This weekend marks the 45 year anniversary of the Apollo 11 mission landing the first men on the Moon.

The very first time a member of the human race stepped onto another planet besides the one on which it was born.

The only sentient life form on Earth that has developed the technological ability to leave its planetary home, visit another, and return safely.

The only other heavenly body besides the Earth that has had members of the human race standing upon it.  Perhaps—who knows?—the only heavenly body that has been visited by a sentient life form from another heavenly body.

Just take a moment to dwell on that.  Happy weekend.
