Video: SpaceX launch and landing preview briefing

Isolated camera angle replays of Saturday morning’s predawn SpaceX Falcon 9 launch of the Dragon capsule to the International Space Station.

SpaceX fueled up a Falcon 9 rocket, ran through a mock countdown and fired the booster’s nine Merlin main engines Friday in a successful preflight static fire test officials hope will clear the way for liftoff Jan. 6 on a space station resupply mission.

SpaceX hopes to take a giant leap forward in rocket technology a few minutes after Friday’s scheduled launch of a Falcon 9 booster taking up 2.5 tons of critical supplies and experiments to the International Space Station.
