Kerb The Medusae Fossae Formation (MFF), covering about 2.1 10 km (with an estimated volume of 1.4 10 km) and straddling the equatorial region of Mars east of Tharsis, h...

Gale crater is a large impact with ca 5 km thick sequence of stratified rocks in it, expressed today as central eroded mound (i.e., Aeolis Mons informally named Mt. Sharp). A goal the current Mars Science Laboratory mission to investigate processes that deposited, lithified, and this fill. The Light-Toned Yardang Unit (LTYu) unit, subject present research, one geological units Mt Sharp. Our spe...

due to the hard climatic conditions of the yardang region in the lut desert, not much information about land surface temperatures of this region, one of the extremely arid cli-matic zones of iran, has been extracted. therefore, in this study in order to obtain some information about important surface features of the lut desert (marl, grey sand, bright sand and salt affected land), field tempera...

Introduction: Mars is host to a wide range of aeolian forms such as dunes, ripples, dust devils, dust storms, yardangs, and ventifacts. Large dune fields characterized by low albedos and large duneform sizes have been observed and occur mainly around the north polar cap and in the southern mid-latitudes. However, another morphologically and dimensionally distinct population of aeolian bedforms ...

Introduction: Outflow channels on Mars are formed by very energetic floods suggesting catastrophic episodes of concentrated water flows [1]. These floods comes from a gigantic release of water such as in terrestrial glacial surge, but their exact origin is debated. Outflow channels of the Xanthe Terra region east of the Tharsis area are all of the Late Hesperian epoch and their source regions a...

Physical characteristics of different features in desert is a reflection of severe thermal and climatic conditions. In this paper, diurnal surface temperature patterns of important surface features in Lut Desert were studied and the relationship among different surfaces analyzed. Diurnal trend in surface temperature of surface types, marl, dark sand, light sand, salt-affected soil, soul at 10 c...

Introduction: We have been investigating several independent data sets from recent Mars missions that provide evidence for a meters-thick, latitude-dependent surface layer [1, 2, 3]. Based on apparent physical properties observed in Mars Orbiter Camera (MOC) images and Mars Laser Altimeter (MOLA) data, and the distinct latitude dependence of these observations, we interpreted this to be an ice-...

abstract this paper presents a robust approach using artificial neural networks in the form of a self organizing map (som) as a semi-automatic method for analysis and identification of morphometric features in two completely different environments, the man and biosphere reserve “eastern carpathians” (central europe) in a complex mountainous humid area and yardangs in lut desert, iran, a hyper a...
