The autodoc can put a patient into a statis state which is explained to be equivalent to hibernation. The name difference is why they didn't find it before. However, only one of the two conscious passengers could use this device to survive to see Homestead 2.

She thought external access was required for operation.
I thought transfer to an equivalent long term storage device was impossible and it was a singular piece of equipment.
While discussing it, we realized such a transfer could be necessary but require manual operation.
