Due to a crashed Russian Progress supply ship we are in danger of losing the ISS.

Earlier this month a supply ship to the ISS failed to reach orbit.  Russian technicians are working to solve the mystery of the crash.  Until then nothing is going to the station.

Thanks to the shuttering of the shuttle program Russia is the only way to get supplies to the station.  Not to mention the only way to get replacement crews to the station.

If the problems with the Russian rockets are not solved in time the station may have to be abandoned.  This greatly increases the risk of losing the ISS.
