Will Mars be a One-way Trip? 724

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."

    The reality of large Mars missions is that the human is only along for the ride, sort of like a color commentator, to help snare the public's imagination and more funding.

    In other words, even one human is already redundant. After all, what can go wrong go wrong go wrong go wrong go I'm sorry Dave.

    Bullshit. If the mars mission is actually doing useful work, then having people physically there will make the work much more efficient. Humans on mars can make decisions in real time. The latency of radio signals makes trying to do anything significant remotely really obnoxious.

    In the end everything is useless anyway but a mission to mars is fun for the whole species.

    See, instead of everyone looking at their navel, people will start raising their head and will start looking at the stars. Instead of having most people working for their own goals, people will start to share a dream. Instead of fighting each other, people will start to work as a team.

    I'm currently working in the field of psychology and even though I'm not high on the ladder, the calls I receive are about couples breaking up and people complaining of surviving instead of living. A lot of people are living without knowing what to do with their life and this is the kind of goal that might bring people together and give them something to do with their life even if in the grand scheme of things it is useless.

    Also, about the benefits, you can't go wrong with studying how to negate the effects of loneliness which apparently affects tons of people that live in cities. Also you get to fight back bone problems that are not that different from the problems aging people have. Of course, you also get the technologies for space travel but you don't care for that that much.

    So is it worth it ? I say sure, why not?

Or maybe he's suggesting that upon arriving at Mars, the astronaut will have an unlimited supply of hot women and baguettes?

    And the whole 'constant communication' - umm.. last time I checked, Mars was between 3 and 21 light-minutes from Earth.. that means you say something, and get a response in a half-hour later.. yeah, that's really constant. It would be more like a video postcard than a conversation.

    Biosphere 2 was an experiment to simulate earth's natural environment and be self-sustainable.

    The colony on Mars, on the other hand, needs only to be self-sustainable. This means that they can skip all the "pollinate with bees" crap and concentrate on producing O2 and food via artificial means.

    As for moon base, given the nature of the moon- ie radiation, micro meteor, lack of atmosphere, etc. I would say that while a moon base is easier to do in the short run, a Mars base has a much better chance of being sustainable.

    As for contamination- don't be silly, of course we have contaminated Mars. The question is, in what ways?

    Round-trip tickets are only useful for tourists, and the real reason to go to Mars is to colonize it, not to take some snapshots and then go home again. We are doing that already with robots, so there's really no point in doing it with people.

    The interesting idea here is not the one-way thing, but the one-man, one-way thing. The author is right, it's initially kind of a shocking proposal, but when you stop to think about it, we're just a bunch of wusses. Our ancestors did this kind of risky one-way shit as a matter of course. (Think of how the Polynesians colonized the entire Pacific in simple canoes.) There shouldn't be anything shocking about it at all. We're just not worthy. Some other culture will do this, and we'll talk about how barbaric they are for trading so callously in the lives of their astronauts. But I guarantee the astronauts will go willingly, and while we tut-tut their backward ways and high mortality rate, they'll be conquering Mars.

    McLane talks about psychology differences of current astronauts vs the US astronauts of the 1960s and the Russian cosmonauts.

    Spending time talking about how the old guys had the right stuff and spirit will carry them through and make the difference is just ya-ya silliness in place of real thought. That is the same kind of thinking that convinced the French that light artillery was just the ticket to face the German threat. The French assumed (naturally) that their soldiers could and would overcome any burden with their miraculous Esprit. Worked really well for them.

    Real "problems" have real solutions based in the real world. I disagree completely about the Right Stuff fluff, but in any case, today's astronauts are the ones you have. Deal.

    Agreed completely. The farther away, the longer the signals take to get to/from the remote destination. The Mars landers could only creep ahead because the operators here on earth couldn't risk just sending them blindly along. What allowed the Mars landers to cover so much ground was the many months they were there having operators move them around inch by inch and foot by foot.

    The astronauts on the moon were able to scoot around like crazy on the rovers. Being there and operating something in real time would be a huge benefit to research of any kind. Instead of sending the command to have a camera pan around to decide where to go next, waiting the 20 minutes or so for it to get there, waiting another 20 or so minutes for the video feed to even start arriving, and you see the issue. A human could just look around and hit the gas pedal. Yeah - that rock over there looks interesting.

I will concede that was 'a matter of course' in our past, it is not our current reality.

