If I don't worry about morale, would daily, average sized meals from the following be sufficient to stay alive for three years in space? I'm assuming only water is recovered from waste.

Assume enough electricity for cooking, zero gee pots and pans, ISS type kitchen equipment, spare parts for waste treatment hardware, and an routine waste dumps to space as needed.

  • Dried beans
  • Rice
  • Oats
  • Dried meat, fish, squid, etc. (if one partakes)
  • Olive oil
  • Salt
  • Vitamins (+omega 3, 6)
  • Electrolytes
  • Powdered/dried seasonings
  • Water

edit: For this mission, dried bulk items were chosen because they can potentially tolerate larger excursions in temperature for long periods of time. There are no freezers or refrigerators, and the mission may go inside Earth's orbit as well as way beyond, so keeping the food "outside" in the cold was not an option on his budget flight.

    $\begingroup$ This diet is likely calcium deficient, at least. $\endgroup$ – called2voyage May 15 '17 at 15:02

    $\begingroup$ Food like this would be extraordinarily difficult to cook properly in space. There really isn't any facility on ISS that can boil water in a cooking fashion (boiling in a pot is heavily reliant on gravity-driven convection), which would make beans and oats tricky. Powdered anything is an absolute no-go in space -- once spilled, it's almost impossible to clean up. $\endgroup$ – Tristan May 15 '17 at 15:06
  • $\begingroup$ You are right. Calcium is not part of a typical vitamin pill, and the term electrolyte might not include nutritional quantities of chelated calcium. $\endgroup$ – uhoh May 15 '17 at 15:06

    $\begingroup$ Infuse your seasonings in fluid to eliminate the powder problem. On shuttle: "Polyethylene dropper bottles contain bulk supplies of liquid pepper and liquid salt. The pepper is suspended in oil and the salt is dissolved in water. " $\endgroup$ – Organic Marble May 15 '17 at 15:28

    $\begingroup$ Some additional protein I think. Beans contain some protein and rice too. But an astronaut in space does not need so much carbohydrates to get enough protein from beans and rice only. Soybeans have more protein than usual dried beans. $\endgroup$ – Uwe May 15 '17 at 16:38
