As most of you probably know, the concept behind Dooku's solar sailer is based on modern scientific theory, and not a galaxy far, far away. I was thumbing through my old Star Wars Question and Answer Book About Space (1978), and came across this image of a solar sail. I thought it might be of interest to everyone. Other highlights of the book include discussion of the planned "Space Telescope" that will be launched in 1983 (which we all know and love as Hubble). (aka as the "We had the stupid thing out of focus for 15 years, don't we feel like @$$es" telescope). The author (a professor) also predicts that the first astronauts to explore Mars will actually be robots, which has come to pass, albeit none too successfully.
