Making Mars habitable for humans.
There are a few major problems with people starting life on other planets, namely the planets themselves. Mars is cold, has little to no atmosphere and no useable water currently. People suggest just starting a massive greenhouse effect, by releasing the huge amounts of CO2 trapped in the planet. That theory is fine, but Mars has an atmosphere that does not trap it's gasses very well, because there is no magnetic field to block solar winds from blasting away the newly released CO2, so we need to block those solar rays somehow. Digging to the core of Mars and starting a core reaction seems very difficult to do. I say that the easiest way to create the required magnetic shields would to set in orbit a bunch of spinning magnets with copper wire wrapped around them. They are pretty easy to get spinning and will perpetually spin, because space has no gravity or air. You could also set up solar shields that block the winds, but allow the light to come through focusing on the areas where the frozen CO2/H20 is stored. Once plants are introduced, it should be a relatively quick process to see certain oasis areas pop up that would allow humans to set up camp around. The tempratures will be cold for a while, but eventually raise to the point where all the water is released. We would not see this in our lifetime, but it's not far fetched to think that a couple hundred years from now our great great great great grandkids could take a vacation. The moon has helium 3 for fusion power, that could be transported to Mars for power sources, since we'd need ways to power essential devices. The moon's low gravity and craters would make great space bases that could be a stepping stone for travel to Mars. It would also lessen the need to travel in heavy/expensive rockets. Just a few ideas. It's either my way, or people living in boring domes.
