Live coverage: Cygnus supply ship captured by space station robot arm

SpaceX’s Dragon supply ship departed the International Space Station on Wednesday, fired rocket thrusters to brake out of orbit, and parachuted to a picture-perfect splashdown in the Pacific Ocean with approximately 3,461 pounds of experiment samples and equipment.

Blasting into space atop an Ariane 5 launcher, two communications satellites started missions Sunday to beam broadband services to ships, airplanes and offshore oil rigs for a commercial Norwegian operator and relay signals for the Italian and French armed forces.

A communications satellite developed in a public-private partnership between Luxembourg government and SES is set for launch Tuesday aboard a previously-flown SpaceX Falcon 9 booster from Cape Canaveral, ready for a 15-year mission beaming encrypted, jam-resistant signals for security and military forces across Europe, Africa and the Middle East.
