HiRISE: Gullies and craters and dunes, oh my!
This unnamed, approximately 30-kilometer diameter crater, formed in the Southern highlands of Mars. Our image shows regions of geologic diversity within, making this an interesting spot for scientists to study how different Martian processes interact with each other. Gullies, or … Continue reading

HiRISE: Active flows on steep slopes in Ganges Chasma
This image covers a steep west-facing slope in southwestern Ganges Chasma, north of the larger canyons of Valles Marineris. The spot was targeted both for the bedrock exposures and to look for active slope processes. We see two distinct flow … Continue reading

HiRISE: Seasonal flows in Valles Marineris
Recurring slope lineae (RSL) are seasonal flows on warm slopes, and are especially common in central and eastern Valles Marineris. This image covers a large area full of interesting features, but the enhanced color closeup highlight some of the RSL. … Continue reading

HiRISE: Colorful equatorial gullies in Krupac Crater
Although large gullies (ravines) are concentrated at higher latitudes, there are gullies on steep slopes in equatorial regions. An enhanced-color closeup shows part of the rim and inner slope of Krupac Crater located just 7.8 degrees south of the equator. … Continue reading

HiRISE: Seasonal flows on warm slopes
Recurring Slope Lineae (called “RSL”) are seasonally-repeating dark flows that are active at the warmest times of the year. Some of these grow from the top of the steep slope downwards as expected for liquid or granular flows. Others show … Continue reading

HiRISE: Slope streaks or recurring slope lineae?
The image shows a region we see many slope streaks, typically dark features on slopes in the equatorial regions on Mars. They may extend for tens of meters in length and gradually fade away with time as new ones form. … Continue reading

THEMIS: Gullies, ejecta at Palikir Crater
THEMIS Image of the Day, October 27, 2016. Today’s VIS image is of Palikir Crater in Terra Sirenum. The inner rim of the crater is dissected with numerous gullies. In higher resolution images from other imagers these gullies are the … Continue reading

No damp ground found at RSL seasonal streaks
Seasonal dark streaks on Mars that have become one of the hottest topics in interplanetary research don’t hold much water, according to the latest findings from a NASA spacecraft orbiting Mars. The new results from NASA’s Mars Odyssey mission rely … Continue reading

Do salts draw water from atmosphere for RSLs?
Puzzles persist about possible water at seasonally dark streaks on Martian slopes, according to a new study of thousands of such features in the Red Planet’s largest canyon system. The study published today [in the Journal of Gephysical Research] investigated … Continue reading

Curiosity may hunt for RSLs on Mt. Sharp
Ever since it was announced that there may be evidence of liquid water on present-day Mars, NASA scientists have wondered how best to further investigate these long, seasonally changing dark streaks in the hope of finding evidence of life — … Continue reading
