The Falcon 9 lifted off from Cape Canaveral Space Force Station in Florida on Tuesday at 11:38 p.m. EDT (0338 GMT Sept. 20), carrying 22 of SpaceX's Starlinkinternet satellites toward low Earth orbit (LEO).

The rocket's first stage came back to Earth 8.5 minutes after launch, landing on a SpaceX drone ship stationed at sea.

It was the 17th liftoff and landing for this Falcon 9's first stage, according to a SpaceX mission description. Those figures are unprecedented; the previous mark was 16, held by two different Falcon 9 boosters.
