I just heard a story on NPR about the space suit that Neil Armstrong wore on the moon. Never intended to last more than 6 months, the suit has lasted 50 years, although it has deteriorated. After some restoration, it is now back on the exhibit at the National Air and Space Museum. I want to visit it there, and see it for myself, in person. It represents a pinnacle of human achievement, one we may never attain again, or perhaps we may surpass.
