Hibernating in Space: A Possibility?

Scientists believe that human hibernation across the vastness of space could one day be possible, which would be a boon for space exploration. Hibernating astronauts wouldn't eat or drink much, and would consume minimal oxygen, saving mission controllers a huge amount of money. There would also be health benefits to hibernation, as it could protect against muscle wastage and bone density loss. However, it's vital that we gain more of an understanding of how the body and brain would initiate the process in the first place.
