NASA's Plans To Build A Human Settlement on The Moon (discovermagazine.com)

Nine private spaceflight companies are bidding on contracts to deliver robotic NASA payloads to the moon -- and Thursday NASA said they'd like them to start flying "this calendar year."

Discover magazine reports NASA envisions this "as the first step toward returning to the moon, this time for good." The first tasks will be to practice launching and landing on the moon, as well as answering questions about its surface... They will test habitation for future crewed missions. They'll prove that they can collect materials from the lunar surface and return them to space or Earth. And they'll establish communication networks between robots on the moon's surface, way stations in lunar orbit, and mission control on Earth.
But NASA also wants to deploy demo technology that can mine the moon's resources "to pave the way for human settlement," Space.com reports: The main lunar resource to be exploited, at least initially, is water. The lunar surface has lots of this stuff, locked up as ice on the permanently shadowed floors of polar craters. This water will aid lunar settlement and further exploration, and not just by slaking astronauts' thirst, NASA officials say. Water can also be split into its constituent hydrogen and oxygen, the chief components of rocket fuel.

The Commercial Lunar Payload Services program is just part of NASA's broad moon-exploration plan, which prioritizes an open architecture that encourages cooperation with many commercial and international partners. (Indeed, NASA wants to be the commercial landers' first, but not only, customer.) One of the most critical pieces of this plan is a small space station, called the Gateway, which NASA aims to start building in lunar orbit in 2022. Gateway will be a hub for many kinds of lunar exploration, including sorties to the surface by landers both crewed and uncrewed.

If everything goes according to plan, NASA astronauts will take their first such sortie in 2028 -- 56 years after Apollo 17 crewmembers left the last boot prints on the lunar surface

      Right, but energy is easier to understand than "delta-V", for someone who thinks you can push things into the Sun.

      Once you're out of propellant, you can't apply even a small amount of force.

      Space travel is all about delta-v. The total change in velocity you can achieve with a rocket craft is determined by the exhaust velocity and the fraction of its initial mass devoted to propellant. Higher delta-v's require higher propellant fractions or higher exhaust velocities, and there's limits to both.

      For an object sharing Earth's orbit around the sun (like one that has just barely escaped Earth), hitting the sun takes a delta-v of about 30 km/s, because you have to cancel out the object's orbital motion. Escaping it takes only 12 km/s because you can just add to it instead.

    Not only will we get practice in living on another planet, and a chance to build some lunar-based space industry, but having a working colony of humans off-world is good against the possibility of some major catastrophe on Earth.

      Sure, but that's going to be true no matter what. As human beings who evolved very specifically to live on Earth, we are 100% dependent on Earth's biosphere, and barring some unforeseen technological breakthroughs (nanotechnology, maybe?), we will be for a very long time.

      We can't even construct a viable self-sustaining biosphere-replacement here on Earth, never mind trying to make one work inside the additional constraints imposed by space travel.

  5. The Moon is an Expense -- Mars is an Investment by Slicker · · Score: 5, Interesting

    Sure, let the national space agencies build settlements on the Moon. There is no commercial viability in those places. Commercial organizations will go where the money is -- deep space asteroids and Mars.

    The Moon will be very costly to maintain humans on. The "plentiful" water on the Moon is in very relative terms. It's likely to take days of work for a glass full enough to drink. And the extremely abrasive regolith and pitch-black-only shadows plus zero protection for radiation is all going to add risks and work.

    Still, I do think some inflatable habitats on the Moon, once buried in regolith will have their uses, in terms of science and long term commercial uses.

    On Mars, north and south of the equator hold hundreds of large, fresh water glaciers more than 2 km deep. The soil elsewhere holds about two liters of water per square meter of regolith. And the regolith is very soft and less abrasive than soil on Earth. Metals in Martian rock are all the same as Earth except about twice as much, in proportion. Martian Basal is near ore-grade for iron. Waving a magnet over the surface is all you need to do to collect very rich iron ore. And the atmosphere and gravity make it easy to launch this stuff into orbit on single-stage rockets.

    Although the Moon is closer and therefore easier to send help from Earth, it's also far more likely that help will be needed. It won't take much to become self-sufficient on Mars.

    However -- I would prioritize exploration of lunar lava tubes. It's reasonable to think that larger concentrations of water ice might exist in them. If that's the case then settlements in lava tubes on the Moon could be very profitable.

      [citation needed]. Your claims are at odds with this NASA study which suggests that "thermal extraction of the in-situ water [in lunar regolith] is an attractive means of satisfying water requirements for a lunar mission".

      On Mars, north and south of the equator hold hundreds of large, fresh water glaciers more than 2 km deep.

      If by "fresh water" you mean "the exact opposite of fresh water" -- it is my understanding that Martian water is more like a brine. Where are you seeing reports of large deposits of "fresh water" on Mars?

      And the atmosphere and gravity make it easy to launch this stuff into orbit on single-stage rockets.

      Mars' atmosphere is thicker than the moon's, and Mars' gravity is stronger than the moon's. You're wrong on both counts here, if you're still comparing Mars with the moon.

      There's also the fact that a fuel depot at Earth-Moon L1 would be a lot more useful than one near Mars, since most missions start here.
