How much food to take to mars using this as a metric? That 41,600 calories in 1.59 cubic feet would be 923,520 in one cubic meter which is about a year of calories (massing 312 kg not counting water.) Include the high calorie foods in the title for better caloric density.
Water can be recycled at better than 90% efficiency. You need about 2200 kg of water per year per person. With recycling 300 liters should be enough, but to be safe 688 liters giving us one ton total of water and food per person for a year (for an 8 month trip.)
That's about a ton less than I've been using in my calculations. Mars should be closer than I've been saying. It's really just a matter of when somebody picks up the tab which is really only about 1% the cost others will scare us with. You see how frustrating it is not to be a billionaire? You could even have my coffee ration!
