NISAR: Pioneering the Future of Earth Observation

The NASA-ISRO joint satellite NISAR, set for a July 30 launch, aims to enhance Earth observation. Utilizing advanced SweepSAR technology, it promises high-resolution global scans, revealing Earth's surface changes and supporting various applications like disaster response and shoreline monitoring. The collaboration marks a decade-long technical partnership.

The NASA-ISRO joint satellite NISAR is scheduled for a landmark launch from the Satish Dhawan Space Centre, Sriharikota, at 5.40 pm on July 30, announced the space agency on Monday.

Equipped with cutting-edge SweepSAR technology, NISAR will be positioned in a 743 km Sun-synchronous orbit through the use of GSLV-F16, delivering unprecedented Earth observation capabilities. It will oversee Earth's surface with a broad 242 km swath and deliver high-resolution imagery.

The satellite’s advanced capabilities will offer data on surface changes, supporting applications such as storm characterization, sea ice classification, and disaster response. Weighing 2,392 kg, NISAR pioneers dual-frequency Synthetic Aperture Radar technology, the product of over a decade of technical cooperation between ISRO and NASA.
