HEY!! I didn't post that mars trip crap! [edit]Oh, you already edited it. [/edit] They managed 3 HOURS with the dogs--that's a far cry from even 1 day, let alone 5 days, let ALONE multiple 5 day periods. They are obviously using the low temp to slow down the metabolic processes without actually stopping them--without actually killing the cells. So that what little oxygen the individual cells can store goes a long way--like 3 hours long way. Not 5 days worth.
