Scientists have developed algorithms to calculate how much and what kind of food to deliver to the orbiting laboratory – everything from appetizers like freeze-dried shrimp to basics like powdered coffee, salt, pepper-oil, and water – on resupply missions every three or four months. They have also designed processes for preparing food that can be stored without spoiling for extended periods.
How would you resupply a human mission to Mars? Or, if a resupply isn’t feasible, what then?
