On Launch Complex-41 on Cape Canaveral Air Force Station in Florida, the Atlas V/Centaur rocket with NASA's Lunar Reconnaissance Orbiter, or LRO, and NASA's Lunar Crater Observation and Sensing Satellite, known as LCROSS, on top reach the launch pad. Circling the pad are the protective lightning towers. 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 .
