What are the primary medical and health problems and issues Involved with Space Colonization?
Well, the second half of your question is easier to answer — these problems haven’t been solved yet, and they are of great concern to the folks at NASA and the ESA (yes, I know there are other nations and organizations working on space travel, but most of them are still working on getting into orbit for more than a few hours) If you’re talking about simply travelling to the moon or Mars and setting up a colony (one-way trip, in other words), then the G-forces you’re worried about are only really experienced during launch, and to a lesser extent during the burn to slow down for re-entry. Really, the problems that keep mission control specialists up at night are bone density loss from lack of resistance in microgravity (the latest data show that each month spent in near zero-G lowers bone density by 10%, meaning you’ll be quasi-osteoporotic by the time you get to Mars and back), constant radiation exposure from the sun and cosmic radiation (not to mention if you get caught in a solar fl
