On a mountain on Mars, a 'doorway' has been found. Natural feature, of course, "boring old wind erosion" or something.
It's not exactly the 'Red Planet' anymore, is it?
A planet of extremes, is home to the largest mountain in the solar system, the largest canyon in the solar system and intensely severe dust storms. It is also home to the only other likely option for humans to live within our Solar System.In the next two decades, if not sooner, humans will leave Earth for Mars, knowing they will never come home again. That they will live the rest of their days on another planet. In a bubble, obviously.
