Live coverage: Soyuz crew capsule departs station, lands in Kazakhstan

A Russian military communications satellite rode a Soyuz rocket and Fregat upper stage Thursday into an orbit stretching nearly 25,000 miles (40,000 kilometers) above Earth, successfully launching after a one-month delay to replace a suspect third stage on the Soyuz booster.

Four veteran astronauts have been selected to train for launch aboard new commercial crew capsules being built by Boeing and SpaceX that are intended to ferry astronauts to and from the International Space Station starting in 2017, NASA announced Thursday.

Astronaut Scott Kelly and cosmonaut Mikhail Kornienko ended a record-setting 340-day stay in orbit with a fiery plunge to Earth Tuesday, settling to a jarring rocket-assisted touchdown in Kazakhstan to close out a medical research voyage that may help pave the way for flights to Mars.
