NASA is celebrating the 45th anniversary of the historic Apollo 11 mission to the moon. On July 20, 1969, Neil Armstrong and Buzz Aldrin, with crewmate Michael Collins manning the command service module from lunar orbit, became the first humans on the moon -- with Armstrong's historic first step onto the lunar surface becoming a symbolic giant leap for humanity. Today, with Apollo 11 as inspiration, NASA is taking the steps needed for America's next giant leap, to send astronauts to Mars. The path to Mars will use a stepping stone approach consisting of key elements, including human health and technology research aboard the International Space Station; development and evolution of NASA's Space Launch System rocket and Orion deep space capsule and development of other game-changing technologies to enable tomorrow's missions.
