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. ;-)

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,

That is a luxury you do not have
with fusion in an ultra-high Isp engine.
It is also a luxury you don't need.
The trick is to perform the reaction in space itself.

Like Friedwart Winterberg's Supermarx concept?

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

At least two differences.
1) There is no explosion, but rather a continuous burn.
2) There is only very minimal photon production (when
Funded by marketing it as one big reality show... Possible?? And would you
buy a one way ticket to Mars?

Hi,

I wrote to Elon Musk offering to help him build a fusion powered shuttle to get
us there in 2 days at 1 g with only 20% fuel mass.
No response.
Funded by marketing it as one big reality show... Possible?? And
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.
