Will Mars be a One-way Trip?

alexj33 writes "Will humans ever really go to Mars? Let's face it, the obstacles are quite daunting. Not only are there numerous, difficult, technical issues to overcome, but the political will and perseverance of any one nation to undertake such an arduous task is huge. However, one former NASA engineer believes a human mission to Mars is quite possible, and such an event would unify the world as never before. But Jim McLane's proposal includes a couple of major caveats: the trip to Mars should be one-way, and have a crew of only one person."

      a round trip isnt really feasible. the moon was a round trip because all they needed was the dainty little capsule to leave the moons gravity and reenter the earth's. a round trip to mars would require the vessel to have a mechanism for standing itself back up once it landed (to accomplish this with something like the space shuttle, you would need your one man to build the infrastructure of a launch site), and still have room for a second tank of gas. i believe it would be a better idea to first send a few drone ships to land and automatically prepare a base to receive humans.

      > b) it alleviates population issues

      I believe the population argument is bogus. Increasing wealth and standard of living is strongly correlated with decreasing fertility rates in every culture and nation on earth. Most population projections which include this effect show the earth's population peaking within 100 years, and then declining, and it's unlikely that a significant colonization effort will be underway within 100 years. (Sorry, can't find the population references.)

      So, there's Scenario A, in which we all get richer, and the population problem stabilizes, so we can't use it as an argument to go to Mars. There's Scenario B, in which we don't get richer, and consequently can't afford to go to Mars. And of course there's Scenario C, in which a small group becomes very rich while the teeming masses remain poor and continue to reproduce -- in this scenario, the small number of rich people who can go to Mars don't substantially alleviate the population problem, because there aren't very many of them.

      There's also a Scenario D, in which a small group of rich people innovate to make trips to Mars affordable for the teeming masses, but I think this is really Scenario A again -- if Mars-going technology is mass-affordable, then many other good things are also mass-affordable, which means that the masses have a high standard of living, which means they already have low fertility, and the population pressure, again, is low. A real Scenario D requires that Mars-going technology be somehow made much more affordable than terrestrial travel, energy, education and birth control, which I would rate as theoretically possible but unlikely.

      Personally, I find manned space travel inspiring, but I think it's important to be clear-headed about exactly which problems it does and does not solve.

He was contending for the Orteig prize for the first aircraft to fly New York/Paris (either way) non-stop. Several previous attempts had ended tragically, and Lindbergh was convinced they failed because previous designers had not paid enough attention to various safety margins, especially those relating to weight and fuel. Thus he designed a plane that put fuel tanks in every conceivable space (including the place where any other aircraft would have had a windshield!) and did everything he could think of to minimize weight.

    That's why he flew alone: it's not that hard to stay awake for 36 hours, and so he saw a co-pilot as unnecessary extra weight.

    Ironically, he got lucky and didn't drift off course as much as he assumed he would, arriving at Paris with enough leftover fuel to continue to Rome. But he designed his plane on the assumption that he would not be lucky. He was a safety-first guy, that's why he succeeded where others failed.

    2. Build a large number of these rockets, hundreds of them. This is the big difference from NASA's current one-off thinking.
    3. Build a big wheel-type space station in Earth orbit, using several hundred launches of the big boosters. This is the base for the Mars shot.
    4. Use about 400 launches (!) to move the Mars fleet of 14 rockets into Earth orbit, along with the necessary fuel.
    5. 14 rockets take off for Mars, with about a hundred people.
    6. The rockets land on Mars on wings. (This wouldn't work. Von Braun didn't have data on Mars' atmosphere. Back then, it was thought that Mars had maybe 20% of Earth's atmospheric pressure. The actual number is about 0.6%. This is a serious problem. We do not, in fact, know how to land a big load on Mars. The combination of heat shield and parachute used for small robotic craft isn't enough. Power is required, which means lugging fuel for landing.)

    It is tempting to scale up the Apollo program when looking at Mars. However, the concept of a single multistage rocket is perhaps not the way to go.

    If Mars goes around the sun in about 2 earth years, then there is an elliptical orbit that is tangential to mars and earth that will represent the minimum energy routes to Mars. The trip would take somewhere between half an earth year and half a Martian year - let's say about 8-10 months. You could get to Mars faster if you kept your foot to the floor, but that would waste a lot of fuel. So - this route is not far from the optimum route you might take even if you had ion engines, provided our two planets were in the right place.

    The craft has got to be big. It has to have room enough to live in for a year or so, with backup. You could strap some enormous chemical rocket that was shipped into space. However, suppose you launched the thing without anyone inside. It can sit in space for years. It could be slowly be raised in orbit using earth-moon tidal forces with ion engine pumping, and a final slinghot. Having escaped the earth-moon system it could slowly accelerate using ion engines or solar sails to get towards Mars. It would take a quick slingshot or aerobrake around Mars and head back towards Earth. If it is in the right orbit, it could get back to Earth without any propulsion, and have enough velocity to get back to Mars' orbit again. Now it is going nice and fast, our passengeers can get on. This time, we are not accelerating the whole living environment, but just the people and their hand luggage to get them to the rendevous, and a conventional rocket might do for that.

    Once we have got this far, we then have a big, habitable volume going between Earth's orbit and Mars' orbit. With a bit of fine tuning, we can probably arrange for it to pas Mars and Earth again. This means if we can generate fuel on Mars for a lifting body to get people to rendevous with the big craft, then going back is not only possible, it is almost free, particularly if you are taking a relief crew out.

    Do you remember the bit in "The Right Stuff" where someone proposed and volunteered to go to the moon in the hope that they could be resupplied until a vehicle for the return journey could be built? They didn't do it then. I guess we won't do it now. It is interesting to wonder why we would go through huge expense to return one person when we have so many, and the same money would save more lives in other ways. However, we won't do it if we don't have to, and I don't think we do.
