I never quite understood how the Dragon -- or even NASA's Orion -- could possibly go to Mars.
It seems to me that any Mars cruise vehicle would need to be much larger -- giving the astronauts some room to stretch and exercise. Such a Mars
cruise vehicle would be assembled in orbit -- like a much smaller version of the space station.
I can see a Dragon capsule or and Orion capsule being part of
the Mars cruise vehicle assembly (maybe to ferry the crew up to the cruise
vehicle in Earth orbit and back to earth again once the mission is completed), but I can't see how JUST a dragon would be large enough to do that
I understand that the mission you posted being promoted by Dennis Tito is only a fly-by of Mars (that proposed mission will go to mars, but just whip
around the planet once, then immediately return to Earth), but even that mission requires almost months to get there and 9 months to get back.
That's a lot of time in a Dragon capsule -- even if it was modified to have slightly more room.
That's especially true of Tito's proposal, because those astronauts would never get out of the capsule to "stretch their legs" -- they would be in
it for the entire 16+ month duration of the mission. Maybe with his planned crew of just two people, the Dragon could be configured to give them what
they need, but I would like to see more information on what Tito and SpaceX envisions this Mars Dragon to look like.
