Do slope streaks show global-scale water processes on Mars today?
[Editor’s note: From a paper by Anshuman Bhardwaj and three co-authors recently published in Reviews of Geophysics.] Are Slope Streaks Indicative of Global‐Scale Aqueous Processes on Contemporary Mars? • We provide a systematic survey and evaluation of the literature covering … Continue reading

How does boiling water reshape Mars terrain?
At present, liquid water on Mars only exists in small quantities as a boiling liquid, and only during the warmest time of day in summer. Its role has therefore been considered insignificant until now. However, an international team including scientists … 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.

HiRISE: Bright slope streaks in Arabia Terra
This observation shows bright and dark slope streaks in craters in the Arabia Terra region. Slope streak formation is among the few known processes currently active on Mars. The cause of slope streaks is still debated, and both dry and … Continue reading

Slope streaks not becoming more common; survive for decades
Slope streaks are dark lines that run down dusty slopes on Mars; scientists explain them as dust avalanches touched off by rockfalls or some similar trigger. (Slope streaks differ in nature and cause from a different kind of streak, dubbed … 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
