Time-lapse: Watch the Crew Dragon and Falcon 9 roll to the launch pad (members only)

SpaceX’s Falcon 9 rocket closed out a busy 2017 Cape Canaveral launch schedule on Dec. 15 with a successful liftoff on a space station resupply mission. The Falcon 9’s first stage booster, making its second launch, returned to Florida’s Space Coast for an on-target landing.

NASA hopes to begin launching astronauts to the space station aboard Boeing and SpaceX capsules in the 2017 timeframe, but managers expect to still send crews up aboard Russian spacecraft as a hedge against problems that could force some astronauts to make an emergency landing.

SpaceX is targeting Saturday for launch of its next space station resupply mission from Cape Canaveral after a problem with an upper stage steering system actuator flared up during a countdown Tuesday.
