  • Title: HiRISE | Science in Motion
    Descriptive info: SCIENCE IN MOTION.. For a view of refereed articles using HiRISE data,.. click here.. Valles Marineris Dune Sediment Provenance and Pathways.. Matthew Chojnacki, Devon M.. Burr, Jeffrey E.. Moersch, James J.. Wray.. Dunes within the deep canyons of Valles Marineris appear to be locally and regionally derived from numerous sources, that include: wall outcrops, sedimentary-layered deposit, and landslides.. Image:.. ESP_034698_1655.. ABSTRACT.. Although low-albedo sand is a prevalent component of the martian surface, sources and pathways of the sands are uncertain.. As one of the principal present-day martian sediment sinks, the Valles Marineris (VM) rift system hosts a diversity of dune field populations associated with a variety of landforms that serve as potential sediment sources, including spur-and-gully walls, interior layered deposits (ILDs), and landslides.. Here, we test the hypothesis that VM dune fields are largely derived from a variety of local and regional (intra-rift) sediment sources.. Results show several dune fields are superposed on ancient wall massifs and ILDs that are topographically isolated from extra-rift sand sources.. Spectral analysis of dune sand reveals compositional heterogeneity at the basinal-, dune field-, and dune-scales, arguing for discrete, relatively unmixed sediment sources.. In Coprates and Melas chasmata, mapping is consistent with the principle sand source for dunes being Noachian-aged upper and lower wall materials composed of primary (igneous) minerals and glasses, some of which show evidence for alteration.. In contrast, dune fields in Capri, Juventae, and Ganges chasmata show evidence for partial sediment derivation from adjacent Early Hesperian-aged hydrated sulfate-bearing ILD units.. This finding indicates that these ILDs act as secondary sand sources.. Dunes containing soft secondary minerals (e.. g.. , monohydrated sulfate) are unlikely to have been derived from distant sources due to the physical weathering of sand grains during transport.. Isolated extra-rift dune fields, sand sheets, and sand patches are located on the plateaus surrounding VM and the adjoining areas, but do not form interconnected networks of sand pathways into the rift.. If past wind regimes (with respect to directionality and seasonality) were consistent with more recent regimes inferred from morphological analysis (i.. e.. , dune slip faces, wind streaks), and were sufficient in strength and duration, small dune populations within Aurorae Chaos and north of eastern VM might have resulted from extended sand pathways into VM.. However, we favor local and regional derivation of dune sand from a variety of intra-rift lithologic sources for most cases.. Dune sand sources and the mechanism by which the sand is liberated are discussed in the context of findings described herein, but are broadly applicable to analysis of sediment production elsewhere on Mars.. Article on Science Direct.. Recurring Slope Lineae in Equatorial Regions of Mars.. Alfred S.. McEwen, Colin M.. Dundas, Sarah S.. Mattson, Anthony D.. Toigo, Lujendra Ojha, James J.. Wray, Matthew Chojnacki, Shane Byrne, Scott L.. Murchie and Nicolas Thomas.. The presence of liquid water is a requirement of habitability on a planet.. Possible indicators of liquid surface water on Mars include intermittent flow-like features observed on sloping terrains.. These recurring slope lineae are narrow, dark markings on steep slopes that appear and incrementally lengthen during warm seasons on low-albedo surfaces.. The lineae fade in cooler seasons and recur over multiple Mars years.. Recurring slope lineae were initially reported to appear and lengthen at mid-latitudes in the late southern spring and summer and are more common on equator-facing slopes where and when the peak surface temperatures are higher.. Here we report extensive recurring slope linea activity in equatorial regions of Mars, particularly in the deep canyons of Valles Marineris, from analysis of data acquired by the Mars Reconnaissance Orbiter.. We observe the lineae to be most active in seasons when the slopes often face the sun.. Expected peak temperatures suggest that activity may not depend solely on temperature.. Although the origin of the recurring slope lineae remains an open question, our observations are consistent with intermittent flow of briny water.. Such an origin suggests surprisingly abundant liquid water in some near-surface equatorial regions of Mars.. Nature Geoscience.. Download the AGU presentation slide..

