So, the argument is let's not go to Mars because we'd have to deal with cosmic rays. Instead, let's go to Titan, which has an atmosphere, but is ridiculously cold and rains methane. Also, we can't go there because it's nearly thirty times the distance. Plus we'd still have to deal with cosmic rays along the way. I'm not convinced.

Still trying to figure out why under the moon surface isn't an open topic for these guys. From there you could go to anywhere else. Other than travel time, the risks of Titan and Mars voyages should be the same, yes? Neither one has a realistic rescue option for the stay or duration of trip

The surface of the moon is dramatically more hostile than the surface of Mars by every metric, and it's almost as hard to get to the moon as it is to get to Mars. Building a long term permanent colony on the moon would be far more difficult than doing so on Mars.

As long as you can manage the travel, Mars is by far the more desirable target for colonization, both short term and long term. Elon Musk believes that his ITS can cut travel time down to 2-3 months, which seems reasonable, even if your craft's shielding isn't the greatest.

This is silly. First we should build orbiting colonies, some that can fairy between the moon, mars and eventually other planets (I believe these are often called Cyclers). Solving the living condition issues in these colonies is actually easy -- they would be large rotating cylinders to provide artificial gravity (probably 1/2 g) and the outer perimeters would be water containment which is very good at blocking cosmic rays. A strong magnetic core could also provide some shielding.

Hopefully we can develop some light materials for radiation protection. So we can have radiation-proof domes and suits on Mars.

The trouble there is that, in order to attenuate high-energy radiation like the cosmic rays under discussion, you need something that's either extremely dense or extremely thick, and ideally both - dense so a speeding particle is more likely to hit it instead of zipping past between the atoms, thick so that Bremsstrahlung X-rays get absorbed before they reach human tissue susceptible to ionization injury. Both of the…

I'm completely out of my depth here, but couldn't we develop some kind of force field to do this? I'm thinking something along the lines of a Faraday cage, but for the GCRs.

Is anyone researching this line of thought?

Finding solution is not a problem, human nature is a problem. > stop eating animal-based foods Good luck with that. Sad true is that people don't want to change their life style. If you ask them for solution they will tell you exactly the same thing as you wrote, but most of them will not implement any of this solutions in their life. They want to eat meat, they want to consume, look at global warming, everyone know…

People want to live a comfortable life and they'll give up with natural meat if they'll be given good artifical alternative (especially, with genetically identical alternative). Green energy, effective water recycling, disposable packing materials and automatic sorting and processing of garbage are the things that, given the adequate technology, can make the sustainable life style smooth and easy. We don't need to ch…

The effort to make existing life sustainable could be spent making life more comfortable, slapping an excuse for caring the environment on the way. Meat can be improved by giving them more land and organic food sources, car transportation can be improved by a better designed electric cars, and that's what we are getting, instead of research into artificial meats(which do exist in an inferior state) or improvements to public transportation (public transport in many cities is neglected).

One could always go back to a life of eating meat once a week, riding bicycle to and from work, living in a developing country with broadband internet, electricity and clean water and thereby remove almost completely their carbon footprint, but who is in the mood for that, let's make life more innovative and even more comfortable than before, while telling ourselves these innovations are for the environment also! We eat organic and drive electric and pay $1000 a month for health insurance! Go us!

I think that the pursuit of knowledge is a really good way to spend your time, but I do not like when simple solutions to real problems are sidelined in favor of the latest buzzword-oriented technology fetish. In times when the president-elect has announced that he is shutting down NASA's climate change research, ostensibly to fund space exploration, I think we need to remind ourselves that any work we chose to pursu…

I think we should colonize other planets because we can. Not as a solution to any problem. I will defer to The West Wing to explain: https://www.youtube.com/watch?v=9yUHnERJ0zs

OK, you had me at "because we can" :)

I think that, before colonizing other planets, we should start by realizing that Earth can easily sustain human kind for the foreseeable future, given some pretty modest tweaks to our way of life (compared to "going multi-planetary" that is). If we start valuing quality over novelty, stop eating animal-based foods and re-organize to live closer to where we work, we can stop the consumption and that is taxing our ecos…

Nuclear stockpiles (and MAD) arguably reduce the number and likelihood of military conflicts. If it wasn't for nuclear weapons, we would've had third world war, possibly dwarfing the second in terms of casualties and destruction similarly as the second dwarfed the first.

Do you seriously think that any of the following global political challenges:

- convince everyone on Earth to implement changes that are bad for them, like not eating animal-based foods, with only the promise of "maybe in 200 years your descendants, should your line not be extinct by then, will benefit" as compensation

- reorganise every single human settlement and/or social structure on Earth to put people closer to their workplaces

- implement a global wealth redistribution scheme that doesn't start with North Korea conquering the planet through nuclear war

- successfully convince every NWS to destroy their nukes and institute a worldwide ban on nuclear weaponry

Are easier than the engineering challenge of building a colony on Titan? If yes, please let me into whatever politics-free, single world government utopia you're living in.

You keep alluding to some cataclysm but that's not enough to make your point count to say you have some paper in the works.

How about we do both?

I don't think anyone is suggesting we stop taking care of the planet and just find a new home to exploit once the Earth is used up. All we're saying is that we want to explore, colonize and seek out new places. It's what human's do, and it's good for our survival as a species to become an interplanetary species. I'm sure we can do that and take are of Earth at the same time.
