Through the eyes of astronauts, entrepreneurs, and inventors, host Emily Calandrelli asks one of the key questions of Outer Space: Why do we explore? We’ll hear from several astronauts and visit a few locations where the most powerful observatory is being built— The James Webb Space Telescope. Plus, we’ll meet a man with a unique goal of building a human settlement on the planet Mars. There’s only one catch: if you go, you can’t come back.
