Watch the SpaceX Falcon 9 rocket launch the EchoStar 23 satellite

The U.S. Air Force’s fourth Advanced Extremely High Frequency spacecraft launched Wednesday from Cape Canaveral on top of a United Launch Alliance Atlas 5 rocket, expanding the reach of the military’s most secure, jam-resistant satellite communications network.

A Northrop Grumman Cygnus supply ship carrying more than 7,200 pounds of provisions and experiments approached the International Space Station two days after its launch from Virginia, moving close enough for capture by the station’s robotic arm at 5:28 a.m. EST (1028 GMT) Monday.

SpaceX technicians offloaded a Dragon cargo capsule from its recovery ship Thursday after returning the thrice-flown supply freighter to the Port of Los Angeles, marking the final planned return of a Dragon spacecraft to the West Coast.
