Suspended Animation Hive Cells

If you are planning a deep space inter-galactic colonization mission, you'll probably need to place most of your foul alien larval horde in suspended animation until you are ready to unleash them on whichever unsuspecting corner of the universe you plan to over run. These hibernation cells are specially engineered for conservation of heat and energy - in field tests larvae survived for up to 6.2 aeons. Just hope that while hibernating there arent any evil onboard computers that let the life support systems go idle.
