Micro-spaceships of only a single gram could be propelled at a third the speed of light toward nearby stars. They would be shoved, as tiny lightsails, by powerful external lasers. Accelerating for only ten minutes each would allow tens of thousands to be launched every year. A great cloud of micro-spaceships could then expand in every direction from our solar system to explore all the nearby stars and their potential exoplanets. Arriving for their thousands of flybys after 13 to 20 years--what an astounding leap forward in scientific understanding they would provide.

Dr. Philip Lubin is a Professor of Physics at the University of California, Santa Barbara. He is a NASA Institute for Advanced Concepts Fellow for his work on laser beamed energy micro-spaceships.
