On launch Pad 39B at NASA's Kennedy Space Center in Florida, a platform is being lifted onto the fixed service structure to be installed where the oxygen vent arm and hood were removed. The pad was transferred from the Space Shuttle Program to the Constellation Program. The ground operations team is modifying pad B for the Ares I-X rocket launch. Modifications also include installing access platforms and a vehicle stabilization system. The Ares I-X flight test is targeted for no earlier than Aug. 30. Photo credit: NASA/Jack Pfaller
