The SpaceX Dragon cargo ship loaded with supplies, crew provisions, new science experiments and an experimental expandable module for the International Space Station arrived Sunday morning for rendezvous, capture and berthing.

NASA simulated an in-flight launch abort of an Orion crew capsule high above Cape Canaveral on Tuesday, in a major test of the safety system that would whisk astronauts on future moon missions away from a failing rocket.

SpaceX launched a Falcon 9 rocket from Cape Canaveral at 4:10 p.m. EDT (2010 GMT) Tuesday on the company’s first mission dedicated to the newly-established U.S. Space Force. The Falcon 9 carried a GPS navigation satellite into orbit.
