NASAs space telescopes are exploring the universe and searching for habitable planets out among the stars. Missions like Kepler and Spitzer are combing through our galaxy for Earth-like planets, while telescopes like Hubble and Chandra are delving deep into the evolution of the universe. Professor Hawkings theories have unlocked a universe of possibilities that NASA and the world are exploring hand in hand. Astronauts Rick Mastracchio and Koichi Wakata aboard the International Space Station (ISS) spoke with Professor Hawking during their mission earlier this year. These excerpts courtesy of Arrow Media.
