NASA will host four astronauts at 9 a.m. CDT Wednesday, Jan. 29, for a media opportunity at the agency’s Marshall Space Flight Center in Huntsville, Alabama.

NASA astronauts Matt Dominick, Mike Barratt, Jeanette Epps, and Tracy C. Dyson served as part of Expedition 71 and will discuss their recent missions to the International Space Station.

Dominick, Barratt, and Epps launched aboard NASA’s SpaceX Crew-8 mission in March 2024 and returned to Earth in October 2024 after spending nearly eight months aboard the orbiting complex. Dyson launched aboard a Roscosmos Soyuz spacecraft also in March 2024 and returned in September 2024 after completing a six-month research mission aboard the space station.

Media are invited to attend the event and visit with the astronauts as they discuss their science missions aboard the microgravity laboratory and other mission highlights. Media interested in participating must confirm their attendance by 12 p.m., Monday, Jan. 27, to both Lance D. Davis – lance.d.davis@nasa.gov – and Joel Wallace – joel.w.wallace@nasa.gov –  in Marshall’s Office of Communications. 

Media must arrive by 8 a.m., Wednesday, to the Redstone Arsenal Joint Visitor Control Center Gate 9 parking lot, located at the Interstate 565 interchange on Research Park Boulevard. The event will take place in the NASA Marshall Activities Building 4316. Vehicles are subject to a security search at the gate, so please allow extra time. All members of the media and drivers will need photo identification. Drivers will need proof of insurance if requested.

The Expedition 71 crew conducted hundreds of technology demonstrations and science experiments, including the bioprinting of human tissues. These higher-quality tissues printed in microgravity could help advance the production of organs and tissues for transplant and improve 3D printing of foods and medicines on future long-duration space missions. The crew also looked at  neurological organoids, created with stem cells from patients to study neuroinflammation, a common feature of neurodegenerative conditions such as Parkinson’s disease. The organoids provided a platform to study these diseases and their treatments and could help address how extended spaceflight affects the brain.

As part of Crew-8, Dominick served as commander, Barratt served as pilot, and Epps served as a mission specialist. Dyson launched aboard a Soyuz space as part of an international crew and served as a flight engineer on a six-month research mission. The expedition to the space station was the first spaceflight for Dominick, third for Barratt, first for Epps, and third for Dyson.

The International Space Station is a convergence of science, technology, and human innovation that enables research not possible on Earth. For more than 24 years, NASA has supported a continuous human presence aboard the orbiting laboratory, through which astronauts have learned to live and work in space for extended periods of time. The space station is a springboard for developing a low Earth economy and NASA’s next great leaps in exploration, including missions to the Moon under Artemis and, ultimately, human

Onboard computers are critical to space exploration, aiding nearly every spacecraft function from propulsion and navigation systems to life support technology, science data retrieval and analysis, communications, and reentry.

But computers in space are susceptible to ionizing solar and cosmic radiation. Just one high-energy particle can trigger a so-called “single event effect,” causing minor data errors that lead to cascading malfunctions, system crashes, and permanent damage. NASA has long sought cost-effective solutions to mitigate radiation effects on computers to ensure mission safety and success.

Enter the Radiation Tolerant Computer (RadPC) technology demonstration, one of 10 NASA payloads set to fly aboard the next lunar delivery for the agency’s CLPS (Commercial Lunar Payload Services) initiative. RadPC will be carried to the Moon’s surface by Firefly Aerospace’s Blue Ghost 1 lunar lander.

Developed by researchers at Montana State University in Bozeman, RadPC aims to demonstrate computer recovery from faults caused by single event effects of ionizing radiation. The computer is designed to gauge its own real-time state of health by employing redundant processors implemented on off-the-shelf integrated circuits called field programmable gate arrays. These tile-like logic blocks are capable of being easily replaced following a confirmed ionizing particle strike. In the event of a radiation strike, RadPC’s patented recovery procedures can identify the location of the fault and repair the issue in the background.

As an added science benefit, RadPC carries three dosimeters to measure varying levels of radiation in the lunar environment with each tuned to different sensitivity levels. These dosimeters will continuously measure the interaction between Earth’s magnetosphere and the solar wind during its journey to the Moon. It will also provide detailed radiation information about Blue Ghost’s lunar landing site at Mare Crisium, which could help to safeguard future Artemis astronauts.

“This is RadPC’s first mission out into the wild, so to speak,” said Dennis Harris, who manages the payload for the CLPS initiative at NASA’s Marshall Space Flight Center in Huntsville, Alabama. “The RadPC CLPS payload is an exciting opportunity to verify a radiation-tolerant computer option that could make future Moon to Mars missions safer and more cost-effective.”

Under the CLPS model, NASA is investing in commercial delivery services to the Moon to enable industry growth and support long-term lunar exploration. As a primary customer for CLPS deliveries, NASA aims to be one of many customers on future flights. Marshall manages the development of seven of the 10 CLPS payloads carried on Firefly’s Blue Ghost lunar lander.

