The three members of the Expedition 9 crew arrive on the International Space Station, and the station promptly loses one of its three gyroscopes, which keep the station aligned in orbit. According to NASA, the station can remain stable with only two of the gyroscopes operating, and even if a second one should fail, the thrusters of the newly-arrived Soyuz capsule can keep it aligned. Departing in their Soyuz vehicle will be Expedition 8 crewmembers Michael Foale and Alexander Kaleri, along with ESA astronaut Andrè Kuipers, who arrived with the Expedition 9 crew to perform a week’s worth of experiments. Manning the station for the next six months will be Commander Gennady Padalka and Flight Engineer Mike Fincke.
