STS-133 onboard camera launch video

A refurbished robotic Dragon spaceship rocketed into orbit from Florida on Saturday aboard a SpaceX Falcon 9 launcher, hauling nearly 6,000 pounds of crew provisions and biological, astrophysics and space technology experiments on a two-day trip to the International Space Station.

SpaceX test-fired a Falcon 9 rocket Wednesday afternoon at NASA’s Kennedy Space Center in Florida, clearing a major hurdle before it launches Saturday night — weather permitting — with a four-person crew heading for the International Space Station.

Running nearly two months late after technical concerns prevented liftoff last year, a SpaceX Falcon 9 rocket fired into the sky Sunday night from Cape Canaveral with a top secret payload for the U.S. government, the first of some 30 launches on the company’s docket in 2018.
