Video: Soyuz MS-01 leaves the space station for landing

Three new residents completed the final leg of their pursuit of the International Space Station, with docking to the complex at 2158 GMT (4:58 p.m. EST) Saturday, two days after blastoff from the Baikonur Cosmodrome in Kazakhstan. The Soyuz capsule carrying the U.S.-Russian-French crew linked up with the research lab’s Rassvet module.

A Russian Soyuz rocket flew into space from the edge of the Amazon on Thursday, carrying a pair of European navigation satellites in the third launch in nine months for the multibillion-dollar Galileo program. Liftoff from French Guiana occurred on time at 1151:56 GMT (6:51:56 a.m. EST).

Concern about a possible ammonia coolant leak Wednesday prompted astronauts on the International Space Station to evacuate the U.S. segment of the complex and shelter in the Russian portion of the outpost while flight controllers scrambled to untangle initially confusing telemetry.
