SpaceX is gearing up for launch of an unpiloted Crew Dragon spacecraft from the Kennedy Space Center for a crucial test of the crew capsule’s launch abort system. A modified Falcon 9 rocket performed a test-firing at launch pad 39A Saturday before carrying the Crew Dragon spacecraft into the upper atmosphere for an in-flight abort test scheduled for Jan. 18.

SpaceX called off a planned launch attempt Saturday to deploy the next batch of satellites for the Starlink broadband network. Two commercial Earth-observing satellites for BlackSky are also awaiting a ride into orbit on the Falcon 9 rocket from pad 39A at the Kennedy Space Center in Florida.
