Winds have removed and deposited fine material around the craters. The winds were blowing from right to left - east to west. 2009-11-09 ]]> http://themis.asu.edu/zoom-20091106a This unnamed channel is draining the area of between Coracis Fossae and Bosporos Planum. 2009-11-06 ]]> http://themis.asu.edu/zoom-20091105a This VIS image shows a small section of Reull Vallis. 2009-11-05 ]]> http://themis.asu.edu/zoom-20091104a This VIS image shows a complex section of Nirgal Vallis. 2009-11-04 ]]> http://themis.asu.edu/zoom-20091102a This VIS image, collected simultaneously with yesterday's IR image, shows the western margin of the dune field in Rabe Crater. Note the change in topography from the bottom to the top of the frame (the top is the lowest part of the depression). 2009-11-02 ]]> http://themis.asu.edu/zoom-20091030a This daytime infrared image shows part of the dune field on the floor of Rabe Crater. 2009-10-30 ]]> http://themis.asu.edu/zoom-20091029a This VIS image shows the same dune field as yesterday's IR image. Note that the dunes in Kaiser Crater do not completely cover the crater floor between the dunes. 2009-10-29 ]]> http://themis.asu.edu/zoom-20091028a This daytime IR image shows part of the dune field located on the floor of Kaiser Crater. 2009-10-28 ]]> http://themis.asu.edu/zoom-20091027a Today's VIS image was collected simultaneously with yesterday's IR image. The VIS image shows individual dunes that are part of the large Aonia Terra dune field. 2009-10-27 ]]> http://themis.asu.edu/zoom-20091026a Continuing our survey of non-crater dune fields brings us to this group of dunes in Aonia Terra. The daytime IR illustrates the warmth of the dune material compared to the surrounding materials. 2009-10-26 ]]> http://themis.asu.edu/zoom-20091023a Today's VIS image provides a closer look at yesterday's dune field. 2009-10-23 ]]> http://themis.asu.edu/zoom-20091022a Not all dune fields on Mars are located on the floors of impact craters. This extensive dune field is located on the plains of Terra Cimmeria. 2009-10-22 ]]> http://themis.asu.edu/zoom-20091021a Collected simultaneously with yesterday's infrared image, this VIS image of the dunes within Rabe Crater illustrates the change in topography in the dune field. 2009-10-21 ]]> http://themis.asu.edu/zoom-20091020a This daytime infrared image of Rabe Crater shows the large dune field located within the crater. Note that the dunes are not confined to the lowest elevation depressions on the crater floor. 2009-10-20 ]]> http://themis.asu.edu/zoom-20091019a This VIS image, acquired simultaneously with yesterday's IR image, highlights the complexity and variety of dune forms on the floor of Russell Crater. 2009-10-19 ]]> http://themis.asu.edu/zoom-20091016a This daytime infrared image shows the complex dune field located on the floor of Russell Crater. The bright tone indicates the warmth of the dunes compared to the surrounding materials. 2009-10-16 ]]> http://themis.asu.edu/zoom-20091015a Taken at the same time as yesterday's infrared image, this VIS image shows the dune forms on the floor of Proctor Crater. 2009-10-15 ]]> http://themis.asu.edu/zoom-20091014a This daytime IR image shows the sand sheet with dune forms located on the floor of Proctor Crater. 2009-10-14 ]]> http://themis.asu.edu/zoom-20091013a This daytime IR image shows more of the plains and crater dune fields of Terra Cimmeria. 2009-10-13 ]]> http://themis.asu.edu/zoom-20091012a This daytime IR image shows several dune fields in the plains of Terra Cimmeria. Note the dune field in the samll crater towards the bottom of the frame. The dune field has climbed the western rim of the crater and is moving out onto the plains. 2009-10-12 ]]> http://themis.asu.edu/zoom-20091009a This daytime IR image shows a large sandsheet with dune forms in Terra Cimmeria. 2009-10-09 ]]>
