Photos: Falcon takes flight

NASA has decided to launch the multibillion-dollar Europa Clipper mission — a spacecraft to study a moon of Jupiter with an icy crust covering a liquid water ocean — aboard a commercial heavy-lift rocket in October 2024, and not on the government-owned Space Launch System, officials said Wednesday.

The Falcon 9 rocket launching the Starlink 15-13 mission will fly on a south-easterly trajectory upon leaving pad 4E at Vandenberg Space Force Base. Liftoff is for 7:27 a.m. PST (10:27 a.m. EST / 1527 UTC).

SpaceX technicians are attaching a Japanese communications satellite to the top of a Falcon 9 rocket ahead of a planned launch Thursday morning from Cape Canaveral.
