Does torpor help or hurt with respect to the degeneration of the body in extended weightlessness?

This is a question we are attempting to address but it will be some time still before it can be answered fully. While there appear to be potential benefits with torpor, we are also considering different options enabled by the use of torpor for addressing common spaceflight physiological issues. For instance, with the crew in an unconscious state, we can induce artificial gravity at higher rotation rates and lower radii without concern for discomforting Coriolis effects and gravity-gradients. Similarly, to reduce muscle atrophy, we can routinely apply electrical neuromuscular stimulation to the crew – something that would not be possible with an active crew. They may actually arrive at Mars in better physical shape than when they left Earth!
