Preparations for Next Moonwalk Simulations Underway (and Underwater)
From left, NASA astronauts, Tracy C. Dyson, Mike Barratt, Matthew Dominick, and Jeanette Epps, who served as part of Expedition 71, will discuss their recent missions to the International Space Station during a visit to Marshall Space Flight Center on Jan. 29. NASA 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

4 Min Read NASA Space Tech’s Favorite Place to Travel in 2025: The Moon!
The first image from space of Firefly's Blue Ghost mission 1 lunar lander as it begins its 45-day transit period to the Moon. Credits: Firefly Aerospace NASA Space Technology has big travel plans for 2025, starting with a trip to the near side of the Moon!
Among ten groundbreaking NASA science and technology demonstrations, two technologies are on a ride to survey lunar regolith – also known as “Moon dust” – to better understand surface interactions with incoming lander spacecraft and payloads conducting experiments on the surface. These dust demonstrations and the data they’re designed to collect will help support future lunar missions.
Blue Ghost Mission 1 launched at 1:11 a.m. EST aboard a SpaceX Falcon 9 rocket from Launch Complex 39A at the agency’s Kennedy Space Center in Florida. The company is targeting a lunar landing on Sunday, March 2.

NASA’s Electrodynamic Dust Shield (EDS) will lift, transport, and remove particles using electric fields to repel and prevent hazardous lunar dust accumulation on surfaces. The agency’s Stereo Camera for Lunar Plume-Surface Studies (SCALPSS) technology will use stereo imaging to capture the impact of rocket plumes on lunar regolith as the lander descends to the Moon’s surface, returning high-resolution images that will help in creating models to predict regolith erosion – an important task as bigger, heavier payloads are delivered to the Moon in close proximity to each other.
The EDS and SCALPSS technologies will be delivered to the Moon on Firefly’s first Blue Ghost mission, named Ghost Riders in the Sky, as part of NASA’s CLPS (Commercial Lunar Payload Services) initiative. Its landing target is a 300-mile-wide basin located on the Moon’s near side, called Mare Crisium – a large, dark, basaltic plain that filled an ancient asteroid impact. First-of-their-kind experiments will deploy after landing to gather important data in a broad spectrum of areas including geophysical characteristics, global navigation, radiation tolerant computing, and the behavior of lunar regolith.
Replicating the Moon’s harsh environment on Earth is a significant challenge because of extreme temperatures, low gravity, radiation, and dusty surface. The CLPS initiative provides unprecedented access to the lunar surface, allowing us to demonstrate technologies in the exact conditions they were designed for. Missions like Blue Ghost Mission 1 are a true game changer for NASA technology advancement and demonstration.”

The Moon’s dusty environment was one of the greatest challenges astronauts faced during Apollo Moon missions, posing hazards to lunar surface systems, space suits, habitats, and instrumentation. What was learned from those early missions – and from thousands of experiments conducted on Earth and in space since – is that successful surface missions require the ability to eliminate dust from all kinds of systems. Lunar landings, for example, cause lunar dust to disperse in all directions and collect on everything that lands there with it. This is one of the reasons such technologies are important to understand. The SCALPSS technology will study the dispersion of lunar dust, while EDS will demonstrate a solution to mitigate it.
Getting this new data on lunar regolith with be pivotal for our understanding of the lunar surface. We’ve long known that lunar dust is a huge challenge. The Lunar Surface Innovation Initiative has enabled us to initiate lunar dust mitigation efforts across the agency, working with industry and international partners. The lunar science, exploration, and technology communities are eager to have new quantitative data, and to prove laboratory experiments and develop technology solutions.”

[VIDEO] Dust on the lunar surface is a significant hazard for systems and astronauts living and working on the Moon. NASA space technologies are developing solutions to retire hurdles in this capability area. NASA Space Technology Dust mitigation technology has come a long way, but we still have a lot to learn to develop surface systems and infrastructure for more complex missions. LSII is actively engaged in this effort, working with the lunar community across sectors to expand knowledge and design new approaches for future technologies. Working alongside the Lunar Surface Innovation Consortium, LSII has a unique opportunity to take a holistic look at dust’s role in the development of surface infrastructure with other key capability areas including in-situ resource utilization, surface power, and surviving the lunar night.
Learning from the the Moon benefits Mars science and exploration
Capabilities for minimizing dust interaction are as important for future missions on Mars as it is for missions on the Moon. Like the Moon, Mars is also covered with regolith, also called Martian dust or Martian soil, but the properties are different than lunar regolith, both in shape and mineralogy. The challenges Mars rovers have encountered with Martian regolith have provided great insight into the challenges we will face during lunar surface missions. Learning is interwoven and beneficial to future missions whether hundreds of thousands of miles from Earth, on the Moon, or millions, on Mars.

