Re: Could we put tourists on the moon for $20M apeice?

You need to mine the water first. At the stage in which you had say had a total of 1000 tons of water mined, this might not be such a funny idea.

If you wanted to do it now without any development, the ticket price would be about 10 times your number- 200 million each way. And at 200 million it wouldn't really pay the development cost- it would be similar to 20 million for tourist to ISS. Meaning no one currently, can develop any system that gets 2 passengers per year to ISS and make a profit- unless this system also had other revenue sources. As far as marginal costs goes, the Russians are making a profit at the 20 million ticket price to ISS.
