Before astronauts return to the Moon’s surface through NASA’s Artemis program, the hardware they depend on must first prove it can survive the unforgiving lunar environment. At NASA’s Johnson Space Center in Houston, engineers at the Lunar Development and Test Facility are tackling one of exploration’s biggest challenges: Moon dust.
Unlike sand on Earth, lunar dust is sharp, abrasive, and clings to nearly everything. Without mitigation, lunar dust could damage equipment and spacesuits while posing health risks to astronauts. Understanding and mitigating the effects of lunar dust is essential as astronauts prepare to live and work on the surface of the Moon.
Located within the Energy Systems Test Area and managed by NASA engineers, the Lunar Development and Test Facility supports the development and testing of hardware in simulated lunar conditions. Engineers evaluate systems and subsystems inside vacuum chambers using lunar regolith simulant to better understand how spacesuits, spacecraft components, and mechanisms with moving parts and joints will perform during future Artemis missions.
NASA Johnson’s Propulsion and Power Division developed specialized systems that make the facility’s lunar simulations possible. The facility includes a dust containment and preparation laboratory for ambient testing, a 3-foot cube vacuum chamber, and a 15-foot thermal vacuum chamber.
