New Delhi, July 30 :India is planning to launch in early 2023 the NISER (NASA-ISRO Synthetic Aperture Radar) satellite to measure land surface changes across the globe using advanced radar imaging.

NISAR is a joint Earth-Observation mission between ISRO and NASA for global observations over all landmasses, including the Polar cryosphere and the Indian Ocean region.

“It is a dual-band (L-band and S-band) Radar imaging mission with the capability of full polarimetric and interferometric modes of operation to observe minor changes in land, vegetation, and cryosphere,” Science and Technology Minister Jitendra Singh said in the Lok Sabha.

NASA is developing L-band SAR and associated systems and ISRO is developing S-band SAR, spacecraft bus, the launch vehicle, and associated launch services.

The major scientific objectives of the mission are to improve understanding of the impact of climate change on Earth’s changing Ecosystems, land, and coastal processes, land deformations, and Cryosphere, said the minister.(UNI)
