We come to rest at the bottom of the crater, and see something amazing!

During the long night everything was hundreds of degrees below zero. Some gases turn liquid at that temperature, and others may be trapped in mud in ways we don't understand. But when the sun returns, the gases evaporates, creating a thin atmosphere in the crater bottom! There's a pale blue haze around - from above it must be a weird blue area of the moon!

There must be rich nutrients in the mud, because we see something incredible: many of the stones are in fact frozen seeds: they split open when sunlight warms them! Plants have only twenty seven days of sunlight before the sub zero vacuum returns, so they grow at an incredible rate: an inch every few minutes!

That settles the question! I want to go outside! Or... should we do something else?
