Preparations for Next Moonwalk Simulations Underway (and Underwater)
NASA/Lori Losey What do the X-15 and the space shuttles have in common? Information from the rocket plane and the spacecraft, as well as many experimental aircraft, were tracked from a pedestal and telemetry dish during key eras in flight history at or near NASA’s Armstrong Flight Research Center in Edwards, California.
When the NASA facility’s administration Building 4800 was built in the 1950s, the infrastructure was included to anchor the rooftop pedestal and dish as the primary way to gather data from aircraft during flights. It was retired in 2015, but a recent roofing project enabled relocation of the artifact to a new place of honor for its support of many experimental aircraft such as the lifting body aircraft, the reverse swept wing X-29, and the highly maneuverable X-31.
“Gathering telemetry data from aircraft on missions is at the core of what we do. Close proximity to the back ramp was one of the big advantages of having the telemetry antenna on the roof in the early days,” said Bob Guere, NASA Armstrong Range Operations chief, referring to the area where aircraft taxi from the hangar to the flightline. “You were able to support ground tests and check airplanes before they taxied without having to use telemetry antennas positioned further away.”
A cable is secured on a rooftop pedestal located on Building 4800 at NASA’s Armstrong Flight Research Center in Edwards, California, on Oct. 4, 2024. The pedestal, which was prepared for a helicopter lift to remove it from the roof, was used since the 1950s until 2015 to enable different telemetry dishes to collect data from research aircraft.NASA/Carla Thomas The rooftop pedestal was key in the early days of the center and its refurbishment in 2003 restored its value. The transformation also included certification to meet Space Shuttle Program landing requirements.
“When a space shuttle deorbited from space it was coming over the top of Edwards,” Guere said. “Telemetry antennas on the hill near NASA Armstrong looked down and with dirt and concrete in the background there were reflections. The rooftop antenna was closer to ground level and looked up as the orbiter was coming in for a landing. It provided an excellent link for shuttle landings.”
The pedestal and dish were not removed when it was decommissioned because of the cost. Now, it’s economical to use a helicopter to remove the pedestal from the roof compared to other options as part of a major project focusing primarily on re-roofing Building 4800. The helicopter lift of the pedestal took a month to plan, plus time to obtain airspace operation and landing permits from the Air Force for the removal project, said Bryan Watters, NASA Armstrong roof project manager.

The pedestal was used since the 1950s to 2015 to house different telemetry dishes to collect data from research aircraft.NASA/Carla Thomas The pedestal and riser measured 16 feet tall above the rooftop and housed an assembly for the 12-foot dish to rotate. The pedestal and dish together weight about 2,500 pounds and were removed separately. Crews checked the eight bolts anchoring the pedestal and dish to infrastructure on the roof prior to the arrival of a helicopter Oct. 3 before the helicopter arrived.
The following day, after additional briefings, the helicopter was positioned over Building 4800 and a cable was lowered and attached to the pedestal. Once secured, the helicopter slowly gained altitude and took its passenger to the south side of the building. There it was released from the cable and taken to a nearby warehouse for storage. Roofers demolished the steel platform on which the pedestal was located to prepare the area for new roofing materials.
Officials have not determined where the pedestal will be displayed. There are several options to place the pedestal and dish by the famous retired research aircraft on display near the entrance of NASA Armstrong.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
The Radiation Tolerant Computer, or RadPC, payload undergoes final checkout at Montana State University in Bozeman, which leads the payload project. RadPC is one of 10 NASA payloads set to fly aboard the next delivery for NASA’s CLPS (Commercial Lunar Payload Services) initiative in 2025. RadPC prototypes previously were tested aboard the International Space Station and Earth-orbiting satellites, but the technology demonstrator will undergo its biggest trial in transit to the Moon – passing through the Earth’s Van Allen radiation belts – and during its roughly two-week mission on the lunar surface. Photo courtesy Firefly Aerospace 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.

Inside of the Electrostatics and Surface Physics Laboratory at NASA’s Kennedy Space Center in Florida, an electrodynamic dust shield (EDS) is in view on Jan. 18, 2023. The dust shield is one of the payloads that will fly aboard Firefly Aerospace’s Blue Ghost lunar lander as part of NASA’s Commercial Lunar Payload Services (CLPS) initiative. NASA/Cory Huston Defeating dust may be a small concern for most people on Earth, but for astronauts and spacecraft destined for the Moon or Mars, it is a significant hazard that must be mitigated. That’s why researchers at NASA’s Kennedy Space Center in Florida are seeking innovative ways to use the Electrodynamic Dust Shield (EDS) technology.
The EDS technology is headed to the Moon as part of the agency’s Artemis campaign. This innovative technology will be demonstrated on the lunar surface, where it will use electrical forces to lift and remove lunar regolith, or dirt, from various surfaces.
This dust-mitigating technology is one of 10 payloads aboard the next lunar delivery through NASA’s CLPS (Commercial Lunar Payload Services) initiative, set to launch from the agency’s Kennedy Space Center in Florida Wednesday, Jan. 15, with Firefly Aerospace’s Blue Ghost Lander.
Using transparent electrodes and electric fields, EDS technology can lift and remove dust from a variety of surfaces for space applications ranging from thermal radiators, solar panels, and camera lenses to spacesuits, boots, and helmet visors. Controlling and removing the charged dust will be critical to the success of Moon missions under the agency’s CLPS initiative and Artemis campaign.
“For these CLPS and Artemis missions, dust exposure is a concern because the lunar surface is far different than what we’re used to here,” said Dr. Charles Buhler, lead research scientist at the Electrostatics and Surface Physics Laboratory at Kennedy. “Lunar regolith dust can get into gaskets and seals, into hatches, and even into habitats, which can pose a lot of issues for spacecraft and astronauts.”
Unlike dust particles on Earth, dust on the Moon’s surface is sharp and abrasive – like tiny shards of glass – because it hasn’t been exposed to weathering and elements like water and oxygen.
“Simply brushing lunar regolith across surfaces can make the problem worse because it’s also very electrostatically charged and highly insulating,” Buhler 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. EDS was funded by the Space Technology Mission Directorate (STMD) Game Changing Development Program (GCD).

