The GSLV F-16 will be the 18th flight of the GSLV and the 12th flight of Mk2 variant using indigenous Cryogenic engine.

Mission Overview

The Preparation work for NISAR's launch started in April 2025 with the flag-off of the GS2 stage.[2] 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, necessating it to be sent back to the US for corrections.[3][4]
