Dr. Tom Watters http://www.nasm.si.edu/research/ceps/research/mars/dichotomy_devel.cfm Mars Research in CEPS (Center of Earth and Planetary Studies) http://www.nasm.si.edu/research/ceps/research/mars/mars.cfm Mars is the fourth planet from the Sun and in many ways displays a "split personality" with respect to its geologic history. On the one hand, the planet retains a thin atmosphere, has large polar caps, and displays evidence that water has flowed and may have ponded on the surface. In these respects, Mars appears to be fairly Earth-like. On the other hand, the planet is variably cratered and large sections have been resurfaced by volcanic activity that give a more Moon-like impression. Although Mars only has about 11% of the mass of the Earth and only 38% of the surface gravity, it is a strange and diverse planet. For example, the land surface area is approximately equivalent to that exposed above sea level on the Earth and topography ranges some 35 km from the depths of the largest impact basin in the solar system (Hellas basin) to the top of the largest known volcano (Olympus Mons). In addition, there are enormous outflow channels that record the past discharge of floods from the more elevated and ancient southern cratered highlands into the lower and relatively younger northern lowlands. A gigantic canyon stretches thousands of kilometers across the equator of the planet and cuts kilometers into the crust while extensive outpourings of lava have buried broad portions of the surface. Nearly everywhere, a variable density of impact craters provides a means for constraining the relative timing of these events Age and Characteristics of Martian Valley Networks. Dr. Robert Craddock http://www.nasm.si.edu/research/ceps/research/mars/craddock_mvn.cfm goal is to determine when valley network were forming and to locate the oldest and most long-lived fluvial systems on Mars Ancient Water Systems on Mars. Dr. John Grant http://www.nasm.si.edu/research/ceps/research/mars/water_systems.cfm Ascraeus Mons Lava Flow, William Brent Garry http://www.nasm.si.edu/research/ceps/research/mars/ascraeus_mons.cfm The Ascraeus Mons lava flow is situated in the saddle region between Pavonis Mons and Ascraeus Mons. The source volcano, Ascraeus Mons, is one of the four large Tharsis shield volcanoes and measures 375 km by 870 km at the base and is 15 km high. Degradation of Victoria Crater, Mars. Dr. John Grant http://www.nasm.si.edu/research/ceps/research/mars/victoria_crater.cfm Geologic Mapping of Mars.

Dr. Ross Irwin http://www.nasm.si.edu/research/ceps/research/mars/fluvial_processes.cfm Light-toned layered deposits in Crater Terby and the greater Hellas Region, Mars.Sharon Wilson Purdy http://www.nasm.si.edu/research/ceps/research/mars/crater_terby.cfm Mars Rover Results.Dr. John Grant http://www.nasm.si.edu/research/ceps/research/mars/mars_rover_results.cfm The Mars rovers Spirit and Opportunity are acting as ground-truth operators, remotely manned by the researchers to explore the Martian terrain. A lengthy process for determining the rover landing sites, conducted by the Mars landing site steering committee co-chaired by Dr. Grant, culminated in the selection of Gusev Crater and Meridiani Terra. Speculation about the potential for ancient water processes at these two locations based on the analysis of remotely sensed imagery drove the selection of these two locations. Husband Hill, SE of the Gusev plains, represents an older geological feature within the crater compared to the surrounding Hesperian-aged plains. Husband Hill is characterized by exposed bedrock and an absence of thick regolith3, opposite of the Gusev plains. Additionally, the hill experiences higher rates of eolian erosion on the order of meters to tens of meters compared the tens of centimeters typifying much of the plains3. Some limited alteration of a few local rock outcroppings is observed, but there is no evidence for surface water in eroding the current landscape. Home plate, a plateau 2-3 m high located within the Inner basin of Columbia hills and SE of Husband Hill, reveals a terrain more modified by explosive volcanism than impacts4. Rock outcrops differ slightly from the basaltic rocks strewn across the previous Gusev locations due to their higher amounts of trace elements (Cl, Br, Zn, and Ge) Martian TARs. Dr. Jim Zimbelman http://www.nasm.si.edu/research/ceps/research/mars/martian_tars.cfm Modification of Martian Impact Craters. Dr. Robert Craddock http://www.nasm.si.edu/research/ceps/research/mars/craddock_cratermod.cfm Impact craters have fairly simple, geometric shapes that easily lend themselves to both qualitative and quantitative analyses. Impact craters have also formed throughout the entire history of Mars. By carefully analyzing the geology and physical structure of fresh and modified impact craters in the highlands, it will be possible to deconvolve the types and intensity of geologic processes that have operated through time on Mars. While similar analyses have been undertaken from Mariner and Viking orbiter data, our understanding of the geologic history recorded in modified impact craters is, at best, crude. High-resolution imagery from Mars Global Surveyor (MGS), Mars Odyssey (MO), and Mars Express (MEX) provide unprecedented details of not only the fluvial processes that extensively modified impact craters early in martian history, but also information about the processes that have operated on Mars to the present day. Mars Orbiter Laser Altimetry (MOLA) topographic data can also provide detailed morphometric information about modified crater shape, which is necessary for estimating the amount of erosion that has occurred. Through analyses of available imagery, remote sensing, and topographic data we will Paleolakes on Mars. Dr. Ross Irwin http://www.nasm.si.edu/research/ceps/research/mars/paleolakes.cfm QCD Discoveries Shed New Light on Northern Lowlands Geological age.Dr. Thomas Watters http://www.nasm.si.edu/research/ceps/research/mars/qcd.cfm Shorelines on Mars. Dr. Jim Zimbelman http://www.nasm.si.edu/research/ceps/research/mars/martian_shorelines.cfm Some planetary geologists infer that an ancient northern lowland-filled ocean once existed on Mars. As a result, this hypothesis has been repeatedly tested using numerous techniques and methods, culminating in very mixed results. Like many geologists before them, a team including Dr. Zimbelman finally took their turn at the wheel. Even though their new path yielded similarly inconclusive results, they provided ramifications for future studies in their wake This study looked for shorelines accompanying features such as barrier ridges/islands, beach ridges, spits, and looped barriers1 instead of searching for the shoreline itself. Out of the 447 THEMIS VIS and 735 MOC NA images examined, only four showed potential for these shoreline complimentary features1, one of which is featured above. Instead of ruling out the possibility of an ancient ocean once existing, five possible scenarios are identified explaining their results. These scenarios range from arguing an ocean never existed to justifying that it did exist and explaining why there is a lack of evidence1 today. Though no definite yes/no answer to the ''Did an ancient ocean exist?'' question was determined from the study, it does provide a good stepping point for future investigation. Terrestrial Analogues. Dr. Jim Zimbelman http://www.nasm.si.edu/research/ceps/research/mars/terrestrial_analogues.cfm Volcanic features of New Mexico analogous to volcanic features on Mars," details comparisons made between various New Mexico volcanic features with related Martian examples. New Mexico represents an arid environment with an extensional rift setting, and a wide range of both type and age of volcanoes with a fabulous array of particularly young volcanic features1, all aspects characteristic of, or aiding in the understanding of the degradation of Martian volcanic features. Specifically ash flows, calderas, large radial dikes, large lava flows, flow fields, and hydromagmatic vents1 represent some of the volcanic features found in New Mexico that can be related to certain Martian rough equivalents Rare martian lake delta spotted by Mars Express http://www.esa.int/export/esaCP/SEMM71VTTRG_index_0.html New Evidence for Cold Ocean on Early Mars by Charles Q.
