Astronaut Mike Massimino of NASA's STS-125 crew was in town for the release of the IMAX Hubble 3D film and took some time to swing by Dalton and visit with the 4th grade (as well as the HS Astronomy Class and some 6th grade Science classes). He was only here for a short time and spoke about his recent trip to repair the Hubble Telescope.  His talk was accented by video and still photos from the mission and he was able to answer many questions afterward.  Before leaving, he presented Dalton with a plaque that contains a flag and patch that flew on the mission with his team.
