Videos: Previewing SpaceX’s eighth International Space Station resupply launch

Riding a self-propelled transporter, an Orbital ATK Antares rocket rolled out to it launch pad Thursday on Virginia’s Eastern Shore for final preparations to send a Cygnus supply ship to the International Space Station.

The Starlink 17-12 mission will send the two dozen broadband internet satellites into a polar, low Earth orbit. SpaceX is targeting liftoff from pad 4E at Vandenberg Space Force Base no earlier than Friday, Sept. 19, at 9:31 a.m. PDT (12:31 p.m. EDT / 1631 UTC).

Astronauts Christina Koch and Jessica Meir floated back outside the International Space Station Wednesday for history’s second all-female spacewalk, installing two powerful new lithium-ion batteries on the far left end of the lab’s solar power truss.
