(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 www.RocketSTEM.org WEIGHT 501 mT LUB
