NISAR will provide scientists with valuable data as it monitors ice-sheet changes, sea-level rises, ecosystems shifts and more. According to NASA, the satellite will scan forests and wetlands and study both human-driven and natural changes to these environments.

The US space agency NASA has launched a satellite into space in collaboration with the Indian Space Research Organization (ISRO) designed to measure changes on the Earth's surface at levels of precision previously unknown.

Synthetic Aperture Radar (NISAR) is the costliest earth observation satellite till date, with an investment of $1.5 billion
