Astronaut Scott Parazynski smiles for a photo while he and the crew of STS-120 walk around and look at the underside of the space shuttle Discovery shortly after their 1:01pm EST landing at NASA's Kennedy Space Center in Florida. Parazynski performed a repair of a damaged solar array during one of his spacewalks at the International Space Station. Photo Credit: "NASA/Bill Ingalls"
