S6 Michael Freilich



The Sentinel-6 Michael Freilich satellite was built by Airbus in Germany and is the size of a small pickup truck. Sentinel-6 Michael Freilich carries a radar altimeter, a microwave radiometer, and instruments to precisely locate the satellite in orbit. Working together, the instruments will track changes in sea level down to a few centimeters.

The mission is a partnership between NASA, the European Space Agency, Eumetsat, and NOAA. The European Commission — the EU’s executive arm — and the French space agency CNES also provided support to the mission.

The Sentinel-6 Michael Freilich satellite is named for the former head of NASA’s Earth science division, who died of cancer earlier this year.
