At NASA's Kennedy Space Center in Florida, workers check the "beanie cap" and the gaseous oxygen vent arm removed from Launch Pad 39B's fixed service structure before they are taken away on the transporter. A portion of the service structure is being removed for the pad's conversion as launch site for the Constellation Program's Ares I-X. The launch of the Ares I-X flight test is targeted for August 2009. Photo credit: NASA/Jim Grossmann
