3 Min Read NASA Engineers Simulate Lunar Lighting for Artemis III Moon Landing
Better understanding the lunar lighting environment will help NASA prepare astronauts for the harsh environment Artemis III Moonwalkers will experience on their mission. NASA’s Artemis III mission will build on earlier test flights and add new capabilities with the human landing system and advanced spacesuits to send the first astronauts to explore the lunar South Pole and prepare humanity to go to Mars.
Using high-intensity lighting and low-fidelity mock-ups of a lunar lander, lunar surface, and lunar rocks, NASA engineers are simulating the Moon’s environment at the Flat Floor Facility to study and experience the extreme lighting condition. The facility is located at NASA’s Marshall Space Flight Center in Huntsville, Alabama.
NASA engineers inside the Flat Floor Facility at Marshall Space Flight Center in Huntsville, Alabama, mimic lander inspection and assessment tasks future Artemis astronauts may do during Artemis III. Lights are positioned at a low angle to replicate the strong shadows that are cast across the lunar South Pole. NASA/Charles Beason “The goal is really to understand how shadows will affect lander visual inspection and assessment efforts throughout a future crewed mission,” said Emma Jaynes, test engineer at the facility. “Because the Flat Floor Facility is similar to an inverted air hockey table, NASA and our industry partners can rearrange large, heavy structures with ease – and inspect the shadows’ effects from multiple angles, helping to ensure mission success and astronaut safety for Artemis III.”
Data and analysis from testing at NASA are improving models Artemis astronauts will use in preparation for lander and surface operations on the Moon during Artemis III. The testing also is helping cross-agency teams evaluate various tools astronauts may use.
The 86-foot-long by 44-foot-wide facility at NASA is one of the largest, flattest, and most stable air-bearing floors in the world, allowing objects to move across the floor without friction on a cushion of air.
Test teams use large, 12-kilowatt and 6-kilowatt lights to replicate the low-angle, high contrast conditions of the lunar South Pole. Large swaths of fabric are placed on top of the epoxy floor to imitate the reflective properties of lunar regolith. All the mock-ups are placed on air bearings, allowing engineers to easily move and situate structures on the floor.
The Flat Floor Facility is an air-bearing floor, providing full-scale simulation capabilities for lunar surface systems by simulating zero gravity in two dimensions. Wearing low-fidelity materials, test engineers can understand how the extreme lighting of the Moon’s South Pole could affect surface operations during Artemis III. NASA/Charles Beason “The Sun is at a permanent low angle at the South Pole of the Moon, meaning astronauts will experience high contrasts between the lit and shadowed regions,” Jaynes said. “The color white can become blinding in direct sunlight, while the shadows behind a rock could stretch for feet and ones behind a lander could extend for miles.”
The laboratory is large enough for people to walk around and experience this phenomenon with the naked eye, adding insight to what NASA calls ‘human in-the-loop testing.
NASA is working with SpaceX to develop the company’s Starship Human Landing System to safely send Artemis astronauts to the Moon’s surface and back to lunar orbit for Artemis III.
Through the Artemis campaign, NASA will send astronauts to explore the Moon for scientific discovery, economic benefits, and to build the foundation for the first crewed missions to Mars – for the benefit of all.

Acting NASA Administrator Janet Petro and Anke Kaysser-Pyzalla, chair, Executive Board, DLR (German Aerospace Center, or Deutsches Zentrum für Luft- und Raumfahrt), signed an agreement June 16, 2025, to continue a partnership on space medicine research. With this agreement, DLR will provide new radiation sensors aboard the Orion spacecraft during NASA’s Artemis II mission. Scheduled for launch no later than April 2026, Artemis II will mark the first test flight with crew under Artemis.Credit: DLR While attending the Paris Air Show June 16, NASA acting Administrator Janet Petro signed an agreement with DLR (German Aerospace Center, or Deutsches Zentrum für Luft- und Raumfahrt) to continue a partnership in space medicine research. This renewed collaboration builds on previous radiation mitigation efforts for human spaceflight. As NASA advances the Trump-Vance Administration’s goals for exploration on the Moon and Mars, minimizing exposure to space radiation is one of the key areas the agency is working to protect crew on long duration missions.
With this agreement, DLR will leverage its human spaceflight expertise and provide new radiation sensors aboard the Orion spacecraft during NASA’s Artemis II mission, building on previous work in this area during the Artemis I mission. Scheduled for launch no later than April 2026, Artemis II will mark the first test flight with crew under Artemis.
“In keeping with the historic agreements NASA has made with international partners as a part of Artemis, I am pleased to sign a new NASA-DLR joint agreement today, to enable radiation research aboard Artemis II,” said acting NASA Administrator Janet Petro. “The German Aerospace Center has been a valuable partner in Artemis, having previously worked with NASA to test technology critical to our understanding of radiation on humans aboard an Orion spacecraft on Artemis I and providing a CubeSat as part of Artemis II. Following a productive meeting between President Trump and German Chancellor Merz earlier this month, I am excited to build upon our great partnership with Germany.”
During the Artemis II mission’s planned 10-day journey around the Moon and back, four of DLR’s newly developed M-42 extended (M-42 EXT) radiation detectors will be on board, contributing vital data to support astronaut safety. This next-generation device represents a new phase of research as NASA and DLR continue working together to safeguard human health in space.
Under the leadership of President Trump, America’s Artemis campaign has reignited NASA’s ambition, sparking international cooperation and cutting-edge innovation. The continued partnership with DLR and the deployment of their advanced M-42 EXT radiation detectors aboard Artemis II exemplifies how the Trump-Vance Administration is leading a Golden Era of Exploration and Innovation that puts American astronauts on the path to the Moon, Mars, and beyond.
“To develop effective protective measures against the impact of space radiation on the human body, comprehensive and coherent radiation measurements in open space are essential,” says Anke Pagels-Kerp, divisional board member for space at DLR. “At the end of 2022, Artemis I carried 12,000 passive and 16 active detectors inside the Helga and Zohar mannequins, which flew aboard the Orion spacecraft as part of DLR’s MARE project. These provided a valuable dataset – the first continuous radiation measurements ever recorded beyond low Earth orbit. We are now excited to take the next step together with NASA and send our upgraded radiation detectors around the Moon on the Artemis II mission.”
Through the Artemis campaign, the agency will establish a long-term presence on the Moon for scientific exploration with our commercial and international partners, learn how to live and work away from home, and prepare for future human exploration of Mars.
