chilled water, not just air, that keeps our labs, offices, and test facilities cool,” said Marshall facilities engineer Angela Bell, who helped oversee the installation of the second tank. “Our tanks operate at night, when utility prices drop and there is less overall demand on the regional energy grid, then send the chillwater out during the day.”
      Marshall’s first tank was built and put into operation in 2008-2009. The second officially goes into service in October, joining its counterpart in creating chilled water overnight. Together, the tanks – situated adjacent to Building 4473 on the corner of Morris and Titan roads – provide an annual energy savings of roughly half a million dollars.
      Marshall facilities engineer Connor McLean, who succeeded Bell as project manager for the new tank, noted that each thermal energy storage tank handles approximately 106,000 kilo-BTUs worth of cooling activity per day – or roughly 1,750 times as much cooling capacity as a central air system in a traditional family home.
      Even with that considerable output, Marshall’s original tank had been hard-pressed to keep up with demand across the entire center over the past decade and a half, as climate change steadily pushed temperatures to sustained extremes.
      “This is a huge stride in critical system redundancy,” McLean said. “Having the second tank enables us to run both concurrently or give one of them some necessary downtime without loss of center-wide functionality. That added capability makes Marshall more resilient and bolsters our confidence in our ability to handle unforeseen challenges.”
      The electricity that powers the storage tanks is a mix – hydroelectric, fossil fuels, nuclear, and an increasing amount of renewable energy sources – provided by the Tennessee Valley Authority via the U.S. Army, from whom NASA leases property on Redstone Arsenal. 
      “The tanks will be tremendous cost-savers for the next 40-50 years,” Bell said. “They allow us to use energy much more efficiently, based on past energy consumption levels – and that allows Marshall to do other things with those dollars.”
      Over the past 20 years, Marshall has reinvested energy savings and facilities cost underruns back into center operations, often to fund new, cost-saving overhauls: upgrading facility HVAC systems or replacing obsolete lighting with more efficient LEDs.
      “If we didn’t reduce consumption, our projected utility costs would be around $30 million per year,” said Rhonda Truitt, Marshall’s energy and water manager. “Thanks to efficient strategizing, encouraged and championed by Marshall and NASA leadership, we typically operate in the range of just $16-18 million per year.”
      Such strategies have enabled Marshall to effectively keep its infrastructure budget flat since the early 2010s – reducing overall energy consumption and replacing outdated facilities with more cost-conscious, environmentally friendly modern buildings, a program known among facilities engineers as “repair by replacement.”
      The U.S. Army at Redstone doesn’t employ a central chiller plant of its own, but the Marshall facilities team works “very closely” with their counterparts on the military side.
      “We have a great working relationship,” Truitt said. “The real advantage of our system is that by reducing our peak energy demand, it reduces it for all of Redstone – which benefits the rest of the Arsenal and the lower Tennessee Valley.”
      The new tank goes into operation just in time for the start of National Energy Awareness Month in October – and Truitt and her team encourage the Marshall workforce to continue to practice sensible energy conservation tactics even as sweat-inducing temperatures subside.
      “Turn off lights and computer monitors wherever possible, don’t leave doors or windows propped open, and be mindful of all the small things that can add up over time,” Truitt said. “Our goal is always to help team members do their jobs in the most efficient way possible, to accomplish Marshall’s objectives and conserve our energy budget without impeding the mission.”
      Thanks to the center’s new thermal energy storage tank, that should be no sweat.

      Keeping the Pace: Marshall Hosts Annual ‘Racin’ the Station’ Duathlon
      A costumed gorilla pacer leads a group of runners during “Racin’ the Station” duathlon, a run/bike/run event where the participants “raced” the International Space Station. The event was Sept. 28 at NASA’s Marshall Space Flight Center, which is on Redstone Arsenal. “Racin’ the Station” is an annual event where participants try to complete the course faster than it takes the space station to complete one Earth orbit, which is every 91 minutes, 12 seconds. Organizers track the starting location of the space station at the race start, and a costumed pacer keeps up with the station time on the course as a visual marker for participants to stay ahead of.  Before the race, organizers drew a to-scale SLS (Space Launch System) Block 1 rocket in chalk onto the Activities Building parking lot near the race transition area. The opening ceremonies featured a video of the Artemis 1 launch, with the race starting with the launch of a model rocket. “The rain was a first for race day since we started this event in 2012,” said Kent Criswell, race organizer for Marshall. “But we still had a safe race with 106 individuals and 13 relay teams finishing.” The event is organized by the Team Rocket Triathlon Club in Huntsville and by the Marshall Association, a professional employee service organization at the Marshall Center whose members include civil service employees, retirees and contractors. Proceeds from the registration fee for the event go to the Marshall Association scholarship fund. Race results can be found here. (NASA/Charles Beason)

