The rocket was previously in February to take cargo to the International Space Station (ISS).
The flight marks the third time Elon Musk’s company has successfully reused a rocket (the company first achieved this engineering milestone back in March) and the 18th time SpaceX’s have successfully landed a rocket.
The rocket’s landed on a SpaceX drone ship “Of Course I Still Love”.
The launch mission was to deploy new satellites for use by SES and EchoStar.
SpaceX long-term goa is to reach a stage where rockets can be turned around, ready for launch again, in 24 hours.
