Hibernate to Mars: The Quest for Synthetic Torpor

Researchers are pursuing synthetic torpor—a hibernation-like state in humans—to cut metabolism, reduce radiation risks, and lessen food/water needs for long-duration space missions to Mars; while noninvasive triggers and early trials show promise, safely waking travelers remains a major hurdle, and initial practical applications are likely medical (e.g., organ preservation) before spaceflight, with timelines ranging from years to decades.
