Preparations for Next Moonwalk Simulations Underway (and Underwater)
Regolith Adherence Characterization, or RAC, is one of 10 science and technology instruments flying on NASA’s next Commercial Lunar Payload Services (CLPS) flight as part of the Blue Ghost Misison-1. Developed by Aegis Aerospace of Webster, Texas, RAC is designed to study how lunar dust reacts to more than a dozen different types of material samples, located on the payload’s wheels. Photo courtesy Firefly Aerospace The Moon may look like barren rock, but it’s actually covered in a layer of gravel, pebbles, and dust collectively known as “lunar regolith.” During the Apollo Moon missions, astronauts learned firsthand that the fine, powdery dust – electromagnetically charged due to constant bombardment by solar and cosmic particles – is extremely abrasive and clings to everything: gloves, boots, vehicles, and mechanical equipment. What challenges does that dust pose to future Artemis-era missions to establish long-term outposts on the lunar surface?
That’s the task of an innovative science instrument called RAC-1 (Regolith Adherence Characterization), one of 10 NASA payloads flying aboard the next delivery for the agency’s CLPS (Commercial Lunar Payload Services) initiative and set to be carried to the surface by Firefly Aerospace’s Blue Ghost 1 lunar lander.
Developed by Aegis Aerospace of Webster, Texas, RAC will expose 15 sample materials – fabrics, paint coatings, optical systems, sensors, solar cells, and more – to the lunar environment to determine how tenaciously the lunar dust sticks to each one. The instrument will measure accumulation rates during landing and subsequent routine lander operations, aiding identification of those materials which best repel or shed dust. The data will help NASA and its industry partners more effectively test, upgrade, and protect spacecraft, spacesuits, habitats, and equipment in preparation for continued exploration of the Moon under the Artemis campaign.
“Lunar regolith is a sticky challenge for long-duration expeditions to the surface,” said Dennis Harris, who manages the RAC payload for NASA’s CLPS initiative at the agency’s Marshall Space Flight Center in Huntsville, Alabama. “Dust gets into gears, sticks to spacesuits, and can block optical properties. RAC will help determine the best materials and fabrics with which to build, delivering more robust, durable hardware, products, and equipment.”
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. NASA’s Marshall Space Flight Center in Huntsville, Alabama, manages the development of seven of the 10 CLPS payloads carried on Firefly’s Blue Ghost lunar lander.

Thales Alenia Space A maze of cables and sensors snakes through a major piece of Gateway, humanity’s first space station around the Moon, during a key testing phase earlier this year to ensure the lunar-orbiting science lab can withstand the harsh conditions of deep space.
HALO (Habitation and Logistics Outpost) is one of four Gateway modules where international teams of astronauts will live, conduct science, and prepare for missions to the lunar South Pole region. Other elements will be provided by the European Space Agency, Japanese Aerospace Exploration Agency, and the Mohammed Bin Rashid Space Centre of the United Arab Emirates. The Canadian Space Agency is providing Gateway’s Canadarm3 advanced robotics system.
HALO is provided by Northrop Grumman and their subcontractor, Thales Alenia Space. The module completed testing in Turin, Italy, before its expected arrival to the United States in 2025. Northrop Grumman will complete final outfitting of HALO and integrate it with Gateway’s Power and Propulsion Element for launch ahead of the Artemis IV mission on a SpaceX Falcon Heavy rocket.

Official portrait of Carlos Garcia-Galan, deputy manager for the Gateway Program.NASA/Bridget Caswell NASA has selected Carlos Garcia-Galan as deputy manager for the Gateway Program. Garcia-Galan previously served as manager of the Orion Program’s European Service Module Integration Office at Glenn Research Center.
“I am tremendously excited to take on this new role and help lead development of humanity’s first outpost in deep space,” Garcia-Galan said. “I’m honored to join a top-class Gateway team around the world, as the first elements of the complex move toward completion.”
Garcia-Galan brings more than 27 years of human spaceflight experience to the role. A native of Malaga, Spain, his career includes supporting assembly of the International Space Station as a flight controller in Houston and Korolev, Russia, during multiple Space Shuttle-International Space Station assembly flights. He joined the Orion program in 2010, serving in a variety of key technical and management roles, including management of integrated spacecraft design and performance, mission analysis, cross-program integration, and launch and flight operations support.
“Carlos is an outstanding manager and engineer, and I am extremely pleased to announce his selection for this position,” said Vanessa Wyche, director of NASA’s Johnson Space Center. “His wealth of experience in human spaceflight, international partnerships, and the development and operations of deep-space spacecraft will be a huge asset to Gateway.”
While with the Orion Program, Garcia-Galan had a key role preparing the Orion team for the Artemis I mission by establishing the Orion Mission Evaluation Room (MER) concept of operations and leading the team through the Artemis I flight preparations until he transitioned into his role managing ESM integration. He later served as one of the Artemis I MER Leads supporting real-time flight operations during the successful Artemis I mission.
“Carlos brings a tremendous technical background and extensive leadership experience that will greatly benefit our program, augmenting our strong team as we progress towards deploying the lunar Gateway,” said Gateway Program Manager Jon Olansen.
Throughout his career, Garcia-Galan has been recognized for his achievements, including receiving, the Honeywell Space Systems Engineer of the Year (Houston) award, the NASA Silver Achievement Medal, the Exceptional Achievement Medal, the Johnson Space Center Director’s Commendation, the Orion Program Manager’s Commendation, and the Silver Snoopy Award.

