Do you recall what you were doing at 6:20 a.m. Wednesday morning October 3 last year? That’s a tough one but I feel fairly certain that I was just waking up to the sound of my wife’s hairdryer. At that same moment, the Mars Reconnaissance Orbiter spacecraft took this picture of Earth and moon from Mars orbit. Earth was 85 million miles away and oh-so-small in all that inky black. Yet you can make out some familiar features like clouds, parts of the North Atlantic and South Pacific oceans and even the west coast of South America (at lower right.)
Pictures like this one begin to give us some idea of the jewel that Earth truly is. They also allow us to see things in clearer perspective. Should I really be upset if the guy in front of me is going five miles under the speed limit? You know the answer to that one.
