The Indian Space Research Organization (ISRO) has received the NASA-ISRO SAR (NISAR) satellite from the US space agency. NISAR is a low earth orbit observatory jointly developed by NASA and ISRO.
According to ISRO, NISAR will map the entire Earth in 12 days and provide spatially and temporally consistent data to understand changes in Earth’s ecosystems, ice mass, vegetation biomass, sea level rise, groundwater and earthquakes, tsunamis, volcanoes and landslides. .
NISAR L and S carry dual-band synthetic aperture radar (SAR), which works with the sweep SAR technique to acquire large swaths with high-resolution data. The Integrated Radar Instrument Structure (IRIS) and the SAR payloads mounted on the spacecraft bus are collectively called the observatory.

Last month, NASA said that starting in early 2021, engineers and technicians at the Jet Propulsion Laboratory (JPL) in Southern California will integrate and test NISAR’s two radar systems — the L-band SAR provided by JPL and the S-band SAR built by ISRO.
The US space agency said the SUV-sized payload would be transferred to a special cargo container for the 14,000 km flight to Bengaluru.
Final integration of the satellite will be done at the UR Rao Satellite Center in Bengaluru and ISRO plans to launch the satellite from the Satish Dhawan Space Center in Sriharikota in 2024.
