MARS RECONNAISSANCE ORBITER HIRISE IMAGES
December 21, 2016

o Lace on Mars
  http://www.uahirise.org/ESP_046414_0990

  Channels formed by sublimation of a layer of seasonal dry ice are so
  dense in this area that they look like lace.

o Spiders on Mounds
  http://www.uahirise.org/ESP_046562_1005

  This landform is uniquely Martian, formed in the spring as seasonal
  dry ice turns directly into gas.

o Secondary Craters
  http://www.uahirise.org/ESP_046876_1465

  Secondary impact craters are both interesting and vexing, but can be
  used to constrain the age of the surface where they fell.

o Soffen Crater Floor
  http://www.uahirise.org/ESP_047561_1560

  This crater on Mars was named after Dr. Gerald A. Soffen, project
  scientist for NASA's Viking program for Mars landers.
