A wide view captures both Launch Complex-41 on Cape Canaveral Air Force Station at right and Launch Pad 39A at NASA's Kennedy Space Center in Florida at left. Space shuttle Endeavour is still on the pad after launch was officially scrubbed at 1:55 a.m. this morning when a gaseous hydrogen leak occurred at the Ground Umbilical Carrier Plate. NASA's Lunar Reconnaissance Orbiter, or LRO, and NASA's Lunar Crater Observation and Sensing Satellite, known as LCROSS, are on Complex 41 waiting for launch on the Atlas V/Centaur rocket. LRO and LCROSS are the first missions in NASA's plan to return humans to the moon and begin establishing a lunar outpost by 2020. The LRO also includes seven instruments that will help NASA characterize the moon's surface: DIVINER, LAMP, LEND, LOLA, CRATER, Mini-RF and LROC. Launch is scheduled for 5:22 p.m. EDT June 18 .
