NASA announced Monday that the launch of the first operational crew rotation mission to the International Space Station on SpaceX’s Crew Dragon spacecraft is set for the predawn hours of Halloween, eight days later than previously planned.

The United Launch Alliance Atlas 5 rocket blasted off Thursday night with NASA’s Magnetospheric Multiscale satellite quartet in a successful flight from Cape Canaveral.

The Starlink 17-9 mission added another 24 broadband satellites to its low Earth orbit constellation of more than 8,300. Liftoff from pad 4E at Vandenberg Space Force Base happened at 11:06 a.m. PDT (2:06 p.m. EDT / 1806 UTC).
