1st Video of Moon's Far Side

chill writes "A gravity-mapping spacecraft orbiting the moon has beamed home its first video of the lunar far side — a view people on Earth never see. Because the moon is tidally locked with Earth, it only presents one face to the planet's surface (the near side). The side of the moon that faces away from Earth is the far side. Only robotic spacecraft and Apollo astronauts who orbited the moon in the 1960s and 1970s have seen the far side of the moon directly."
