Humans Settling on the Moon: What Do You Think?

[15characters]

We can eat it, but we don't have to.
Assume a spherical cow in a vacuum... the latter is easy to access on the moon.

a spherical cow? how does that work then?

 

[mfb]

Oh, that is very simple.

;)

Remember, homo sapiens is a meat eating species,

We can eat it, but we don't have to.

Well, yeah, but only if there is pizza available (and only if you don't count pepperoni as meat)

 

[newjerseyrunner]

We can also grow meat now, it doesn't have to come from an actual animal.

"a cow on the moon"

would be very expensive and probably dangerous to convert that to this:

One meteor, a micrometeorite, or some x-ray blasts and a couple cosmic rays from the galaxy later and everyone's packing up and going back to Earth.

 

[mfb]

The ISS survived 15 years of micrometeorites already. A moon base would use shielding against cosmic rays which doubles as micrometeorite shielding. Sure, a big impact could still ruin the base, but that can happen with towns on Earth as well.

Helium is one pretty major resource that's running out on Earth but pretty abundant on the moon. There are lots of others:

But I'm pretty sure we need an alternative to rockets for this to become economical.

Also, let me just say that I fully support a vanity project like building a base on the moon. There are far worse things we are spending that kind of money on (such as war). If we could divert some money to do something like that, it'd be pretty amazing.

What's wrong with the old H.G. Wells idea of shooting things for a cannon? If the cannon is a magnetic rail cannon.

Running out of room or resources will never be a reason to settle on the moon or anywhere else outside of the earth. There just won't be any way to transport enough people to make any difference. The only reason that will ever make sense is adventure.

It's already been said that space exploration should be our ultimate goal because we understand how limited the life of our home planet is.

 

[Elite Jacob]

Colonizing a celestial body, like exploring space, is an aspect of our survival as a living organism. We understand the life cycle of stars, and we know that our star will eventually die. Our common goal must be to gain the ability to at some point leave and colonize other star systems with lifespans that will out live our current one. It is my belief that projects that are aimed at making structures that will allow human life to survive in extreme conditions will lead to more understanding of what will be required for other planets. For example a sustainable living structure at the deepest point of Earth's oceans could be a precursor to colonization of a planet with subsurface oceans. If we could make a place that could allow life to survive on the other side of the Earth's crust we would have no trouble colonizing other planets. The required adaptations to the environment would no doubt be extreme, considering with current knowledge and technology oxygen needs to be mixed with helium to be breathable during deep sea expeditions. There may also be the sad but simple truth; that we as terrestrial life forms lack the ability to live anywhere but our place of birth. I'm usually wrong though, just ask Evo.

The problems with this approach are legion and have been discussed here several times. I suggest a forum search.

Man does enjoy exploring, as we did with this planet, but I really don't believe that man will ever colonize other planets in the time our species has left on this one. I think it wise to embrace all the lore and religions which place the heavens above us as out of our reach and not our realm. Better to stay mindful of our own place on Earth, lest we lose that. The young man's desire to seek and explore the cosmos is very natural and yields many interesting results, but beyond discussing colonization as a mental exercise, it simply will never happen.

The main problem will be the low gravity. Astronauts/cosmonauts in 0 g for long periods experience bone mass loss, blood loss, and muscle atrophy. A permanent colony would either have to be centrifuged or force everyone to work out in a centrifuge fairly often.

But how bad are those health problems in 1/6th G and not zero G?

 

[rootone]

I would imagine that loss of bone and similar would still be a problem, just that it would be somewhat less aggressive and so would take longer for it to get to the point of becoming disabling.

 

[mfb]

Testing that would be one of the scientific goals of a manned base on moon. It is probably a reasonable guess that 1/6 g is better than zero g, so one year should be possible, maybe more. 437 days is the record in zero-g, and we'll have 6 spaceflights of at least one year duration next March.

A staged approach to a Mars landing and then base, with an ion drive to reduce transit time, would make more sense than a lunar settlement. Send an unmanned ascent vehicle so Mars-nauts can get from Mars to orbit, and a habitat with laboratory. Both would start processing Martian atmosphere to make oxygen, nitrogen, hydrogen, water, single-malt Scotch, all ready for the new Martians. The habitat would stay, even if the first Mars-nauts returned to earth. Oh, take some 3D printers, along with a world library of literature, music, science. Buzz Aldrin outlined a staged approach a few years ago, except he's a whiskey man.
