Forget Mars. Should We Go To The Moon? 511

Posted by michael from the green-cheese dept.
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?"

    This story brings up a good point... I think we should go to the moon... Learn a lot more with todays science applied there.
    • Don't projects work best when you take small steps. In the past first we went to space, then we stayed in space longer, then we finially went to the moon. It makes sense to take steps here. For safety and to be prepared. We should go to the moon before we go on.
      • Of course every new major device will be tested before it's fully depended on. That's why the 60s and seventies saw Mercury, then Gemini, then Apollo. Every stage had to be thoroughly tested before the next stage was safe enough to be tested.

        Today, technology to get unmanned craft to the moon is quite mature. We need only extend our knowledge of modern manned mission technology to reach the moon. And that should be cheaper than developing that technology all over again.

    Doesn't this, in a way, come down to an issue of long-term goals for space exploration? The costs of putting up a station of sorts on the moon would no doubt be immensely costly. If we just plan to run a few missions to Mars, it really doesn't seem very cost-effective. If someone has solid numbers I'd like to see how the distance moon/Earth would be to further planets such as Jupiter or Neptune. Also how big of a factor is the gravity difference in the long run for travel. If we could turn a station on the moon into a pseudo-colony, I think that would have some nice potential for space travel and perhaps even more affordable space tourism.

      Yeah, "if". But what if it can't be done? There is no chance to make an Antarctic colony, where the conditions still are much more friendly than on Moon. I doubt if there is any chance to make anything colony-like on Moon - there is no serious plan how to make water and oxygen on the lunar desert (not to mention food or anything useful). All we hear are Star Trek-like hypothetical scenarios, that maybe there could be some frozen water. Well, what if there isn't? The comparison of the Lunar colonies and the New World colonies of XVI-XVII century is fundamentally flawed - Columbus did not have to carry oxygen from Spain. Heck, he could even repair his ships from the wood found on the new continent. He arrived into a land where human beings can sustain their own living - it was far from uninhabitable desert that we have on the Moon or Mars. We can't have an underwater colony somewhere in the middle of an ocean. We can't have a colony on Antarctic. What makes anybody think we can have a colony on Moon? Is it just because once there was a TV series [space1999.net] about one?

For everything we can reasonably expect to accomplish, unmanned probes, rovers or orbital telescopes can give us much more bang for our buck given our current level of technology.

          It actually requires more delta-V to soft-land on the Moon than it does to aerobrake and land on Mars. This requires a different (bigger) launch capacity, under conditions where you also need to carry supplies which a Martian expedition can produce locally.

          We still need the ability to build a shelter in a foreign world with little resources.
          The character of those resources is extremely different between the two worlds. The Moon's resources are heavily depleted in volatiles and relatively un-differentiated, with lots of native (reduced) metal in the regolith; Mars' include an atmosphere full of oxygen, carbon and nitrogen, heavily oxidized materials and differentiated mineral deposits including hematite. The experience gained on one isn't transferrable to the other.
          Perhaps more importantly, Luna could be used to test automated systems that will help us on mars.
          You can test software in your backyard on Earth. What you really need testing for is hardware, and the hardware designs necessary for conditions of hard vacuum and a 28-day sol are very different from airborne dust and a sub-25-hour sol.

      I belive that resupplying a Moon base would be as expensive as resupplying a Mars base and could even be more. The main cost is boosting mass out of Earth's gravity well which you have to do in both cases. To land something on the moon you also have to carry propellant to decelerate to rest on the surface. Landing something on Mars you at least have the option of aerobraking, reducing the amount of mass that needs to be sent. For supplies, cost would have little to do with flight times.

    Apollo astronaut Harrison Schmitt had a wonderful editorial in Aviation Week and Space Technology a couple of weeks ago, which is similar to this testimony before Congress [spaceref.com]. In it he laid out an arguably sound economic case for mounting a large-scale mission to the moon to mine Helium 3.

    Helium 3 is present in abundance on the moon, and on a per-pound basis could be one of the most valuable substances there is. Assuming that one really could catalyze nuclear fusion in power reactors using Helium 3, it could have profound implications -- allowing us to move beyond hydrocarbon fossil fuels (although, ironically, you'd still need those fuels to power the rockets to the moon.)

