Mars Journal Issue Inspires Hundreds of One-Way Trip Volunteers 475

Velcroman1 writes "An interplanetary trip to Mars could take as little as 10 months, but returning would be virtually impossible — making the voyage a form of self-imposed exile from Earth unlike anything else in human history. What would inspire someone to volunteer? A special edition of the Journal of Cosmology detailed exactly how a privately-funded, one-way mission to Mars could depart as soon as 20 years from now — and it prompted more than 400 readers to volunteer as colonists. 'I've had a deep desire to explore the universe ever since I was a child and understood what a rocket was,' said Peter Greaves, the father of three, and a jack-of-all-trades who started his own motorcycle dispatch company and fixes computers and engines on the side. 'I envision life on Mars to be stunning, frightening, lonely, quite cramped and busy,' he said. Given the difficulties of the mission, Lana Tao, the editor of the Journal, said she was surprised by the response. 'At first we thought the e-mails were a joke... then we realized they were completely serious.'" Of course, they'd have to compete with the thousands of you who said you'd go.

      Is how a father of three could volunteer to depart on what would most likely be a suicide mission. Exploration and the battle against entropy and all that is all good and well, but if one is a father, one has certain responsibilities that are paramount about anything else.

      I will probably get flamed to death about this, but I guess in this case, the guy must be either be completely discontent with his lot in life, or he must be the most selfish, self serving person that exists.

        Or, perhaps, his kids are grown?

        Perhaps his kids rarely come visit anyway?

        Who knows. Simply because one has sired offspring does not imply that they are or should be dependent upon one forever.

        Which would be more selfish-- the middle aged to retired man who wants to use the autumn years of his life to accomplish something great, or the children who insist that "pops" stick around so they can dump their kids on him, and otherwise mooch?

        That particular sword cuts both ways, you see.

        • Not that the planners would let him; but any "middle aged to retired man" who consumes a martian launch spot is suffering from a different flavor of selfishness.

          Unless the costs come down by a fair few factors of ten, there is no case to be made for sending any but the healthiest, expected-to-last-longest, specimens...

Note also that once a man hits about 40, you're still fertile but the quality drops. There's a much higher chance of birth defects.

              Let's face it -- by the time we get around to Mars, anything I know will be able to be done by someone younger, who could actually have kids on Mars, and is more likely to recover from injury and the enourmous strain of l

                Why is anyone even thinking about kids on Mars or "breeding teams"?

                I think Elton John had it right in his song on this very theme, "Mars ain't no place to raise your kids". I can think of dozens of reasons that would be a Very Bad Idea, but the major ones:

                Kids are a huge drain on resources-- not just the basic resources like food, water, and space that they'd consume, but also the time of the adult settlers who have to care for them and teach them. Mars settlers need sustainability more than they need their numbers replenished. In all likelihood, settlers would need to, on average, produce substantially more than they consume in order to get a colony set-up and make it viable. Once a colony reaches the level of sustainability that provides an excess capacity of resources (time, food, and water), then and only then would children be feasible within the colony.

                It's also pretty unethical to birth a child, who had no choice in the matter, into that sort of lifestyle. Yes, that argument could (and maybe should) also be made for a number of lifestyles, such as poverty or war, but it is possible to get past those situations with enough effort or a migration. Until 2-way travel is established, life in a Mars settlement is the only possible option for a child born there. Putting someone in that position who never consented to it is kind of shitty.

                On a related note, it probably wouldn't matter what age of adults went on the voyage, within a reasonable range, say 21-50. Not everyone would need to be young, only in reasonably good shape and able to contribute. Just like how a military tends to work, the younger, inexperienced people would do most of the labor and take the physical risks, while the older and more experienced folks would probably be able to contribute more knowledge and experience to the effort, as well as performing lighter labor. There's also the advantage of not having as much "life" to lose if something goes horribly wrong and the settlers' lives are cut short. Regardless of how or when they might die, which all the settlers will do sooner or later, they'd just become soylent anyway. Yeah, I'm pretty sure that's how it would have to go down, at least for a while, there is just too much water and useful stuff in a corpse to let it go to waste in a resource-starved colony.

