Live coverage: International Space Station crew lands in Kazakhstan

Three space station fliers — the outgoing NASA commander and two Russian cosmonauts — undocked and returned to Earth Wednesday, ending a 167-day stay in space with a communications blackout that left the crew out of contact with flight controllers during much of the trip home.

An upgraded Soyuz spacecraft, featuring improved navigation, communications and rendezvous systems, blasted into orbit from Kazakhstan Wednesday and set off on a two-day maiden flight to deliver three fresh crew members to the International Space Station.

NASA’s Juno spacecraft barreled toward a Fourth of July rendezvous with Jupiter after a 1.7-billion-mile, five-year trip from planet Earth. The research probe’s main engine ignited for 35 minutes to maneuver Juno into orbit, and engineers received confirmation of the burn’s conclusion on time at 11:53 p.m. EDT Monday (0353 GMT Tuesday).
