That will not be chemical rockets for reasons I explained related to the specific impulse limits. Hydrogen being very light and releasing a great deal of energy when oxidized is hard to beat - why it was used.... I know, which is why I said until the tech improves. As in, a new method of getting into space that is cheap and can be more open to the common man.
No even extracting from the oceans is much cheaper than using moon resources. Material resources do NOT get scarce - they remain on Earth. It only gets more costly as the natural concentration is reduced. Given the fact that the moon is smaller, has less internal radioactive heating and certainly less gravitational collapse heat when it formed, it is highly likely that the concentration of the "resources" there is much lower than on Earth. The moon has no volcanoes. - It is the internal heat that separates material into ore bodies. This alone, even neglecting the huge cost of going to get them and returning them to Earth, makes "moon resources" unattractive economically!...Although resources will probably become a better enterprise once the resources on Earth become scarce.
Now you are talking. Want to invest in my "pixy dust" plant ?...What about personal space vessels? Like cars, except they are space ships, that are mass produced and made affordable to the common man. There's a profit.
I have wasted 3 minutes or so trying to find an old thread thabout the three most important /interesting inventions yet to come (or something like that) One Of my three was a Moon Base. I went into some detail about how it would be. (Underground as the sun shines continuously for 14 earth day with no clouds) and how it would be powered - large rooling sun screen keeps solar heat form the cold patch of earth during the 14 days and then moves over to cover the Hot patchwhen14days of nite come to reflect the radiant heat back into the dirt. A heat engine with coils in these two patches to collect high temperature heat and dump waste heat will have high efficiency as the temperature difference is very large.Maybe they should focus on making a lasting base/enviroment bubble type structure on the moons surface before trying to launch off anywhere else. ...

To all posting nonsense about mining the moon for “resources,” I again ask you to:
Name even one item that is not available now on Earth for less than 1% of the cost of going to moon and returning it to earth.
You CAN NOT AS THERE IS NONE.
Not NASA's. It is a Chinese moon base.I think you wasted 6 minutes, and that is way too much. We already killed the argument for NASA's future.
I mentioned that in footnote of post 15 as follows:Helium-3
space is heaven.
You're assuming that
A) anti-gravity is possible and
B) it's a propulsion method.
Nope.I do not wish to get into any arguments. I only wish to get the information out there.
Reports are already out in the open, it is only up to you whether you choose to accept them.
This technology already exists and is operational on several aeronautical craft.
Indeed it is, let's not let them make it a place of war.space is heaven.
Again there is nothing on the moon that is not available on the Earth 100 times cheaper.
With all respect Billy, because I will not reject your viewpoint out of hand, could not the same be said about the colonisation of America?
