Re: manned Mission to Mars discussion

I can see the logic in sending a mission to Phobos as a stepping stone. It's got a lower gravitational field strength than Mars, so the required delta-V would be a lot lower. Also, if it's as pourous as it's been theorised, it perhaps wouldn't be out of the question to expand the base underground, since there's a chance it won't take much effort to remove the material (which in itself could be repurposed for manufacturing) to go underground, and the base can benefit from additional 'shielding' from radiation by living subsurface.