                • From what I've read, most plans for Mars colonization don't include any sort of breeding population until after an establishment of a sustainable settlement. If you read the entire proposal you'll see:

                  "Crew selection for the initial manned mission would have to take into account several factors. Initially, colonists may be preferred who are beyond their reproductive age, because their life expectancy is likely to be 20 years or less, and secondly, the first settlers will endure some radiation damage to the

            That kind of presupposition trades youth for experience, which would spell disaster for such a mission.

            This is especially true if you need experienced horticultural experts, animal care specialists, and all the other "tools of the trade" types you would need to create a functioning colony.

            If you just wanted to send scientists with a prefab 'Instant research lab in a crate" that they just assemble with a pneumatic torque gun, then yes-- your argument makes sense. However, that is now what is needed by a one-way trip colonization endeavor.

            The people have to be experienced and resourceful. Things that best come with practical experience and age.

            To be successful, the mission would have to incorporate both sets-- the young and vibrant-- as well as the older and more experienced.

            I dont suggest sending invalids up mind-- There are very spry and healthy 60 year olds right now. Instead, I would suggest that all volunteers undergo a skills assessment and a physical, and if they pass both, they are included.

              And blow off the "why". What possible reason is there to colonize Mars? Actually, an even better question is this: how can colonizing Mars pay off? Bear in mind that it would cost billions or even trillions of dollars to get a colony established on Mars. Also bear in mind that Mars is mostly made of iron oxide and silicates - just like earth. Leave aside the enormous initial investment, how would you even recover operating costs? There is literally nothing you could produce on Mars and deliver to markets on earth that you couldn't source more cheaply on earth.

              Investors and/or taxpayers would have to shell out staggering amounts of money to make this happen... what's in it for them?

        Mission date is +20 years. Unless he has more kids, they will all be adults by the time he takes his trip. Other than some grief during the onset of the mission, it's probably no different than the kid that moves away from the area they grew up for better opportunities.

      • Or, you know, he's left his legacy. His kids are well cared for, and perhaps of an age.

        Perhaps he's completely content.

      • If he is a father already, and the Mars mission won't be for 20 years, his children will be at least 20 years old. It's not like he's dropping off the 5 year old at the babysitter forever.

        Of course he is! He's a father, after all. Who else but the selfish can bring themselves to thrust children into this world of ours? You don't have children for their sake, you have them for your own. Immortality, appreciation, social status, tax credits. Children bring a wealth of benefits to the parents, even without counting less tangible things like pride and love. No one has children for any other reason than for themselves. That attitude may change later one, when care and comfort of the children itself becomes the driving force of importance, but it never starts out being about the kids.

          I totally disagree with this.

          Prior to having children, my wife and I talked about the massive expense and inconvenience, and weighed it against our responsibility to THEM, the unborn children. We literally held their lives in our hands (in the form of Birth Control devices), and decided that the right, UNselfish thing to do was to give them life.

Depending on the age of his kids (maybe they are all teenagers?) there isn't much of a role left for him to play. Not to mention, by the time the trip gets off the ground (literally), his kids will have grown up. Also, it's worth mentioning that even non-mars astronauts would have big problems with family life and small kids, as do many other professions. Many business people spend 80

        Oh - now that's something I disagree with and I'll probably get flamed more than you.

        I could be a terrible father. I don't have any children, and I don't want any for a bit (I'm still pretty young). But if I were to have 3 kids tomorrow I would much rather put them up for adoption than try raising them myself. I've still got to pay off my school debt, I've got living expenses of my own, heck I might be switching jobs soon. Money is going to be tight.

        I know it's not morally justified or anything like that, but if I had kids right now I would end up having this animosity towards them that they ruined my 20's, caused me so much stress, caught me unprepared - basically a bunch of negative energy. I'd do my best to be a loving parent but I won't deny that those thoughts would be there. As such, I'd probably make a terrible father. When there are people out there unable to have children, who are much more loving than I and would be overjoyed with being able to take care of my kids.

        Whether that's being selfish or selfless - I don't know. When one option is both better for the kids and better for me, does that make me a bad person?

Further, there would be every anticipation that these people would be the best and the brightest that humanity has to offer.

