Major Earth Satellite to Track Disasters, Effects of Climate Change

The S-band SAR, one of two kinds of radar on the NISAR mission, arrived at JPL on March 19. The next day, technicians and engineers moved the S-SAR into the airlock to the Spacecraft Assembly Facility’s High Bay 1 clean room. The equipment will be unpacked over several days in the clean room. (Credits: NASA/JPL-Caltech)

Designed to spot potential natural hazards and help researchers measure how melting land ice will affect sea level rise, the NISAR spacecraft marks a big step as it takes shape.

PASADENA, Calif. (NASA PR) — An SUV-size Earth satellite that will be equipped with the largest reflector antenna ever launched by NASA is taking shape in the clean room at the agency’s Jet Propulsion Laboratory in Southern California. Called NISAR, the joint mission between NASA and the Indian Space Research Organization (ISRO) has big goals: By tracking subtle changes in Earth’s surface, it will spot warning signs of imminent volcanic eruptions, help to monitor groundwater supplies, track the melt rate of ice sheets tied to sea level rise, and observe shifts in the distribution of vegetation around the world. Monitoring these kinds of changes in the planet’s surface over nearly the entire globe hasn’t been done before with the high resolution in space and time that NISAR will deliver.
