Blue Origin Moon Lander Completes Testing at NASA Vacuum Chamber
Blue Origin's Blue Moon Mark 1 (MK1) lunar lander, also known as Endurance, has completed environmental testing in NASA's Thermal Vacuum Chamber A at Johnson Space Center. The uncrewed cargo lander will demonstrate key technologies such as precision landing and autonomous navigation, and will carry two NASA science payloads to the Moon's South Pole. The testing supports NASA's Artemis program and advances development of future crewed lunar landing systems.
- ▪Blue Origin’s Blue Moon MK1 lunar lander completed thermal vacuum testing at NASA’s Johnson Space Center.
