The European Space Agency is currently exploring human hibernation as a means of addressing the problem of sending humans into deep space. A recent study conducted by the agency determined that putting people to sleep for long voyages would save money, provide health benefits, and allow for more efficient space ship designs.

It’ll take about seven months, under the right conditions, for humans to get to Mars. Elon Musk has a plan to get us there, NASA’s all in, and the ESA is exploring its options. There’s just one big problem: it might be a suicide mission.
