The first launch this year carried a special payload - Zuma, a secretive spacecraft commissioned by the USA government for an undisclosed mission.
Neither SpaceX nor the USA military have disclosed the goal of the Zuma craft, but the news site says the satellite was created by aerospace firm Northrop Grumman.
Last night's launch is SpaceX's first of the year and its 20th first stage landing to date. The news has been announced by founder Elon Musk.
After two months of mysterious delays, SpaceX has finally launched its Falcon 9 rocket to deliver the top-secret Zuma spacecraft into the low-Earth orbit.More news: Oakland Raiders Officially Announce Jon Gruden Is Back As Head Coach

Such landings are part of SpaceX's efforts to develop fully reusable rockets, which the company believes could bring down spaceflight costs.
Up next, SpaceX is set to launch it's Falcon Heavy rocket for the first time at the end of the month, carrying a Tesla auto as its first payload as the company looks at commercial and government launches later this year, and even missions to the moon and Mars eventually.
Falcon Heavy was vertical on the Kennedy Space Center launch pad 39A last week for the first time.
Sometime early this year, the Falcon Heavy is set to launch a Arabsat satellite built by Lockheed.
