The launch continues SpaceX’s advancement of the rocket, which is key not only to its ambitions, but also to NASA’s Artemis program. Liftoff from Starbase is set for 7 a.m. CDT (1200 UTC), the start of a 30-minute launch window.

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.

The Starlink 17-28 mission is the 58th mission launching the broadband satellites into low Earth orbit. Liftoff from pad 4E at Vandenberg Space Force Base occurred at 9:39:06 a.m. PDT (12:39:06 p.m. EDT / 1639:06 UTC).
