We've discussed the various hazards and risks in a journey to Mars and how to address them. We've also discussed a super-heavy lift rocket design that might be used for this mission. Up next is the transit habitat, in as much detail as I can muster. The post after this will explore the other parts of a complete transportation system; this one is only concerned with the passenger transport. One thing I didn't address in part 2 was why the vessel provides the entire food supply for passengers rather than using some stored food. After all, ECLSS-style supplies for a trip to Mars are only about 1.3 tons per person while a complete food supply takes around 3 tons of equipment per person and a whole lot more power. The reason is safety. If the vessel arrives at Mars only to find that all the landers have been destroyed then the passengers can wait in orbit until the next return window (or as long as necessary) and get back to Earth safely. At any rate, here are the concise results:Habitat Module (2 per vessel)HeightVolume, m³CrewMass, t(dry)tons per6 meters 8,380 97103459210.668 meters 11,140 13113017949.9312 meters 16,660 196181811809.28Vehicle Configurations - Chemical Configuration ...
