A somewhat costly state-of-the-art manned outpost of considerable size should be established on the Moon. Not only should it be designed for scientific research, but also as a tourist destination. Money to support this endeavor would come from taxes private capital, and/or tourism.

Mars One will be second anyway. ;-) The whole story at: http://vodo.net/pioneerone Download for free the first 6 episodes, worth watching. If you enjoy contribute to cover production costs of next episodes. mic 2012/6/6 Daniel Rocha danieldi...@gmail.com: Realities shows are successful

I'm sorry, but as an engineer if you imagine that you can build a fusion powered spacecraft with an exhaust velocity of 7.5e6m/s and 40MW of engine power per kg of spacecraft (from rocket equation with 20% fuel use in 2 days at 1g thrust), when nobody can yet build a viable self sustaining fusion

I say, why waste time going to Mars, when you can shoot for the stars! We need to set our goals and/or expectations higher or farther actually. While it would be a very cool thing to have some fellow Humans residing on Mars, it's getting there in a vastly improved capacity that will enable

Sadly I do understand, I am just not blind to the implied engineering requirements. *40MW/kg !* The highest power to weight machines (outside of bombs) that humans have ever build were the space shuttle main engines, they did about 3MW/kg utilising a supply of LH2, the best possible coolant,

Like Friedwart Winterberg's Supermarx concept? http://nextbigfuture.com/2008/12/micro-fusion-for-space-propulsion-and.html I really like the concept, but there is still no way that it can achieve the power to weight required to give 1g at 7.5e6m/s Isp. Heat loads and driver power requirements

Realities shows are successful because the success of one relies on the humiliation and exclusion of other participants, like in the old Coliseum. That is not possible in this mission, though, unless you kill passengers, like in the old Coliseum. 2012/6/6 Patrick Ellul ellulpatr...@gmail.com
