http://www.nasa.gov/centers/glenn/research/warp/warp.html [Broken]Have you ever wondered when we will be able to travel to distant stars as easily as in science fiction stories? NASA Glenn's Marc Millis (pictured above), who has taken a break from Project Management for NASA's Breakthrough Propulsion Physics (BPP) Project to return to conducting research, offers this assessment of the prospects for achieving the propulsion breakthroughs that would enable such far-future visions of interstellar travel.
This web site focuses on the propulsion related issues, explaining the challenges of interstellar travel, existing propulsion ideas, and the possibilities emerging from scientific literature that may one day provide the desired breakthroughs. To simplify the presentation for the general public, analogies to familiar science fiction are used. This site is intended for public audiences, whereas researchers might want to check out the Breakthrough Propulsion Physics Project web site.
