Video: Last minute technical problem scrubs Falcon 9 launch

The U.S. Air Force announced Tuesday that SpaceX is now eligible to compete for launches of U.S. national security satellites, closing a tumultuous chapter in the U.S. rocket industry and ending the Pentagon’s sole reliance on United Launch Alliance to haul military payloads into orbit.

A SpaceX Dragon supply ship departed the International Space Station and returned to Earth Tuesday to conclude its third round-trip flight to the orbiting research outpost, bringing home a spacesuit, mice and and numerous experiments.

SpaceX plans to launch its next group of Starlink broadband satellites aboard a Falcon 9 rocket as soon as Tuesday, Jan. 21, from Cape Canaveral, two days after the company is scheduled to launch a modified Falcon 9 booster from a separate facility at the Florida spaceport to test the Crew Dragon spaceship’s emergency escape system.
