Powered By Space: Reinventing Spaceflight

Dr. Ben Longmier and other scientists journey into the Alaskan wilderness as part of a quest to build a whole new type of rocket engine. They're here to launch rocket components into radiation-filled environments of space. Their idea is to use the energy of the fourth state of matter, plasma, to revolutionize space travel to Mars, the Moon, asteroids, and other targets within our Solar System.
