Setting Sail In The Sun
Moffett Field CA (SPX) Sep 03, 2010 - By rigging large pieces of cloth atop boats, early explorers harnessed the wind to voyage across oceans. Now, modern space explorers want to use sails to send spacecraft to the far reaches of the solar system and beyond. These sails will be made of large, ultra-thin gossamer plastic sheets that, instead of wind, will be propelled using sunlight.
