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

HiRISE: Landslides in Cerberus Fossae

Cerberus Fossae is a steep-sided set of troughs cutting volcanic plains to the east of Elysium Mons. Steep slopes on Mars have active landslides (also called “mass wasting”), and here we see evidence for two types of activity. First, the … 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

HiRISE: In the gullies and bedrock of Ius Chasma

This image was acquired in Ius Chasma, a major section of the western portion of the giant Valles Marineris trough. We see a portion of a steep slope with gullies extending downhill (towards bottom of image). Many of the gully … Continue reading

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

HiRISE: Eastern slope of Asimov Crater’s central pit

Asimov is an 84-kilometer diameter crater located in the southern ancient highlands of Mars. It is distinguished from other craters in this region in that it contains both a ring-depression just within the crater rim and a pit near the … Continue reading

HiRISE: Monitoring frost in Raga Crater

Monitoring frost in Raga Crater. We’re watching frost up-slope from known new gully flows in Raga. These appear to be distinct from recurring slope lineae we’ve seen in other craters. Beautiful Mars series. [More at links]

HiRISE: Monitoring frost in Corozal Crater

Monitoring frost in Corozal Crater. Corozal Crater has both active gullies and recurring slope lineae. We are monitoring the evolution of seasonal frost, which is the likely trigger for gully activity. Never mind the hulking shadow at the left. Beautiful … Continue reading

HiRISE: The Case of the Lurking Frost

HiRISE and the Case of the Lurking Frost. Sheltered by these cliffs, we can see frost build up, along with lots of sedimentary rocks. This area is also a good candidate for recurring slope lineae. Beautiful Mars series. [More at … Continue reading