Technicians have successfully integrated NASA’s Nancy Grace Roman Space Telescope’s payload – the telescope, instrument carrier, and two instruments – to the spacecraft that will deliver the observatory to its place in space and enable it to function while there.
“With this incredible milestone, Roman remains on track for launch, and we’re a big step closer to unveiling the cosmos as never before,” said Mark Clampin, acting deputy associate administrator for the Science Mission Directorate at NASA Headquarters in Washington. “It’s been fantastic to watch the team’s progress throughout the integration phase. I look forward to Roman’s transformative observations.”
Technicians recently integrated the payload – telescope, instrument carrier, and two instruments – for NASA’s Nancy Grace Roman Space Telescope in the big clean room at the agency’s Goddard Space Flight Center in Greenbelt, Md. NASA/Chris Gunn The newly joined space hardware will now undergo extensive testing. The first test will ensure each major element operates as designed when integrated with the rest of the observatory and establish the hardware’s combined performance. Then environmental tests will subject the payload to the electromagnetic, vibration, and thermal vacuum environments it will experience during launch and on-orbit operations. These tests will ensure the hardware and the launch vehicle will not interfere with each other when operating, verify the communications antennas won’t create electromagnetic interference with other observatory hardware, shake the assembly to make sure it will survive extreme vibration during launch, assess its performance across its expected range of operating temperatures, and make sure the instruments and mirrors are properly optically aligned.
Meanwhile, Roman’s deployable aperture cover will be integrated with the outer barrel assembly, and then the solar panels will be added before spring. Then the structure will be joined to the payload and spacecraft this fall.
The Roman mission remains on track for completion by fall 2026 and launch no later than May 2027.

City lights streak across Earth and an aurora is visible on the horizon as the International Space Station passes over Lake Michigan.NASA For more than 24 years, NASA has supported a continuous U.S. human presence aboard the International Space Station, advancing scientific knowledge and making research breakthroughs not possible on Earth for the benefit of humanity. The space station is a springboard to NASA’s next great leaps in exploration, including future missions to the Moon under Artemis, and ultimately, human exploration of Mars.
Read more about the groundbreaking work conducted in 2024 aboard the station:
Robot performs remote simulated surgery
On long-duration missions, crew members may need surgical procedures, whether simple stitches or an emergency appendectomy. A small robot successfully performed simulated surgical procedures on the space station in early February 2024 for the Robotic Surgery Tech Demo, using two “hands” to grasp and cut rubber bands simulating tissue. Researchers compare the procedures conducted aboard the station and on Earth to evaluate the effects of microgravity and communication delays between space and ground.

On May 30,2024, the ESA (European Space Agency) Metal 3D Printer investigation created a small stainless steel s-curve, the first metal 3D print in space. Crew members on future missions could print metal parts for equipment maintenance, eliminating the need to pack spare parts and tools at launch. This technology also has the potential to improve additive manufacturing on Earth.

The space station orbits roughly 250 miles above and passes over 90 percent of Earth’s population, providing a unique perspective for photographing the planet. Astronauts have taken more than 5.3 million images of Earth to monitor the planet’s changing landscape. The Expedition 71 crew took over 630,000 images, well above the average of roughly 105,000 for a single mission. This year, images included the April solar eclipse and auroras produced as the Sun’s 11-year activity cycle peaks. Others supported response to over 14 disaster events including hurricanes. In addition, 80,000 images were geolocated using machine learning, improving public search capabilities.

From mid-February to mid-March of 2024, the Flawless Space Fibers-1 system produced more than seven miles of optical fiber in space. One draw of more than a half mile of fiber surpassed the prior record of 82 feet for the longest fiber manufactured in space, demonstrating that commercial lengths of fiber can be produced in orbit. Fibers produced in microgravity can be superior to those produced in Earth’s gravity. These fibers are made from ZBLAN, a glass alloy with the potential to provide more than 10 times the transmission capacity of traditional silica-based fibers.

In May 2024, BFF-Cardiac successfully bioprinted a three-dimensional human heart tissue sample using the Redwire BioFabrication Facility. Tissues bioprinted in the microgravity of the space station hold their shape without the use of artificial scaffolds. These bioprinted human heart tissues eventually could be used to create personalized patches for tissue damaged by events such as heart attacks. The tissue sample is undergoing further testing on Earth.

The Orion spacecraft carried 5,600 passive and 34 active radiation detectors on its Artemis I uncrewed mission around the Moon in November 2022. Some of these devices previously were tested on the space station: HERA (Hybrid Electronic Radiation Assessor), which detects radiation events such as solar flares; the ESA (European Space Agency) Active Dosimeters, a wearable device collecting real-time data on individual radiation doses; and the AstroRad Vest, a garment to protect radiation-sensitive organs and tissues. In 2024, researchers released evaluation of data collected in 2022 by these tools that indicate the Orion spacecraft can protect astronauts on lunar missions from potentially hazardous radiation. The orbiting laboratory remains a valuable platform for testing technology for missions beyond Earth’s orbit.
