                  Scientists Testing Space Propulsion by Light

   by George Putic

   Can the sun - the heart of our solar system - power a spacecraft to the
   edge of our solar system? The answer may come from a just-launched
   small satellite designed to test the efficiency of solar sail
   propulsion. Once deployed, its large sail will catch the so-called
   solar wind and slowly reach what scientists hope to be substantial
   speed. VOA's George Putic reports.
