Wednesday April 26, 2017 R E L A T E D A STEp TOWARD MARS A R T I C L E S A highly successful test of a prototype power generator Come on at the University of Dayton Research Institute bodes well for NASA's plans to expand its exploration of Mars over Mars with the next rover mission. Rover In early February, NASA scientists narrowed down potential landing sites for Mars 2020 to three — Northeast Syrtis, Jezero Crater and Columbia Hills — at least one of which is likely to be warmer than sites where previous rovers landed. Simultaneously, researchers in Dayton performed a high-temperature qualifying test on a power generator prototype to see if it would operate successfully at the higher temperatures that may be experienced by the generator powering the next rover. The Mars 2020 rover will be powered by a Multi-Mission Radioisotope Thermoelectric Generator (MMRTG) — similar to the unit currently providing power to Curiosity in Gale Crater — which converts heat created by naturally decaying plutonium radioisotopes into electricity to power the rover's instruments, computers, wheels, robotic arm and radio. -
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. -

Discrete Element Modelling of Pit Crater Formation on Mars
geosciences Article Discrete Element Modelling of Pit Crater Formation on Mars Stuart Hardy 1,2 1 ICREA (Institució Catalana de Recerca i Estudis Avançats), Passeig Lluís Companys 23, 08010 Barcelona, Spain; [email protected]; Tel.: +34-934-02-13-76 2 Departament de Dinàmica de la Terra i de l’Oceà, Facultat de Ciències de la Terra, Universitat de Barcelona, C/Martí i Franqués s/n, 08028 Barcelona, Spain Abstract: Pit craters are now recognised as being an important part of the surface morphology and structure of many planetary bodies, and are particularly remarkable on Mars. They are thought to arise from the drainage or collapse of a relatively weak surficial material into an open (or widening) void in a much stronger material below. These craters have a very distinctive expression, often presenting funnel-, cone-, or bowl-shaped geometries. Analogue models of pit crater formation produce pits that typically have steep, nearly conical cross sections, but only show the surface expression of their initiation and evolution. Numerical modelling studies of pit crater formation are limited and have produced some interesting, but nonetheless puzzling, results. Presented here is a high-resolution, 2D discrete element model of weak cover (regolith) collapse into either a static or a widening underlying void. Frictional and frictional-cohesive discrete elements are used to represent a range of probable cover rheologies. Under Martian gravitational conditions, frictional-cohesive and frictional materials both produce cone- and bowl-shaped pit craters. For a given cover thickness, the specific crater shape depends on the amount of underlying void space created for drainage. -

Stern | Geological Sciences Fran Bagenal | Astrophysical and Planetary Sciences Stephen J. Mojzsis | Geological Sciences ABSTRACT' Arabia Terra, a region in the northern hemisphere of Mars, has puzzled planetary scientists because of its odd assemblage of characteristics. This makes the region difficult to categorize, much less explain. Over the past few decades, several hypotheses for the geological history of Arabia Terra have been posited, but so far none are conclusive. For this study, a subset of the Mars crater database [Robbins and Hynek, 2012a] was reprocessed using a new algorithm [Robbins and Hynek, 2013]. Each hypothesis’s effect on the crater population was predicted, then tested via several crater population characteristics including cumulative size-frequency distribution, depth-to-diameter ratio, and rim height. -
The Deposition and Alteration History of the Northeast Syrtis Major Layered Sulfates
The deposition and alteration history of the northeast Syrtis Major layered sulfates Daven P. Quinn1 and B.L. Ehlmann1,2 1Division of Geological and Planetary Sciences, California Institute of Technology, Pasadena, California, USA 2Jet Propulsion Laboratory, California Institute of Technology, Pasadena, California, USA October 12, 2018 Abstract The ancient stratigraphy on the western margin of the Isidis basin records the history of wateron early Mars. Noachian units are overlain by layered, basaltic-composition sedimentary rocks that are enriched in polyhydrated sulfates and capped by more resistant units. The layered sulfates – uniquely exposed at northeast Syrtis Major – comprise a sedimentary sequence up to 600-m thick that has undergone a multi-stage history of deposition, alteration, and erosion. Siliciclastic sed- iments enriched in polyhydrated sulfates are bedded at m-scale and were deposited on slopes up to 10°, embaying and thinning against pre-existing Noachian highlands around the Isidis basin rim. The layered sulfates were then modified by volume-loss fracturing during diagenesis, and the fractures hosted channelized flow and jarosite mineral precipitation to form resistant ridges upon erosion. The depositional form and diagenetic volume-loss recorded by the layered sulfates suggest deposition in a deepwater basin. After their formation, the layered sulfates were first capped by a “smooth capping unit” and then eroded to form paleovalleys. Hesperian Syrtis Ma- jor lavas were channelized by this paleotopography, capping it in some places and filling it in others. Later fluvial features and phyllosilicate-bearing lacustrine deposits, which share a con- sistent regional base level (~-2300 m), were superimposed on the sulfate-lava stratigraphy. -

