View From a Height, by Joan D. Vinge

I think I have read View From a Height before, but this is a good audiobook version so it was nice to "read" it again. The one-way voyage is an inspired theme to build a SF story around, and this one is done well. The idea has been discussed for a mission to Mars as well. It's an interesting tour of ups and downs of deliberate, permanent isolation. I liked it, you will too.
