About Colony Mars:
This is a sci-fi series set in a human colony on Mars. The science depicted is, for the most part, plausible. In other words, what’s technically possible with either current technology or taking experimental research a step or two further. That said, you won’t need a calculator or a slide-rule to enjoy the story.
