In a matter of days, three Americans and one Canadian will set their sights on heading toward the moon for the first time in more than half-a-century.
Yes, robotic U.S. landers have begun to touch down on the moon in recent years. But ever since the Apollo era came to an end in 1972, humans have yet to venture back anywhere near Earth's celestial neighbor.
