This is the story of a brave astronaut. He was checking out an interesting crater that was quite some distance from the landing site.

Then the crater collapsed. Our lone astronaut fell into a cavern, and was just barely able to send a signal to be rescued.

Not sure if the signal made it past the walls, he paused for a moment and looked around: it is actually incredibly beautiful in here.
