CAPE CANAVERAL, Fla. -- Throughout the past 50 years, NASA's Kennedy Space Center has carried on America's legacy of processing, testing and launching a wide array of rockets and spacecraft to distant planets and other destinations in space. Launch vehicles, from left, include the Mercury Atlas, Gemini Titan, Apollo Saturn V, Atlas, Delta and the space shuttle.
