NASA’s Human Landing System: Testing Insulation for Artemis Moon Missions
- NASA’s Human Landing System (HLS) will take astronauts to the Moon, marking a historical event with the first woman and the first person of color in Artemis III.
- Engineers at NASA’s Marshall Space Flight Center in Huntsville, Alabama, are testing prototype insulation for SpaceX’s Starship HLS.
- Rene Ortega, HLS chief engineer, stated that the HI-TTeMP lab helps determine how well materials will insulate liquid oxygen and methane propellants.
NASA’s Human Landing System (HLS) will take astronauts to the Moon, marking a historical event with the first woman and the first person of color in Artemis III. The mission focuses on reliability and safety in challenging environments.
Engineers at NASA’s Marshall Space Flight Center in Huntsville, Alabama, are testing prototype insulation for SpaceX’s Starship HLS. This lander will transport astronauts during Artemis III and Artemis IV. Marshall’s HI-TTeMP laboratory evaluates insulation materials for deep space missions.
Rene Ortega, HLS chief engineer, stated that the HI-TTeMP lab helps determine how well materials will insulate liquid oxygen and methane propellants. Early feedback aids in design and development for deep space missions.
The Moon presents extreme temperatures. At the south pole during the lunar night, temperatures can drop to -370°F (-223°C). In direct sunlight, temperatures can reach 250°F (120°C), while shadows can be just above absolute zero.
Thermal management uses two methods: active and passive. Passive controls include insulation, white paint, and thermal blankets. Active controls use radiators and cryogenic coolers.
NASA engineers in the HI-TTeMP lab simulate deep space conditions using two vacuum chambers. One chamber assesses radiant heat from the Sun, and the other measures conduction by evaluating heat transfer paths.
The HI-TTeMP lab not only conducts tests but also provides thermal engineering insights to partners like SpaceX. This collaboration helps validate designs and speeds up testing of updates.
NASA’s HLS Program, led by Marshall, aims to land astronauts safely on the Moon. Contracts for Artemis III and IV have been awarded to SpaceX, and Blue Origin has been selected for Artemis V. Both will transfer cryogenic propellant in space to launch landers with full tanks.
With Artemis, NASA aims to explore the Moon more than ever, learn to operate away from Earth, and prepare for future Mars missions. The Space Launch System, Orion spacecraft, and Gateway lunar space station are key to NASA’s deep space exploration framework.
