Live coverage: Dragon completes space station resupply flight

A team of SpaceX engineers is building a prototype of the spaceship Elon Musk hopes will one day carry people and cargo deep into the solar system, and it could begin low-altitude testing next year, kicking off a multi-step test campaign before eventually going into space, then perhaps the moon or Mars.

Stormy weather near NASA’s Kennedy Space Center kept SpaceX’s Falcon 9 rocket on the ground Thursday, delaying liftoff of a commercial supply ship with equipment and experiments for the International Space Station until Saturday.

SpaceX crews at Vandenberg Air Force Base in California rolled out a Falcon 9 rocket and lifted it vertical atop its launch pad ahead of a planned blastoff Wednesday with a Spanish radar observation satellite and two test probes for a planned global broadband Internet network.
