Photos: Falcon takes flight

An interplanetary space weather station rocketed away from Cape Canaveral aboard a SpaceX Falcon 9 rocket Wednesday, speeding toward a remote operating post a million miles from Earth to help forecasters warn of intense solar storms.

The launch came amid the return of three astronauts and a cosmonaut from the International Space Station. Liftoff from pad 40 at Cape Canaveral Space Force Station 3:57 p.m. EDT (1957 UTC).

SpaceX’s first Falcon 9 Block 5 rocket, sporting changes to make the booster easier to reuse, rolled out of its hangar and up the ramp to launch pad 39A at NASA’s Kennedy Space Center on Thursday ahead of a planned hold-down engine firing.