Heavily dissected hill in Juventae Chasm.. Sequence of 5 HiRISE images of a heavily-dissected (eroded) hill in southern Juventae Chasm, Mars (latitude 4.. 7 degrees S, longitude 298.. 6 degrees E).. This sequence is from the recently completed Mars Year (31), and RSL were also seen here in Mars Year 28, so they have recurred.. The season of these images is late spring to early summer in the southern hemisphere, and include perihelion (Mars closest to the sun in its orbit).. Activity is strongly concentrated on the south-facing slopes, which are the warmest slopes this time of year.. The RSL are closely associated with small (for Mars) gullies.. Images reduced to 1 m/pixel scale.. (31MB).. RSL and darkening fans in East Coprates Chasm.. Sequence of 6 images showing a small area of steep slopes with RSL activity (latitude 14.. 7 degrees S, longitude 304.. The sequence is in Mars Year 31, southern spring.. Note that some of the fans that RSL flow over became darker and brighter over time (.. see also figure S2 of the supplementary material of the Nature Geoscience paper).. There are many other such fans in this region that darkened and brightened at the same times.. Image 0.. 25 m/pixel scale; scene 480 meters wide.. (18MB).. RSL follow the sun in crater on Melas Chasm floor.. Sequence of 8 images showing RSL forming first on the north-facing slope (bottom), then switching to the south-facing slope (top).. This change occurred close to when the subsolar latitude moved from the north to the south of the latitude of this crater.. In other words, RSL are most active on the slopes that receive more direct sunlight.. There was also an episode of inactivity and fading of RSL on the south-facing slope, when the air over this region was especially dusty (Ls 235-246).. Dusty air makes the daytime temperatures cooler, which may have temporarily stopped the RSL activity.. (42MB).. RSL activity on complex topography in East Coprates Chasm.. The use of digital terrain maps (DTMs), constructed from HiRISE stereo images, helps characterize the RSL phenomena.. The images in other sequences have been DTM-projected to looking straight down on the surface, but here that have been projected to a view a person or rover on the surface could observe.. This sequence of 6 DTM-projected images shows RSL forming and fading on west-facing slopes in east Coprates Chasma (latitude 14.. North is to the left, and most slopes face south.. Flows appear to form from the upper-most 100 meters along this ridge, suggesting very concentrated sources, possibly from the light- and mid-toned bedrock.. Activity here is observed on all slope aspects and for the majority of the year, but RSL generally favor Sun-facing slopes.. (13MB).. RSL and colorful fans along Coprates ridge.. This site along Coprates ridge shows RSL on generally north-facing slopes in northern summer/southern winter (latitude 12.. 9 degrees S, longitude 295.. 5 degrees E).. South is down, and most slopes face northwest.. IRB color (near-infrared, red, and blue-green bandpasses displayed as red, green, and blue, respectively) with a min-max stretch illustrates the greenish fans and deposits associated with RSL.. Two of these fans transition downslope into ripples (.. see also figure 2 of the Nature Geoscience paper.. ).. All of the lineae here and in the larger scene appear to originate from relatively bright bedrock outcrops.. Note that some of the fans that RSL flow over became darker and brighter over time.. Image is approximately 950 meters wide.. Animated GIF captions by: Matt Chojnacki and Alfred McEwen.. Image credit: NASA/JPL/University of Arizona.. Prolonged magmatic activity on Mars inferred from the detection of felsic rocks.. James J.. Wray, Sarah T.. Hansen, Josef Dufek, Gregg A.. Swayze, Scott L.. Murchie, Frank P.. Seelos, John R.. Skok, Rossman P.. Irwin III & Mark S.. Ghiorso.. Rocks dominated by the silicate  ...   down slipfaces, and outbreaks of gas and sand around the dune margins.. These phenomena are concentrated on the north polar erg that encircles the northern residual polar cap.. The Mars Reconnaissance Orbiter has been in orbit for three Mars years, allowing us to observe three northern spring seasons.. Activity is consistent with and well described by the Kieffer model of basal sublimation of the seasonal layer of ice applied originally in the southern hemisphere.. Three typical weak spots have been identified on the dunes for escape of gas sublimed from the bottom of the seasonal ice layer: the crest of the dune, the interface of the dune with the interdune substrate, and through polygonal cracks in the ice.. Pressurized gas flows through these vents and carries out material entrained from the dune.. Furrows in the dunes channel gas to outbreak points and may be the northern equivalent of southern radially-organized channels ( araneiform terrain), albeit not permanent.. Properties of the seasonal CO2 ice layer are derived from timing of seasonal events such as when final sublimation occurs.. Modification of dune morphology shows that landscape evolution is occurring on Mars today, driven by seasonal activity associated with sublimation of the seasonal CO2 polar cap..

