Great find, I needed some good news to drown out the bad in the world. I'm all for the generation ship, drones as well. We need to bombard those Gliesians with radios, lights, and drones right away so when we eventually meet we can win the we saw you first argument. Now if only we could reach anywhere near the speed of light...

Heck if we send a ship now, by the time it reaches there I wouldn't doubt our having technology that could get there in a single lifetime. Our future spaceclowns will probably think the inbred offspring on the generation ship as the victims of a bunch of suckers as they whizz by us, probably mooning us as well.
