Obama, John Glenn Honor Armstrong

    FILE - This July 20, 1969 file photo provided by NASA shows Neil Armstrong. The family of Neil Armstrong, the first man to walk on the moon, says he died Saturday, Aug. 25, 2012, at age 82. A statement from the family says he died following complications resulting from cardiovascular procedures. It doesn't say where he died. Armstrong commanded the Apollo 11 spacecraft that landed on the moon July 20, 1969. He radioed back to Earth the historic news of "one giant leap for mankind." Armstrong and fellow astronaut Edwin "Buzz" Aldrin spent nearly three hours walking on the moon, collecting samples, conducting experiments and taking photographs. In all, 12 Americans walked on the moon from 1969 to 1972.  (AP Photo/NASA)

    The first man on the moon received tributes Sunday from the president and fellow space pioneers Buzz Aldrin, John Glenn, and Michael Collins. “Neil was among the greatest of American heroes—not just of his time, but of all time,” Obama said. “When he and his fellow crew members lifted off aboard Apollo 11 in 1969, they carried with them the aspirations of an entire nation.” Glenn echoed the president’s sentiments, saying, “When I think of Neil, I think of someone who for our country was dedicated enough to dare greatly.”
