The U.S. and India just launched NISAR, a powerful radar satellite that will be able to monitor changes in Earth's surface that are as small as a centimeter.

NASA and India have paired up to launch an Earth-mapping satellite capable of tracking the slightest changes in land and ice.

After integration, IRIS was shipped to India for integration into the NISAR satellite at the U R Rao Satellite Centre (URSC) in Bengaluru. URSC finished NISAR before ISRO moved the satellite to the launch site, and the payload arrived at the Satish Dhawan Space Centre on June 12.
