THEMIS: Sirenum Fossae
THEMIS Image of the Day, July 3, 2015. The linear features in this VIS image are faults. Where depressions are formed bounded by faulting the feature is called a graben. These faults and graben are part of a large region … Continue reading

HiRISE: Gigas Sulci
A sulcus (or sulci, plural) is defined as “subparallel furrows and ridges.” This is a purely descriptive term for landforms that could have a variety of origins. At this location it appears to be a graben (which is a fault-bounded … Continue reading

THEMIS: Sirenum Fossae
THEMIS Image of the Day, May 28, 2015. The THEMIS VIS camera contains 5 filters. The data from different filters can be combined in multiple ways to create a false color image. These false color images may reveal subtle variations … Continue reading

THEMIS: More Sirenum Fossae
THEMIS Image of the Day, May 1, 2015. The subtle paired fractues at the bottom of this VIS image are part of Sirenum Fossae, though it is hundreds of km away from yesterday’s image location. Numerous gullies at the top … Continue reading

HiRISE: Gullies & layers near Mariner Crater
Gullies are commonly found in the southern mid-latitudes of Mars. In this image they start near top of a long ridge, and descend into an impact crater that lies at the bottom of the ridge, moving through a rocky layer … Continue reading
