Armstrong gets piece of rock he took from moon

Even among astronauts, Neil Armstrong gets special respect — he was, after all, the first man to walk on the moon.

On Tuesday, the Apollo 11 astronaut got a piece of the moon rock he brought back to Earth.

"I get to keep it myself only so long as I speak today. So I'm going to be talking longer than usual," Armstrong, 75, joked at a ceremony in Cincinnati in which NASA presented him with the rock.

The rock — about 2 grams of medium light gray, fine-grained basalt encased in clear plastic — was part of NASA's Ambassadors of Exploration award. It was created to commemorate the 35th anniversary of the July 20, 1969, moon walk by Armstrong and fellow astronaut Buzz Aldrin.
