NASA and ISRO's NISAR mission uses complementary L-band and S-band synthetic-aperture radars to track changes in Earth's land, ice, and ecosystems. After launch into a 747-kilometer sun-synchronous orbit, the spacecraft deployed and commissioned its 12-meter radar reflector before entering its science phase for systematic global observations.
