MOSCOW (Sputnik) — The Falcon 9 rocket lifted off from Vandenberg Air Force Base in California at 05:37 local time (12:37 GMT).
The first stage separated from the rocket and landed on the "Just Read The Instructions" floating drone ship in the Pacific Ocean nearly 8 minutes after the launch.

The second stage reached preliminary parking orbit and continued the mission of taking the satellites to the orbit.
SpaceX conducts flights to deliver supplies to the International Space Station under contract with NASA, as well as commercial launches of satellites. At the moment, the space company is developing the technology for the multiple use of the rocket carrier by landing the first stage of Falcon 9 on air bases and floating drone ships in the Atlantic and Pacific oceans. The company believes that the repeated use of the first stage of rockets would cut the cost of space flights.
