Who’s visiting who? This chart of solar system exploration shows every robotic space probe currently exploring (or about to explore) a major solar system object… except for the Earth and Sun of course, because there are way to many of those to show on one chart.
So you wantto be an astronut : must be educated and be skilled, under-go rigirous training, a very long and nasty ride to get anywhere. Not to mention the dangerous exposure to hard radiation for up to a year or two. Once you arrive, you will spend the rest of your life, inside something like you see below. Oh yes, did I mention, you will have to get along with the same people, eat the same food, have the same routine, until you die and in space no one can hear your screams. Good luck.

Lockheed Martin and Surrey Satellite Technology Ltd. were awarded contracts to study and develop concepts for a Mars lander and a data link satellite, respectively, for a 2018 exploratory mission. If that mission is successful, Mars One hopes to begin a human colony on Mars by 2025. The lander, based on Lockheed's successful Phoenix spacecraft, and satellite would each test technologies needed to sustain human life on another planet.
