This beautiful high definition animation of the moon's rotation was captured by NASA's Lunar Reconnaissance Orbiter.
Declassified documents from the Cold War era show that the U.S. Air Force once had a plan to detonate a nuclear warhead on the surface of the Moon. According to CNN's interview with Leonard Reiffel, the leader of the little known top-secret plan Project A-119, the plan was hatched in 1958 shortly after the launch of the world's first satellite Sputnik 1, which brought pressure on the American government to catch up with the Soviet Union's lead in space exploration. Had the plan been set in motion, the bomb would've been launched from an undisclosed location to travel 240,000 miles to the moon and blow up on impact, though Reiffel believes its effect on the Moon would've been more or less negligible.
Neil Armstrong, the first man to walk on the moon, has died. He was 82.
Considered a hero to many the world over, Armstrong was granted honors from 17 countries, including the Presidential Medal of Freedom, and the Congressional Space Medal of Honor.
Born in Ohio in 1930, Armstrong served as a naval pilot at 19 -- the beginning of a long, impressive aerospace career that changed history as we know it. Upon his moon landing, he stated, "That's one small step for man, one giant leap for mankind."
A statement from Armstrong's family suggests his death was caused by complications of recent heart surgery. The family also left the world with this advice:
For those who may ask what they can do to honor Neil, we have a simple request. Honor his example of service, accomplishment and modesty, and the next time you walk outside on a clear night and see the moon smiling down at you, think of Neil Armstrong and give him a wink.
