Scientists Propose One-Way Trips To Mars
vortex2.71 writes "Invoking the spirit of Star Trek in a scholarly article entitled 'To Boldly Go,' two scientists contend human travel to Mars could happen much more quickly and cheaply if the missions are made one-way. They argue that it would be little different from early settlers to North America, who left Europe with little expectation of return. 'The main point is to get Mars exploration moving,' said Dirk Schulze-Makuch of Washington State University, who wrote the article in the latest Journal of Cosmology with Paul Davies of Arizona State University. The colleagues state — in one of 55 articles in the issue devoted to exploring Mars — that humans must begin colonizing another planet as a hedge against a catastrophe on Earth."
At least they could breathe and had water when the colonized America.
This is blinging
Three years ago I would have happily signed up for such an adventure, even if it was one-way. To be part of that, oh wow. These days, with a wife and a child, I guess I'll envy those who go, but wont be amongst them.
So I dont thinnk there be volunteers lacking, Even though I dont know wether they ft the general requirements of mental stability to be locked up in a can for a year. Even the early colonists of the Americas expected to make some money and then return. And even in the Americas it was a three month voyage on a ship, not a year in space.
But hell, what a ride.

... the chinese most certainly will.
I run: Windows, OS X, Linux, FreeBSD. Just because you have a hammer, doesn't mean everything is a nail.
It's not unethical if they volunteer for it. I won't touch the cloning thing though, seems a bit off-topic.
Not really the kind of people we want to use to seed life on another planet. Perhaps they could set up the first colony on the Sun instead...
Yeah, as it will already be hard enough to keep normal people psychologically stable all the way there, and from throwing each other out of the airlock, let's send criminals and crazies :) I don't think they will even arrive there. You could just as well shoot them on-spot.
It's not going to happen. At least not in the western world. The US space program is highly political. NASA requires the good will of the congress. Since it would not be politically favourable to send people on a one way mission, NASA would never get funding for it.
When our name is on the back of your car, we're behind you all the way!
If you're seeding technological infrastructure, why send people at all? Send ships of robots and parts, once the robots have assembled the habitat, pressurized it, prepared gardens, located water and what not, then you send people to live there.
If I have been able to see further than others, it is because I bought a pair of binoculars.
"that humans must begin colonizing another planet as a hedge against a catastrophe on Earth"
I wonder what fraction of the populace cares about the continuation of the human race. Do you? If a rogue planet were to one day pass through our solar system and smash earth on its way by, would you care about colonists on Mars continuing our culture and genetics? If you do care, why? If not, why not?

That treaty won't be worth the paper it is printed on once some entity that has enough resources to defend its property rights actually makes a large investment in space.
There is no shortage of land on Earth. Canada alone could comfortably fit billions, assuming they don't mind living in a periodically cold, hostile environment that is still infinitely friendlier than that of Mars.
First you need to design the robots that can do that either unsupervised or can do it supervised by a 45 minute time delay. Even controlling something as simple as the rovers over this distance is hard - imagine trying to control complex assembly robots. It makes sense to do this for the moon, where you only have a 1 second control latency to worry about. Not so much for Mars until our robots are a lot more smart.

... nor are there any economically exploitable resources. Geez, I get so tired of this - otherwise intelligent people spouting nonsense about colonizing other planets. What, for example, are these colonists going to do for a living? Bear in mind that Mars is effectively made of rust and silica, that shipping stuff to Mars is ludicrously expensive, and that even the most basic needs for life (air, water, food, shelter) are not available on Mars without a lot of equipment to process them. Also bear in mind that there is no market for any product on Mars, so whatever you make would have to be shipped back to Earth to be sold - and what imaginable product could you sell at a profit? This project would have a gigantic up-front cost with no realistic hope of any payoff. Who's going to invest in something like this?
And the "we need a colony to preserve the human race in the event of disaster" doesn't hold either, due at least in part to tragedy of the commons issues. At most, very, very few people would be able to be transported to Mars - meaning that neither I nor any of my direct descendants are very likely to personally benefit. So why would I be interested in expending enormous amounts of tax dollars on this? Additionally, it would be a lot cheaper to safeguard the earth (which is a lot more hospitable to life than Mars will ever be) against looming disasters, than to try to establish colonies on other planets.
Sure, colonization of the solar system is a cool idea - so why haven't plans gotten off the ground? There's no money in it.
Yesterday was Remembrance Sunday here. If we have in the past and can continue to send people to war with a realistic chance that they'll die, then what's the issue with sending someone on such a noble endeavour as this. At least they will know their lives advanced all of humanity, instead of advancing a few inches into no man's land or paying the ultimate price for the enrichment of a few billionaires arguing over resources.
If humans screw up the earth to the point where it becomes unlivable, our species deserves to just become extinct.

