CADRE Team Preps Flight Model for Thermal Testing

Engineers prepare a small rover – part of NASA's CADRE (Cooperative Autonomous Distributed Robotic Exploration) technology demonstration that's headed to the Moon – for testing in the thermal vacuum chamber behind them at the agency's Jet Propulsion Laboratory in Southern California in October 2023. Slated to arrive at the Moon in 2024 as part of NASA's CLPS (Commercial Lunar Payload Services) initiative, CADRE is designed to demonstrate that multiple robots can cooperate and explore together autonomously – without direct input from human mission controllers. A trio of the miniature solar-powered rovers, each about the size of a carry-on suitcase, will explore the Moon as a team, communicating via radio with each other and a base station aboard a lunar lander. By taking simultaneous measurements from multiple locations, CADRE will also demonstrate how multirobot missions can record data impossible for a single robot to achieve – a tantalizing prospect for future missions. The rover being tested is the first flight model to be completed. Thermal vacuum testing simulates the harsh environment the rovers will face on the journey to the Moon and on the lunar surface: All the air is pumped out of the chamber and the temperature is cycled to high and low extremes. https://photojournal.jpl.nasa.gov/catalog/PIA25670
