Hubble servicing mission on NASA’s mind

With the successful mission of Atlantis under its belt, NASA is looking toward a Hubble servicing mission. This makes me happy. I have decidedly mixed feelings about these last few Shuttle missions, but if Hubble gets upgraded -- and there are two advanced and very cool cameras that have been sitting in a warehouse for years now waiting to be taken up -- then that means the waning years of the Shuttle were good for something.
