Live coverage: 400th Proton rocket takes off with Russian satellite

A European satellite that will collect daily air quality measurements over every major city on Earth rode an uprated Russian ballistic missile into orbit Friday.

Veteran Russian cosmonaut Oleg Kononenko, flanked by Japanese flight engineer Kimiya Yui and NASA astronaut Kjell Lindgren, boarded a Soyuz landing craft Friday and made a parachute-assisted touchdown in Kazakhstan at 1312 GMT (8:12 a.m. EST) to close out more than 141 days on the International Space Station.

These photos chronicle the activities of Russian cosmonaut Fyodor Yurchikhin and NASA astronaut Jack Fischer on Thursday as they prepared for liftoff on a Soyuz rocket to begin an expedition of more than four months on the International Space Station.
