> On the problem of weight needed to sustain a crew They say 4 people need 11 tons of food for a 1100 day mission. That’s 2.5 kg per person per day. It looks like this includes water. Water can (and is) recycled in space missions. A lot of food in space is dehydrated (you can buy astronaut ice cream at any science museum, and it’s not that bad). You may get away with only 0.5 kg of solid food per person per day. If they did the same type of generous estimates elsewhere, then maybe 100 tons would suffice, instead of 300. And 100 tons is how much the Statship is supposed to be able to carry. |
