It jsut looks like the space exploration people saying "look - we're not entirely a useless waste of money", whereas I tend to think they are, of course. Yes, even taking into account the Teflon and the contact lenses.

I can't argue it's a money maker, but there are many more benefits we've gained from the space programs than you're implying, we just don't usually know they came out of that. To give just one more tangible item, i benefit from it every day in my profession... knitting! Yarns, fabrics, and sports clothing have been hugely revolutionized by the science of artificial fibers advanced by the space program, and i'm not being facetious. Artificial fibers didn't used to be able to wick moisture away from the body (let alone do it at different rates needed by various sports), keep a person warm (and still be light), or be soft or versitile. At this moment, in fact, i'm wearing a scarf that feels as soft as rabbit fur, but it's 100% Polyamide (it's called, "Baby Monkey"

And don't forget Tang. What would DO without Tang?!?!?!?!?! ROF.
