Re: Mars
@rhubarbjackson- Well, the International Space Station has to deal with -255 degrees on one side of the earth and +250 on the other side. We've got people floating there right now. So I think NASA has handled the space heater problem. :)

As for the radion and charged particles, I mentioned that in the article as an obstacle to overcome. The ISS is subject to them now and uses a combination of shielding and rotation to minimize the exposure. Longer flights will require more advances.

But isn't that a good thing we work on problems like these? While the earth's atmosphere protects us from many of the dangerous particles, we create some ourselves and put ourselves in danger. We also have hurt our own atmosphere and changed what types of radiation gets through in places. What if we continue to do that? Also, if we ever have any intention of doing anything in space ever, this is a problem to solve.

As i mentioned in the article, nearly everything we've learned to do in space has had a profound and lasting impact on earth. Check out the list of things NASA has gifted to the world. It really does show how space travel does in fact mean "investing in resources down here."

At any rate, yes, that's still a problem we're working on. so is a propulsion system to make the trip. Also, spacesuits need to get better. There are all sorts of steps left. Thanksfully, we've got people working on them. But these were two steps that brought us a little closer.

Last time I checked, the temperature on Mars was minus 200 degrees F.  Better bring some space heaters.  Lol.  Also Mars has no magnetic field, so anyone that does happen to make it there will have to contend with waves of charged particles bombarding them on a regular basis and mutating their DNA.  Sorry to burst your bubble.  Let's focus our resources on taking care of our own planet, the one that we can actually live on.
