o Impacts from MSL Tungsten Blocks and Cruise Stage

  MSL (Curiosity) in cruise configuration jettisoned two 75-kilogram
  tungsten blocks just before atmospheric entry, used as cruise balance

o Columnar Jointing on Mars and Earth

  Finding evidence for large amounts of liquid water on Mars is important
  for understanding the planet's climate history and habitability.

o Colorful Fractured Bedrock in Ritchey Crater

  The dark, ridgelike lines that cut across the colorful blocks may be dikes,
  formed when molten rock forced its way into pre-existing linear fractures
  in the surrounding rock.

o Apostrophe Dunes

  The lack of symmetry within these dunes tells us that there is more than one
  wind direction acting here.
