ISRO Launches NISAR On GSLV-F16

Successful launch of #GSLV-F16 carrying the world’s first dual-band radar satellite, NISAR. Regarded as a game-changer satellite, it is capable of providing information for precise management of disasters like cyclones, floods, etc. Capable of penetrating through fog, dense clouds, ice layers, etc., it is a pathbreaking enabler for the aviation and shipping sectors.

Dr. Jitendra Singh, Union Minister of Science & Technology, quoted,

The inputs from NISAR will benefit the entire world community…in the true spirit of “ Vishwabandhu.” 

Mission Overview

The GSLV F-16 is the 18th flight of the GSLV and the 12th flight of the Mk2 variant using an indigenous cryogenic engine. The preparation work for NISAR's launch started in April 2025 with the flag-off of the GS2 stage. Initially scheduled for an early 2024 launch, the mission was delayed after it was decided to apply special reflective coatings to its primary radar reflectors, necessitating it to be sent back to the US for corrections.

Launch Vehicle

This launch vehicle is an 3-stage launch vehicle. The first stage of GSLV was also derived from the PSLV's PS1. The 138 tonne solid rocket motor is augmented by 4 liquid strap-ons which is powered by a Vikas rocket engine.

Payload

The NISAR mission is a $1.5 billion Earth-observation satellite developed in collaboration with NASA. It will deploy one of the world's most advanced radar imaging systems to monitor Earth's changing systems and natural hazards.
