NASA has certified a helicopter-based lander training course in Colorado’s Rocky Mountains to prepare Artemis astronauts for Moon missions. The high-altitude terrain creates lunar-like visual illusions, forcing pilots to master landings in dusty, slope-filled conditions. Over two dozen astronauts have now trained in this challenging, realistic simulation.NASA has certified a helicopter-based lander training course in Colorado’s Rocky Mountains to prepare Artemis astronauts for Moon missions.
