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/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.”

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.”

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.

NASA’s SpaceX Crew-9 Aboard International Space Station NASA astronaut Nick Hague and Roscosmos cosmonaut Aleksandr Gorbunov arrived at the International Space Station on Sept. 29 as the SpaceX Dragon Freedom docked to the orbiting complex at 4:30 p.m. CDT, joining Expedition 72 for a five-month science research mission aboard the orbiting laboratory.
NASA’s SpaceX Crew-9 crew joins Expedition 72 aboard the International Space Station.NASA The two crew members of NASA’s SpaceX Crew-9 mission launched at 12:17 p.m. CDT Sept. 28 for a science expedition aboard the International Space Station. This is the first human spaceflight mission launched from Space Launch Complex-40 at Cape Canaveral Space Force Station, and the agency’s ninth commercial crew rotation mission to the space station.
The duo joined the space station’s Expedition 72 crew of NASA astronauts Michael Barratt, Matthew Dominick, Jeanette Epps, Don Pettit, Butch Wilmore, and Suni Williams, as well as Roscosmos cosmonauts Alexander Grebenkin, Alexey Ovchinin, and Ivan Vagner. The number of crew aboard the space station increased to 11 for a short time until Crew-8 members Barratt, Dominick, Epps, and Grebenkin depart the space station early this month.
The crewmates will conduct more than 200 scientific investigations, including blood clotting studies, moisture effects on plants grown in space, and vision changes in astronauts during their mission. Following their stay aboard the space station, Hague and Gorbunov will be joined by Williams and Wilmore to return to Earth in February 2025.
With this mission, NASA continues to maximize the use of the orbiting laboratory, where people have lived and worked continuously for more than 23 years, testing technologies, performing science, and developing the skills needed to operate future commercial destinations in low Earth orbit and explore farther from Earth. Research conducted at the space station benefits people on Earth and paves the way for future long-duration missions to the Moon under NASA’s Artemis campaign, and beyond.

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.

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.
