Space Shuttle Discovery lifted off Tuesday, July 26 from NASA's Kennedy Space Center, Fla. at 10:39 a.m. EDT, returning the Shuttle fleet to space and beginning a journey of exploration to the Moon, Mars and beyond.

During their 12-day mission to the International Space Station, the STS-114 crew will test new techniques and equipment designed to make Shuttles safer. They'll also deliver supplies and make repairs to the Space Station after Discovery docks on Thursday July 28.
