Sails of the Sun Solar sails are one of the promising ideas for propelling robotic probes to distant stars. These use the gentle pressure of light from the Sun to move themselves. Information on these solar sails can be accessed at Another candidate for propelling such long distance interstellar voyages is the fusion propulsion technique. Access more information on fusion propulsion at http:/ neep602.lecture31.fusionProp. 96.html.
Warp five, Scottie In case you are wondering why it is taking science so long to develop a spacecraft that can "hop" galaxies in an afternoon, the National Aeronautics and Space Administration (NASA) has put up a few Web pages at PAO/warp.htm called "Warp Drive When?" Scientists from NASA's Breakthrough Propulsion Physics explain the problems they currently face in the development of warp drives and also speculate on possible solutions.
Rocket in your backyard If you ever wanted to build your own rocket and zoom to outer space, then http:/ is the Website you should be looking at. The page lists all the vital properties to look out for in your building materials. The Websites of the Interstellar Propulsion Society (at http:/ and the First Millennial Foundation (at http:/ can also prove helpful before you pick up your hammer and nails.
