Space sail could bring used rockets back to Earth

GordonCopestake writes: An article from New Scientist proposes that all new space craft have sails attached to bring them back to earth to reduce the amount of garbage in space. From the article: "The risk to spacecraft from a collision with space debris could be reduced by equipping launchers with a gossamer-thin "sail". The idea is to deploy the sail after the rocket has released its payload to amplify the drag of the last vestiges of the atmosphere, and so force the rocket out of orbit." Interesting idea and would boost the research on sails which could then be used for inter-planetary travel and possibly even interstellar travel.
