Live coverage: Dragon completes space station resupply flight

The mission, dubbed Tranche 1 Transporter Layer C, will add another 21 satellites into the burgeoning constellation for the Space Development Agency. Liftoff from pad 4E at Vandenberg Space Force Base happened Wednesday, Oct. 15, at 4:06 p.m. PDT (7:06 p.m. EDT / 2306 UTC).

SpaceX struck out for a third time in as many days attempting to launch the Starlink 10-2 mission. After pushing back the launch time a few times within their window of availability on Friday, an abort was called just as the Merlin engines at the base of the 70-meter-tall (299 feet) rocket ignited.

SpaceX’s Falcon 9 rocket is set for liftoff from Cape Canaveral on Thursday evening, heading due east over the Atlantic Ocean to deliver the BulgariaSat 1 communications satellite into orbit 35 minutes later.
