Video: Falcon 9 test-fired before space station cargo launch (members only)

These photos show a 194-foot-tall United Launch Alliance Atlas 5 rocket standing on pad 41 at Cape Canaveral Space Force Station in advance of a planned launch with the U.S. Space Force’s fifth SBIRS missile warning satellite.

The mission is the first that will populate the 13th group of Starlink satellites in SpaceX’s megaconstellation. Liftoff from pad 39A at NASA’s Kennedy Space Center happened at 12:24 a.m. EST (0524 UTC).

The International Space Station’s robotic arm, under the control of engineers on Earth, extracted an experimental inflatable habitat from the trunk of SpaceX’s Dragon supply ship Saturday and attached it to the orbiting complex.
