There are still a lot of puzzle pieces missing to make a possible colonization of the moon or Mars one day possible. In the meantime, however, pioneering action follows pioneering action. This year alone there was the first motorized flight on a foreign planet and the extraction of oxygen from the atmosphere of the Red Planet, which consists of 96 percent carbon dioxide. So it is high time to think about future housing, in case we one day want to send a few people up for research purposes or are even forced to leave our current habitat.
