Cosmonauts blast into space
Yi So-yeon is due to return to Earth on April 19, but Russian Flight Commander Sergey Volkov and Flight Engineer Oleg Kononenko, will remain in space for six months.
Before launch they were seen off by famous Russian cosmonauts, Aleksey Leonov and Valentina Tereshkova, the first ever woman in space.
The 17th ISS mission is taking over from Russia’s Yury Malenchenko and American astronaut Peggy Whitson, who will return to Earth with Yi So-yeon.
The Korean cosmonaut, who’s a PhD biology student, will perform a number of experiments during her stay on the ISS.
