The NISER (NASA-ISRO Synthetic Aperture Radar) satellite of the joint ISRO-NASA mission, which aims to make global measurements of changes in the Earth’s surface using advanced radar imaging, will be launched in early 2023, the minister said on Friday. of Earth Sciences, Jitendra Singh.
In a written response to a question on the Lok Sabha, he said that NISAR is a joint Earth observation mission between ISRO and the US space agency NASA for global observations over all land masses, including the polar cryosphere and the Ocean region. Indian.
“The NASA-ISRO Synthetic Aperture Radar (NISER) has yet to be launched. NISER is proposed to be launched in early 2023,” said Singh, who is also a minister in the Space Department.
It is a dual-band (L-band and S-band) radar imaging mission with the capability of fully polarimetric and interferometric modes of operation to observe minor changes in land, vegetation, and the cryosphere.
NASA is developing L-band SAR and associated systems, while ISRO is developing S-band SAR, spacecraft bus, launch vehicle and associated launch services, Singh said.
The mission’s main scientific goals are to improve understanding of the impact of climate change on Earth’s changing ecosystems, terrestrial and coastal processes, land deformations and the cryosphere, he said.
NISER is one of the crucial collaborations of ISRO and NASA. India and the United States agreed to this mission during then-President Barack Obama’s visit to India in 2015.
