Miranda

"'Miranda is a relatively unimpressive moon, a small body made mostly of water ice, but it does have one incredible feature: the single tallest cliff in the entire solar system, a sheer drop of over five kilometers. With the right equipment and Miranda's low gravity, a base jumper would be falling for almost 20 minutes before they reached the ground.""Hominizing Miranda will be difficult, but for such a tiny moon so far away from the Sun, we've already got an extensive waiting list of potential settlers. Start building Habs, and you'll be guaranteed to fill them.'"