On Jan. 24, 1985, space shuttle Discovery took off from NASA’s Kennedy Space Center (KSC) in Florida on STS-51C, the first space shuttle mission entirely dedicated to the Department of Defense (DOD). As such, many of the details of the flight remain classified. Discovery’s crew of Commander Thomas “T.K.” Mattingly, Pilot Loren Shriver, Mission Specialists Ellison Onizuka and James Buchli, and Payload Specialist Gary Payton deployed a classified satellite that used an Inertial Upper Stage (IUS) to reach its final geostationary orbit. The three-day mission ended with a landing at KSC. Postflight inspection of the Solid Rocket Boosters (SRBs) revealed the most significant erosion of O-ring seals seen in the shuttle program up to that time, attributed to unusually cold weather before and during launch.
The STS-51C crew of Pilot Loren Shriver, seated left, and Commander Thomas “T.K.” Mattingly; Payload Specialist Gary Payton, standing left, and Mission Specialists James Buchli and Ellison Onizuka. The STS-51C crew patch. In October 1982, NASA assigned astronauts Mattingly, Shriver, Onizuka, and Buchli as the STS-10 crew for a dedicated DOD flight aboard Challenger then scheduled for September 1983. Payton joined the crew as a payload specialist in the summer of 1983 with Keith Wright assigned as his backup. The failure of the IUS on STS-6 in April 1983 delayed the STS-10 mission, that also used the IUS, until engineers could identify and fix the cause of the problem. By September 1983, NASA had remanifested the crew and the payload on STS-41F with a July 1984 launch, that changed to STS-41E by November 1983. Additional delays in fixing the IUS delayed the mission yet again, by June 1984 redesignated as STS-51C and slated for December 1984 aboard Challenger.
STS-51C marked the third spaceflight for Mattingly, selected in 1966 as part of NASA’s fifth group of astronauts. He served on the prime crew for Apollo 13 until exposure to German measles forced his last-minute replacement by his backup. He then flew on Apollo 16 and STS-4. For Shriver, Onizuka, and Buchli, all three selected as astronauts in the class of 1978, STS-51C marked their first trip into space. The U.S. Air Force selected Payton and Wright in August 1979 in its first class of Manned Spaceflight Engineers, and STS-51C marked Payton’s first and only space mission.
In November 1984, NASA decided to delay STS-51C from December 1984 to January 1985 and swap orbiters from Challenger to Discovery. Postflight inspections following Challenger’s STS-41G mission in October 1984 revealed degradation of the bonding materials holding thermal protection system tiles onto the orbiter, requiring the replacement of 4,000 tiles. The time required to complete the work precluded a December launch. Tests conducted on Discovery prior to its November STS-51A mission revealed the bonding material to be sound.
Space shuttle Discovery rolls out to Launch Pad 39A. The STS-51C crew poses during launch pad evacuation drills associated with the Terminal Countdown Demonstration Test. The STS-51C crew exits crew quarters for the ride to Launch Pad 39A. On Jan. 5, 1985, Discovery rolled out from KSC’s Vehicle Assembly Building, where workers mated it with its External Tank (ET) and SRBs, to Launch Pad 39A. There, engineers conducted the Terminal Countdown Demonstration Test, essentially a dress rehearsal for the actual countdown, on Jan. 6-7, with the crew participating in the final few hours much as they would on launch day. The astronauts returned to KSC on Jan. 20 to prepare for the planned launch on Jan. 23. The day before, NASA managers decided to delay the launch by one day due to unseasonably cold weather, with concern about sub-freezing temperatures causing ice to form on the ET and possibly coming loose during ascent and damaging the vehicle. The DOD had requested that NASA keep the actual launch time secret until T minus nine minutes, with most of the countdown taking place hidden from public view.
Liftoff of space shuttle Discovery on STS-51C. Liftoff of Discovery on its third mission, STS-51C, came at 2:50 p.m. EST on Jan. 24, beginning the 15th space shuttle flight. Eight and a half minutes later, Discovery and its five-man crew had reached orbit. And, at the DOD customer’s request, all public coverage of the mission ended. Although NASA could not reveal the spacecraft’s orbital parameters, trade publications calculated that Discovery first entered an elliptical orbit, circularized over the next few revolutions, prior to Onizuka deploying the IUS and payload combination on the seventh orbit. Neither NASA nor the DOD have released any imagery of the deployment or even of the payload bay, with only a limited number of in-cabin and Earth observation photographs made public.

Sunlight streams through Earth’s upper atmosphere, with Discovery’s tail and Orbital Maneuvering Engine pods outlined by sunlight. The Pacific coast of Guatemala and southern Mexico. New Orleans and the Mississippi River delta. Discovery touches down at NASA’s Kennedy Space Center in Florida. The STS-51C astronauts are greeted by NASA officials as they exit Discovery. To maintain the mission’s secrecy, NASA could reveal the touchdown time only 16 hours prior to the event. On Jan. 27, Mattingly and Shriver brought Discovery to a smooth landing at KSC’s Shuttle Landing Facility after a flight of three days one hour 33 minutes, the shortest space shuttle mission except for the first two orbital test flights. The astronauts orbited the Earth 49 times. About an hour after touchdown, the astronaut crew exited Discovery and boarded the Astrovan for the ride back to crew quarters. Neither NASA management nor the astronauts held a post mission press conference. The U.S. Air Force announced only that the “IUS aboard STS-51C was deployed from the shuttle Discovery and successfully met its mission objectives.” Later in the day, ground crews towed Discovery to the Orbiter Processing Facility to begin preparing it for its next planned mission, STS-51D in March.
Postscript
Following the recovery of SRBs after each shuttle mission, engineers conducted detailed inspections before clearing them for reuse. After STS-51C, inspections of the critical O-ring seals that prevented hot gases from escaping from the SRB field joints revealed significant erosion and “blow-by” between the primary and secondary O-rings. Both left and right hand SRBs showed this erosion, the most significant of the program up to that time. Importantly, these O-rings experienced weather colder than any previous shuttle mission, with overnight ambient temperatures in the teens and twenties. Even at launch time, the O-rings had reached only 60 degrees. Engineers believed that these cold temperatures made the O-rings brittle and more susceptible to erosion. One year later, space shuttle Challenger launched after similarly cold overnight temperatures, with O-rings at 57 degrees at launch time. The Rogers Commission report laid the blame of the STS-51L accident on the failure of O-rings that allowed super-hot gases to escape from the SRB and impinge on the hydrogen tank in the ET, resulting in the explosion that destroyed the orbiter and claimed the lives of seven astronauts. The commission also faulted NASA’s safety culture for not adequately addressing the issue of O-ring erosion, a phenomenon first observed on STS-2 and to varying degrees on several subsequent missions.
