Two Russian cosmonauts and a space flight participant launched aboard a Soyuz spacecraft from the Baikonur Cosmodrome in Kazakhstan at 12:31 p.m. CDT Saturday for a two-day flight to the International Space Station.

Less than 10 minutes after launch their spacecraft reached orbit and its antennas and solar arrays deployed. The Soyuz TMA-10 spacecraft is scheduled to dock at the station at a little after 3 p.m. Monday.

Once they arrive at the station, Cosmonauts Fyodor Yurchikhin, Expedition 15 commander, and Oleg Kotov, Expedition 15 flight engineer, and spaceflight participant Charles Simonyi, a U.S. businessman, will be greeted by the station's current crew, Expedition 14 Commander Michael Lopez-Alegria and flight engineers Mikhail Tyurin and Suni Williams.