    Well because there's a point when it becomes too expensive. Where is that threshold. 10 billion, 100 billion, 1 trillion, 10 trillion?
    Well, the American people gave their implicit approval to a relatively useless war. A trillion - half the cost of the Iraq war so far - seems like a reasonable amount to pay to get to the moon, start a colony, and then begin the march to Mars.

    Of course, at a measly $20 billion a year, it's going to take a real goddamned long time for NASA to get us there.
  • 1. Parent is dead on; wish I had mod points.

    Mars could already be a shorter trip (each way) - that we know MUCH more about, and have more ability to deploy resources for - than Magellan's was, just as an example.

    But, I have two opposing points:

    2. Think of the robots. Basically, we have robots now, which simply are better for this kind of exploring. So we don't need a human there to EXPLORE Mars (or the moon.) Obviously the current rovers are massively, massively cheaper than a manned mission... and I think we could get more done with hundreds of rovers than some dude. a) For any given cost, the robots will probably do the exploring better. In other words, I think we should send a person to Mars when it's economically profitable to send a _person_ there compared to the robots. We just don't NEED some guy to go there anymore.

    b) I think the cost involved in a human mission would be tremendous if the gain is largely symbolic. You don't go there just to touch it, you go there to find out a lot more about all sorts of things you didn't know.

    c) So the other reason to go there is to _colonize_ to really expand the scope of human life to a new place.

    c) in my opinion involves either: i) generate resources FROM Mars instead of spending a ton to be there or to ii) have a sufficient breeding population of humanity off earth that we'll survive a colossal extinction event. I believe i) will come before ii) AND I think i) is more likely to be done by remote control, too... or at least most of it. So wait for a NEED for a person - which personally I feel like will be a long time coming; the robots will get better faster than our ability to cheaply get a person there So maybe the first person will be a paying tourist.

    3. While I think Mars is close enough to be within reach, there are things we've skipped. I think all of the above applies to the moon, but I think it's so significantly cheaper to send stuff to the moon than to Mars. We're just finally going to put a telescope on the moon... For that matter, I think we should have orbiting solar power pretty soon.

    We only have like 3 people living outside our atmosphere. I think that's shameful in some ways... but there's no reason we need to "touch" Mars with a real person before we have commercial occupation of something closer / cheaper* - the technology we need for that to be sustainable - longer term, more sustainable, cheaper inhabiting of harsh environments - is something we can demonstrate much closer.

    *unless it turns out a person on Mars would help us mine something ridiculously expensive, or something. But a cluster of robots could have a higher chance of finding that for less money.

    I'd certainly accept that having the nice thin unbreathable atmosphere there might involve some cost savings in radiation damage/shielding, pressurization, etc. But that's only a justification if those costs are going to outweigh the much-higher lift costs and the much-lower chance of a bail-out.

    The good news is we're getting there - commercial boost to space is becoming practical, commercial space tourism is growing, and that means soonish a space hotel could be a reality - and as costs drop, hopefully attendance will increase. And by all means explore Mars extensively before we're ready to go there... just don't waste a ton of money on symbolism; spend that money wisely.

    I don't think analogies apply here, this is nothing like Lindburg, this is so far beyond that.

    Even without resupply and a likely limited lifespan (say two years) I would do it.

    Face it, most of us will lead mundane 9 to 5 insignificant lives and will likely die a forgotten death lingering in a hospital bed. Why wouldn't you trade that for a chance to blaze a completely new trail for humanity, to truly go, where no one has gone before.

    I am sure there are a lot of scientist who trade the rest of their life for 2 years studying Mars in person.

    Besides that, he is talking about sending company, resupply etc.

    On top of that, this would be a volunteer mission. I don't quite get the nervous nellies who have a problem with someone else making this choice. It might not be for them, but they should at least be able to realize that for some this is an inspirational idea.

    I just can't believe the amount hand wringing over this.

    Though I think it is immediately clear that this will never be done because of the tender sensibilities of the public. If even the slashdot crowd are getting bent out of shape, the general public would frothing at the mouth.

    In fact, Mars has almost the same surface gravity on tiny Mercury (3.7 m/s/s for both), which is closer to the surface gravity on the moon (1.6 m/s/s/) than the surface gravity on Earth (9.8 m/s/s). You also need less than half the escape velocity to leave Mars' gravity well compared to Earth.

    Of those, only the escape velocity is actually relevant. The gravity at the surface is pretty much irrelevant. The escape velocity on Mars is twice that of the moon, which means it would take 4 times as much energy to leave Mars as it takes to leave the moon. That's in theory. In practise, it's more than that because you actually need more fuel to lift the extra fuel.

