Photos: Atlas 5 rocket aims for International Space Station

An electrical problem on SpaceX’s drone ship parked just off the coast of Cape Canaveral prompted SpaceX to scrub a Falcon 9 launch attempt early Friday, delaying the start of a resupply mission to the International Space Station by 24 hours.

Three Chinese military satellites launched Saturday aboard a Long March 4C rocket, joining six others China has sent into orbit since the start of the year on ocean surveillance missions.

SpaceX’s 19th Dragon resupply mission to the International Space Station ended Tuesday with the capsule’s splashdown in the Pacific Ocean southwest of Los Angeles with nearly 3,600 pounds of cargo and experiments.
