Spacewalker Drew Feustel gets his bearings for his first spacewalk after exiting the airlock in Atlantis's payload bay in this image from NASA TV May 14, 2009. Feustel and John Grunsfeld (not pictured) will replace a camera that allows large-scale, clear and detailed photos to be taken and a computer system that formats science data for researchers on the ground. The component replacements will keep the telescope functioning into at least 2014. [Agencies]