You're right, they don't equal being the first to walk on another planet... they're much better. The second doesn't even cost any money, let alone billions of dollars. Courage and vision are not the qualities of the man who launches himself into a suicide rocket to Mars, they are the qualities of men and women who do simple, good things on a daily basis. People who try to contribute positively to the world around them, and work to be better people every day. These kinds of people are very, very rare. In my opinion, we need do a seriously reappraisal of our ideals. I don't think the drive for conquest is a natural thing as some believe. I think it's simply a quality that man is capable of, that our culture, and cultures before us have worshipped. I understand the desire to GO there. I, like any other person, would love to stand on Mars and look up at the red, or possibly blue, sky, and think, I am standing on Mars! But for god's sake, let's do it when we are ready!! What's the rush? Being on Mars isn't going to solve any of the millions of problems that exist in our world today - not only simple things like hunger, disease, and war, but much trickier problems, like, how do we overcome the shortcomings of our own humanity?

    "Less than half" the escape velocity of Earth is STILL a considerable speed! Clearly I haven't done the math, but say you can cut your fuel requirements in half - you still have to haul all that fuel there, land softly enough that nothing is broken (or explodes), and THEN you have to have a way of dusting off safely. That's a lot of caveats.

    Why can't i have a video call facility from my LG Viewty (my carrier does not)?

    The past 8 years, corporate fungii has overgrown most government by atleast 75%.

    Bush and Cheney surely made sure corporates are in a position to sell US to highest bidder.
    Next we would see Statue of Liberty sold to France as a Derivative, while the Alaskan oil sands are already sold to BP and Exxon.

    I think Kennedy said it best, so I'll let his words speak for me:

    "We choose to go to the moon in this decade and do the other things, not because they are easy, but because they are hard... we shall send to the moon, 240,000 miles away from the control station in Houston, a giant rocket more than 300 feet tall, the length of this football field, made of new metal alloys, some of which have not yet been invented, capable of standing heat and stresses several times more than have ever been experienced, fitted together with a precision better than the finest watch, carrying all the equipment needed for propulsion, guidance, control, communications, food and survival, on an untried mission, to an unknown celestial body, and then return it safely to earth, re-entering the atmosphere at speeds of over 25,000 miles per hour, causing heat about half that of the temperature of the sun... and do all this, and do it right, and do it first before this decade is out--then we must be bold." http://www.quotesandsayings.com/sjfk.htm [quotesandsayings.com]

    Unless I'm misreading those words, sending a man to the moon in the sixties wasn't easy either, but we still managed to do it and bring everyone back safely. Sending a man or woman on a one-way mission to Mars in this century strikes me as a failure compared to Project Apollo's goals. I can't imagine any politician seriously supporting the plan. The mere idea of televising the journey seems barbaric to me. A one-way trip to Mars is clearly a death sentence to any astronaut willing to make the trip -- televising it feels like a particularly horrid version of reality TV, with a murder/suicide as the gruesome series finale. If that's our bold plan for the conquest of space in 2008, I'd feel better if we just stayed on Earth.

    There is a very real difference when it comes to risk. I remember a formula 1 racing driver from just after the war saying that it was quite acceptable to have a driver killed in every couple of races, after all they had beaten worse odds in the war and you have to die sometime. Imagine a sport with such odds of death today - nobody would allow it.

    Then there are wars where "hundreds" of casualties are seen as terrible. Of course for the individuals they are, but in previous conflicts you could lose thousands in a single battle, and if you made ground it was seen as a success.

    Of those, only the escape velocity is actually relevant. The gravity at the surface is pretty much irrelevant. The escape velocity on Mars is twice that of the moon, which means it would take 4 times as much energy to leave Mars as it takes to leave the moon. That's in theory. In practise, it's more than that because you actually need more fuel to lift the extra fuel.

    That depends on how many different ships there are. It'd be kinda silly to use the same ship to go from the surface of Mars directly to Earth. A scenario that makes more sense is this:

    1. Ship to get to Earth orbit from the surface
    2. Ship to get from Earth orbit to Mars orbit and back
    3. Ship to get from Mars orbit to Mars surface and
    4. Either a separate Mars surface to Mars orbit ship or the same orbit to surface ship from above

    That way you get to take advantage of more efficient ion engines (or something similar) on the long haul from Earth to Mars and back. Ion engines are efficient, but the acceleration is too low to get to orbit with them.

