HiRISE: Stairway to Danielson
Stairway to Danielson. Previous images showed possible recurring slope lineae here in Danielson Crater. Additional images are needed to confirm their existence, but it’s the stair-stepped layers that also capture our attention for their stark beauty. HiRISE Picture of the … Continue reading

HiRISE: Southeast Hale Crater ejecta
Southeast Hale Crater ejecta. This image can help us determine whether there are one or multiple ejecta lobes in this region. Hale Crater is often imaged by HiRISE for the presence of recurring slope lineae, or flows that may or … Continue reading

HiRISE: Slope monitoring on Ganges Mensa
Slope monitoring on Ganges Mensa. An existing stereo pair shows dark lineations that look very much like recurring slope lineae, but did not exhibit any observed growth within a 1-month interval of the stereo pair, unlike RSL. This picture is … Continue reading

HiRISE: In etched terrain
In etched terrain. A previous image here showed evidence of recurring slope lineae, so this picture is a follow-up to see if this might be a good candidate for them, although the lineae really aren’t very prominent. Still, we have … Continue reading

Recurring slope lineae: Brines more likely
[Editor’s note: From a paper by Christian Huber and three co-authors recently published in Icarus.] Physical models and predictions for Recurring Slope Lineae formed by wet and dry processes • We test dynamic models of wet and dry RSL propagation … Continue reading
HiRISE: The hills in Eos Chasma
The hills in Eos Chasma. They may not be alive with the sound of music, but we’ll take the opportunity to look for recurring slope lineae, small gullies and slumped material. HiRISE Picture of the Day archive. [More at links]

HiRISE: Slope monitoring
Slope monitoring. The recurring slope lineae (RSL) in this image are large and have high contrast. Most importantly, we see multiple examples of RSL flowing on bedrock, alternating between bedrock and regolith and bedrock and regolith, and regolith only. Do … Continue reading

HiRISE: Majestic slopes and ridges
Majestic slopes and ridges. The objective of this observation is to take a closer look at recurring slope lineae-like features and confirm if they are actually present. Additionally, we previously had no HiRISE coverage of this particular spot. The sheer … Continue reading

Groundwater origin for recurring slope lineae?
In mid-2018, researchers supported by the Italian Space Agency detected the presence of a deep-water lake on Mars under its south polar ice caps. [Ed. note: previously reported here.] Now researchers at the USC Arid Climate and Water Research Center … Continue reading
