I picked up from wickedthought that NASA is celebrating its 50th anniversary. He points to this article that celebrates the occasion by outlining 50 ways that NASA's work has changed life on Earth. I'm pointing this out mainly just because it reminds me of a discussion Jay-Jay and I had one night about whether or not space exploration was worth it. I just found it interesting to see what kind of side-effects the work has had on Earth. And it's cool that while so many of these effects are technology-centered, most of them came as a result of research; so few of them resulted from actually going into space.
And, yes, that article is in The Independent from the UK. No, I don't really get it, either.
