202 Chapter 5 FUTURE WORK There is more work is planned for these projects. Some of the proposed future work fell out of the questions and problems that arise while first attempting to solve a problem. Some of it was originally intended to be encompassed in the thesis work, but work at an earlier stage grew to dominate the project as a result of the sheer volume of data available. Many questions were left unanswered in the work described in Chapter 4. It is not clear why the MM5 does not predict the secondary winds that clearly must exist in the current wind regime. These winds do not appear in GFDL GCM model runs, and they may not exist in any current atmospheric model. It is possible that they are produced by rare storms (i.e., storms that occur once a decade or century), and I would like to look into the possibility of observing or predicting these storms. The MM5 also does not predict winds strong enough to lift basaltic grains into saltation. This may simply be a problem of model resolution, and it is not a difficult prospect to run the model at a higher resolution and/or to output the strongest hourly winds at each grid point rather than the winds at the top of each hour. There is also the problem that the MM5 is meant to hold subgrids that are no more than three times smaller than their parent grids – and yet our model runs at a scale of 10 km were more than an order of magnitude higher resolution than the parent grid. -

Edgett – 27 September 2010 Simulated view from Curiosity rover in landing ellipse looking toward the field area in Gale; made using MRO CTX stereopair images; no vertical exaggeration. The mound is ~15 km away 4th MSL Landing Site Workshop, 27–29 September 2010 in this view. Note that one would see Gale’s SW wall in the distant background if this were Edgett, 1 actually taken by the Mastcams on Mars. Gale Presents Perhaps the Thickest and Most Diverse Exposed Stratigraphic Section on Mars • Gale’s Mound appears to present the thickest and most diverse exposed stratigraphic section on Mars that we can hope access in this decade. • Mound has ~5 km of stratified rock. (That’s 3 miles!) • There is no evidence that volcanism ever occurred in Gale. • Mound materials were deposited as sediment. • Diverse materials are present. • Diverse events are recorded. – Episodes of sedimentation and lithification and diagenesis. – Episodes of erosion, transport, and re-deposition of mound materials. 4th MSL Landing Site Workshop, 27–29 September 2010 Edgett, 2 Gale is at ~5°S on the “north-south dichotomy boundary” in the Aeolis and Nepenthes Mensae Region base map made by MSSS for National Geographic (February 2001); from MOC wide angle images and MOLA topography 4th MSL Landing Site Workshop, 27–29 September 2010 Edgett, 3 Proposed MSL Field Site In Gale Crater Landing ellipse - very low elevation (–4.5 km) - shown here as 25 x 20 km - alluvium from crater walls - drive to mound Anderson & Bell -
Supervolcanoes Within an Ancient Volcanic Province in Arabia Terra, Mars 2 3 4 Joseph
EMBARGOED BY NATURE 1 1 Supervolcanoes within an ancient volcanic province in Arabia Terra, Mars 2 3 4 Joseph. R. Michalski 1,2 5 1Planetary Science Institute, Tucson, Arizona 85719, [email protected] 6 2Dept. of Earth Sciences, Natural History Museum, London, United Kingdom 7 8 Jacob E. Bleacher3 9 3NASA Goddard Space Flight Center, Greenbelt, MD, USA. 10 11 12 Summary: 13 14 Several irregularly shaped craters located within Arabia Terra, Mars represent a 15 new type of highland volcanic construct and together constitute a previously 16 unrecognized martian igneous province. Similar to terrestrial supervolcanoes, these 17 low-relief paterae display a range of geomorphic features related to structural 18 collapse, effusive volcanism, and explosive eruptions. Extruded lavas contributed to 19 the formation of enigmatic highland ridged plains in Arabia Terra. Outgassed sulfur 20 and erupted fine-grained pyroclastics from these calderas likely fed the formation of 21 altered, layered sedimentary rocks and fretted terrain found throughout the 22 equatorial region. Discovery of a new type of volcanic construct in the Arabia 23 volcanic province fundamentally changes the picture of ancient volcanism and 24 climate evolution on Mars. Other eroded topographic basins in the ancient Martian 25 highlands that have been dismissed as degraded impact craters should be 26 reconsidered as possible volcanic constructs formed in an early phase of 27 widespread, disseminated magmatism on Mars. 28 29 30 EMBARGOED BY NATURE 2 31 The source of fine-grained, layered deposits1,2 detected throughout the equatorial 32 region of Mars3 remains unresolved, though the deposits are clearly linked to global 33 sedimentary processes, climate change, and habitability of the surface4. -

