When I first saw "NanoSail," I thought the sail would be a large device for collecting light samples or heating or something like that. When I read on and realize it was actually a solar wind-driven spacecraft, I was blown away! It was so amazing that the sail spontaneously unfurled itself, it's almost suspicious. The NanoSail D is more than just the plaything of a group of NASA engineers; solar sail technology could be used in the future to slow down descents of satellites and reduce space debris.
