Video: Falcon 9 test-fired before fourth Starlink launch (members only)

SpaceX currently has more than 9,500 Starlink satellites in low Earth orbit. Liftoff of the Starlink 17-19 mission from pad 4E at Vandenberg Space Force Base happened at 9:53:20 a.m. PST (12:53:20 p.m. EST / 1753:20 UTC).

A SpaceX Falcon 9 rocket carrying a Dragon cargo ship loaded with more than 4,000 pounds of supplies and equipment bound for the International Space Station — including a critical docking adapter needed by future U.S. crew ships — broke apart in a shower of debris shortly after launch Sunday.

Two-and-a-half days after launch from Virginia, a Northrop Grumman Cygnus supply ship arrived at the International Space Station Tuesday with nearly 7,500 pounds of cargo. Capture with the station’s robotic arm occurred at 4:05 a.m. EST (0905 GMT).