    The wars you're talking about are not like the wars back then. Let's face it: most don't care about wars like the ones in Rwanda where American or at least Western soldiers are not killed. There a genocide is seen as terrible, but only until Paris Hilton decides to expose her genitals on the very same news show. Those wars are being talked about by the 'intellectuals', but not by everyone.

    The other kind of wars, like the recent ones in Iraq, Afghanistan or Kosovo, where Western soldiers could die are where the public interest would actually last longer than one news show. That's because this kind of war is also fought for entirely different motives than those before: it's not about crushing your opponent, it's not about gaining territory. Sometimes nobody really knows what it's all about (like the last Iraq war). And that's where people at home actually care for the soldiers over there - and not for any other soldiers, but for their own. How many Iraqi soldiers left their life during the invasion? Do you know? Do you care? IIRC it was about a thousand more than lost their lives on September 11th 2001 in the Twin Towers. But somehow - even here in Europe - it seems that the only body count that's getting mentioned on mainstream news is the American one (I may be a bit wrong on that since I generally don't follow mainstream media...)

    I have nothing against great projects that hurt none, but "unifying the people of Earth" is horrible reason, which is not obvious at first glance. People of Earth are not one, they have different, legitimate, interests and priorities. You wouldn't like to be unified in Islam or in Chinese language, or in poverty with the rest of the world, would you? You wouldn't like the "unified world" to tell you how to live or who will rule you, or what laws to respect.

    IMHO, there already is too much group think and social (if not worse) pressure in the world as it is already. Unity for sake of unity (or engaging in an activity for the sake of unity) is nothing more then authoritarian dystopia. There is a good parable about it in William Golding's "The Lord of the Flies". Also, this kind of thinking often surfaces in investigations and court trials of cases of gang rape - majority of rapists in the gang didn't really wanted to hurt the victim, they "just held down" the victim and did it "because we were all together" (i.e. for the sake of group unity). I cannot continue citing examples of why that attitude is wrong (although widely accepted as good and encouraged) without introducing Godwin's Law, so I'll rest my case at this point. Unity is one of those "good intentions" paving the way...

    Whatever happened to exploring and dreaming? I would love to watch a televised mission to Mars, not for the bug under the microscope factor, but because it lets me dream that someday maybe we won't be confined to this little tiny rock in space and be able to spread across the stars. It would let me see the surface of another planet through the eyes of a human being, someone fully aware of the risks and consequences and willing to face them to share with the world something that no one has ever experienced before. A televised trip to Mars would give us tons of data that a robot cannot give, live analysis of the environment, what it feels like, smells like, tastes like (yes I know that you cannot live on your own in the environment, however the environment is bound to creep into where you live), looks like, how a Martian sunrise looks to the explorer, and so much more. How is that barbaric? Great explorers want to see something that no one else has seen before and share it with the world, that's not barbaric. It's inspiring.

    If there was a human on mars right now the rovers would have had their solar collectors wiped clean and that broken wheel either repaired or removed.

    What people obsessed with robotics forget is how limited a robot is compared to a human. Robots are fine when everything runs as expected, but when things fail, humans can adapt.

    We are getting to obsessed with safety, I wonder were the real men are, the men who stormed normandy in a hail of machine gun fire, who build wooden rafts and colonized the world.

    There are people who got what it takes, the same people that pushed the limits in other areas can do this. We as a society just need to give them the space to do it and stop forcing our own fears onto them. If there is someone willing to go and he/she isn't obviously unfit, then let them. I don't got what it takes, it isn't the no return part, it is the closed space I am sorry to say.

    The mission doesn't have to be a pure suicide run after all, sending enough supplies for one man to live years on mars is only a matter of cost. Just send a long string of simple supply runs so that enough will land close by and in tact to survive.

    It is a better deal then we many a person has faced in the past.

    The problem is the ethics of sending the volunteer. Too much of the public would find something inherently 'wrong' with sending a person on a known, one-way mission with no chance of coming back, and that lack of support would pretty much doom the effort.

    No, manned space missions are not foolish. The issue at hand is the great number of us who believe we need to get off this rock.

    If you just want scientific data and never want to move mankind in the stars. Then yes, ROBOTS are for you WAL-E!

    But many of us, believe that we need to move out.
    a) it protects our extinction from a catastrophic cosmic event
    b) it alleviates population issues

    Say the new world (Americas) were discovered today. Would it be foolish to send people over? Better to just send robots right? Well...only if you want nothing but pictures and soil samples. But if you want to expand, colonize...you send people.