There is inferior bacteria on the interior of your posterior.
The martian atmosphere is already 95% CO2. It's as warm as it's going to get. Furthermore, the martian atmosphereic pressure (at its lowest elevation) is only 3% of Earth's atmostphere (at sea level). Mars simply is not terraformable. It lacks the gravity and a magnetosphere requried to support an adequate atmosphere. You might be able to establish a colony of photosynthesizing bacteria or even some very rugged desert plants and let that run for a few millenia and see what happens. Anyone who thinks it is remotely possible to colonize Mars doesn't know shit about Mars.
"humans must begin colonizing another planet as a hedge against a catastrophe on Earth" For the love of G-d and all that is holy, why must we? If we have the technology to make Mars habitable, then we have the technology to fix Earth. If the Earth goes to hell in a handbasket, would humans living on Mars save your life? Why not spend 1/10th that same energy to fixing this place? If we can't straighten out our own house, what the hell makes us think we could make Mars work out? Such a trip would be nothing more than billions upon billions of dollars, pulled from the taxes of hundreds of millions of people, just to pander to the selfish dreams of a very small number of people. Spend that money on making a light rail system spanning the US, clean energy sources (solar, wind, etc), and you'll have lots left over; and then it helps save this planet, for the benefit of billions of current earthlings, plus all generations to come. Or...spend the money to send a couple dozen people to Mars, so they can...do jack for the rest of us. One key thing to keep in mind - most of the people who went from Europe to the US back in the day either paid their own way, or were sent specifically so they could gather resources to send back. The idea that it was a one-way trip is true only for the people who paid their own way. So if a few billionaires want to get together and send themselves to Mars, I'm not going to stop them. But why the hell should I pay for someone else to go?
Canada? Sorry no vacancies. I prefer cold and hostile over crowded and polluted. And we'll keep our fresh water to ourselves (and our closest neighbours), thanks.
Yes you could find people willing to go on a one-way trip. Even people who are qualified. Sure.
But I don't see the point in sending anyone until we've done enough robotic exploration, excavation, processing, manufacturing, and assembly where there would already be pre-constructed habitats and stores of fuel.
And once you've got a pre-established mechanized facility for people to arrive at, I see no reason not to just wait a little longer until the fuel stores are larger, and a return trip is feasible.
I'm 100% for manned exploration. But I think the time when the only possible human exploration is of the one-way-trip variety and the time when we are far better served by robotic exploration are largely the same.
I mean we aren't talking visiting other solar systems here which may necessarily be one-way. If we can't bring people back from Mars then it's due to a serious lack of technical capability and resources. So, let's use robots until we've fixed the capability issue, and use the robots themselves to fix the resource issue.

But I also believe that it matters less how many years you live than what you do with the time you have, however long that may be. My family may not agree of course.
Don't get me wrong; I fully expect to do something interesting and useful in my 60s and 70s, health permitting. But I don't fear death; we'll all go some day. I'd rather go out doing something that would really make a difference to how mankind sees itself, and which just might sow the seeds of a new world.
Why is it in our collective interests? What benefit is there to be had from the continuation of the species, aside from the satisfaction of our individual instincts? It would be neat if humanity became a galactic empire, but it would not be an inherently superior condition to what we have now. More people are not necessarily better.
