Countdown on for NISAR satellite launch today, a joint NASA-ISRO mission

The NISAR (NASA-ISRO Synthetic Aperture Radar) satellite mission is set for launch today from Sriharikota. The Geosynchronous Satellite Launch Vehicle (GSLV) will carry the 2,392-kg satellite into a 743-km sun-synchronous orbit. NISAR is the first joint satellite mission between NASA and ISRO, designed to scan the entire globe, providing all-weather, day-and-night data at 12-day intervals for a wide range of applications. Officials from both agencies highlighted the strengthened relationship and joint learning achieved during the challenging process of building the satellite across continents amidst a global pandemic.
