In a written response to a question in the Lok Sabha, he said, "NASA-ISRO Synthetic Aperture Radar (NISER) has not been launched yet. NISER is proposed to be launched in early 2023."
 
It should be noted that NISAR is a joint Earth observation mission between ISRO and NASA. NISAR will be used for global observations over all land masses including the Polar cryosphere and the Indian Ocean region. It aims to measure changes in the earth’s surface globally using advanced radar images.
 
 
 
This is a dual-band (L-band and S-band) radar imaging mission with full polarimetric and interferometric modes of operation for observing small changes in land, vegetation, and cryosphere.
 
Singh further informed that, as per the mission, NASA is developing L-band SAR and associated systems, while ISRO is developing S-band SAR, spacecraft bus, the launch vehicle, and associated launch services.
 
He added that 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.
