SpaceX successfully launched a satellite into orbit and landed part of a rocket on Thursday.
The two-stage Falcon 9 rocket lifted off from the Kennedy Space Center in Florida -- and delivered a communications satellite into orbit for the nation of Qatar.
The first rocket stage then safely landed on a droneship in the Atlantic Ocean.
The drone ship has a cute name -- "Of Course I Still Love You."
It was the second successful landing for that rocket. The first was in July.