Martian Crater Morphology
ANALYSIS OF THE DEPTH-DIAMETER RELATIONSHIP OF MARTIAN CRATERS A Capstone Experience Thesis Presented by Jared Howenstine Completion Date: May 2006 Approved By: Professor M. Darby Dyar, Astronomy Professor Christopher Condit, Geology Professor Judith Young, Astronomy Abstract Title: Analysis of the Depth-Diameter Relationship of Martian Craters Author: Jared Howenstine, Astronomy Approved By: Judith Young, Astronomy Approved By: M. Darby Dyar, Astronomy Approved By: Christopher Condit, Geology CE Type: Departmental Honors Project Using a gridded version of maritan topography with the computer program Gridview, this project studied the depth-diameter relationship of martian impact craters. The work encompasses 361 profiles of impacts with diameters larger than 15 kilometers and is a continuation of work that was started at the Lunar and Planetary Institute in Houston, Texas under the guidance of Dr. Walter S. Keifer. Using the most ‘pristine,’ or deepest craters in the data a depth-diameter relationship was determined: d = 0.610D 0.327 , where d is the depth of the crater and D is the diameter of the crater, both in kilometers. This relationship can then be used to estimate the theoretical depth of any impact radius, and therefore can be used to estimate the pristine shape of the crater. With a depth-diameter ratio for a particular crater, the measured depth can then be compared to this theoretical value and an estimate of the amount of material within the crater, or fill, can then be calculated. The data includes 140 named impact craters, 3 basins, and 218 other impacts. The named data encompasses all named impact structures of greater than 100 kilometers in diameter. -

Crater Geometry and Ejecta Thickness of the Martian Impact Crater Tooting
Meteoritics & Planetary Science 42, Nr 9, 1615–1625 (2007) Abstract available online at http://meteoritics.org Crater geometry and ejecta thickness of the Martian impact crater Tooting Peter J. MOUGINIS-MARK and Harold GARBEIL Hawai‘i Institute of Geophysics and Planetology, University of Hawai‘i, Honolulu, Hawai‘i 96822, USA (Received 25 October 2006; revision accepted 04 March 2007) Abstract–We use Mars Orbiter Laser Altimeter (MOLA) topographic data and Thermal Emission Imaging System (THEMIS) visible (VIS) images to study the cavity and the ejecta blanket of a very fresh Martian impact crater ~29 km in diameter, with the provisional International Astronomical Union (IAU) name Tooting crater. This crater is very young, as demonstrated by the large depth/ diameter ratio (0.065), impact melt preserved on the walls and floor, an extensive secondary crater field, and only 13 superposed impact craters (all 54 to 234 meters in diameter) on the ~8120 km2 ejecta blanket. Because the pre-impact terrain was essentially flat, we can measure the volume of the crater cavity and ejecta deposits. Tooting crater has a rim height that has >500 m variation around the rim crest and a very large central peak (1052 m high and >9 km wide). Crater cavity volume (i.e., volume below the pre-impact terrain) is ~380 km3 and the volume of materials above the pre-impact terrain is ~425 km3. The ejecta thickness is often very thin (<20 m) throughout much of the ejecta blanket. There is a pronounced asymmetry in the ejecta blanket, suggestive of an oblique impact, which has resulted in up to ~100 m of additional ejecta thickness being deposited down-range compared to the up-range value at the same radial distance from the rim crest. -

Dark Dunes on Mars
CHAPTER II: PLANET MARS – THE BACKGROUND Like Earth, its neighbour planet, Mars, is a terrestrial planet with a solid surface, an atmosphere, two ice-covered pole caps, and not one but two moons (Phobos and Deimos). Some differences, such as a greater distance to the sun, a smaller diameter, a thinner atmosphere, and the longer duration of a year distinguish Mars from the Earth, not to forget the absence of life…so far. Nevertheless, there are many correlations between terrestrial and Martian geological and geomorphological processes, permitting researchers to apply knowledge from terrestrial studies more or less directly to Mars. However, a closer look reveals that the dissimilarities, though few, can make fundamental differences in process background and development. The following chapter provides a brief but necessary insight into the geological and physical background of this planet, imparting to the reader some fundamental knowledge about Mars, which is useful for understanding this work. Fig. 1 presents an impression of Mars viewed from space. Figure 1: The planet Mars: a global view (Viking 1 Orbiter mosaic [NASA]). Chapter II Planet Mars – The Background 5 Table 1 provides a summary of some major astronomical and physical parameters of Mars, giving the reader an impression of the extent to which they differ from terrestrial values.
