Stephen Hawking Helps Launch Starshot | Why Mars Matters | Universe Simulation

Stephen Hawking Helps Launch Project 'Starshot' to Send Interstellar Probes to Alpha Centauri Breakthrough Starshot is a $100 million research and engineering project to prove that a tiny postage stamp-size craft propelled by a laser sail could reach the nearby Alpha Centauri star system in a 20-year trip.   'Starshot' Interstellar Probes May Hunt for Alien Life Close to Home Alpha Centauri and other star systems aren't the only targets for the interstellar Breakthrough Starshot project. See how the tiny probes could reach Pluto in just three days and revolutionize how we explore the solar system.
