The spacecraft Galileo, and its demise this past Sunday, is the subject of what I consider to be Steven Den Beste's best post ever. Read it. It's not just about Galileo, but also about why NASA has had mission failures. But it's not gloom-and-doom, and I have to like any post about space exploration and space science that ends with the sentence "The best is yet to come."
Yeah, Steven, I know you said a few days ago that putting together a book of your thoughts, of any sort, would be too much like work. But if you did put out a book of your science and engineering stuff, I'd read it. (Just leave out that post about Attack of the Clones, though. Not your finest hour. Heh.)
