India Develops Lunar Environment Test Rig for Space Exploration

Rapid summary

• LESTR Overview: The Lunar Surroundings Structural Test Rig (LESTR) is a NASA-developed tool that simulates lunar night conditions for testing materials adn hardware for Moon and Mars missions.
• Key Features:

– Operates at extreme temperature ranges (40 K to 125 K) in high vacuum (<5×10⁻⁷ Torr). - Uses a cryocooler instead of traditional liquid cryogens for precise thermal control. - Modular design accommodates testing of components like spacesuits, rover wheels, and electronics.

• Specifications:

– Load capacity: ~10 kN; test volume dimensions: 7.5 by 9.5 by 11.5 inches; maximum cycle rate: up to 100 Hz.

• Applications:

– Cryogenic lifecycle testing (fatigue,durability assessments),static load testing,suspension/drivetrain evaluations,textiles analysis,among others.

• Developed by NASA’s glenn Research Center in Cleveland.
