Once the technology is ready to reach and set up a base in Mars (perhaps 10 years if SpaceX expectations come true) could it be possible to build a route among the asteroids to reach Jupiter's moons?
The problem of the time of the travel would be more or less the same if you would have bases in the following places, and if you start the travel when the planets/asteroids are closer,
- Earth - Mars 0,52 AU
- Mars - Vesta 0,63 AU
- Vesta - Sylvia 0,64 AU
- Sylvia - 588 Achilles 0,67 AU
- 588 Achiles - Jupiter 0,57 AU
But how about the problems of setting permanent bases in those asteroids, even when some are large ones of almost of the size of a dwarf planet, would it be feasible? Setting up a base in Mars it has to be easier. I suppose they plan to obtain water from Mars, may be they would find a way to obtain Oxigen from the CO2 in the atmosphere, also I suppose Mars is warmer than those asteroids and have more protection (even though a tiny not enough protection) from radiation than atmosphereless asteroids, and how about energy supply, if the way they plan to obtain energy in Mars is somehow related with the sun (solar energy), that has to be harder when you are far away.
Could a route among the asteroids be built to reach Jupiter's moons once the technology to reach and set up a base in Mars is ready?
