Video: Antares rocket returns to flight with new engines

The Soyuz MS-07 spacecraft carrying U.S., Russian and Japanese space fliers returned to Earth on Sunday with a parachute-assisted, rocket-cushioned touchdown on the Kazakh steppe after 168 days in orbit.

United Launch Alliance teams at Cape Canaveral hoisted a Centaur upper stage on top of an Atlas 5 rocket Friday at launch pad 41, completing the initial build-up of the launch vehicle slated to carry Boeing’s Starliner crew capsule into space in December on an unpiloted test flight to the International Space Station.

The first launch of Boeing’s Starliner space capsule aboard a United Launch Alliance Atlas 5 rocket has been delayed to Dec. 19, officials announced Tuesday.
