Live coverage: Two satellites lift off aboard Ariane 5

Two U.S. astronauts flanked a veteran Russian cosmonaut Thursday for a ride back to Earth from the International Space Station. The trio undocked from the station in their Soyuz spacecraft at 0757 GMT (3:57 a.m. EDT), beginning a return flight that culminated in a parachute-assisted landing on the steppe of Kazakhstan at 1145 GMT (7:45 a.m. EDT).

United Launch Alliance fired an Atlas 5 rocket into space from Cape Canaveral at 9:14 a.m. EDT (1314 GMT) Sunday with the U.S. Air Force’s X-37B spaceplane, an automated reusable mini-space shuttle designed to host experiments for years in orbit, then return to Earth and land on a runway. A launch attempt Saturday was scrubbed by bad weather.

Two U.S.-built communications satellites for Dish Network television subscribers and Indonesian banking customers fired into orbit from French Guiana aboard an Ariane 5 rocket Saturday, setting the record for the European launcher’s heaviest commercial payload.
