STRUCTURE & FUNDING The Greater Houston Convention and Visitors Bureau is a 501(c)6 nonprofit corporation. The GHCVB is a marketing and service organization with a budget presently comprised of certain reserved funds and private funds raised through a variety of sources including investments in events, membership dues, advertising and in-kind contributions. At the beginning of 2014, the GHCVB’s primary source of funding was from a contract with the City of Houston which was assigned to the Houston First Corporation, or HFC, in 2011 and expired June 30, 2014. This contract funded approximately 92% of the GHCVB’s budget from a tax on hotel/ motel occupancy within the incorporated boundaries of Houston, Texas. Upon expiration of the contract on June 30, 2014, the GHCVB and HFC boards approved a strategic realignment between the two organizations to create a more efficient approach to marketing and selling Houston to tourists and conventions. -
Underlying Structural Control of Small-Scale Faults and Fractures in West Candor Chasma, Mars C
JOURNAL OF GEOPHYSICAL RESEARCH, VOL. 117, E11001, doi:10.1029/2012JE004144, 2012 Underlying structural control of small-scale faults and fractures in West Candor Chasma, Mars C. Birnie,1 F. Fueten,1 R. Stesky,2 and E. Hauber3 Received 29 May 2012; revised 4 September 2012; accepted 18 September 2012; published 2 November 2012. [1] Orientations of small-scale faults and fractures within the interior layered deposits of West Candor Chasma were measured to investigate what information about the geologic history of Valles Marineris they can contribute. Deformational features were separated into six categories based on morphology and their orientations were analyzed. The elevations at which the deformational features formed are recorded, as a proxy for stratigraphic level. Deformational features occur over a continuous range of elevations and display regionally consistent preferred orientations, indicating their formation was controlled by a regional stress regime. The two most abundant preferred orientations of 35 and 110 are approximately parallel to the chasma walls and the inferred underlying normal faults. The alignment of three populations of small faults at 140, consistent with the morphology of release faults, indicates a large-scale fault underlying the southeastern border of Ceti Mensa. The preferred orientations imply these small-scale deformational features formed from a continuation of the same imposed stresses responsible for the formation of Valles Marineris, indicating these stresses existed past the formation of the interior layered deposits. The origins of a fourth preferred orientation of 70 is less clear but suggests the study area has undergone at least two periods of deformation. Citation: Birnie, C., F. -

Nüwa, a Self-Sustainable City State on Mars – Development Concept, Urban Design and Life Support
50th International Conference on Environmental Systems ICES-2021-225 12-15 July 2021 Nüwa, a self-sustainable city state on Mars – development concept, urban design and life support Gisela Detrell1 University of Stuttgart, Stuttgart, Germany Alfredo Muñoz2 ABIBOO Studio, New York, USA Miquel Banchs-Piqué3 University of Portsmouth, Portsmouth, UK Guillem Anglada4,5 Institut de Ciències de l'Espai/CSIC, Barcelona, Spain Institut d'Estudis Espacials de Catalunya (IEEC), Barcelona, Spain Philipp Hartlieb6 Montanuniversitaet Leoben, Leoben, Austria Miquel Sureda7 UPC-BarcelonaTECH, Barcelona, Spain Mars is one of the current targets for human space exploration. The first settlement will most likely include a small group of explorers, but with time, it is reasonable to assume that a city on Mars might grow and become a reality. Nüwa is a project of the Sustainable Off-world Network (SONet), a network of interdisciplinary and international professionals, dedicated to the development of sustainable human settlements beyond Earth. This project focuses on engineering and architecture, but also on sustainable growth planning of a society on the red planet. The design consists of five cities, with 200,000 inhabitants each. Different locations strategically selected ensure in-situ resource utilization. The city concept is based on a tunneling system on cliffs. The design of a big city in the harsh Mars environment poses several challenges and is a complex and broad task. Further research in all fields is required. This paper focuses on three aspects of the design: development concept, urban planning and Life Support. The city needs to provide a safe environment for the inhabitants, but also provide all required services and a practical and enjoyable place to live. -

Sulfur on Mars from the Atmosphere to the Core Heather B
Sulfur on Mars from the Atmosphere to the Core Heather B. Franz1, Penelope L. King2, and Fabrice Gaillard3 1NASA Goddard Space Flight Center, Greenbelt, MD 20771, USA 2Research School of Earth Sciences, Australian National University, Canberra ACT 2601, Australia 3CNRS-Université d’Orléans, ISTO, la rue de la Ferollerie, 45071 Orléans, France Abstract Observations of the martian surface from orbiting spacecraft and in situ landers and rovers, as well as analyses of martian meteorites in terrestrial laboratories, have consistently indicated that Mars is a sulfur-rich planet. The global inventory of sulfur, from the atmosphere to the core, carries widespread implications of potential geophysical, geochemical, climatological, and astrobiological significance. For example, the sulfur content of the core carries implications for core density; the speciation of igneous sulfur minerals reflects the oxidation state of the magma from which they formed; sulfur-bearing gases may have exerted control on the temperatures at the surface of early Mars; and the widespread availability of sulfur on Mars would have provided an abundant source for energy and nutrients to fuel sulfur-metabolizing microbes, such as those that arose during the emergence of primitive life on Earth. Here we provide an overview of martian sulfur and its relevance to these areas of interest, including a discussion of analytical techniques and results acquired by space missions and meteorite analyses to date. We review current studies modeling the potential effects of sulfur-bearing gases on the past martian climate and possible constraints on atmospheric composition implied by sulfur isotopic data. We also explore the importance of sulfur to the search for extinct or extant life on Mars. -

Evolution of Major Sedimentary Mounds on Mars: Build-Up Via Anticompensational Stacking Modulated by Climate Change
Evolution of major sedimentary mounds on Mars: build-up via anticompensational stacking modulated by climate change Edwin S. Kite1,*, Jonathan Sneed1, David P. Mayer1, Kevin W. Lewis2, Timothy I. Michaels3, Alicia Hore4, Scot C.R. Rafkin5. 1. University of Chicago. 2. Johns Hopkins University. 3. SETI Institute. 4. Brock University. 5. Southwest Research Institute. (*[email protected]) Abstract. We present a new database of >300 layer-orientations from sedimentary mounds on Mars. These layer orientations, together with draped landslides, and draping of rocks over differentially- eroded paleo-domes, indicate that for the stratigraphically-uppermost ~1 km, the mounds formed by the accretion of draping strata in a mound-shape. The layer-orientation data further suggest that layers lower down in the stratigraphy also formed by the accretion of draping strata in a mound-shape. The data are consistent with terrain-influenced wind erosion, but inconsistent with tilting by flexure, differential compaction over basement, or viscoelastic rebound. We use a simple landscape evolution model to show how the erosion and deposition of mound strata can be modulated by shifts in obliquity. The model is driven by multi-Gyr calculations of Mars’ chaotic obliquity and a parameterization of terrain-influenced wind erosion that is derived from mesoscale modeling. Our results suggest that mound-spanning unconformities with kilometers of relief emerge as the result of chaotic obliquity shifts. Our results support the interpretation that Mars’ rocks record intermittent liquid-water runoff during a 108-yr interval of sedimentary rock emplacement. 1. Introduction. Understanding how sediment accumulated is central to interpreting the Earth’s geologic records (Allen & Allen 2013, Miall 2010). -
