In my 3e hard-science TL9 'New Attica' setting, a potential plot point involves the main characters deciding to escape the coming MAD-level war between the orbitals and Earth, and scooting off to the asteroids to set up a self-sufficient little colony for themselves. I'm currently fiddling with potential ship designs; and I'm using the boardgame "High Frontier" as part of the background reference material for available technology. Using that system (which has a resolution of 40 tons), the current design is:
Rocket: Salt-water Zubrin and radiators. Thrust 8600 kN (~1-1.3 gravities), Isp 8ksec. 160 tons Fuel: 160 tons delta-vee: 16 km/sec (~10 mps) Active/awake crew and life-support: ~20 people, 120 tons Main Cargo: Robotic prospectors, smaller vehicles, mining gear, factory gear, generator, reactor, radiator: 200 tons Second cargo: Colonization gear & frozen colonists: 200 tons Dry mass: 680 tons Fueled mass: 840 tons Trying to convert that to GURPS using Spaceships, the closest approximation I've been able to get is: TL9, Exposed Radiators SM+8, unstreamlined: 1000 tons 8 Cargo holds: 400 tons capacity 1 Control room: $2M 1 Engine room: $.3M 4 Fuel tanks: $1.2M 3 Habitats: bunkrooms: $3M 1 Habitat: 6 specialized rooms: $1M 1 Open Space (food production): $.1M 1 Reaction engine, fission, Nuclear saltwater: $5M Spin Gravity: $.1M Fuel, 200 tons: $20M Total cost for 1-way trip: $31.7M (plus cost of colonization gear) Does that look reasonably sane to you? Do you see any places for obvious improvement?
