STS-133 onboard camera launch video

SpaceX called off a Falcon 9 countdown Wednesday due to the threat of lightning from thunderstorms along Florida’s Space Coast, pushing back the departure of a cargo mission for the International Space Station until Thursday.

These photos show SpaceX’s Falcon 9 rocket, with a previously-flown first stage booster, sitting on its launch pad Tuesday at Vandenberg Air Force Base in California ahead of the scheduled liftoff of the Radarsat Constellation Mission.

A sophisticated combat-ready U.S. military missile warning satellite moved to its launch pad at Cape Canaveral Space Force Station Saturday on top of a United Launch Alliance Atlas 5 rocket, ready for liftoff Monday afternoon.
