After bagging the MESSENGER (Mercury Surface, Space Environment, Geochemistry and Ranging) spacecraft, Boeing workers at Astrotech Space Operations in Titusville, Fla., place the first part of a transportation canister around the Delta II upper stage booster. MESSENGER will be transferred to Launch Pad 17-B at Cape Canaveral Air Force Station, Fla. Liftoff of MESSENGER aboard a Boeing Delta II Heavy rocket is scheduled for Aug. 2. The spacecraft is expected to reach orbit around the planet in March 2011. MESSENGER was built for NASA by the Johns Hopkins University Applied Physics Laboratory in Laurel, Md.