T.. Bridges, F.. Ayoub, J-P.. Avouac, S.. Leprince, A.. Lucas & S.. Mattson.. Strong and sustained winds on Mars have been considered rare, on the basis of surface meteorology measurements and global circulation models, raising the question of whether the abundant dunes and evidence for wind erosion seen on the planet are a current process.. Recent studies showed sand activity, but could not determine whether entire dunes were moving implying large sand fluxes or whether more localized and surficial changes had occurred.. Here we present measurements of the migration rate of sand ripples and dune lee fronts at the Nili Patera dune field.. We show that the dunes are near steady state, with their entire volumes composed of mobile sand.. The dunes have unexpectedly high sand fluxes, similar, for example, to those in Victoria Valley, Antarctica, implying that rates of landscape modification on Mars and Earth are similar..

McEwen, Lujendra Ojha, Colin M.. Mattson, Shane Byrne, James J.. Wray, Selby C.. Cull, Scott L.. Murchie, Nicolas Thomas, Virginia C.. Gulick.. Water likely flowed across ancient Mars, but whether it ever exists as a liquid on the surface today remains debatable.. Recurring slope lineae (RSL) are narrow (0.. 5-5 m), relatively dark markings on steep (25°-40°) slopes; repeat MRO/HiRISE images show them to appear and incrementally grow during warm seasons and fade in cold seasons.. They extend downslope from bedrock outcrops, often associated with small channels, and hundreds of them form in rare locations.. RSL appear and lengthen in the late southern spring/summer from 48°S to 32°S latitudes favoring equator-facing slopes--times and places with peak surface temperatures from ~250-300 K.. Liquid brines near the surface might explain this activity, but the exact mechanism and source of water are not understood.. Science: Is Mars Weeping Salty Tears?.. Read the University of Arizona press release.. View our breakout page for this paper.. Seasonal Erosion and Restoration of Mars Northern Polar Dunes.. Hansen, M.. Bourke, N.. T.. Bridges, S.. Byrne, C.. Colon, S.. Dundas, K.. Herkenhoff, A.. Mellon, G.. Portyankina, and N.. Despite radically different environmental conditions, terrestrial and Martian dunes bear a strong resemblance, indicating that the basic processes of saltation and grainfall (sand avalanching down the dune slipface) operate on both worlds.. Here we show that Martian dunes are subject to an additional modification process not found on the Earth: springtime sublimation of Mars CO2 seasonal polar caps.. Numerous dunes in Mars north polar region have experienced morphological changes within a Mars year, detected in images acquired by the High Resolution Imaging Science Experiment (HiRISE) on the Mars Reconnaissance Orbiter (MRO).. Dunes show new alcoves, gullies, and dune apron extension.. This is followed by remobilization of the fresh deposits by the wind, forming ripples and erasing gullies.. The widespread nature of these rapid changes, and the pristine appearance of most dunes in the area, implicates active sand transport in the vast polar erg in Mars current climate..

Mattson, C.. Verba, R.. A.. Beyer, P.. E.. Geissler, A.. McEwen, and the HiRISE Team.. We report on the discovery of columnar jointing in Marte Valles, Mars.. These columnar lavas were discovered in the wall of a pristine, 16-km-diameter impact crater and exhibit the features of terrestrial columnar basalts.. There are discontinuous outcrops along the entire crater wall, suggesting that the columnar rocks covered a surface area of at least 200 sq.. km, assuming that the rocks obliterated by the impact event were similarly jointed..
