We need to get off of this godforsaken planet, and terraform Mars. This is being slowed very much by politicians and ignorant people who do not understand the importance of the survival of the human race. We have to change that or all die in a large explosion of some sort. Please post any ideas you have to accellerate the colonization of Mars and/or informing ignorant people. I was thinking, lead weighs a lot but is a very good radiation stopper. To defeat the cost of getting it in orbit, we could shoot it out of one of those gigantic satellite guns we used to have and just manufacture the space ship in orbit.
