Solar Sails - Science Fact Before Fiction

Further to my post about solar sails, it seems it was science before it was science fiction. I found this letter on the Register.

One teeeny, pedantic point is that my father, Prof. Maurice Cohen, wrote a paper in 1959 showing that a solar sail powered orbital device could break earth orbit eventually. That was of course assuming the properties and characteristics of materials and technology appropriate to the age.

So I'd have to say that has been the stuff of science, as opposed to science fiction, longer than most people realise :)

Jeremy Cohen.

Big respect to Prof Cohen.
