Another Small Step Before the Giant Leap

Armchair Anarchist writes "Over at Futurismic, a new column proposes that NASA's plans to establish a lunar colony are an attempt to run before we can walk properly, and that developing orbital habitats first would be a wiser and more realistically attainable project. From the article: "... it seems to me that the trump card is with the orbitals; orbit is closer, cheaper and easier to get to, and offers more flexibility as a long-term outpost. Sure, let's put men back on the moon, mine it for helium-3, research its history and origins. But it makes more sense to launch missions of that type from an already-established colony in orbit.""

  1. A good point by Aladrin · · Score: 4, Insightful

    I think they have a good point here. We've been working on a 'space station' for quite some time and barely have anything to show for it yet. How much planning could they possibly put into a moon base yet? The basics are pretty much like earth bases, and the long-term effects of no/low-gravity are not really known. So it'd be like designing a regular earth base with airlocks, and huge gaping holes where they are going to put the unknown things they'll need once they understand non-earth living.

    Just a bit premature.

  2. One simple reason by ysachlandil · · Score: 5, Insightful

    One reason: Gravity. They have it on the moon. They don't have it in orbit. Makes showering, sleeping, eating, everything more comfortable. Plus the fact that you don't have your colonists dying of accidentally bumping into something and breaking all their bones.

    A colony implies people living there for longer than 10 years. Zero gravity is a bitch at 10+ years.

  3. Better Plan by Alsee · · Score: 4, Insightful

    As much as I want us to return to the moon and get to Mars and beyond, I think we're going about it all wrong. We're sending people up on top of insanely expensive fireworks. It's just plain too expensive. It's not practical or sustainable.

    Instead of blowing insane amounts of money on the space station and on unreasonable shuttle launches, we should be pouring those exact same dollars into RESEARCH on better and cheaper means to reach space. Whether it is beamed energy launch vehicles, rail-gun like ground launch facilities, a space elevator, scramjet engines, or who-knows what other tech, we will be far better off if we (temporarily) sacrifice the manned space program to sink the up-front dollars into cheaper access to space. Once you have that cheaper access, then future dollars will provide vastly greater dividends in future practical sustainable manned space development. Then and only then can we establish practical and sustainable oribtal facilities and a moon base and even a SUSTAINED Mars base presence.

    As much as I would like to see us get people to Mars, I don't want a replay of the Moon joke. Over-priced impracitical throwaway missions... and we haven't been back there in THREE DECADES. I do not want a throwaway mission to Mars. As nice as it would be to get people there and get dome decent science out of it, it's just NOT WORTH IT to do a tera-bucks throwaway mission to land a couple of people for a holliday vacation and then abandon Mars for two or three of four decades.

    I'd rather wait a while for that first mission to Mars and then see it done right. Do it when it makes sense to do it. Shift the current spending to more robitic missions and probes across the solar system, and shift the spending to development of more efficent space access technology.

    So I am opposed to our current manned program and I am opposed to the various proposals for more manned missions... and I do so out of my deep desire and support for manned space projects.

  4. need more than a rowboat and a tent by maddogsparky · · Score: 4, Insightful

    Look back at exploration prior to the 17th century. These trips were made in small ships that were marginally self-sufficient. They sailed with extra crew because they _knew_ they were likely to return fewer in number, if at all, and had to have a minimum number of people left to sail. They were equipped to sail for intermediate lengths of time, but not well suited to long-range exploration. They sailed with pretty much only the materials they were expected to need, and if they ran out of something important, they tried to limp along until they could get back to a port.

    Compare this with later ships that circumnavigated the globe on multi-year expeditions. The ships tended to be larger and more self-sufficient. They included things like portable blacksmith shops that could repair and fabricate unknown articles as needed, manufactured from stock materials that were also brought along.

    Now that private companies are showing some proficiency with tasks that were previously only the domain of government (e.g. launch capabilities, manufacture of orbital habitats and facilities), NASA should concentrate on the next step in exploration. If they want to explore (which I fully support doing), they should concentrate on developing things which support exploration that nobody has done yet. Support tasks, such as launch capability, habitats, etc., should be farmed out in competitive contracts or Grand-Challenge style contests.

    A moon base is a logical step, but it is really just a support role. NASA should farm this out or indicate willingness to purchase capabilities and participate in evaluation, but should focus on creating long-range exploration capability. After all, even Columbus's trip was government financed. Once people became aware of the investment potential, they financed new ventures themselves and eventually opened up what had been exploration efforts into commercial enterprises and settlements.

  5. Article has Logical Errors by StCredZero · · Score: 4, Insightful
    This article has serious logical errors. He's constantly using "bait and switch."

    1. To refute the point that an underground lunar colony would be better protected, he states that a large enough meteorite would damage any lunar colony. Duh. What are the relative probabilities for the larger meteors? Much smaller for larger rocks. His argument here is vacuous.
    2. To refute the point that the moon has gravity for the health of the astronauts, be points out that larger stations will be built to use centrifugal force. But isn't he advocating the completion of the ISS as one of his major points? My understanding is that this won't use rotation to provide artificial gravity.