    But even my longest (currently) planned trip (a thru-hike of the Appalachian Trail) still has me going into town for resupply every week at most and of course ends with me safe back home. On shorter trips I've spent a longer time away from people and civilization (60 days in the woods, but I had made several trips ahead of time to lay in supplies so I didn't need to go anywhere) and it was lonely - but again, in the end I knew I was coming back to the things I felt were "home." Despite going on those kinds of trips (which I venture to say most westerners never even come close to doing), I really can't even begin to imagine what it would be like to make such a trip and *know* that I was never, ever coming back and I would almost certainly never, EVER see any of the people and places I love, and never have the luxury of easy survival that we have here on Earth, even in some of the worst places on the planet, ever again.

    I know there are many people who would volunteer for such a trip - I certainly think it would be pessimistic to think that we couldn't find several thousand people who are qualified and capable of making the trip. Heck, maybe I'd even be one of them, but based on my experience simply removing myself from human company for 2 months, probably not. In any case, people like that "father of three" volunteering just come off as romantic and not particularly thoughtful.

    We don't have anything comparable to abandoning *for sure* everything you know and settling somewhere new in our race's living memory. We have a handful of people alive who were born in the very late 1890's - when crossing from Europe to the Americas was not unreasonable to contemplate doing twice, or being able to send for one's family, or otherwise not cut oneself off from everything you knew. Even Columbus made it here and back - there really would be nothing comparable in even the most charitable definition of modern times.

    Maybe I'm being overly dramatic, but I do wonder what people who could do this one-way-for-sure trip and survive would be like. I have lived without the streets of my city underfoot and the ceilings of my home overhead, but I can't imagine what it would do to me to have alien soil under alien skies and know I'd never set foot on Earth again.

Huge numbers of immigrants to the Americas *knew* it was one-way, the journey was treacherous, and none of it would be easy, and huge numbers of them didn't survive. The human animal is, by nature, an exploratory creature, of course many of us would go. Many more of us would go afterward, over the bones of those before us, armed with what little knowledge their passing gave us, because the hope of success would so mightily outshine any sense of hope left here.

      Pioneers also had a reasonable expectation of finding breathable air, arable soil, animals to hunt for food/clothing, timber and stone for building homes, and drinkable water. Yet, the death rate among most pioneer groups was also unacceptably high (by our modern standards). You almost always had a majority or all of several pioneer groups die in the attempt (Donner party?). In the more modern case of the Spanish, French, and British colonies in the Americas, the colonists had to be supplied from the home countries for years before becoming close to semi-reliant. In the case of the first few British colonies, the mortality rate was in excess of 50% for decades. Even after the US declared independence, the Americans relied on Europe for manufactured goods for most of a century.

    In the 1960's we made it to the moon in 8 years, when NO ONE has ever been out of earth's orbit before the program started. And we got the men back safely to earth. And we did it several times.

    Now, 40 years later, we think it will take 20 years to do a ONE WAY trip to the moon?

    Our sense of ambition disappoints me. We should go to Mars and we should bring those people back. They will be heroes and we should not let them die. I understand that some people think its a waste of money, and other people would rather we go one way then don't go at all, but I'd rather we just go, and quit worrying about the cost (well, I mean we shouldn't waste money, obviously - we should do it as economically as is reasonable).

    If we took just 5-10% of *one years worth* of our hyperinflated military budget (which would give us $70 billion for the Mars trip. That should be enough.), we could go to Mars and back, in 10 years. So, 1% total from the military budget over 10 years. You think Mars is a waste of money? Our military is a waste of money. Lets take 1% of it and do some inspirational work.

    In the 1600's people from Europe went to colonize the new world. They brought with them tools and provisions to start a new life. Few of them went back home, in fact some of the ships that landed on American shores were taken apart for their wood to build shelter. There is a big difference between the colonization of America and the possible colonization of Mars. (Mars can't support life without a lot of technology that must be brought along, the new world was still Earth!) But the idea of leaving home and never going back with only limited communication possible with those left behind is the same. (It will actually be EASIER for the Mars colonists to communicate with their loved ones left behind than it was for the American colonists!) Eventually as the new world colonies grew, so did trade and it became possible for the colonists to travel back to Europe, and the same will happen for future Mars colonists.

