I just pulled this one out of my email drafts folder.

“Dream of solar sailing in space lives on in new project” discusses an announcement by The Planetary Society to build, launch, and test LightSail-1 — a small craft that will be propelled by solar sail. As explained in the article, previous attempts to launch solar sail craft failed.

I have always been intrigued by the solar sail concept (I am intrigued by a lot of things, though) and will try to keep an eye on this.
