ISRO has released the first S-Band Synthetic Aperture Radar images from the joint NASA-ISRO NISAR mission. The data covers diverse global regions and is intended to assist in environmental monitoring and coastal resource management.
Why it matters
The NISAR mission represents a significant technological collaboration that provides high-resolution Earth observation data for climate and environmental research.
BENGALURU: Long after the launch of the NASA- ISRO Synthetic Aperture Radar (SAR)- NISAR- mission, the ISRO shared the first set of images taken using the S-Band SAR. The colour-coded images included Nagapattinam district in Tamil Nadu, East of Antarctica, Brahmaputra River in Assam, Idaho in USA , Greenland and Indonesia.Earlier on September 25, 2025, NASA-Jet Propulsion Laboratory (JPL) had shared the first set of images taken using the L-Band SAR. These images were shared within 90 days of the launch of mission, the scheduled time for the full-science operation term to commence.The joint mission of NASA-JPL and ISRO was launched on July 30, 2025, using the GSLV-F16 from Satish Dhawan Space Centre in Sriharikotta. While NASA will receive 35 tetrabyte, the National Remote Sensing Centre will receive 8-tetrabyte data and the Antarctica Centre will also receive data.