    Europe didn't start to colonize the America's until there were large fleets of ships plying the waters of the Atlantic. Until we have the same kind of access to space that 17th Century Europe had to the Atlantic I don't see us being able to colonize Mars. I also think we should establish a colony on the moon first, if for no other reason than to test the required technology.

      A better comparison would be to the "colonization" of Antarctica, except that Antarctica is far, far more hospitable a place than Mars. Not only is it much warmer than Mars, but the atmosphere contains lots of oxygen, and there's plenty of water lying about. It's not cheap to get your gear and supplies there, but it doesn't cost a bazillion dollars per kilo, either.

      Conversely, anyone volunteering to go to Mars - permanently or not - ought to be required to live by themselves in some remote outpost in Antarctica for several years, with only a ton or two of materials and supplies with which to build shelter and sustain themselves for the duration. If you can't figure out how to do that, you have no business on Mars.

    This is dumb, dumb, dumb.

    There is only one reason this is described as a "one-way" mission; Mankind's incredibly stupid reliance on chemical rockets. Chemical rockets *will not* allow us to explore any of outer space in a meaningful way, with the possible (and expensive) exception of near earth orbit.

    We already have the technology to jet where-ever we want around the solar system. Project Orion [wikipedia.org].

    There was a BBC show [bbc.co.uk] on it.

    The short story: It was a design to use small nuclear explosives to push up against an abalative impact plate with shock absorbs. One pulse every 120 seconds. Significant levels of acceleration, and a mass to energy ratio that would make any rocket scientist blush. We could *easily* send a million ton spacecraft to Mars, with more than sufficient fuel to return several massive (10s of thousands of tons) spacecraft back to earth.

    We could do round trips every 6 months without blinking an eye, with the added side effect of using much of the world's weapons grade nuclear fuel. Enhancements to the design switched from Fission to Fusion; at which point Orion spacecraft would be able to start to move around interstellar space. Early designs using current materials could achieve 0.05-0.1c . Designs using future materials (or possible relying upon non-solid ablative surfaces (this includes a plate that is sprayed with an oil solution before each blast)) could theoretically achieve .8c . This would make round-trips to Alpha Centauri possible.

    How do you get around the nuclear radiation issues? Simple. First, there's no serious issue with radiation in space; build it in orbit, and there's not much to worry about. Second, the fallout/radiation from direct planetary launches would be dwarfed by weapons tests that occurred in the past, and probably by fossil fuel plant emissions, as well. The total fallout released from a planetary launch of a 6,000 ton vehicle would be equal to a 10-megaton nuclear blast (roughly one worldwide instance of cancer per launch), even using thermonuclear blasts. Further refinements to the technology could significantly reduce that; and mankind has pursued far less interesting pursuits that have caused a great deal more fallout (and heighted rates of cancer) than a real, "nuclear" space program.

    In an ideal world, we'd build a few *huge* orion stations, and launch them into orbit. I'm talk multi-million ton hulks. The fallout from these launches would be significant, but would still be smaller in magnitude than the fallout from the various nuclear weapons tests that occurred during the cold war. These stations would contain the industrial complex needed to build additional ships, and smaller vessels capable of mining the needed materials from the moon. Hopefully, there are sufficient levels of fissionable and fusible materials on the moon. At that point, man kind could return to using chemical rockets as ferries to get into space; to deliver small cargos and personnel to the constructions stations.

    How would you pay for this venture? That begs the question: Whats the best way to profit of a massive nuclear pulse drive in space? To move asteroids! Mining of the asteroid belt would be a serious proposition, and the low gravity (and lack of atmosphere) makes the usage of our Orion drives even more palpable. It would be necessary to figure out a cheap way to return these metals to earth; however, initial studies have suggested that even very small asteroids (1 mile diameter) can contain tens of trillions of dollars of metals.

    The loss rate would be terrific, but one could imagine breaking asteroids into 500 m chunks, surrounding them with layers of ceramic heat shield, and them aiming them for the middle of the ocean, Siberia, or other wasteland type area. I have a feeling we can devise a more elegant solution over time.

    This could happen in our life

Every nonzero finite dimensional inner product space has an orthonormal basis. It makes sense, when you don't think about it.
