The seven members of the STS-125 astronaut crew, who repaired and upgraded NASA's Hubble Space Telescope in May 2009, celebrated the success of Servicing Mission 4 with staff, family members, and friends at the Space Telescope Science Institute on July 21.

Here, they posed in front of the winning entries in the Classroom Collage Activity contest, which were on display at STScI. The Odyssey School's "pinwheel-collage" can be seen behind the astronauts, at far right, and Thurgood Marshall Elementary School's Hubble "model-collage" is in the background, at center.
