CAPE CANAVERAL, Fla. – United Launch Alliance's Delta II rocket, with NASA's Kepler spacecraft aboard, is bathed in light on Launch Pad 17-B at Cape Canaveral Air Force Station in Florida prior to launch. Liftoff is planned for 10:49 p.m. EST. Kepler is a spaceborne telescope designed to search the nearby region of our galaxy for Earth-size planets orbiting in the habitable zone of stars like our sun. The habitable zone is the region around a star where temperatures permit water to be liquid on a planet's surface. The challenge for Kepler is to look at a large number of stars in order to statistically estimate the total number of Earth-size planets orbiting sun-like stars in the habitable zone. Kepler will survey more than 100,000 stars in our galaxy. Photo credit: NASA/Jack Pfaller
