NASA will provide live coverage of launch activities for NISAR (NASA-ISRO Synthetic Aperture Radar), which is set to lift off at 8:10 a.m. EDT (5:40 p.m. IST), Wednesday, July 30, from Satish Dhawan Space Centre on India’s southeastern coast.
A collaboration between NASA and the Indian Space Research Organisation (ISRO), the first-of-its-kind satellite will lift off aboard an ISRO Geosynchronous Satellite Launch Vehicle on a mission to scan nearly all the Earth’s land and ice surfaces twice every 12 days.
Watch live coverage of the launch on NASA+ and the agency’s YouTube channel. Learn how to watch NASA content through a variety of platforms, including social media.
With its two radar instruments — an S-band system provided by ISRO and an L-band system provided by NASA — the NISAR mission will provide high-resolution data to help decision-makers, communities, and scientists monitor major infrastructure, agricultural fields, and movement of land and ice surfaces.

The NISAR mission is the first joint satellite mission between NASA and ISRO, marking a new chapter in the growing collaboration between the two space agencies. The launch of NISAR, years in the making, builds on a strong heritage of successful programs, including Chandrayaan-1 and the recent Axiom Mission-4, which saw ISRO and NASA astronauts living and working together aboard the International Space Station for the first time.
