I'm trying to identify a book or short story I read at least 10 years ago. The bits I remember are that it was some kind of sci-fi story about a journey to another star. The star was probably Alpha Centauri. It was expected to be a very slow journey taking many years. [more inside]

When I was a kid, my local library had a great selection of illustrated books focusing on the hypothectical future of space travel, life in space stations, space craft, planetary exploration. Some were pretty far out, but the most memorable were kind of "2001" in their theme and a bit more serious. After several google missions, and a swing through amazon's used and rare books, I've come up pretty much empty handed. Anyone else out there remember flipping through these books and planning your first trip to mars? Titles, authors, links or any hint what so ever would be appreciated!
