Blue Origin's MK1 lunar lander, also known as Endurance, is an uncrewed cargo spacecraft designed to test key technologies for future Moon missions. The vehicle is part of a commercial demonstration effort aimed at strengthening Human Landing System capabilities for NASA's Artemis program.
The project highlights a growing public-private collaboration model. Blue Origin carried out testing through a reimbursable Space Act Agreement with NASA, using agency facilities and expertise to accelerate development.
Testing Critical Moon Landing Technologies
Endurance is built to validate several essential systems needed for operating on the lunar surface. These include precision landing, cryogenic propulsion, and autonomous guidance, navigation, and control.
Alongside these demonstrations, the lander will also deliver two NASA payloads to the Moon's South Pole region this year under the CLPS (Commercial Lunar Payload Services) initiative. One payload, the Stereo Cameras for Lunar Plume-Surface Studies, will capture high-resolution images of how the lander's engine plume interacts with the lunar surface during descent and landing. The second, the Laser Retroreflective Array, will help orbiting spacecraft determine precise locations by reflecting laser signals.
