Forget Mars. Should We Go To The Moon?

me98411 writes "We have discussed earlier about the President's Commission on Moon, Mars and Beyond and about how a direct trip to Mars is the way to go (or way not to). In a BBC article, the division in the astronomers and space geeks community about the use of the Moon as a base to develop ways to travel to Mars is highlighted. Now, Nature is asking: Should we go back to the moon? Is a manned mission to the moon even necessary?"

      The short, glib answer is: because Mars rockets don't grow on the moon.

      The cost and effort to build a moon base which can support humans long-term is already pretty high. Then you have to build facilities for building and launching Mars missions. Unless you want the additional cost of lifting raw materials to the moon for manufacture (or even just basic parts for lunar assembly), you also have to come up with equipment and processing infrastructure to use the raw materials up there -- and even then, probably only a fraction of necessary materials are realistically accessible.

      So before you've even launched your first Mars mission from the moon, you're already mired in this enormous project just to make the moon useful for that task.

      By a HUGE margin, it would be easier to just use existing Earthside resources, manufacturing infrastructure, and launch facilities to go straight to Mars.

      I also believe there are good reasons from the orbital mechanics perspective to go straight from Earth, but I forget the details.

Increased cosmic radiation, long travel times, increased communication lag, etc., etc. Establishing at least a preliminary base on the Moon would allow us to sort out some of those challenges before sorting out the rest.

Why waste all that time & money on the steps in between? Because they are value added & achievable goals.

      On the other hand the moon is much closer, and the potential in-flight radiation risk is much less. And communications would be much easier. Rescue missions to moon would only be slightly more a pro moon stance due to the set up time to launch such mission.

    A base on the moon would be a lab to try out all things nesessary for a functional base anywhere else. Just to test shielding and life support in a different environment from the ISS and improve reliability. This would be reasonably close for safety and replenishment/repair. This is a good idea. No one has any experience colonizing another planet yet and taking baby syeps is a better idea. The launch site idea can be delt with later, but the cost of moving everything to the moon seems prohibative.

    These are two completely different places. The Moon has no atmosphere to contend with, lower gravity and would make a great place for testing technologies needed for exploring/ exploiting asteroids.

    Mars is more like the Earth, in that it has atmosphere (and so weather) and would be a better model for eventual off-world colonisation in other solar systems, should that ever be possible.

    If a choice had to be made, I would prefer a permanent base on the Moon to a brief visit to Mars. After all, if its turns out that there are enough resources on the Moon to exploit, possibly we could make mass drivers to boost these into Lunar orbit for manufacture of space industries or vessels without the fuel cost of lifting things from the Earth. How about a test space elevator made on the Moon? (I can see the headlines: elevator from nowhere to nowhere!)

    Also, what happens if we find life on Mars - even of the simplest form? Could we then exploit the planet in any way that would avoid destroying this?

    Why?

    To discover the things that we don't know about living in extraterrestrial environments - BEFORE we strand a group of humans 2 years away from earth.

    For example, we have little to no data about the effects of radiation on humans beyond the earth's magnetosphere. This is one of the biggest concerns especially considering most of the proposed trips to mars exceed one year of travel each way. Creating a base on the moon will give us a better idea of the concentrations, and the long term effects of solar radiation on humans.

    The moon's low gravity also makes it easier to access. Less fuel is needed to land, and take off.

    I think though that the biggest reason for going to the moon first is an old saying "walk before you run". In terms of distance the moon is on average 240,000 miles away from the earth. Nothing really, in the grand scheme of things. If for some reason something went horribly wrong, there would at least be a chance to rectify it, or help. A moon base would be a stones throw away, and with the proper planning the crew of that base could be very safe.

    From a scientific perspective examining the individuals that do staff the base will provide vital information about what living in the solar environment is like and how if affects the body. Also, the moon has 17% of the earths gravity, with mars at 38% the moon makes a good environment for training for low gravity.

    All in all, I think that we cannot afford NOT to go to the moon first. The moon gives us an opportunity to learn about living in space without the risks of being completly isolated from humanity.

    Make no mistake - the moon must be the beginning - and not the end of our future in space!

    How do you know how sincere Bush I's plans were? AFAIK what killed those plans were the media and the public's reaction to the $400b price tag.

    Cancellation of all current space efforts (Shuttle, Hubble, Space Station, many other NASA projects, ASAP).

