Watch the Falcon Heavy roar to life

Boeing’s Starliner capsule, carrying an instrumented astronaut test dummy nicknamed “Rosie,” is on track for launch Friday on an unpiloted test flight to the International Space Station, mission managers said Tuesday. The flight is a major milestone in NASA’s push to resume launching U.S. crews from American soil.

SpaceX’s Falcon 9 rocket is set for liftoff from Cape Canaveral on Monday, heading due east over the Atlantic Ocean to deliver the Koreasat 5A communications satellite into orbit around 36 minutes later.

SpaceX fired up a Falcon 9 booster at Cape Canaveral’s Complex 40 launch pad Wednesday in advance of a space station resupply launch Dec. 12, returning the pad to service after a rocket explosion there last year.
