Advancing Spacesuit Technology: NASA’s Thermal Vacuum Tests for Artemis III Moonwalks
By Monika LuabeyaApril 24, 2025
NASA continues to push the boundaries of human space exploration. They are refining the technology that will enable astronauts to safely operate in the harsh lunar environment. This is crucial for the upcoming Artemis III mission. Engineers recently conducted rigorous thermal vacuum testing on a spacesuit glove. This glove is an essential component of the Extravehicular Mobility Unit (EMU). The glove was tested in extreme conditions within CITADEL. This stands for Cryogenic Ice Testing, Acquisition Development, and Excavation Laboratory. It is a specialized chamber at NASA's Jet Propulsion Laboratory (JPL) in Southern California.
Pushing the Limits: Testing in Lunar-Like Conditions
On November 1, 2023, NASA engineers placed the EMU glove in vacuum conditions. They exposed it to ultra-low temperatures of minus 352 degrees Fahrenheit (minus 213 degrees Celsius). These environmental extremes closely simulate...
