Video: Zoomed in view of ignition of Falcon 9 engines in prelaunch test (members only)

Ready for a flight to the International Space Station, SpaceX’s first upgraded Dragon cargo capsule rolled out to pad 39A at NASA’s Kennedy Space Center in Florida this week in preparation for launch on top of a Falcon 9 rocket.

Watch the pre-launch news conference held Thursday at NASA’s Kennedy Space Center to preview liftoff of the agency’s TDRS-M data relay satellite aboard a United Launch Alliance Atlas 5 rocket from Cape Canaveral.

SpaceX is readying two Falcon 9 rockets for a pair of flights nine hours apart Sunday from separate pads along Florida’s Space Coast. Weather permitting, the back-to-back departures Sunday would mark shortest span between two orbital-class launches from Cape Canaveral since 1966.
