A cross-section through the hibernation module showing the individual quarters that would double as hibernation pods during the cruise phase. The soft-shelled pods would have individual thermal controls and flexible insulation, with a fan to circulate air and control humidity to prevent condensation when the temperature is reduced during hibernation. The pods would also be well shielded against radiation. (1)private crew quarters, (8) life support system and stowage, (10) circulation space.