Abstract STUBBLEFIELD, RASHONDA KIAM. Extensional Tectonics at Alba Mons, Mars
Abstract STUBBLEFIELD, RASHONDA KIAM. Extensional Tectonics at Alba Mons, Mars: A Case Study for Local versus Regional Stress Fields. (Under the direction of Dr. Paul K. Byrne). Alba Mons is a large shield volcano on Mars, the development of which appears to be responsible for tectonic landforms oriented radially and circumferentially to the shield. These landforms include those interpreted as extensional structures, such as normal faults and systems of graben. These structures, however, may also be associated with broader, regional stress field emanating from the volcano-tectonic Tharsis Rise, to the south of Alba Mons and centered on the equator. In this study, I report on structural and statistical analyses for normal faults proximal to Alba Mons (in a region spanning 95–120° W and 14–50° N) and test for systematic changes in fault properties with distance from the volcano and from Tharsis. A total of 11,767 faults were mapped for this study, and these faults were all measured for strike, length, and distance from Alba Mons and Tharsis. Additional properties were qualitatively and quantitatively analyzed within a subset of 62 faults, and model ages were obtained for two areas with crater statistics. Distinguishing traits for each structure population include fault properties such as strike, vertical displacement (i.e., throw) distribution profiles, displacement–length (Dmax/L) scaling, and spatial (i.e., cross-cutting) relationships with adjacent faults with different strikes. The only statistically significant correlation in these analyses was between study fault strike with distance from Tharsis. The lack of trends in the data suggest that one or more geological processes is obscuring the expected similarities in properties for these fault systems, such as volcanic resurfacing, mechanical restriction, or fault linkage. -

James2 V Infinity Research LLC. – Altadena, CA, USA Kris Zacny,3 Philip Chu, Jack Craft Honeybee Robotics Spacecraft Mechanisms Corporation – Pasadena, CA, USA This paper presents the results from the nine-month, Phase 1 investigation for the Robotic Asteroid Prospector (RAP). This project investigated several aspects of developing an asteroid mining mission. It conceived a Space Infrastructure Framework that would create a demand for in space-produced resources. The resources identified as potentially feasible in the near-term were water and platinum group metals. The project’s mission design stages spacecraft from an Earth Moon Lagrange (EML) point and returns them to an EML. The spacecraft’s distinguishing design feature is its solar thermal propulsion system (STP) that provides two functions: propulsive thrust and process heat for mining and mineral processing. The preferred propellant is water since this would allow the spacecraft to refuel at an asteroid for its return voyage to Cis- Lunar space thus reducing the mass that must be launched from the EML point. The spacecraft will rendezvous with an asteroid at its pole, match rotation rate, and attach to begin mining operations. The team conducted an experiment in extracting and distilling water from frozen regolith simulant.
