According to NASA, LESTR is the first mechanical test rig that avoids challenges associated with cryogenic fluids. The team has been testing yarns for future spacesuits and developing advanced materials for rover tires, including a shape-memory metal that returns to its original shape after being deformed. Technical lead Ariel Dimston said that LESTR operates in a completely dry vacuum, eliminating the need for specialized handling equipment and safety systems.
"By leaving behind the liquid cryogen, you no longer need specialized handling equipment such as dewers, wet heaters, nor valves," Dimston stated. The exact cost comparison with traditional methods and the timeline for mission use have not been disclosed.
