+ | === Cargo === | ||
+ | |||
+ | The first is cargo space, which when full will count as 10,000kg per // | ||
+ | |||
+ | Each dt of cargo being carried therefore counts as +10dt to the ship's actual mass. | ||
+ | |||
+ | === Fuel === | ||
+ | |||
+ | The second is fuel, which is often a liquid (sometimes solid) which completely fills the fuel tank with no space left over. Like cargo, fuel also has a density and so a full fuel tank increases the mass of the ship. Water counts as +14 per dt (14m³ of water has a mass of 14 tonnes, by definition), | ||
+ | |||
+ | === Supplies === | ||
+ | |||
+ | Crew need supplies, which counts as cargo. 1dt of supplies has a mass of 5,000kg, and will last 1 crew member 1,000 days. This includes food, water and other necessities. It is assumed water is recycled as much as possible, but ' | ||

+ | === Crew Quarters === | ||
+ | |||
+ | How much space crew need depends on the duration of the flight. | ||
+ | |||
+ | * Hours: 0.5dt | ||
+ | * Days: 2dt | ||
+ | * Weeks: 5dt | ||
+ | * Months: 15dt | ||
+ | |||
+ | Cramped quarters are about half this. Luxurious can be from twice to five times this. | ||
