I was born the same week NASA was founded, so we're the same age and feel some of the same pains, joys, and frustrations.

Three and a half million years ago our ancestors - yours and mine - left these traces [indicates footprints]. We stood up and parted ways from them. Once we were standing on two feet, our eyes were no longer fixated on the ground. Now, we were free to look up and wonder.

Merry Christmas to all. A Pagan holiday (BC) becomes a Religious holiday (AD). Which then becomes a Shopping holiday (USA).

NASA was invented as a response to Cold War steps. There are those who presumed that we went to the moon because we're explorers. We went to the moon because we were at war with the Soviet Union. And so when it became clear that they (Soviet Union) were not going to the moon, we're done with the moon.

Mars once was wet and fertile. It's now bone dry. Something bad happened on Mars. I want to know what happened on Mars so that we may prevent it from happening here on Earth.

Last I checked, Bill Gates was worth $50 billion. If the average employed adult, who is walking in a hurry, will pick up a quarter from the sidewalk, but not a dime, then the corresponding amount of money given their relative wealth that Bill Gates would ignore if he saw it lying on the street is $25,000.

There are countless space activities that would be no less exciting than the moon missions were, I have no doubt. The search for life on Mars, for example.
