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."

C'mon - comparing flying a single person to Mars with no chance of coming back is like Lindburgh flying to Paris??? Is he saying that Mars is populated with (to quote the Simpsons) cheese-eating surrender monkeys? 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.
This article is *really* poorly thought out.

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.

Mars is a much shorter trip than Magellan's (Score:5, Insightful)
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.

Yeah, I wouldn't be surprised if another culture will do it, and I wouldn't be surprised if they do it as a return trip.
Other propulsions systems could make a round trip feasible by allowing solar powered launch. A culture that believes big, loud, exciting rockets are the only way to lift things into orbit, that will not commit any funding to alternative designs which work in computer simulations and have been around since the late nineteen eighties while supporting development of further rocket technology, that culture will fail to go much beyond the moon return.
To take the canoe example, do you think the Polynesians powered their canoes by facing backward and throwing shit overboard?

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.

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. It ridiculous to associate him with this insane proposal.

- Nukes is about our best bet. Sadly, ppl fight that. But the Japaneses system that is designed to support 10-100 MW would be ideal (20 MW, for 30+ years).
- Solar being beamed. A simple power sat above that beams down the energy. Probably not a bad way to disribute power around the planet, but I would not want to depend on it.
- Geo-thermal. There is some very good indication that there is heat close to the surface in several areas. That could change everything. Provide clean power and heat. I would still prefer the above as well.
Once we have energy there, it is easy to have robots build. Even a remote control arm can work at burying several Bigelow systems. Once buried AND a garden is started for food, then we are good to go. There is no doubt that many ppl would volunteer. I know that If I were younger, I would.BTW, one weird idea would be to send a bunch of women and have them serve as incubators. In particular, if we send several missions of women AND zygotes, then we can grow a colony there. It may be a lot cheap approach to guarantee bio-diversity. In fact, I would think that once we have several small groups there, that we should send not just human zygotes, but also seeds and a number of animal zygotes. it would be useful for just in case.

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.

Nobody else seems to be reading between the lines here. The person who accepts this mission is going to Mars to die. Whatever happens.
We normally pick young, fit astronauts with their whole lives ahead of them. This proposed mission is philosophically profound and does have the potential to unite the world in a way that the original Moon landing did. The suggestion is a piece of genius!
Getting to Mars is very difficult, but a return mission is bordering on impossible right now. So we pick a mature (read old), experienced astronaut who may be facing their last years and send them on the last and ultimate journey of a lifetime. The symbolism is not pointless, it is a statement of human fragility and mortality combined with enormous potential and sacrifice.
If the first (and possibly last) man on Mars isn't top TV ratings I don't know what would be.

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.

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?

No, they don't. Please read up on what "sterilize" means and stop spreading misinformation.
Oh, heck, you probably would have done it by now if you were going to.
Sterilize = kill ALL bacteria. You can put something that has been sterilized in your bloodstream and not get direct infection or exposure to bacteria.
Sanitize = kill bacterial to a certain threshold or standard, or kill harmful bacteria. You can lick something that has been sanitized and probably not get sick. However, if you cultured that hospital toilet seat, you can be sure you'd get bacteria.
Bioload reduction = "We're pretty much sure that it is not covered in stool or loads of harmful bacteria, but beyond that can't say."
It is almost impossible to build something the size of Mars rovers and have it be STERILE. Anything exposed to general atmosphere for over 20 seconds or so is no longer sterile. Even in the O.R. (which has special filters and a non-recirculating atmosphere) things exposed to the air for prolonged period are considered unsterile. If any of you guys worked in a bio lab, open up a can of L.B. broth, and walk away. After 20 minutes, recap it. What happens?
I really appreciate whoever sent me the planetary protection link, and it confirmed what I thought. We are *very* concerned about bringing foreign / alien bacteria here, but it is just about impossible to keep us from spreading our own throughout the universe.

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.
