Full form<\/strong><\/td>\nNASA-ISRO Synthetic Aperture Radar (NISAR)<\/td>\n<\/tr>\n
About<\/strong><\/td>\n1. NISAR is a satellite jointly developed by NASA and ISRO for Low Earth Orbit (LEO) observation.<\/span>
\n2. It is an SUV-size satellite weighing around 2,800 kilograms.<\/td>\n<\/tr>\n
Objective<\/strong><\/td>\n1. Tracking subtle changes<\/span> in the Earth\u2019s surface.
\n2. Spotting warning signs of imminent volcanic eruptions<\/span>.
\n3. Helping to monitor groundwater supplies<\/span>.
\n4. Tracking the rate at which ice sheets are melting<\/span>.<\/td>\n<\/tr>\n
Launch year<\/strong><\/td>\nIt was launched on July 30th, 2025 from Satish Dhawan Space Centre, Sriharikota in Andhra Pradesh.<\/td>\n<\/tr>\n
Mission life<\/strong><\/td>\nThree years<\/td>\n<\/tr>\n
Function<\/strong><\/td>\n1. It will capture images of Earth’s land, ice sheets<\/span>, and sea ice every 12 days.<\/span>
\n2. It will be able to detect the earth\u2019s surface movement as small as 0.4 inches over an area.<\/td>\n<\/tr>\n
Features<\/strong><\/td>\n1. It is a dual frequency satellite<\/span> (L-band and S-band).
\nNote<\/strong>– NASA contributed the L-band radar, GPS, solid-state recorder, and payload data subsystem, while ISRO supplied the S-band radar<\/span>, GSLV launch system and spacecraft.
\n2. Another crucial part of the satellite is its large 39-foot fixed antenna reflector<\/span>. It will be used to focus ‘the radar signals emitted and received by the upward-facing feed on the instrument structure’.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

What is the significance of this mission?<\/strong><\/h2>\n

1. Earth observation<\/strong>– It will offer detailed observations of Earth’s surface<\/span>, tracking changes in ice sheets, land deformation, and ecosystems<\/span>. This data will improve our understanding of Earth’s processes and aid in tackling environmental challenges.<\/p>\n

2. Disaster Management<\/strong>– The mission offers vital data for managing natural disasters like earthquakes, tsunamis, and volcanic eruptions. This will enhance response time and risk assessments.<\/span><\/p>\n

3. Agriculture- <\/strong>NISAR data will enhance agriculture management and food security<\/span> by offering insights into crop growth, soil moisture, and land-use changes.<\/p>\n

4. Climate Change- <\/strong>It will aid in monitoring and understanding climate change’s impacts on Earth’s land surface<\/span>, including glacier melting, sea-level rise, and carbon storage changes.<\/p>\n
