JSC2006-E-18117 (May 2006) --- Computer-generated artist’s rendering of the Space Shuttle Discovery docked to the International Space Station. This close-up angle shows the position of the shuttle robotic system that allows astronauts to get on the end of the boom for a test of the 50-foot robotic arm boom extension, usually used for remote shuttle Thermal Protection System (TPS) inspections, as a potential work platform for hard-to-reach repair sites on the bottom of the orbiter for Detailed Test Objective (DTO) 849. The test is to be conducted during the first spacewalk of STS-121.
