A series of events occur after launch. The SpaceX Falcon 9 rocket’s first stage main engine will cut off, followed by separation from the second stage. The second stage will ignite, followed by payload fairing jettison from the Sentinel-6 satellite. The second stage will cut off and then restart to put the satellite in the proper trajectory. About a minute later, the second stage will cut off and the Sentinel-6 will separate from the second stage. The Falcon 9 first stage will return through Earth’s atmosphere for a vertical landing.
