The Moon and Mercury - Is There Something Similar?

Mercury is tilted less than a degree off of the orbit around the sun. So you don't need very much of a crater to have a permanently shattered region. There's water that has been found through radar returns, within those permanently shattered regions. The temperatures are completely reasonable for machinery to exist at the poles. Some science fiction writers even imagined a domed cities on massive tracks that simply moved just out of the sunlight as the world rotated.
