Dark sediments in the Medusae Fossae Formation. Beautiful Mars series.
Thin, blade-like walls, some as tall as a 16-story building, dominate a previously undocumented network of intersecting ridges on Mars, found in images from NASA’s Mars Reconnaissance Orbiter. The simplest explanation for these impressive ridges is that lava flowed into … Continue reading
The distinctively fluted surface and elongated hills in this image in Medusae Fossae are caused by wind erosion of a soft fine-grained rock. Called yardangs, these features are aligned with the prevailing wind direction. This wind direction would have dominated … Continue reading
Planetary Geomorphology Image of the Month, October 31, 2015: Lionel Wilson (Lancaster University, UK) and Peter Mouginis-Mark (University of Hawaii). Image 1 shows a distinctive flow deposit southwest of the Cerberus Fossae on Mars. The flow source is a ~20 … Continue reading
Sand filled crater in the Medusae Fossae region. Beautiful Mars series.
This beautifully contrasted infrared-color image shows an area approximately 600 by 900 meters. This is a close-up of the western Medusa Fossae formation where we can see dust-covered rocky, bedrock surfaces (beige) and a bluish-tinted sand sheet that transitions into … Continue reading
The dark dunes in the western Medusae Fossae formation provide some evidence of having a local origin. This image shows no large dunes, but many of the dark sand patches cover slopes up to discrete layers. It is possible that … Continue reading
Wind erosion of the Medusae Fossae Formation. Beautiful Mars series.
A linear ridge that winds for more than 200 kilometers (120 miles) through part of South Australia was a river channel roughly 10 million years ago. After the paleoriver stopped flowing, silica-rich groundwater seeped into the riverbed, cementing its sediments.
Explosive volcanic eruptions on an earlier Mars with a thicker atmosphere would have scattered fine ash (pyroclastic debris) mainly east or west of the volcano, a new study finds. Also, a denser ancient atmosphere supports the addition of Arsia and … Continue reading
