Former NASA Astronaut Mike Massimino is back to serve as our tour guide through the universe in the new season of THE PLANETS AND BEYOND. Each of the eight episodes in the second season takes an in-depth look at everything from Neptune & Uranus, to alien planets and the Sun. Massimino, who flew on two space shuttle missions to repair the Hubble Telescope, provides a perspective on the cosmos that only an elite few can match.
