NASA and the Indian Space Research Organisation said the joint NISAR Earth-observing satellite is now scheduled to lift off no earlier than 30 July 2025. Officials detailed the plan during a briefing on Monday, setting a target launch time of 5:40 p.m. Indian Standard Time (8:10 a.m. Eastern) from ISRO’s Satish Dhawan Space Centre aboard a Geosynchronous Launch Vehicle. Short for NASA-ISRO Synthetic Aperture Radar, NISAR will be the first spacecraft to carry both L- and S-band synthetic-aperture radar instruments, enabling it to map nearly all of the planet’s land and ice surfaces twice every 12 days. The mission is expected to generate high-resolution data on changes in ecosystems, ice sheets, earthquakes and volcanoes, helping scientists monitor the pace of climate-driven transformations with unprecedented detail.
