The first joint satellite of the Indian and American space agencies is now set for launch.
Isro said Monday that NASA-ISRO Synthetic Aperture Radar (Nisar) on July 30 at 5:40 PM from Satish Dhawan Space Center (SDSC Shar), Sriharikota from Isro will be launched by Isro’s GSLV-F16. The mission has been in the making for more than ten years now.
The GSLV-F16 launch vehicle will inject the Nisar satellite into a 743 km of sun-synchrone course with a slope of 98.4 degrees, the Indian Space Agency said. Nisar will scan the earth every 12 days and with high resolution, daily data for all weather conditions. It will observe the earth with a strip of 242 km and a high spatial resolution, with the help of Sweepsar technology for the first time, Isro said.
Nisar, with a weight of 2,392 kg, is a unique earth observation satellite and the first satellite to observe the earth with a synthetic apture radar with double frequency (NASA’s L-band and Isro’s s-tire), both using NASA’s 12m in the esrodic-Reflallantantna.
Nisar is able to detect small changes in the earth’s surface, such as ground distortion, ice roof movement and vegetation dynamics. The other applications include sea -ice classification, ship detection, coastline monitoring, storm characterization, changes in soil moisture, mapping and monitoring of surface water springs and disaster response.
