NASA and ISRO are collaborating on developing a satellite "SUV-sized satellite" called NISAR [NASA-ISRO-SAR]. The satellite will be launched in 2022 from the Satish Dhawan Space Center in Sriharikota, India, into a near-polar orbit.
๐น Features:
1. It will scan the globe every 12 days over the course of its three-year mission
2. Take images of the Earth’s land, ice sheets and sea ice to give an “unprecedented” view of the planet.
3. Will detect movements of the planet’s surface as small as 0.4 inches over areas about half the size of a tennis court.
4. NASA will provide one of the radars for the satellite, a high-rate communication subsystem for science data, GPS receivers and a payload data subsystem.
5. ISRO will provide the spacecraft bus, the second type of radar (called the S-band radar), the launch vehicle and associated launch services.
๐น Primary Goals:
1. Tracking subtle changes in the Earth’s surface
2. Spotting warning signs of imminent volcanic eruptions
3. Helping to monitor groundwater supplies
4. Tracking the rate at which ice sheets are melting
Fact: It can help people worldwide better manage natural resources and hazards, as well as providing information for scientists to better understand the effects and pace of climate change.
