Mann works with a stripped down tree branch to use as material that will become an aid to help sustain her for three days in the wilderness. As the first phase of their extensive training program along the way to become full-fledged astronauts, eight new candidates spent three days in the wild participating in their land survival training, near Rangeley, Maine.
