In this July 16, 1969 file photo provided by NASA, the Saturn V rocket that launched Neil Armstrong, Buzz Aldrin and Michael Collins on their Apollo 11 moon mission lifts off at Cape Kennedy, Fla. For the 45th anniversary of the Apollo 11 mission, Aldrin asked everyone to remember where they were when he and Armstrong became the first humans to step onto another heavenly body, and to share their memories online.