      NASA Seeks Innovators for Lunar Waste Competition 
      By Savannah Bullard 
      A new NASA competition, the LunaRecycle Challenge, is open and offering $3 million in prizes for innovations in recycling material waste on deep space missions. 
      As NASA continues efforts toward long-duration human space travel, including building a sustained human presence on the Moon through its Artemis missions, the agency needs novel solutions for processing inorganic waste streams like food packaging, discarded clothing, and science experiment materials. While previous efforts focused on the reduction of trash mass and volume, this challenge will prioritize technologies for recycling waste into usable products needed for off-planet science and exploration activities.  
      NASA’s LunaRecycle Challenge will incentivize the design and development of energy-efficient, low-mass, and low-impact recycling solutions that address physical waste streams and improve the sustainability of longer-duration lunar missions. Through the power of open innovation, which draws on the public’s ingenuity and creativity to find solutions, NASA can restructure the agency’s approach to waste management, support the future of space travel, and revolutionize waste treatments on Earth, leading to greater sustainability on our home planet and beyond. 
      “Operating sustainably is an important consideration for NASA as we make discoveries and conduct research both away from home and on Earth,” said Amy Kaminski, program executive for NASA’s Prizes, Challenges, and Crowdsourcing program. “With this challenge, we are seeking the public’s innovative approaches to waste management on the Moon and aim to take lessons learned back to Earth for the benefit of all.” 
      NASA’s LunaRecycle Challenge will offer two competition tracks: a Prototype Build track and a Digital Twin track. The Prototype Build Track focuses on designing and developing hardware components and systems for recycling one or more solid waste streams on the lunar surface. The Digital Twin Track focuses on designing a virtual replica of a complete system for recycling solid waste streams on the lunar surface and manufacturing end products. Offering a Digital Twin track further lowers the barrier of entry for global solvers to participate in NASA Centennial Challenges and contribute to agency missions and initiatives.  
      Teams will have the opportunity to compete in either or both competition tracks, each of which will carry its own share of the prize purse. 
      The LunaRecycle Challenge also will address some of the aerospace community’s top technical challenges. In July, NASA’s Space Technology Mission Directorate released a ranked list of 187 technology areas requiring further development to meet future exploration, science, and other mission needs. The results integrated inputs from NASA mission directorates and centers, industry organizations, government agencies, academia, and other interested individuals to help guide NASA’s space technology development and investments. This list and subsequent updates will help inform future Centennial Challenges.  
      The three technological needs that LunaRecycle will address include logistics tracking, clothing, and trash management for habitation; in-space and on-surface manufacturing of parts and products; and in-space and on-surface manufacturing from recycled and reused materials. 
      “I am pleased that NASA’s LunaRecycle Challenge will contribute to solutions pertaining to technological needs within advanced manufacturing and habitats,” said Kim Krome, acting program manager for agency’s Centennial Challenges, and challenge manager of LunaRecycle. “We are very excited to see what solutions our global competitors generate, and we are eager for this challenge to serve as a positive catalyst for bringing the agency, and humanity, closer to exploring worlds beyond our own.” 
      NASA has contracted The University of Alabama to be the allied partner for the duration of the challenge. The university, based in Tuscaloosa, Alabama, will coordinate with former Centennial Challenge winner AI Spacefactory to facilitate the challenge and manage its competitors.  
      To register as a participant in NASA’s LunaRecycle Challenge, visit: lunarecyclechallenge.ua.edu. 
      NASA’s LunaRecycle Challenge is led by the agency’s Kennedy Space Center with support from Marshall Space Flight Center. The competition is a NASA’s Centennial Challenge, based at Marshall. Centennial Challenges are part of NASA’s Prizes, Challenges, and Crowdsourcing program within the agency’s Space Technology Mission Directorate.

      Fueling Complete on Europa Clipper Spacecraft
      Technicians completed loading propellants in the agency’s Europa Clipper spacecraft Sept. 22, inside the Payload Hazardous Servicing Facility at NASA’s Kennedy Space Center.
      Technicians work to complete operations prior to propellant load for NASA’s Europa Clipper spacecraft inside the Payload Hazardous Servicing Facility at the agency’s Kennedy Space Center on Sept. 11.NASA/Kim Shiflett Housed in the largest spacecraft NASA has ever built for a planetary mission, Europa Clipper’s propulsion module is an aluminum cylinder 10 feet long and 5 feet wide, and it holds the spacecraft’s array of 24 engines and 6067.6 pounds of propellant in two propulsion tanks, as well as the spacecraft’s helium pressurant tanks. The fuel and oxidizer held by the tanks will flow to the 24 engines, creating a controlled chemical reaction to produce thrust in space during its journey to determine whether there are places below the surface of Jupiter’s icy moon, Europa, that could support life.
      After launch, the spacecraft plans to fly by Mars in February 2025, then back by Earth in December 2026, using the gravity of each planet to increase its momentum. With help of these “gravity assists,” Europa Clipper will achieve the velocity needed to reach Jupiter in April 2030.
      NASA is targeting launch Oct. 10 aboard a Space X Falcon Heavy rocket from NASA Kennedy’s historic Launch Complex 39A.
      Managed by Caltech in Pasadena, California, NASA’s Jet Propulsion Laboratory leads the development of the Europa Clipper mission in partnership with the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, for NASA’s Science Mission Directorate. The main spacecraft body was designed by APL in collaboration with NASA JPL and NASA’s Goddard Space Flight Center. The Planetary Missions Program Office at NASA’s Marshall Space Flight Center executes program management of the Europa Clipper mission. NASA’s Launch Services Program, based at Kennedy, manages the launch service for the Europa Clipper spacecraft.
