Sentinel-1 in orbit

Sentinel-1A is ESA’s first satellite dedicated to Europe’s environmental monitoring Copernicus programme.

Carrying an advanced radar, it will scan Earth’s surface no matter what the weather and regardless of whether it is day or night. In crisis situations, it will be used for rapid response to disasters such as floods and earthquakes. Its radar will routinely monitor shipping zones, map sea ice and provide information on winds and waves for marine traffic, track changes in the way land is being used, and monitor subsidence.
