INDIA: National Aeronautical and Space Administration (NASA) and Indian Space Research Organization (ISRO) have jointly developed the world’s first earth observation satellite with two different radars that can produce very high-resolution images.
The ISRO has teamed up with NASA to develop a highly reflective radar for satellite observations. With this radar, more clear images of the earth will be taken.
ISRO has achieved a key milestone by making the S-band Synthetic Aperture Radar (SAR) and shipping it to NASA integration with the L-band payload being developed by the US agency.
Once the integration of the two radars is done, NASA will send them to India where other parts of the NASA-ISRO SAR (NISAR) satellite will be built.
NISAR is the first campaign for two different vibrations A band and S-band. The partnership agreement was signed between NASA and the Indian Space Research Organization in Bengaluru on September 30, 2014. The mission will start in 2022 and the satellite will be sent with radar from Sriharikota in the Nellore district of Sriharikota.
NASA has set up an L-band SAR and provided scientific information and GPS servers. It includes a solid-state recorder, an IS band radar provided by ISRO, and will cover the Earth’s surface. The S-band SAR payload is part of the Nisar satellite mission and has already been approved by the space department.
The payload is being sent to Sriharikota from ISRO’s Space Deployment Center in Ahmedabad, while NASA’s Jet Propulsion Laboratory has developed an L-band SAR payload. Discovering the causes of natural disasters, the ‘Nisar’ satellite will closely monitor changes in the Earth’s ice sheets and other natural elements.
The causes of natural disasters such as earthquakes, tsunamis, volcanoes, and landslides will be investigated using this radar. NASA has decided to monitor the Earth’s surface and ice cover every twelve days.
“The three-year mission will provide images of the Earth every six days,” NASA said.
