"In 2069, if all goes according to plan, NASA could launch a spacecraft bound to
escape our solar system and visit our next-door neighbors in space, the three-star
Alpha Centauri system, according to a mission concept presented last week at the
annual conference of the American Geophysical Union and reported by New Scientist.
The mission, which is pegged to the 100th anniversary of the moon landing, would
also involve traveling at one-tenth the speed of light."
