Sorry, but ANY mission that requires 5 co-ordinated launches is a loser
Both the Ares and Jupiter profiles for a Mars mission require 5 launches.
Unless you have a permanent full-time large-capacity space station in equatorial orbit (as a docking/refuelling/reconfiguration station) then you're smoking dope...
Th chance of partial mission failure is around the 20% level, based on past experience, so requiring 5 launches GUARANTEES a failure.
So let's look at the REAL statistical plan, with backups...
It might actually be best to build a Saturn V+ class launcher. It either works, or it doesn't...
Let's see some PROPER analysis!
