<p>Chennai: The Indian Space Research Organisation (ISRO) will on July 30 launch NISAR, a joint mission by the agency and NASA and ISRO aimed at measuring Earth’s changing ecosystems, dynamic surfaces, and ice masses from Sriharikota near here.</p><p>The launch will take place at 5.40 pm on July 30 from the second launchpad of the Sathish Dhawan Space Centre in Sriharikota. GSLV-F16 launch vehicle will inject the NISAR satellite into a 743 km Sun-synchronous orbit with an inclination of 98.40.</p>.ISRO aims at July-end launch for NISAR mission.<p>NISAR, which has been in the works for a decade, provides information about biomass, natural hazards, and groundwater.</p><p>The launch will follow just weeks after Indian Air Force Group Captain Shubhanshu Shukla’s successful return to Earth from the International Space Station (ISS) aboard SpaceX’s Dragon spacecraft—a demonstration of the strong collaboration between India and the US in the space sector.</p>.<p>Weighing 2,392 kg, NISAR is a unique earth observation satellite and the first to observe the earth with a dual frequency Synthetic Aperture Radar (NASA’s L-band and ISRO’s S-band) both using NASA’s 12m unfurlable mesh reflector antenna, integrated to ISRO’s modified I3K satellite bus. </p><p>“NISAR will observe earth with a swath of 242 km and high spatial resolution, using SweepSAR technology for the first time,” the ISRO said. </p><p>The satellite will scan the entire globe and provide all weather, day & night data at 12-day interval and enable a wide range of applications, while it can etect even small changes in the Earth’s surface such as ground deformation, ice sheet movement and vegetation dynamics.</p><p>NISAR carries two radars: the L-band radar developed by ISRO and the S-band radar by NASA’s Jet Propulsion Laboratory (JPL). The entire system was integrated and tested at the U R Rao Satellite Centre in Bengaluru before being transported to Sriharikota.</p><p>NISAR employs a sophisticated information-processing technique known as synthetic aperture radar to produce extremely high-resolution images.</p><p>“Radar penetrates clouds and darkness, enabling NISAR to collect data day and night, in any weather,” ISRO said. “The instrument’s imaging swath—that is, the width of the data strip collected along the orbit track—is greater than 150 miles (240 kilometers), which allows it to image the entire Earth every 12 days,” it added. </p>
