NISAR Satellite Launches to Map Earth's Surface Changes

The article announces the launch of the NISAR satellite, a joint NASA-ISRO mission to map Earth’s surface changes with unprecedented detail.

  • The US$1.2-billion NISAR satellite launched from Sriharikota, India, will scan nearly the entire planet every 12 days, measuring vertical ground shifts as small as one centimetre using dual radar instruments from NASA and ISRO.
  • The mission aims to improve disaster response by providing rapid data on floods, earthquakes, and landslides, and is slated to operate for at least three years, though future Earth-observing missions face potential budget cuts from the US government.
