Alan Wasser and I think that space property rights are the main thing holding back development of the Moon. Dwayne Day says (last paragraph) that launch cost is the main thing that is holding us back. I don’t think that was true when Saturn Vs were in production.
While high launch costs as a barrier may be temporarily true today, I think that cheap access would be developed to the Moon if it could be claimed legally and the property rights enforced (and may anyway if Elon Musk is to be believed).
The Saturn V Wikipedia entry cites these cost numbers. They add up to $6.42B peaking in 1966-7. The launch cost estimate in Astronautix of $431M is just $6.42B/15. While they list a bunch of R&D contracts that precede the Saturn V line item, they were sunk costs at the time of Saturn V deployment. If someone has a better number please comment. A summary of Schmitt comes up with $3B per launch including $500M in capital costs. Those costs should be written off as sunk (i.e., a company that incurred them would declare bankruptcy and emerge with no debt). The $2.5B remaining is the 2005 price of $431M in 1967 dollars.
Am I missing something? Is pad construction, tooling, design and so on not included in the original $6.4 billion? If non-recurring costs made up a good fraction, then it’s a way overestimate.
Griffin puts the marginal cost at $100M in 1970 dollars or about $500M today. That would give us $2000/lb to LEO. If we had continued to put $15B/year in current dollars into Lunar development, that would be about 87.5 million pounds to LEO in the last 35 years if 1/3 of the money was spent on launches or over 15 million pounds to the Moon assuming no improvement over 1960s technology (and to be fair no bureaucratic price inflation beyond the consumer price index). That is about 75 international space stations worth of mass.
No, I think the main reason we abandoned the Moon was lack of national will, not price. The price point for colonization can be achieved if the national (or subnational or even rich guy) will comes back. My proposition is that Lunar property rights would be the impetus to set these wheels back in motion. I dare you to prove me wrong.
