MARS RECONNAISSANCE ORBITER HIRISE IMAGES
September 16, 2015
o Western Medusa Fossae Formation: Dust and Dunes
The bluish sand in this image is thought to originate
from the bedrock that lies beneath the dust.
o Possible Sulfates in the Northeast Syrtis Major Region
This particular region has been studied intensely due to the
presence of volcanics from Syrtis Major and impact ejecta
from the Isidis Basin.
o Which Came First?
Let's untangle the history of certain formations in this image
of sand dunes trapped inside an unnamed crater in southern
o Bizarre TARs
Unlike other transverse aeolian ridges on Mars, these TARs have
blunt edges and serrated ridges. Why?
All of the HiRISE images are archived here:
