NISAR Satellite Launch Set for March 2025
In March 2025, the Indian Space Research Organisation (ISRO) will launch the NISAR satellite, a milestone in space exploration, the 2.8-tonne satellite will be deployed using the GSLV Mk-II rocket. NISAR represents a collaborative effort between India and the United States, culminating in a ₹5,000-crore project initiated in 2009.

NISAR is a Synthetic Aperture Radar (SAR) satellite. Unlike traditional satellites that capture images with cameras, SAR satellites emit radio signals that bounce back to generate detailed images. This technology allows NISAR to operate effectively in darkness, adverse weather, and dense vegetation.
Development and Collaboration
NASA initially sought a partnership with Germany’s DLR for a new SAR satellite. However, due to scheduling conflicts and budget cuts, NASA turned to ISRO. Impressed by ISRO’s successful missions, including Chandrayaan-1 and RISAT-2, NASA and ISRO officially launched the NISAR mission in 2014.

Monitoring Capabilities
NISAR is engineered to monitor subtle changes in the Earth’s surface. It can detect shifts as minor as one inch, aiding in the assessment of infrastructure like dams and bridges. Furthermore, it will assist in climate change research by tracking ice sheet movements and vegetation changes.

Technical Features
The satellite features a 12-day revisit cycle, allowing it to pass over the same area every twelve days. NISAR employs a swath width of 240 km and a resolution of 10 meters, optimising coverage and image clarity.
