NASA has intensified its efforts to ensure the safety and accuracy of the Artemis III lunar landing through advanced lunar illumination simulations at its test center in Huntsville, Alabama. Engineers are replicating the extreme conditions of the lunar South Pole, where the next astronauts will land.
Preparing for the Artemis III lunar landing
At the Marshall Space Flight Center’s Flat Ground Facility, NASA technical teams use powerful 12- and 6-kilowatt light sources and physical mock-ups of a human lander, lunar surface and rocks. The goal: to understand how shadows will affect the visibility and safety of maneuvers during landing.
The test facility, which operates with a surface similar to an inverted air field hockey table, allows heavy structures to be moved without friction, facilitating analysis from multiple angles. This provides valuable data on the light contrast that astronauts will experience when operating in an environment where the Sun is kept at a permanent low angle.
The lunar South Pole is characterized by areas of deep shadow along with intensely illuminated areas. These visual dynamics can make navigation and terrain assessment difficult. The tests allow evaluation of how light impacts colors, the visibility of rocks, and how astronauts will need to adapt to operate in these conditions.
According to Emma Jaynes, test engineer, these simulations provide critical evidence to improve the readiness models that crews will use. “The color white can become blinding in direct sunlight, while shadows cast by structures could reach considerable distances,” she said.
The NASA is collaborating with SpaceX for the development of the Starship human landing system, which will carry astronauts to the lunar surface. The illuminated simulations also help evaluate tools and procedures for the descent stage and surface activities.
With this detailed preparation, NASA seeks to reduce the risks associated with the visual environment and improve the responsiveness of the teams. The Artemis campaign not only marks humanity’s return to the Moon, but paves the way for future missions to Mars.
