Sarcophagus-class Cryopod

Cryopods are sealed containers designed to induce a frozen hybernative state in their occupants that can prevent them from aging, advancing in illness, or regaining consciousness. The interior benefits from a powerful life-support system that can sustain a sleeping occupant for hundreds of years, although some research suggests that if the cryopod is kept in the vacuum of space, it could last thousands of years. Occupants of cryopods can be revived either when a set period of time has elapse, or if the process is initiated from the control panel. For safety reasons, it is recommended not to interrupt this process until it is complete, which itself can take up to 24 hours, after which the occupant may still experience grogginess, disorientation, and temporary blindness for several hours after becoming conscious. It is also risky to use cryostasis frequently or for short periods of time, since the freezing and revival process poses some risk of vascular problems, neurological impairment, and tissue damage. For these reasons, it is best to wait at least a week before re-entering cryostasis.
