NASA-ISRO NISAR satellite, first joint earth observation mission, to launch on July 30
NISAR (NASA-ISRO Synthetic Aperture Radar), the first joint satellite developed by NASA and ISRO, is scheduled for launch on July 30 from Satish Dhawan Space Centre in Sriharikota. The GSLV-F16 rocket will inject the 2,392 kg satellite into a 743-km sun-synchronous orbit. NISAR is a unique earth observation satellite, being the first to observe Earth with a dual-frequency Synthetic Aperture Radar (NASA's L-band and ISRO's S-band). It will use SweepSAR technology to scan the globe, providing all-weather, day-and-night data at 12-day intervals for applications like ground deformation, ice sheet movement, vegetation dynamics, sea ice classification, and disaster response.
