The NASA-ISRO Synthetic Aperture Radar (NISAR) satellite is scheduled to be launched by 2022. This was scheduled after India and the US decided to share Space Situational Awareness Information with each other. This would catalyse efforts in order to create the conditions for a safe and sustainable space environment.
The space agencies of both the countries had signed an agreement in 2014 in order to conduct the joint NISAR mission. The mission was to launched in order to co-develop and launch a dual-frequency synthetic aperture radar on the Earth observation satellite.
The NASA-ISRO Synthetic Aperture Radar (NISAR) mission is a joint project of NASA and ISRO. It has been started to co-develop and launch a dual-frequency synthetic aperture radar on the Earth observation satellite. It will be the first radar imaging satellite that uses the dual frequencies. The satellite would be launched from India on a Geosynchronous Satellite Launch Vehicle on a Sun-synchronous orbit.
The satellite would be used for remote sensing, to observe and understand natural processes on Earth. The satellite would use advanced radar imaging for mapping the elevation of Earth’s land and ice masses 4 to 6 times a month. It has been designed to observe and measure complex natural processes including ecosystem disturbances, ice-sheet collapse and natural hazards like earthquakes, Landslides, tsunamis and volcanoes on the Earth.
