<\/a><\/figure>Also known as Endurance, MK1 is an uncrewed cargo lander funded by Blue Origin as a commercial demonstration mission to advance Human Landing System capabilities in support of NASA\u2019s Artemis program. The tests in Chamber A represent a public-private partnership model, with Blue Origin conducting work through a reimbursable Space Act Agreement.<\/p>\n<\/p>\n
Endurance will demonstrate precision landing, cryogenic propulsion, and autonomous guidance, navigation, and control capabilities in support of future lunar surface operations. In addition to its primary objectives, MK1 will carry two NASA science and technology payloads<\/a> under the CLPS (Commercial Lunar Payload Services) initiative to the lunar South Pole region this year: the Stereo Cameras for Lunar Plume-Surface Studies, an array of high-resolution cameras that will collect imagery of the interaction between the lander\u2019s engine plume and the lunar surface during descent and landing, and the Laser Retroreflective Array, which helps orbiting spacecraft determine a more precise location using reflected laser light.<\/p>\n<\/p>\n Through CLPS, NASA partners with American companies to deliver science investigations and technology demonstrations to the Moon, advancing understanding of the lunar environment and supporting future crewed missions as part of the agency\u2019s Artemis campaign.<\/p>\n<\/p>\n Testing in NASA Johnson\u2019s Chamber A, one of the world\u2019s largest thermal vacuum test facilities, enabled engineers to model the vacuum of space and the extreme temperature conditions the spacecraft would experience during flight. By recreating these conditions on the ground, teams evaluated system performance and verified structural and thermal integrity prior to launch. NASA and Blue Origin will incorporate lessons learned from MK1\u2019s design, integration, and testing to support NASA\u2019s future Artemis missions<\/a> that will return American astronauts to the Moon.<\/p>\n<\/p>\n MK1\u2019s development contributes to technology maturation and risk reduction for future human-class systems, including Blue Moon Mark 2 (MK2), a larger crewed landing system designed to safely transport astronauts from lunar orbit to the surface and back, enabling sustained human exploration at the Moon\u2019s South Pole region.<\/p>\n Testing of MK1 at NASA Johnson is enabled through the agency\u2019s \u201cfront door<\/a>\u201d approach \u2014 a coordinated process that provides commercial partners access to NASA facilities and technical expertise while maintaining safety, mission assurance, and alignment with agency objectives.<\/p>\n<\/p>\n More information about Thermal Vacuum Chamber A is available at https:\/\/www.nasa.gov\/setmo\/facilities\/thermal-vacuum-chamber-a\/<\/a>\u00a0<\/p>\n Powered by WPeMatico<\/a><\/small><\/p>\n Get The Details…<\/a> Also known as Endurance, MK1 is an uncrewed cargo lander funded by Blue Origin as a commercial demonstration mission to advance Human Landing System capabilities in support of NASA\u2019s Artemis program.
