Submission + - Tau Zero Takes Aim at Interstellar Propulsion (discovery.com)
astroengine writes: "Could the future of interstellar space travel be in the hands of a group of volunteer scientists? According to Paul Gilster, of Centauri Dreams fame, interstellar propulsion techniques, by their design, will require an incremental approach, headed not by governments, but by private enterprise. And don't expect to reach the nearest star any time soon, that could take centuries! So you think striving toward interstellar spaceflight is a little "far out"? Not so fast. The Tau Zero Foundation is already on the case and has just completed year one of the five year Project Icarus study, just one project that will hopefully carry mankind beyond our solar system."
