ESA's Mars Express orbiter imaged the snow-laden region of Rupes Tenuis on the martian north pole on July 29, 2008. The images are centered around 81° north and 297° east and have a ground resolution of 41 m/pixel. They cover an area of about 44 000 km2, almost as large as the Netherlands.  Rupes Tenuis is located at the southern edge of the martian north polar cap, approximately 5500 km northeast of the Tharsis volcanic region. At present, polar caps contain the largest water...

  • Figuratively, a peevish, testy, ill-natured person.
