Emptying The Space Station of Humans?

Space station could be at risk if crews are forced to leave temporarily, USA Today
“NASA International Space Station Program Manager Mike Suffred says evacuation is a distinct possibility in mid-November if Russian Soyuz rockets are not flying, writes Florida Today’s Todd Halvorson. Past NASA risk assessment shows a one in 10 chance of losing the station within six months if there is no crew aboard to handle critical system failures. That soars to a 50% proability if it remains crewless for a year, the newspaper says.”

“It’s not a trivial thing,” Suffredini said. “If you look at…risk assessments, some of the numbers are not insignificant. There is a greater risk of losing the ISS when it is unmanned than if it were manned. That’s why, when we made our decision after the Columbia accident to keep the station manned, that is exactly why, because the risk increase is not insignificant.”
