WASHINGTON — A SpaceX Falcon 9 successfully launched Nov. 21 the latest in a series of satellites developed by the United States and Europe to track rising sea levels.
The Falcon 9 lifted off from Space Launch Complex (SLC) 4 East at Vandenberg Air Force Base in California at 12:17 p.m. Eastern. Its payload, the Sentinel-6 Michael Freilich satellite, separated from the rocket’s upper stage nearly an hour later, after a brief second burn of the upper stage. The rocket’s first stage landed on a pad back at SLC-4.
Sentinel-6 Michael Freilich is the first of two satellites jointly developed by a group of agencies in the United States and Europe, including NASA, NOAA, the European Space Agency, Eumetsat and the European Commission, to provide precise measurements of rising sea levels.
The spacecraft will ensure a continuity of measurements dating back nearly three decades, starting with the TOPEX/Poseidon satellite launched in 1992 and followed by the three Jason spacecraft launched in 2001, 2008 and 2016. Those earlier spacecraft were joint projects of NASA, NOAA, Eumetsat and the French space agency CNES, while Sentinel-6 Michael Freilich is considered part of the Copernicus program of Earth observation satellites by ESA and ...
