NISAR Testing

A component of the NASA-ISRO Synthetic Aperture Radar (NISAR) satellite sits inside a thermal vacuum chamber at NASA's Jet Propulsion Laboratory during testing in August 2020. The chamber simulates the harsh conditions of space to ensure the hardware can withstand the mission's environment. A joint mission between NASA and the Indian Space Research Organisation (ISRO), NISAR will track Earth's surface changes down to fractions of an inch to monitor volcanic activity, groundwater levels, ice sheet melt rates, and vegetation changes.
