NASA Funding Deep-Sleep Studies for Mars Transit

Spaceworks Engineering is studying a concept that would put astronauts into a deep sleep (hibernation or torpor) for long-duration space missions.

John Bradford of Spaceworks says medical progress is advancing our ability to induce deep sleep states with significantly reduced metabolic rates for humans over extended periods of time. Because astronauts would not be awake and moving around, the habitat volume needed for long missions could be significantly reduced. The slower metabolic rate would reduce life-support requirements as well.

Spaceworks has received a $100,000 Phase I award from the NASA Institute of Advanced Concepts to design a torpor-inducing Mars transfer habitat and assess its effect on Mars exploration architectures.

Spaceworks envisions a small, pressurized module docked to a central node/airlock, permitting direct access to the Mars ascent/descent vehicle and Earth entry capsule by the crew. Spaceworks believes the torpor approach can reduce the habitat size to 20 cubic meters and 5-7 metric tons (for a crew of 4-6), compared to 200 cubic meters and 20-50 metric tons for traditionally designs.
