A Soyuz spacecraft carrying two Russian cosmonauts and the first South Korean astronaut docked with the ISS Thursday morning. The Soyuz TMA-12 spacecraft docked with the Pirs airlock module of the station at 8:57 am EDT (1257 GMT) Thursday, two days after launch from Baikonur. The spacecraft is carrying the two Russian members of the ISS Expedition 17 crew, Sergei Volkov and Oleg Kononenko, who will spend the next six months on the ISS. Also on the spacecraft is Yi So-yeon, the first South Korean to fly in space. She will return to Earth on April 19 on the Soyuz TMA-11 spacecraft already docked on the ISS with returning ISS crew members Yuri Malenchenko and Peggy Whitson.
