   Explanation: [6]The weathered and layered face of Mount Mercou looms in
   the foreground of this mosaic from the Curiosity Mars rover's Mast
   Camera. Made up of 21 individual images the scene was recorded just
   after sunset on March 19, the 3,063rd martian day of Curiosity's on
   going exploration of the Red Planet. In the [7]martian twilight high
   altitude clouds still shine above, reflecting the light from the Sun
   below the local horizon like the [8]noctilucent clouds of planet Earth.
   Though water ice clouds drift through the thin martian atmosphere,
   [9]these wispy clouds are also at extreme altitudes and could be
   composed of frozen carbon dioxide, crystals of dry ice. Curiosity's
   Mast Cam has also imaged iridescent or [10]mother of pearl clouds
   adding subtle colors [11]to the martian sky.
