Solar sails have featured in various sci-fi mediums for a good while now, but NASA are planning to make the technology a reality in a mission which could launch as early as the 29th of July. An earlier 2005 launch of a solar sail craft by The Planetary Society was deemed unsuccessful, so if NASA's experiment fairs better it could be the first step to enabling space exploration powered by the sun's energy. The solar sail, dubbed the NanoSail-D is made up of aluminium and space age plastic and measures 100 square feet when unfurled. A sail of that size isn't enough to carry a craft of any significant size, but sails of thousands of square feet could open up some interesting possibilities. In theory, solar sails would be a better choice than conventional rockets for longer missions.
