Updated February 14th at 8pm EST (0100 UTC): SpaceX has postponed the T-0 launch time.

SpaceX continues its busy weekend with the launch of its 600th Falcon 9 rocket to date. The milestone mission comes hours after the Dragon spacecraft arrived at the International Space Station as part of its 20th human spaceflight mission.

The Starlink 17-13 mission is scheduled to lift off from Vandenberg Space Force Base on Saturday night. It will send 24 Starlink V2 Mini satellites into low Earth orbit.

Launch from Space Launch Complex 4 East is scheduled for the end of the launch window at 5:59:59 PM PT (8:59:59 PM ET/0159:59 UTC). Once the rocket leaves the pad, it will fly in a southerly trajectory.

Spaceflight Now will begin broadcasting live approximately 30 minutes before launch.



SpaceX will use a Falcon 9 first stage booster with tail number 1081 to launch this mission. This will be its 22nd flight after launching four missions specifically for NASA: Crew-7, CRS-29, PACE, and TRACERS.

More than eight minutes after liftoff, B1081 aims to land on the drone ship “Of Course I Still Love You,” located in the Pacific Ocean. If successful, it would be the 178th landing on the ship and the 571st booster landing for SpaceX to date.

Earlier in the day, SpaceX’s Crew Dragon spacecraft, named Freedom, arrived at the ISS at 3:15 pm ET (2015 Universal Time). The three astronauts and one astronaut arrived in orbit about 34 hours after liftoff from Pad 40 at Cape Canaveral Space Force Station.
