THEMIS: Dark slope streaks
THEMIS Image of the Day, August 29, 2014. Today’s VIS image shows dark slope streaks in an unnamed crater in Terra Sabaea. These features are believed to be formed by material moving downslope, removing the dust cover and revealing darker … Continue reading

HiRISE: Touring a dusty region
Dusty regions on Mars are often considered to look boring in HiRISE images because the dust obscures surface features. However, new meteor impacts are found most easily in dusty regions such as the one in this image because the new … Continue reading

More dust devilry in the air
Dust devils are the most dynamic feature on Mars, and scientists are zeroing in on how they work. An earlier Red Planet Report described dust devil motions as mapped by fortuitous simultaneous observations by cameras on two separate spacecraft. Now, … Continue reading
Airblast avalanches
The aerial blast wave from a meteorite impact can trigger dust avalanches in the vicinity, says a new paper published in Icarus. A group of scientists led by Kaylan Burleigh (University of Arizona) reached this conclusion after studying a cluster … Continue reading
