Testing Rover Power System

This image shows the Multi-Mission Radioisotope Thermoelectric Generator for NASA'S Mars 2020 Perseverance rover during a fit check with the rover in the payload processing facility at NASA's Kennedy Space Center in Florida on April 16-17, 2020. The Multi-Mission Radioisotope Thermoelectric Generator is a space nuclear power system that produces about 110 watts of electrical power to run the rover's systems and science instruments, and extra heat to keep them warm during the frigid Martian nights and winter seasons.