    The cancellation of the shuttle was called for by many space proponents. It is simply not capable of doing what it was designed for, and most missions it carries out can be performed by EELV's. The space station has questionable scientific value. The Hubble was scheduled to be replaced in the 2010's anyway. You can make good arguments for the cancellation of all.

    Proof of the plan's vaporware nature is that there was no mention of this "vision" in the State of the Union speech that occurred the very same week.

    Where is it stated that every initiative of the president has to be mentioned in the SOTU? How is not mentioning this in the SOTU proof of anything?

    GHWB also had a problem with the "vision thing" and came up with similar smoke and mirrors about Mars before his own doomed election effort in 1992. As an indication of his insincerity, he put Dan Quayle in charge of the effort.

    It's not the same thing. Columbus was not running a scientific experiment or a "voyage of exploration." It was a fairly coldly-calculated commercial undertaking, even if a somewhat risky one. He could honestly answer the question by making several points:

    • Except for the religious zealots, we all know that the world is round. Heck, the ancient Greeks made estimates of the diameter as a geometry exercise. Ocean sailing has its dangers, but falling off the edge of the world isn't one of them.
    • The transport technology is well understood. Portuguese sailors currently cover the same kinds of distances I'm talking about. It's not "routine", but it's clearly possible.
    • On a national scale, this is NOT an expensive undertaking. If I'm successful, the value of the cargo I will bring back ON THE FIRST TRIP will cover the entire cost.

    Granted, if Columbus had done his sums right on the circumference, he probably would not have made the attempt, as the resulting open-ocean voyage would have been beyond the reach of the technology of the day. As others have pointed out, much of the expense of doing things in space is the cost of getting significant masses as far as LEO. As I have written before, if the government wants to see us make a go of things in space, spend the money to develop cheap ways to get to LEO. If you could get stuff that far for, say, $2 per pound, all kinds of things become quite affordable and practical.

    Your point, which I understand better after your follow-up, is that we shouldn't be primarily motivated by the "because-it's-cool" factor, and we might as well let our technology develop to the point where we could go *if* we found a good reason. That's a better argument than just saying "too expensive and too dangerous." The only problems I have with it are 1) the insurance argument and 2) technology will develop much faster with an actual goal (i.e., put humans on the Moon in 10 years) driving it, and might never develop without one.

    Your answer to 1) might be that we can't put a number on the risk of sudden extinction, to know whether it would be justified to focus so many resources on the problem. Your answer to 2) might be, what's the point of developing the tech in the first place, if we don't really *need* it?

    Should we just throw up our hands and give up?

    Of course not. But the money should not be spent today on a glory shot. It should be spent on R&D towards developing the technology to make moon and/or mars colonization viable. Technology like:

    1. Much much much much much cheaper and reliable launch technology.

    In the 1930's, rocket scientists dreamed of being able to launch things into orbit. But rocket technology simply was not capable of it at that time. There's a HUGE difference between an A-4, and the first orbital-capable rockets. And just because the Germans had an intercontinental bomber drawn up on paper in the early 1940's doesn't mean that it would have worked (it would have burned up and damn quick).

    Giving up on X-33 was a bad move towards the above goals.
    Giving up on ALL space research, except that which gets us to the moon and mars for the "glory-shot" is a bad move.
    Pumping huge sums of money into an ill-advised Missile Defense boondoggle, instead of slow and methodical R&D drive for the above technologies, is another error of colossal proportions.

    We were on the wrong track before. But now with the Bush plan, we're nowhere near the right track. A glory-shot is fine and dandy for national pride, but it accomplishes NOTHING if we can't effectively exploit resources on the moon and mars.

    If you want to draw up historical parallels, look at the "Native Americans". They crossed over a land bridge, or glaciers from Northeast Asia. And were cut off from their cultural source. Because they did not have the technology to maintain communication and trade contacts. Their "colonization" of the Americas is not regarded as a huge cultural achievement.

    There were several anchors, of Chinese design, many hundreds of years old, found off the coast of California. Yet there is no other evidence that they landed, or stayed very long, or settle,d, or colonized. It's little more than an academic curiosity.

    Few people know or care about Leif Ericson's settlement in Vineland, in the 10th Century.

    Columbus got all the glory. Because HIS journey was feasible. Not only did he GET to the New World, but they were able to build sustainable settlements, colonize, conquer, and prosper. Columbus had ships that were more reliable, protected sailors better in storms, and for longer periods of time, carried more supplies, more cheaply.

    The Native Americans, Chinese, and Vikings can brag all they want. But real change resulted from Columbus.
