This MOC image shows some dark slope streaks in the Phlegra Dorsa region of Mars. Of particular interest is the split streak near the center of the image, which diverted around a rounded hill as the material was sliding down the slope

The channel feature in this image from NASA 2001 Mars Odyssey spacecraft is called Mangala Fossa. This feature was formed by tectonic activity, with the walls being faults that allowed the central portion to slide downward forming a graben.

Most of the hills in this image from NASA 2001 Mars Odyssey spacecraft have dark streaks thought to be where bright dust has been removed by sliding down the hillside.

Echus Chaos is a region of low hills located between Lunae Planum (to the right of this image) and Echus Palus (to the left of this image). This chaos terrain may have formed as the rocks that make up Lunae Planum slowly slid downhill into Echus Palus. As these rocks slid downhill, they broke up into large pieces that formed the hills that we see today. What caused this landslide is not well known, but it could have been due to large floods of water moving through Echus Palus, causing the edge of Lunae Planum to become soaked and fall apart. Ground shaking from movement along nearby faults or meteorite impacts may have also helped to make the edge of Lunae Planum unstable and collapse. https://photojournal.jpl.nasa.gov/catalog/PIA25556

This composite NASA Hubble Space Telescope Image captures the positions of comet Siding Spring and Mars in a never-before-seen close passage of a comet by the Red Planet, which happened at 2:28 p.m. EDT October 19, 2014. The comet passed by Mars at approximately 87,000 miles (about one-third of the distance between Earth and the Moon). At that time, the comet and Mars were approximately 149 million miles from Earth. The comet image shown here is a composite of Hubble exposures taken between Oct. 18, 8:06 a.m. EDT to Oct. 19, 11:17 p.m. EDT. Hubble took a separate photograph of Mars at 10:37 p.m. EDT on Oct. 18. The Mars and comet images have been added together to create a single picture to illustrate the angular separation, or distance, between the comet and Mars at closest approach. The separation is approximately 1.5 arc minutes, or one-twentieth of the angular diameter of the full Moon. The background starfield in this composite image is synthesized from ground-based telescope data provided by the Palomar Digital Sky Survey, which has been reprocessed to approximate Hubble’s resolution. The solid icy comet nucleus is too small to be resolved in the Hubble picture. The comet’s bright coma, a diffuse cloud of dust enshrouding the nucleus, and a dusty tail, are clearly visible. This is a composite image because a single exposure of the stellar background, comet Siding Spring, and Mars would be problematic. Mars is actually 10,000 times brighter than the comet, and so could not be properly exposed to show detail in the Red Planet. The comet and Mars were also moving with respect to each other and so could not be imaged simultaneously in one exposure without one of the objects being motion blurred. Hubble had to be programmed to track on the comet and Mars separately in two different observations. The images were taken with Hubble’s Wide Field Camera 3.

The terrain in this observation from NASA Mars Reconnaissance Orbiter looks like an ancient uplifted crustal block. The area is riddled with faults big cracks that allow rocks to slide and ridges that look like uncovered magma dikes. A Mars Orbital Camera picture shows the region to be moderately dusty, but rocks do poke out along the ridges. With a high resolution images, we want to know if the dikes are of the same composition as the flood lavas that surround this high terrain. And what material did the dikes intrude upon which can be eroded away? http://photojournal.jpl.nasa.gov/catalog/PIA19287

A technician slides an imaging spectrometer instrument, which will measure the greenhouse gases methane and carbon dioxide from space, into a thermal vacuum test chamber at NASA's Jet Propulsion Laboratory in Southern California in July 2023. The thermal vacuum chamber test is one of a series meant to ensure that the instrument can withstand the rigors of launch and the harsh conditions of space. Engineers use the chamber to subject the spectrometer to the extreme temperatures it will encounter in the vacuum of space. The instrument shipped Sept. 12, 2023, from JPL to Planet Labs PBC in San Francisco, where it will be integrated into a Tanager satellite. Designed and built by JPL, imaging spectrometer will be part of an effort led by the nonprofit Carbon Mapper organization to collect data on greenhouse gas point-source emissions. The information will help locate and quantify "super-emitters" – the small percentage of individual sources responsible for a significant fraction of methane and carbon dioxide emissions around the world.

There the module will be prepared for delivery to the International Space Station on a future space shuttle mission. Columbus will expand the research facilities of the station and provide researchers with the ability to conduct numerous experiments in the area of life, physical and materials sciences.

Gullies are often found on steep slopes. In the winter, this area is covered with a layer of carbon dioxide ice (dry ice). In the spring, when the ice warms up and transitions to gas, it dislodges material on the slope, forming a gully. In general, this process works best on fine material, leaving behind large boulders. These boulders can be seen collected in the gully alcoves. Occasionally, boulders slide or roll downhill, like those sprinkled downslope in this image. This set of gullies is found at -71 degrees latitude in the Southern hemisphere. http://photojournal.jpl.nasa.gov/catalog/PIA19295

Dust and sand slide down slopes on Mars in little avalanches. Dark slope streaks are thought to be the result of the relatively bright colored dust avalanching down slopes, revealing the darker, coarser sand underneath. This image is the latest in a sequence of images of this crater that started in 2013. The goal is to watch the dusty slopes, and try to understand more about the processes that drive these little avalanches. https://photojournal.jpl.nasa.gov/catalog/PIA23757

iss064e005561 (November 24, 2020) --- Flight Engineer Kate Rubins pauses for a photo during operations (OPS) to install MISSE (Materials International Space Station Experiment) Transfer Tray 2 (MTT 2) on the JEM (Japanese Experiment Module) Orbital Replacement Unit Transfer Interface (JOTI) attached to the JEM Airlock (JEMAL) Slide Table. Photo was taken in the Kibo JEM.

The linear features in this VIS image is part of Labeatis Fossae. Fossae are linear depressions, most often caused by extensional tectonic forces pulling the crust apart and allowing material to slide downward between bounding faults. This type of feature is called a graben. Orbit Number: 85530 Latitude: 29.693 Longitude: 286.169 Instrument: VIS Captured: 2021-03-26 20:32 https://photojournal.jpl.nasa.gov/catalog/PIA24851

NM18-302-038 (28 June 1995) --- Astronaut Norman E. Thagard, Mir-18 cosmonaut researcher, took this picture aboard Mir on the eve of the targeted arrival day of Atlantis. Thagard told a July 18 press conference audience in Houston that he worked to clean the area prior to the Mir-19 crew and the STS-71 crew arrival and that his showing of this slide represented the first time the crew would have seen the area "in this condition."
