Watch the Falcon 9 launch from pad 39A

A prototype rocket for a massive reusable vehicle SpaceX is designing to fly people to the moon and Mars took off from a launching stand in South Texas on Tuesday, flew to a height of roughly 500 feet, then made a controlled descent to a nearby landing pad.

Closing out an automated 18-hour rendezvous, a SpaceX Dragon cargo ship loaded with 7,000 pounds of supplies and equipment, including two add-on roll-out solar blankets, caught up with the International Space Station early Tuesday and moved in for a problem-free docking.

SpaceX successfully deployed 60 more Starlink internet satellites in orbit Saturday, continuing a record launch cadence while engineers assess a concern with Falcon 9 rocket engines that has delayed other missions, including the next crew flight to the International Space Station.
