      Explanation: Tidally locked in synchronous rotation, the Moon always   
      presents its familiar nearside to denizens of planet Earth. From lunar   
      orbit, the Moon's farside can become familiar, though. In fact this   
      sharp picture, a mosaic from the Lunar Reconnaissance Orbiter's wide   
      angle camera, is centered on the lunar farside. Part of a global mosaic   
      of over 15,000 images acquired between November 2009 and February 2011,   
      the highest resolution version shows features at a scale of 100 meters   
      per pixel. Surprisingly, the rough and battered surface of the farside   
      looks very different from the nearside covered with smooth dark lunar   
      maria. A likely explanation is that the farside crust is thicker,   
      making it harder for molten material from the interior to flow to the   
      surface and form dark, smooth maria.
