Live coverage: SpaceX delivers joint SES/EchoStar satellite to orbit

SpaceX’s Falcon 9 rocket is awaiting liftoff from Cape Canaveral’s Complex 40 launch pad as soon as Tuesday after three scrubs caused by propellant loading problems and a boat that strayed into restricted waters in the Atlantic Ocean.

It didn’t go into space, but SpaceX’s Dragon crew capsule fired off a launch pad at Cape Canaveral on Wednesday for a 99-second test flight to demonstrate a crucial safety mechanism that would save astronauts from a catastrophic rocket failure.

A solid-fueled Minotaur 4 rocket lifted off from Wallops Island, Virginia at 9:46 a.m. EDT (1346 GMT) Wednesday. The four-stage rocket, comprised of retired Peacekeeper missile parts, launched on a mission to deliver four classified payloads into orbit for the National Reconnaissance Office.
