Growing Plants on the Moon May Be Feasible

Smivs writes "European scientists say that growing plants on the moon should be possible. Scientists in the Netherlands believe growing plants on our sister satellite would be useful as a tool to learn how life adapts to lunar conditions. It would also aid in understanding the challenges that might be faced by manned bases. 'The new step, taken in the experiments reported at the EGU, is to remove the need for bringing nutrients and soil from Earth. A team led by Natasha Kozyrovska and Iryna Zaetz from the National Academy of Sciences in Kiev planted marigolds in crushed anorthosite, a type of rock found on Earth which is very similar to much of the lunar surface. In neat anorthosite, the plants fared very badly. But adding different types of bacteria made them thrive; the bacteria appeared to draw elements from the rock that the plants needed, such as potassium.'"

True, things like water changes become logistically harder as the tank sizes get to the enormous ranges, but you build around that.

You've got to watch a 5 gallon tank like a hawk for things like spikes in ammonia or shifts in pH. A 50 gallon tank is quite easy for a beginner to maintain, apart from having to lug buckets of water around. If you heater goes out, or worse if it get stuck on, you're fish are dead if you don't notice it right away. In a fifty gallon tank you've got some slack.

      The logical end goal of growing plants on the Moon would be to set up a system in which the plants, given a carefully controlled start, establish an environment that achieves equilibrium without putting more resources into it. Naturally, the larger the environment is, the easier it would be to do this. Once you have established how much space you need to reach a moderately stable equilibrium, let's say it's a thousand cubic meters, you can build larger examples that actually resist moving away from their equilibrium point.

      The thing about systems in equilibrium, as any chemical engineer will tell you, is that when you take something that is part of the equilibrium out, they respond by making more of it.

That just leaves cosmic radiation and constant temperature. These are not trivial problems. Cosmic radiation might not be too bad - the seeds that the Apollo astronauts took to the moon and brought back remained viable, and many living organisms have survived shuttle and space station missions for prolonged periods of time. You'd want something fairly hardy against radiation, due to the time factors involved, but it's possible that fairly minimal shielding would be sufficient. The temperature more complex, as a prohibition on repeat transports eliminates the carrying of fuel for generators to power temperature regulation systems. You'd want some way of capturing the heat from the "daytime" and then releasing it on an as-needed basis over a sufficient area that temperatures remain within acceptable limits. Since water is needed in the system anyway, using solar water heating (with solar-powered pumps) would seem to be an easy way to carry heat around. Spray the water into the air of the dome as a fine mist and you've a heat release mechanism (and artificial rainfall).

    Would this be enough to grow plants on the moon? The only way to find out would be to do the experiment, but as Biosphee 2 demonstrated, miscalculations are expensive and easy to make. (Biosphere 2 would have needed to be two to three times the size it was to have functioned as intended, due to uninvited insects getting in.) On Earth, the miscalculation was so expensive that nobody has tried repeating the experiment with recalculated dimensions. For the moon, where the cost of transport and construction would be tens of thousands that on Earth due to the high fuel costs and short mission times, you not only get just one shot at it, but you also have to make sure that one shot produces enormous value for money. Unless you know of a tree that produces pure platinum fruit, I don't see that being possible - at least, for now.

The US consumes 3.35TW, which over 8765.81277 hours a year * 3600 seconds an hour is 1.05715702 x 10^20 joules. Which is 1174.61891 times the 9 *10^16 joules you say it would produce.

      About 1.3KW falls on each square meter of the Moon about half the time, for 650KW:m^2. If the plants get only 5% efficiency by the time it's beamed to the Earth (Soviet tech for their energy space station was already 98% efficient between orbit and base station by 1990), that's still 32.5W:m^2. 3.35TW would take a Lunar area 321055.95m on a side, 0.0367977612% of the Lunar surface.

At $115 (the low end in the timeframe we're talking about), that's $8,819,937,903 but as it goes closer to $200 or more by the time we're actually using it as energy the way power arriving by laser would be usable. That's $15,339,022,440 of oil we wouldn't have to pay for, because we replaced it with a $1B investment on the Moon. That's over a 15x ROI.

      But of course your math isn't how we'd measure the operation. Because a Lunar solar base wouldn't deliver 90 petajoules and then quit. It would deliver energy in watts. So after that first 7.5 hours in which those 90Pj were generated at the scale you described, it would continue to pay off. As I noted, even just 5% efficiency means a 15x ROI. But the money isn't the limit. The real limit is the carbon, oxygen and water (H2O). Which is OK, because though the moon has hydrogen and oxygen, and would need most of the carbon making much of the plants' mass to be imported, the scale of the humans is pretty small compared to all these numbers we've been throwing around. And with new highly efficient PV at 45% (not the 5% I've used here), before we even make the huge R&D investment (of the kind at NASA that generations ago invented PV cells, fuel cells, and so many other techs we'd use), we're looking at well under 1/7 the scale of operation necessary to reap the vast benefits.

      My point has been to show that the Moon is a huge potential source of energy from the Sun, without many of the political, ecological and physical problems of tapping it here on Earth. It should be clear that there is that amount, and even if Lunar farming were all we were doing (independent of a PV operation), we could still be talking about energy export at those scales, because it's so energy productive.

    that soil here on Earth possesses. One very interesting finding in lunar dirt is the presence of
    structures called 'agglutinates'. They are essentially 'bonded' shards of glass and minerals that
    were formed in meteorite impacts. They are extremely small -on the order of a few microns in size- and
    very sharp, like clumps of little glass daggers. These could present a hazard to the growing roots
    of plants that have been planted in 'raw' lunar dirt, shredding the roots as they attempt to grow through
    this material. They also present an unknown hazard to the humans who will be living and working within
    this lunar 'terrarium'. An interesting article http://www.wired.com/science/space/news/2005/04/67110
    appeared on Wired a few years ago that spoke about this issue.

    My understanding is that the moon is very much outside of the earths ability to protect life on it from any solar activity. Lacking a field to protect if from a Solar Flare and the harsh solar winds, I would venture that any life 'transplanted' there would be sterilized and elminated sooner or later.

    Wasn't this even a concern for the men on the Apollo mission? I believe there were plans on how to address the the nation if everyone got killed by a solar flare that they could not hide from.

    Space missions these days are well within the protection of the earth, and still very dangerious since some of the Alpha Particles and Solar Radiation still get through.

  82. Photosynthesis != Plant nutrients by Per+Abrahamsen · · Score: 1

    All plant "generate their own food" through photosynthesis. But the only element you get through photosynthesis is carbon.

    When people talk about plant nutrients, they mean the other elements. The most important is nitrogen, then phosphorus, then trace amounts of other stuff.

    Some plants (peas, clover) can sort of get their nitrogen from the air, where it is in plenty supply (N2). They rely on symbiosis with soil bacteria which can bind the N2 from the air to NO3 (or NH4). This costs energy, which the plant supply in form of sugar from photosynthesis.

    Organic farming make great uses of these plant in crop rotations, to avoid the need of mineral fertilizer. But it has a price in total production, so conventional farmers supply the nitrogen needed in suitable form for the plants.

    Phosphorus and the trace elements cannot be extracted from the air, but significant amounts is nonetheless donated freely through the air, from industrial pollution. In fact, the success in combating air pollution is costing the farmers money, as they have to fertilize more.

    For the Moon, I suspect supplying the trace elements and phosphorus will not be the most costly part of the operation. The big posts on the budget is the water, the carbon dioxide, and perhaps the nitrogen. Depending on what can be mined locally.
