Space Walking

In current news, Astronaut Michael Massimino walked into space to repair a portion of the Hubble Telescope. At one point he had to remove 111 tiny screws in order to access the area of the Hubble needing parts replaced. He had to count each one as it was placed into a disposal bag, being careful not to drop one or else it could become a tiny missile. Traveling at 17,600 mph, the smallest of object could end it all. In one hour the Hubble travels more than most Americans travel in a year in their automobiles.
Cool images here.
The Hubble is already 19 years old, but these repairs could keep it going for another 5-10 years. We are lucky to see results from its discoveries in our lifetime.
Dork, out.
