:: 24.09.2010Statement for mass media by Roscosmos Head Anatoly Perminov “Departure and landing operations of the Soyuz TMA-18 crew vehicle scheduled for this morning are postponed for tomorrow due to technical reasons.Preliminary analysis shows that the onboard computer system acquires false Soyuz/ISS interface leak signal. On the other hand, leak check operations confirm pressurized status of the interface. The departure could have taken place during the 3rd orbit today, however the State Board decided to postpone Soyuz departure and landing for tomorrow in order for the experts to find out about the reason for the glitch and to support the dynamical operations properly.MCC, Rosaeronavigation personnel begin operations in order to support descent and landing on Sept. 25 in a back-up spot.The Soyuz crew – Alexander Skvortsov, Mikhail Kornienko and Tracy Caldwell Dyson – were ordered by the ground control to return back to the station. Health status of the crew is fine”. Roscosmos PAOMCC-M, Korolev