Among all the challenges of voyaging to and successfully landing on other worlds, the effective collection and study of soil and rock samples cannot be underestimated.

To quickly and thoroughly collect and analyze samples during next-generation Artemis Moon missions and future journeys to Mars and other planetary bodies, NASA seeks a paradigm shift in techniques that will more cost-effectively obtain samples, conduct in situ testing with or without astronaut oversight, and permit real-time sample data return to researchers on Earth.

That’s the planned task of an innovative technology demonstration called Lunar PlanetVac (LPV), one of 10 NASA payloads flying aboard the next lunar delivery for the agency’s CLPS (Commercial Lunar Payload Services) initiative. LPV will be carried to the surface by Firefly Aerospace’s Blue Ghost 1 lunar lander.

Developed by Honeybee Robotics, a Blue Origin company of Altadena, California, LPV is a pneumatic, compressed gas-powered sample acquisition and delivery system – essentially, a vacuum cleaner that brings its own gas. It’s designed to efficiently collect and transfer lunar soil from the surface to other science instruments or sample return containers without reliance on gravity. Secured to the Blue Ghost lunar lander, LPV’s sampling head will use pressurized gas to stir up the lunar regolith, or soil, creating a small tornado. If successful, material from the dust cloud it creates then will be funneled into a transfer tube via the payload’s secondary pneumatic jets and collected in a sample container. The entire autonomous operation is expected to take just seconds and maintains planetary protection protocols. Collected regolith – including particles up to 1 cm in size, or roughly 0.4 inches – will be sieved and photographed inside the sample container with the findings transmitted back to Earth in real time.

The innovative approach to sample collection and in situ testing could prove to be a game-changer, said Dennis Harris, who manages the LPV payload for the CLPS initiative at NASA’s Marshall Space Flight Center in Huntsville, Alabama.

“There’s no digging, no mechanical arm to wear out requiring servicing or replacement – it functions like a vacuum cleaner,” Harris said. “The technology on this CLPS payload could benefit the search for water, helium, and other resources and provide a clearer picture of in situ materials available to NASA and its partners for fabricating lunar habitats and launch pads, expanding scientific knowledge and the practical exploration of the solar system every step of the way.”

Apollo astronauts set up mirror arrays, or “retroreflectors,” on the Moon to accurately reflect laser light beamed at them from Earth with minimal scattering or diffusion. Retroreflectors are mirrors that reflect the incoming light back in the same incoming direction. Calculating the time required for the beams to bounce back allowed scientists to precisely measure the Moon’s shape and distance from Earth, both of which are directly affected by Earth’s gravitational pull. More than 50 years later, on the cusp of NASA’s crewed Artemis missions to the Moon, lunar research still leverages data from those Apollo-era retroreflectors.

As NASA prepares for the science and discoveries of the agency’s Artemis campaign, state-of-the-art retroreflector technology is expected to significantly expand our knowledge about Earth’s sole natural satellite, its geological processes, the properties of the lunar crust and the structure of lunar interior, and how the Earth-Moon system is changing over time. This technology will also allow high-precision tests of Einstein’s theory of gravity, or general relativity.

That’s the anticipated objective of an innovative science instrument called NGLR (Next Generation Lunar Retroreflector), one of 10 NASA payloads set to fly aboard the next lunar delivery for the agency’s CLPS (Commercial Lunar Payload Services) initiative. NGLR-1 will be carried to the surface by Firefly Aerospace’s Blue Ghost 1 lunar lander.

Developed by researchers at the University of Maryland in College Park, NGLR-1 will be delivered to the lunar surface, located on the Blue Ghost lander, to reflect very short laser pulses from Earth-based lunar laser ranging observatories, which could greatly improve on Apollo-era results with sub-millimeter-precision range measurements. If successful, its findings will expand humanity’s understanding of the Moon’s inner structure and support new investigations of astrophysics, cosmology, and lunar physics – including shifts in the Moon’s liquid core as it orbits Earth, which may cause seismic activity on the lunar surface.

“NASA has more than half a century of experience with retroreflectors, but NGLR-1 promises to deliver findings an order of magnitude more accurate than Apollo-era reflectors,” said Dennis Harris, who manages the NGLR payload for the CLPS initiative at NASA’s Marshall Space Flight Center in Huntsville, Alabama.

Deployment of the NGLR payload is just the first step, Harris noted. A second NGLR retroreflector, called the Artemis Lunar Laser Retroreflector (ALLR), is currently a candidate payload for flight on NASA’s Artemis III mission to the Moon and could be set up near the lunar south pole. A third is expected to be manifested on a future CLPS delivery to a non-polar location.

“Once all three retroreflectors are operating, they are expected to deliver unprecedented opportunities to learn more about the Moon and its relationship with Earth,” Harris said.

Under the CLPS model, NASA is investing in commercial delivery services to the Moon to enable industry growth and support long-term lunar exploration. As a primary customer for CLPS deliveries, NASA aims to be one of many customers on future flights.
