I earnestly couldn't believe my eyes, but I stumbled over Zuke696's youtube profile, while watching "Moon Machines". (* Thanks to Thruthiness by the way for this collection. *)

Zuke696's playlist folder is a brimful collection of the finest and most interesting documentations about Space, Space Travelling, Astronomy, Science, near future technologies etc. ... etc.

Watch it, while it's online.

Nice find Scifan. I've watched a number of the videos listed in the playlist folder, and they are indeed some of the better science documentaries around.
Thanks
