Mission to Mars

quote [ "During one week, the most metabolically active male burned an average of 3,450 calories per day, while the least metabolically active female expended 1,475 calories per day. It was rare for a woman on crew to burn 2,000 calories in a day and common for male crew members to exceed 3,000." ]

If they want lighter, why can't they use a skeleton crew?

How much metabolic activity do the legs account for? You don't need those in space.

Legs account for 40% of body mass. I would estimate that person could reduce their body-mass by about 30% by removing both legs above the knee and replacing them with microprocessor controlled prosthesis. The heart can also be replaced in order to reduced body tissue by about a half pound. I am sure there are other unnecessary organs such as genitalia, external ears and parts of the brain that can be removed in order to bring the weight down on our would be astronaut.

NASA scientists are planning on an all vegan Mars crew as being the most sustainably efficient, trying to figure which garden as best to grow, vegan sushi and pizza, etc.
