Watch the Falcon 9 launch from pad 39A

The Russian Soyuz MS-02 spacecraft carrying two cosmonauts and an American astronaut successfully docks to the International Space Station after a two-day trek from Earth.

The Starlink 6-92 mission also represents the 575th launch of a Falcon 9 rocket to date. SpaceX scheduled liftoff for Monday, Dec. 8, at 5:26 p.m. EST (2226 UTC) following a weather scrub on Sunday.

Engineers working for Spaceflight, a Seattle-based launch services company, are in the final steps of preparing for the first launch of new robotic free flyers carrying more than 70 small government and commercial satellites into polar orbit later this year aboard a dedicated flight of a SpaceX Falcon 9 rocket.
