Is human hibernation for long-duration space travel possible?
Explores human hibernation for space travel and potential methods.
Human hibernation could allow astronauts to endure long space voyages by drastically slowing their metabolic rate, similar to concepts popularized in science fiction, like '2001: A Space Odyssey' and 'Alien.' Sandy Martin from the University of Colorado suggests the psychological and logistical benefits, such as reduced need for resources and radiation exposure.
Methods like medically-induced hypothermia, already practiced for severe medical conditions, might hold the key to human hibernation, despite its current short and mild use. Alternatively, scientists study animal torpor for its natural, efficient metabolic suppression, potentially unlocking genetic or biochemical pathways to mimic this in humans, addressing concerns about our physiological survival limits.
Despite potential advancements, challenges like monitoring hibernating crewmembers, emergency response, and AI reliance pose significant questions. Addressing these is crucial before real-world implementation, especially if human missions to Mars or beyond are forthcoming, warranting further research into hibernation solutions.
