On July 20, 1969, American astronaut Neil Armstrong was the first human being to set foot on our huge satellite, the Moon.  It was perhaps the most momentous achievement of Humanity, and to this day it has never been duplicated.  I think that every American should give a rousing cheer for America, and its space agency.  And never, ever forget that we were first.
