One hundred years ago, on December 14, 1911, Norwegian explorer Roald Amundsen and his party became the first people to reach the Earth's south pole. The name of the ship that carried Amundsen to Antarctica was the Fram. The image above shows a portion of Fram Rupes on the planet Mercury, a long scarp (cliff) formed by compressive forces generated as the planet's interior cooled and contracted.
