These photos and videos show how NASA certified a new lander flight training course using helicopters in the mountains of northern Colorado. NASA is partnering with the Colorado Army National Guard at its High-Altitude Army National Guard Aviation Training Site near Gypsum, Colorado, to develop the foundational flight training course that will help astronauts practice flight and landing procedures for the Moon. The certification marks an important milestone in crew training for Artemis missions to the Moon, when astronauts will use a commercial human landing system to land on the lunar surface. During the two-week certification run in late August 2025, NASA astronauts Matthew Dominick and Mark Vande Hei participated in flight and landing training to help certify the course. The pair, along with trained instructor pilots with the Army National Guard, took turns flying a helicopter and navigating to landing zones. Artemis flight crew trainers, mission control leads, and lunar lander operational experts from NASA Johnson joined them on each helicopter flight to assess the instruction, training environment, and technical applications for crewed lunar missions.
