Preparations for Next Moonwalk Simulations Underway (and Underwater)<\/h1>\n<\/div>\n<\/div>\n<\/div>\n

The Lunar Environment Structural Test Rig simulates the intense cold of the lunar night, ranging from 40 Kelvin (K) to 125 K while maintaining a vacuum environment. This creates a tool by which scientists and engineers can test materials, electronics, and flight hardware for future Moon and Mars missions, characterizing their behaviors at these temperatures while also validating their ability to meet design requirements.<\/p>\n

Facility Overview<\/strong><\/h2>\n

The Lunar Environment Structural Test Rig (LESTR) approaches the problem of creating a simulated lunar environment by departing from typical fluid immersion or jacketed-and-chilled chamber systems. It does this by using a cryocooler to reject heat and bring the test section to any point desired by the test engineer, as low as 40 K or as high as 125 K in a vacuum environment. By combining high vacuum and cryogenic temperatures, LESTR enables safe, accurate, and cost-effective testing of materials and hardware destined for the Moon and beyond. Its modular setup supports a wide range of components \u2014 from spacesuits to rover wheels to electronics \u2014 while laying the foundation for future Moon and Mars mission technologies.<\/p>\n

Quick Facts<\/strong><\/h2>\n

LESTR is a cryogenic mechanical test system built up within a conventional load frame with the goal of providing a tool to simulate the thermal-vacuum conditions of the lunar night to engineers tasked with creating the materials, tools, and machinery to succeed in NASA\u2019s missions.<\/p>\n