    I'd seen pie-eyed schemes for going to the moon for the Helium 3 before, but Schmitt really tries to nail it down, and answer most obvious criticisms. It's definitely worth a read.

    Going to the moon, and then using it as a launch pad to mars is total bunk. It would be similar to doing a trip 100 miles away by taking the first leg of the trip 3000 miles away and then coming back. The hard part about going to Luna or Mars is getting off this rock. If we use Luna as a launch pad, we will still have to launch from here to there with just about everything, then re-launch it again. Totally F.U.
    OTH, it does make sense to use luna for a test bed to build an automated system for building a colony. In particular, we need to build rockets to launch large loads. Likewise, we should send automated systems ahead to carve out a home/cave in the ground for us. Colorado School of Mines was recently given a lasar for drilling in the ground (via the US military). This could be used to literally build several holes in the ground for living in. From there, we can expand easily enough.
    Once this is perfected, then send a number of teams to Mars to live out their natural lives. They should be going to colonize the planet rather than plan on going there and coming back. And yes, there are plenty of bright people who would be willing to risk it all for a chance to settle on a new planet.

    It is important for humanity to colonize other worlds for several reasons. First, it gives a degree of protection from disasters of the sort that killed off the dinosaurs. Right now, we have all our eggs in one basket, ripe for extinction. Second, we can't stay on this planet forever, eventually (in a long long time) the sun will die, with it the capacity to support life on this planet. We may have to leave sooner if, as seems likely, we exhaust the natural resources of our lonely planet. Anything that is inevitable has to be faced, the sooner the better.

    The moon is important because it will give us valuable experience in colonizing other worlds, and do so fairly cheaply compared to Mars, Europa, etc. Even if the Moon is a bad site to put telescopes, the knowledge gained by inhabiting another world is irreplaceable. There probably exist problems of colonization that haven't been forseen yet, and the only way to discover these problems is to try to do it. We may lose lives in the process, but that is a small price to pay for the continued survival of the species. I don't think they would have any problems finding volunteers to go, I know I would go in a heartbeat.

    I dream of the day when we have colonized all the habitable planets and moons in this solar system, and the debate rages about whether it's worthwhile to invest in colonizing others. Same debate, same short-sighted folks complaining that it's too much money for too little gain.

    Building a throwaway spaceship and going to Mars just to wave a flag and grab samples of microbial life is really a waste.

    It would be better to start getting a sustainable foothold in space, opening up the opportunity to start scooting around the rest of the solar system

    We need a small fleet of reusable modular spaceships that can be used for a mission and then can be parked in orbit and replenished to be sent out on future missions. The landing component for Mars and other planets should be the only throwaway component.
    The Moon can be a source of materials that are cheaper solely because you don't have boosting the mass into earth orbit.
    In the same way, in the long term, a manned subsurface base on Moon is a cheaper option for maintaining the engineering crews and astronauts themselves, between missions.
    The low gravity and vacuum in space provides some opportunities for new manufacturing processes, which could also provide a source of revenue for the entire space program.
    Asteroids have the potential for providing sources of material for both the new manufacturing processes, creating orbital stations and even new space ships.

    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!

    Aside from questions of the human need to explore and the possible economic and scientific benefits of human exploration/colonization of the solar system (including of course the moon and mars), we need better propulsion systems than we have now. Even though the moon seems to be the best stepping-stone to further exploration, we still have to get out of Earth's gravity-well to get there. With chemical propulsion this is and always will be just on the edge of economically impossible (i.e. extremely expensive therefore almost impossible). In addition to that, with chemical propulsion everything in the solar system, including the Moon, is very far away. Orion-type nuclear pulse propulsion systems are at the very least politically impossible right now. Ian Wright was quoted in the Nature article as saying: "To not travel beyond our planet would be like living a few hundred years ago and not wanting to explore new continents." The Europeans didn't explore the world until they had ships which were up to the task. To me it seems that the better expenditure would be on research into better propulsion.
