MOSCOW , Russia ( CNN ) -- Russian space officials say the crew of the Soyuz space ship is resting after a rough ride back to Earth . A South Korean bioengineer was one of three people on board the Soyuz capsule . The craft carrying South Korea 's first astronaut landed in northern Kazakhstan on Saturday , 260 miles ( 418 kilometers ) off its mark , they said . Mission Control spokesman Valery Lyndin said the condition of the crew -- South Korean bioengineer Yi So-yeon , American astronaut Peggy Whitson and Russian flight engineer Yuri Malenchenko -- was satisfactory , though the three had been subjected to severe G-forces during the re-entry . Search helicopters took 25 minutes to find the capsule and determine that the crew was unharmed . Officials said the craft followed a very steep trajectory that subjects the crew to gravitational forces of up to 10 times those on Earth . Interfax reported that the spacecraft 's landing was rough . This is not the first time a spacecraft veered from its planned trajectory during landing . In October , the Soyuz capsule landed 70 kilometers from the planned area because of a damaged control cable . The capsule was carrying two Russian cosmonauts and the first Malaysian astronaut .
