Self-Sufficient Lunar Habitat Designed

An anonymous reader writes "Cosmos Magazine reports on a design for a lunar habitat that is 90 to 95 percent self-sufficient. The proposed habitat uses a closed-loop life support system that recycles and regenerates air, water, and food, reducing the need for costly supply trips. The north pole of the moon is chosen as a location because of its access to sunlight and useful resources. About 11 astronauts could live and work in the habitat for 2 to 3 years. The project would also help the environment on Earth with recycling and other sustainable practices." The designers say it could be 20 to 30 years before such a habitat could be up and running on the moon.

Unlike the later Biosphere 2 (the greenhouse-like one in Arizona you're probably thinking of) this was much smaller, indoors (lighting for the plants was artificial -- and the whole thing had an external water cooling system to remove excess heat) and focussed mainly on recycling air and water. They did grow some of their own food (algae and wheat, yum), but also had regular food inputs from outside. Partly this last was due to Russian regulations governing experiments involving humans, by law they were required to be supplied with a regular ration of meat.

      Anyway, the experiments were successful within the design parameters. (I had a chance to visit the facility a few months after Krasnoyarsk was opened to westerners, I still have a sample of the wheat grown within it.)

      Biosphere 2 was more ambitious, aiming for 100% closed and no artificial lighting for the plants, for a two-year duration. They didn't make it, due to some surprises in the atmospheric chemistry (and things like interaction with the still-setting concrete), and the thing was way more than would be set up on the Moon anytime soon anyway. Bios-3 was much closer to a Lunar habitat prototype, and proved to be workable. (Yes, there'd still be some supply issues -- it will be a long time before anywhere off-Earth is totally self-sufficient, you need huge buffers and/or very good monitoring to make up for random events in the ecosystem.

Harry Jones, Alan Drysdale, and other big wig life support analysts aren't convinced complicated regenerative systems, especially crops, will actually make for a cheaper lunar or orbital system.

      Actually...

      The moon is a really good place to settle. There is a gravity well; but it's such a small one that you get the convenience without the penalty. It's nice having things fall down; it makes all kinds of useful resources --- rock, ice, metal --- easily accessible, and you don't have to worry about stuff drifting off. Not to mention that all the production techniques we know about involve gravity at some point. It's also nice having such a ludicrously small gravity well that you can get into orbit with something the size of an Apollo lander rather than a Saturn V. It's an excellent compromise.

      It's also really nice being three days travel away from home. In the event of an emergency, it's entirely feasible to sprint home directly from the lunar surface. You can't do that from an asteroid, where you've travelled for months just to get there.

      You're right in that asteroids are excellent places for robotic mining... unfortunately, we don't know how to do that yet. The state of the art just isn't there. Given that we still don't have the technology to travel anywhere in other than a minimum-energy transfer orbit taken months, and that mission planners have to plot crazy momentum-stealing flybys of practically every inner planet in order to minimise delta-V, launching experimental robot refineries from the surface of the Earth just isn't going to happen. Wait another twenty years and build 'em on the Moon instead. You'll have the knowledge, the personnel, the materials, and you won't have to lift them out of Earth's huge gravity well.
