Copernicus Sentinel-6 Michael Freilich: almost time for liftoff

Copernicus Sentinel-6 Michael Freilich safely tucked up in the Falcon 9 rocket on the launch pad at the Vandenberg Air Force Base in California, US. Once launched, this new mission will take the role of radar altimetry reference mission, continuing the long-term record of measurements of sea-surface height started in 1992 by the French–US Topex Poseidon and then the Jason series of satellite missions.
