NASA is working on synthetic torpor (quasi-hibernation) to make Mars missions survivable. The math is brutal: 6-9 months one way, years total mission time, massive payload penalties for life support.
Recent human trials at U Pitt (funded via TRISH) used dexmedetomidine to drop metabolic rate ~20% and slightly lower core temp. Subjects stay semi-conscious—can wake to eat/drink/piss—no full sedation or ventilator needed. This is the first real-world proof of concept for reversible metabolic suppression in humans.
NASA's STASH project (2024 NIAC selection) will fly a rodent torpor lab to ISS to study how microgravity affects hibernation physiology, specifically bone/muscle preservation. Arctic ground squirrels naturally hibernate without losing muscle mass—reverse-engineering that could solve the atrophy problem astronauts face.
Earlier modeling showed torpor habitats could slash spacecraft mass and consumables by huge margins. The endgame: pharmacological + thermal techniques to put crews in low-power mode for months, cutting radiation exposure, psychological load, and supply chain complexity.
Still years from operational use, but the biology checks out and the engineering incentives are massive. If it works, deep space suddenly gets a lot more feasible.
