Video: Falcon 9 fires up engines for static fire test (members only)

In a fiery, dramatic comeback for SpaceX, a Falcon 9 rocket took off from Cape Canaveral, streaking into orbit as its booster stage returned to a historic landing on Florida’s Space Coast in a key achievement aimed at slashing the cost of space transportation. Eleven communications satellites for Orbcomm were deployed in orbit in the flight’s prime objective.

This is the pre-launch news conference held Dec. 2 at NASA’s Kennedy Space Center for liftoff of the Orbital ATK commercial Cygnus cargo ship aboard a United Launch Alliance Atlas 5 rocket for the International Space Station.

Veteran astronauts Soichi Noguchi and Shannon Walker have been assigned to fly to the International Space Station on SpaceX’s second piloted Crew Dragon mission later this year, joining commander Mike Hopkins and astronaut Victor Glover on a planned six-month expedition in orbit.
