Crater Population and Resurfacing of the Martian North Polar Cap
Introduction: The Martian north polar residual cap (NRC) lies on top of the north polar layered deposits (NPLD). The NRC is about 1m thick and composed primarily of large-grained, dust-poor water ice [1]. The mass balance of the north polar cap is uncertain. Satellite imagery reveals small reversible changes in its extent on an interannual basis [2]. Images with a pixel scale of up to 0.25 m/pi...
متن کاملSelf-sustaining Mars colonies utilizing the North Polar Cap and the Martian atmosphere.
A revolutionary new concept for the early establishment of robust, self-sustaining Martian colonies is described. The colonies would be located on the North Polar Cap of Mars and utilize readily available water ice and the CO2 Martian atmosphere as raw materials to produce all of the propellants, fuel, air, water, plastics, food, and other supplies needed by the colony. The colonists would live...
متن کاملGlacial Flow Modeling of the Martian North Polar Layered Deposits
Introduction: Recent observations of the Martian North Polar Layered Deposits (NPLD) suggest that glacial flow may govern its large-scale evolution [1]. There are two basic glaciological questions of climatological importance: (1) How fast is the NPLD presently flowing? (2) And does the NPLD experience " ice ages " : i.e., episodes of glacial advance and retreat at other orbital epochs? To addr...
متن کاملFormation Constraints on Martian North Polar Volcanic Edifices
Terrestrial Subglacial Volcanism: Many terrestrial subglacial volcanic features have been identified in Iceland [1-3], British Columbia, Canada [4], the Tuva Republic, Russia [5], Alaska [6], and Antarctica [7]. These features are though to follow a typical sequence of events although interpretations and details may differ by author and/or location: a single volcanic vent or short fissure opens...
متن کاملStratigraphic Anomalies in the Martian North Polar Layered Deposits
Introduction: We have identified numerous examples of anomalous trough stratigraphy within the North Polar Layered Deposits (NPLD). According to the standard model of NPLD stratigraphy [1], troughs can be divided into three main units: (1) Layered Terrain, which exhibit fine-scale laminae upon equatorward-facing (EWF) trough slopes; (2) Banded Terrain, more diffuse layers located on poleward-fa...
