THEMIS: Dark slope streaks
THEMIS Image of the Day, May 16, 2016. Today’s VIS image shows part of the rim of an unnamed crater in Terra Sabaea. Numerous dark streaks are visible. One theory of how the streaks form suggests that a rock or … Continue reading

HiRISE: Troughs in Elysium Fossae
The two linear depressions in this image form part of the Elysium Fossae complex, a group of troughs located in the Elysium quadrangle of Mars. These troughs are tectonic features, likely formed by the stretching, tearing and subsequent collapse of … Continue reading

THEMIS: Dark slope streaks
THEMIS Image of the Day, October 20, 2015. Dark streaks are visible on the slopes of hills and crater rims in Amazonis Planitia. It is thought that the removal of dust by downslope movement reveals the darker rocks beneath. More … Continue reading

HiRISE: Slope streak cluster formation
Slope streak cluster formation. These are not RSL, but dark streaks created by dislodged material, such as falling rocks or boulders. Beautiful Mars series.
