ISRO Successfully Launches NISAR Earth Monitoring Satellite, Built With Help of NASA

The world’s most expensive Civilian Earth Imaging Satellite Nisar was successfully launched from Sriharikota in Andhra Pradesh on Wednesday to monitor the earth. This satellite is created by the Indian Space Research Organization (ISRO) with the American Space Agency NASA.

NISAR (NASA-ISRO synthetic apartheer radar satellite) was told by ISRO in a tweet on social media platform x that 5:40 PM (according to Indian time) has been launched from Satish Dhawan Space Center in Sriharikota in Andhra Pradesh. For this, spacecraft of pickup truck size has been used. After reaching the orbit of this satellite, its dual-frequency radar will revolve around the earth 14 times a day. This will scan all land and snow surfaces on the earth every 12 days. This is the first collaboration between ISRO and NASA.

ISRO reported in a post on social media platform X that GSLV-F16 has been successfully launched with NISAR. This will make it easier for scientists to monitor soil moisture. Along with this, threats like landslides and floods can be better assessed. ISRO Chairman, V Narayanan said that this is a major step towards playing India’s leading role in satellite technology. He said, “We were dependent on other countries for satellite technology for many years since the launch of India’s first satellite, Aryabhata. This satellite can also record changes as 1 centimeters on the surface of the earth.

NASA’s Jet Propulsion Laboratory (JPL) has created a long-wavelend L-band radar for NISAR. The Space Applications Center of India has built the short-wavelend S-band radar of this satellite. From this dual-frequency design, NISAR is the first meaning satellite with two radar systems. This satellite will provide important information about dangers like melting glacier on earth and rising sea levels.