X-ray: NASA/CXC; Infrared: ESA/Webb, NASA & CSA, P. Zeilder, E.Sabbi, A. Nota, M. Zamani; Image Processing: NASA/CXC/SAO/L. Frattare and K. Arcand Since antiquity, wreaths have symbolized the cycle of life, death, and rebirth. It is fitting then that one of the best places for astronomers to learn more about the stellar lifecycle resembles a giant holiday wreath itself.
The star cluster NGC 602 lies on the outskirts of the Small Magellanic Cloud, which is one of the closest galaxies to the Milky Way, about 200,000 light-years from Earth. The stars in NGC 602 have fewer heavier elements compared to the Sun and most of the rest of the galaxy. Instead, the conditions within NGC 602 mimic those for stars found billions of years ago when the universe was much younger.
This new image combines data from NASA’s Chandra X-ray Observatory with a previously released image from the agency’s James Webb Space Telescope. The dark ring-like outline of the wreath seen in Webb data (represented as orange, yellow, green, and blue) is made up of dense clouds of filled dust.
Meanwhile, X-rays from Chandra (red) show young, massive stars that are illuminating the wreath, sending high-energy light into interstellar space. These X-rays are powered by winds flowing from the young, massive stars that are sprinkled throughout the cluster. The extended cloud in the Chandra data likely comes from the overlapping X-ray glow of thousands of young, low-mass stars in the cluster.
X-ray: NASA/CXC/SAO; Optical: Clow, M.; Image Processing: NASA/CXC/SAO/L. Frattare and K. Arcand In addition to this cosmic wreath, a new version of the “Christmas tree cluster” is also now available. Like NGC 602, NGC 2264 is a cluster of young stars between one and five million years old. (For comparison, the Sun is a middle-aged star about 5 billion years old — about 1,000 times older.) In this image of NGC 2264, which is much closer than NGC 602 at a distance of about 2,500 light-years from Earth, Chandra data (red, purple, blue, and white) has been combined with optical data (green and violet) captured from by astrophotographer Michael Clow from his telescope in Arizona in November 2024.
NASA’s Marshall Space Flight Center in Huntsville, Alabama, manages the Chandra program. The Smithsonian Astrophysical Observatory’s Chandra X-ray Center controls science operations from Cambridge, Massachusetts, and flight operations from Burlington, Massachusetts.

Visual Description
This release includes two composite images, each featuring a star cluster that strongly resembles holiday greenery.
The first image depicts star cluster NGC 602 in vibrant and festive colors. The cluster includes a giant dust cloud ring, shown in greens, yellows, blues, and oranges. The green hues and feathery edges of the ring cloud create the appearance of a wreath made of evergreen boughs. Hints of red representing X-rays provide shading, highlighting layers within the wreath-like ring cloud.
The image is aglow with specks and dots of colorful, festive light, in blues, golds, whites, oranges, and reds. These lights represent stars within the cluster. Some of the lights gleam with diffraction spikes, while others emit a warm, diffuse glow. Upon closer inspection, many of the glowing specks have spiraling arms, indicating that they are, in fact, distant galaxies.
The second image in today’s release is a new depiction of NGC 2264, known as the “Christmas Tree Cluster”. Here, wispy green clouds in a conical shape strongly resemble an evergreen tree. Tiny specks of white, blue, purple, and red light, stars within the cluster, dot the structure, turning the cloud into a festive, cosmic Christmas tree!
