Nisar GSLV-F16 mission: When and how to watch joint Nasa-Isro mission launch
The Indian Space Research Organisation (Isro) is all set to launch the ambitious Nasa Isro Synthetic Aperture Radar (Nisar) Mission to over a period of nearly 10 years, the $1.5 billion mission is one of the most expensive developed jointly by the two space agencies. Nisar mission's primary objectives are to study land & ice deformation, land ecosystems, and oceanic regions in areas of common interest to the US and Indian science S-band radar system, data handling system, high-speed downlink system, the spacecraft, and the launch vehicle have been developed by Isro.
Nasa has contributed the L-band radar system, an additional high-speed downlink system, a solid-state recorder, a GPS receiver, and a 9-meter boom that supports the 12-meter radar reflector. Isro is responsible for satellite commanding and operations, while Nasa will provide the orbit manoeuvre plan and the radar operations WILL NISAR LAUNCH?The Nisar mission will lift-off aboard Isro's Geosynchronous Launch Vehicle-Mk II (GSLV-Mk II) from the Satish Dhawan Space Centre in launch is scheduled for July 30 at 5:40 pm the lift-off the satellite will be deployed into space aftere 18 minutes of flight.

The unique dual-band SAR employs advanced, novel SweepSAR technique, which provides high resolution and large swath imagery. NISAR will image the global land and ice-covered surfaces, including islands, sea-ice and selected oceans every 12 TO WATCH NISAR LAUNCH?India Today Science will bring you all the updates of the launch LIVE from Indian space agency, Isro, and the American space agency Nasa will live stream the launch. You can watch it here. WHAT HAPPENS AFTER DEPLOYMENT? The NISAR mission will progress through four key phases: Launch, Deployment, Commissioning, and Science is scheduled to launch aboard the GSLV-F16 rocket on July 30, 2025, from Isro's Satish Dhawan Space Centre in Sriharikota.

In the Deployment Phase, a 12-meter reflector will be extended 9 meters from the satellite using a complex boom designed by Nasa/JPL. The 90-day Commissioning Phase involves system checks, calibrations, and instrument Science Operations Phase will continue until the mission ends, featuring regular orbit maneuvers, instrument observations, and joint Isro-JPL coordination for calibration, validation, and science data collection.- EndsMust Watch
