(6) BA-330 = (3) BA-330 Stacks
• (3) $400M = $1,200M
• (6) 25 mT = 150 mT
• (6) 330 m3 = 1,980 m3
• (6) 6 Crew = 36 Crew
(3) PB/DN = (1) PB/DN Stack
• (1) $375M
• (3) 17 mT = 51 mT
Adding everything up we get:
• Total Cost: $5,325M
• Total Weight: 501 mT
• Total Volume: 8,280 m3
• Total Crew: 84 Astronauts
Notice that our volume is close to the 8,300 cubic
meters advertised in the Hercules image.
Conclusion
Currently, the International Space Station (I.S.S.) is
orbiting the Earth, but will eventually be retired. There
really is no comparison, however, in their home and
ours:
As you can see from the poster, we’ll need three BA2100s, six BA-330s, and three PB/DNs to complete the
design. We can therefore calculate how many “stacks”
we’ll need:
(3) BA-2100 = (3) BA-2100 Stacks
• (3) $1,250M = $3,750M
• (3) 100 mT = 300 mT
• (3) 2,100 m3 = 6,300 m3
• (3) 16 Crew = 48 Crew
