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 Atlas V, the space shuttle, the Delta II, the Titan IV, the Atlas II, the Apollo Saturn V, the Gemini Titan and the Mercury Redstone. In the foreground are human destinations the center helped NASA reach, including Earth's orbit and the International Space Station. At the top right is NASA's newest spacecraft, the Orion multi-purpose crew vehicle, which will help humans explore deeper into space than ever before. Image credit: NASA
