NASA-ISRO joint mission NISAR to be launched on July 30; live coverage will be available.

The Synthetic Aperture Radar (NISAR) mission, jointly developed by NASA and the Indian Space Research Organisation (ISRO), will be launched on Wednesday, July 30. The launch is scheduled for 5:40 PM from the Satish Dhawan Space Centre, located on the southeastern coast of India.

The satellite will be launched into space aboard ISRO’s Geosynchronous Satellite Launch Vehicle (GSLV). The primary objective of the NISAR mission is to scan most of Earth's land and ice-covered surfaces twice every 12 days.

Live Broadcast:
The live coverage of the launch will be available on NASA's official platforms including NASA+ and its YouTube channel. Real-time updates and additional information will also be accessible through NASA’s website and its social media accounts:

Mission Significance:
The NISAR mission features two radar instruments: the S-band system provided by ISRO and the L-band system provided by NASA. This dual-band system allows the mission to deliver high-resolution data. These data will be highly useful in monitoring infrastructure, agriculture, movements of land and ice surfaces, and in disaster preparedness and response to events such as cyclones, floods, and volcanic eruptions.

During a visit to Washington in February, U.S. President Trump and Indian Prime Minister Modi praised the NISAR mission as a pivotal moment in U.S.–India civil space cooperation.

Pre-Launch Teleconference:
A teleconference will be held on Monday, July 28 at 9:30 PM IST, ahead of the launch. The session will include:

Karen St. Germain, Earth Science Division Director, NASA HQ

Gerald Bawden, NISAR Program Scientist

Shanna McClain, Disasters Program Manager

Phil Barela, NISAR Project Manager, JPL

Marco Lavalle, Deputy Project Scientist

The teleconference will be streamed live on JPL’s YouTube channel.

NISAR is the first joint satellite mission between NASA and ISRO, marking a new chapter in the growing partnership between the two space agencies. It follows a series of successful programs including Chandrayaan-1 and the recent Axiom Mission-4.
