You may have heard news that NASA is considering worse case scenarios to de-crew the International Space Station (ISS) in November. This is due to the failure of the first ever Russian re-supply module launch which occurred on August 24th. The third stage engine suffered a failure and subsequently crashed.
Russian space agency officials think that a gas generator failed in the 3rd stage engine and if verified it would go a long way in getting the Progress resupply modules flying again. The crew has plenty of supplies for now. The de-crewing of ISS would be to insure the safety of the crew as the same engines are used on Progress as the manned Soyuz rockets. Without the Space Shuttle, Soyuz is the only manned access platform available.
