NISAR Launch

Coverage of the Launch of NISAR, an Earth-observing satellite and the first collaborative mission between NASA and ISRO (Indian Space Research Organisation)

ISRO’s GSLV-F16 will launch ISRO-NASA joint satellite, NISAR, on July 30, 2025

NASA-ISRO Synthetic Aperture Radar (NISAR), the first joint satellite of ISRO and NASA will be launched by ISRO’s GSLV-F16 on July 30, 2025 at 1740 hrs IST from Satish Dhawan Space Centre (SDSC SHAR), Sriharikota. GSLV-F16 will inject the NISAR satellite into a 743 km Sun-synchronous orbit with an i...

NISAR (NASA-ISRO Synthetic Aperture Radar)

Overview

Destination: Sun-Synchronous Orbit
Mission: Earth Science

Sun-Synchronous Orbit Satish Dhawan Space Centre Second Launch Pad Satish Dhawan Space Centre, India

The NASA-ISRO Synthetic Aperture Radar, or NISAR satellite, will use advanced radar imaging to map the elevation of Earth's land and ice masses 4 to 6 times a month at resolutions of 5 to 10 meters. It is designed to observe and measure some of the planet's most complex natural processes, including ecosystem disturbances, ice-sheet collapse, and natural hazards such as earthquakes, tsunamis, volcanoes and landslides. Under the terms of the agreement, NASA will provide the mission's L band synthetic aperture radar (SAR), a high-rate telecommunication subsystem for scientific data, GPS receivers, a solid-state recorder, and a payload data subsystem. ISRO will provide the satellite bus, an S band synthetic aperture radar, the launch vehicle, and associated launch services.

GSLV Mk II

Family:
Configuration:

Geosynchronous Satellite Launch Vehicle Mark II (GSLV Mk II) is the largest launch vehicle developed by India, which is currently in operation. This fourth generation launch vehicle is a three stage vehicle with four liquid strap-ons. The indigenously developed cryogenic Upper Stage (CUS), which is flight proven, forms the third stage of GSLV Mk II. From January 2014, the vehicle has achieved four consecutive successes.
