A few hours ago, the Sentinel-6B satellite was launched atop a Falcon 9 rocket from the Vandenberg base. After about 57 minutes, it successfully separated from the rocket’s last stage and set off on its course to reach the polar orbit at 1,336 kilometers altitude where its scientific mission will begin, taking over from the Sentinel-6A Michael Freilich satellite, which was launched on November 21, 2020.
