Today, everyone is familiar with Neil Armstrong's famous words as he first set foot on the moon: "one small step for man; one giant leap for mankind." But America's journey to the moon was anything but simple. In 1957, the Soviet Union launched Sputnik, the world's first satellite, into orbit; later that year, America's first attempt was such a failure that the media nicknamed it "Kaputnik." Still, we didn't give up. With each failure, we gleaned valuable information about what went wrong, and how to avoid it in the future. So we tried again. And again. And each time we failed, we failed a little bit better.
