Live coverage: Soyuz test flight concludes with landing in Kazakhstan

Fifty years to the day after Neil Armstrong stepped onto the surface of the moon, a NASA astronaut, an Italian flight engineer and a Russian commander geared up for launch aboard a Soyuz spacecraft Saturday on a six-hour flight to the International Space Station.

A Russian Soyuz rocket rolled out to a launch pad in Kazakhstan early Thursday in preparation for liftoff Saturday with a Russian commander, Italian flight engineer and U.S. astronaut heading for the International Space Station.

Expedition 45 commander Scott Kelly and flight engineer Kjell Lindgren have switched their spacesuits to battery power to begin planned six-and-a-half-hour spacewalk Wednesday outside the International Space Station.
