On this day (December 16) back in 1992 the Galileo spacecraft looked back at Earth from a distance of about 3.9 million miles (6.2 million kilometers). Though the Moon appears to be behind the Earth it is actually in the foreground and its orbital plane take it from left to right. With that thought in mind, realize that you are actually seeing much of the far side of the Moon which stays out of our view here on Earth. That’s right; the Moon has no permanent “Dark Side” as all parts of the Moon receive equal light. Relative to the Earth’s surface it does however, have a “Far Side”.
Galileo made two Earth fly-by’s en route to its destination, Jupiter where it died on September 21, 2003 by plunging into Jupiter and never returning.