    I think even the scantest review of history will show you to be wrong. Take Lindbergh, for example, crossing the Atlantic. That event took the world by storm in a way that hasn't been seen since the Apollo landings. There was a very real possibility that he wasn't going to make it, and he very nearly didn't. If it'd been an empty plane flying on autopilot, there would have been nothing like the interest or enthusiasm for crossing the Atlantic nonstop.

    Also, the statement that, "Robots do a radically better job for a tiny fraction of the price" is half wrong. They do a decent job for a tiny fraction of the price. The geological data the Apollo astronauts obtained in just a few days on the moon, for example, outstrips what we've yet gotten after years of probing Mars.

    I'd rather do the Greek Colonies [google.com] one way trip. Send excess population out into space to found colonies that will eventually trade with Mother Earth.

    Colonies might be easier on Earth, but the principle is the same. We just have higher start up costs and planning for space.

    I could easily see China doing this. The red planet might be Red.

    Firefly will probably turn out right...Mandarin and English will be the spoken languages in space.

    Also, I'm all for doing The Moon is a Harsh Mistress [wikipedia.org] i.e. sending prisoners out into space. Prisoners are usually are risk takers. I can think of nothing more rewarding and risky than founding new colonies in the long term.

    > 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.

    OK, in the long run, for purposes of exploration, yes perhaps a manned mission is reasonable. But in the short to mid term, it just seems pointless. There is still PLENTY of work for robots to do on Mars. Why not spend another 20 to 50 years on unmanned missions, which will naturally become ever more capable?

    In the mean time the Moon is a far better target for manned operations. It has a significantly LESS hostile environment (no atmosphere makes things a lot easier, 1/100th bar of CO2 is not doing anyone any good). The risks and costs are very much smaller, and there is a huge amount of science we can do. Not only that but much of the knowledge gained in manned operations on the Moon will be generally applicable to manned operations anywhere in the Solar System, including Mars. It may actually be CHEAPER in the long run to go back to the Moon first. Not only that but there are geopolitical reasons for establishing a presence on the Moon which may well virtually mandate going to the Moon anyway, so why not do it first?

    Furthermore there are, albeit tenuous, arguments for significant economic returns from Manned operations on the Moon. There are no such arguments re Mars and never will be. All a manned Mars expedition will accomplish is burning 100's of billions of $ on a program which will generate a PR event that, judging from our experiences with Apollo, will last 6 months, then the public will get bored with it, and the program will wither. No doubt some interesting science and engineering will come out of it, but it won't be worth the cost (100 billion $ easily represents 20-50 unmanned missions). Most of the same benefits in the mid to long term will also result from Lunar operations. There will be plenty of scientific benefits and the engineering knowledge gained will be essentially the same. On the other hand the risks and costs will be MUCH lower, maybe by an order of magnitude. Naturally we'll probably actually spend similar amounts on either program, but we'll get a lot more for those bucks on the Moon.

    Plus, as some NASA commentators have pointed out, the hardware required to go back to the Moon will be sufficient in general for accomplishing other valuable Manned missions, such as a near-Earth asteroid mission, or any other mission we can think of involving human spaceflight in the vicinity of Earth.

    Finally there is at least one direct argument for NOT setting foot on Mars. It will complicate the search for life there. No manned mission can ever be guaranteed not to result in some biological contamination of the Martian environment. Realistically it may not be much of a problem, but ANY signs of life discovered on Mars from that point forward will have to be evaluated in order to determine whether or not they resulted from contamination, however remote the possibility. Which just complicates that whole equation considerably. So it may even be inadvisable at this time to set foot on Mars.

    Forget Mars. It is a 'bridge too far' at this point. Give it 50 years. Maybe by then we'll have the type of spacecraft that are required for serious manned exploration of deep space, like say nuclear fusion powered VASIMER type rockets which can ferry back and forth multiple times with very large payloads and follow fast transfer orbits when carrying human crews. At that point the costs will be reduced vastly and it will make a lot more sense to go there. In 50 years it may be cheaper to go to Mars than it is to go to the Moon now, and in the mean time we can direct our limited funds to more sensible projects.

    Mars certainly is an emotionally compelling target, but it simply isn't a logical goal for manned spaceflight at this time, and logic trumps emotion. A logically sound space program is a good space program. One based on ill advised emotional arguments is not.
