ISRO, NASA join hands for NISAR satellite to track disasters, impact of climate change
FirstpostSeven years since it was first envisioned, a car-sized earth observation satellite is under development in a joint effort by the National Aeronautics and Space Administration and the Indian Space Research Organisation.

NISAR is an earth observation satellite that will help us understand the causes and consequences of changes taking place on land, using advanced radar imaging. According to a NASA statement, the US space agency requires a ‘minimum of three years with the L-band radar’, while ISRO will use the S-band radar to study parts of India and the Southern Ocean for five years. On 19 March, ISRO sent the S-band radar to NISAR’s assembly, test, and launch team at JPL in order for it to be attached to the satellite.
