Sci-fi author Charlie Jane Anders wanted to give us an idea of what life would be like on a tidally locked world, a planet orbiting so close to its star that it can’t rotate around its axis, in an article for The Atlantic. Unfortunately, it turned out to be less of a dissection of a hypothetical colony on a completely alien world, and more of a stealthy ad for her science fiction novel, which... really, who’d do something like that? (Me, actually. I would do that.) In the interest of providing a more or less realistic answer, we’re going to talk about how astronauts would cope with spending their lives in permanent twilight of one of the most common types of terrestrial planets out there.
