Watch the Falcon 9 launch from pad 39A

A Russian Progress supply ship loaded with more than 3 tons of supplies and equipment bound for the International Space Station apparently spun out of control shortly after reaching orbit Tuesday, putting the resupply mission in jeopardy while flight controllers scrambled to come up with a fix.

SpaceX rolled out the company’s first space-worthy Crew Dragon spacecraft and its Falcon 9 launcher to pad 39A at NASA’s Kennedy Space Center in Florida for the first time Thursday, beginning a series of fit checks before the commercial spaceship takes off on its first orbital test flight.

An upgraded Soyuz ferry ship, the second in a new series featuring improved avionics, navigation and other systems, glided to a flawless docking with the International Space Station early Friday, bringing three fresh crew members to the outpost and briefly boosting the lab’s crew back to six.
