  • Global Spectral Classification of Martian Low-Albedo Regions with Mars Global Surveyor Thermal Emission Spectrometer (MGS-TES) Data A
    JOURNAL OF GEOPHYSICAL RESEARCH, VOL. 112, E02004, doi:10.1029/2006JE002726, 2007 Global spectral classification of Martian low-albedo regions with Mars Global Surveyor Thermal Emission Spectrometer (MGS-TES) data A. Deanne Rogers,1 Joshua L. Bandfield,2 and Philip R. Christensen2 Received 4 April 2006; revised 12 August 2006; accepted 13 September 2006; published 14 February 2007. [1] Martian low-albedo surfaces (defined here as surfaces with Mars Global Surveyor Thermal Emission Spectrometer (MGS-TES) albedo values 0.15) were reexamined for regional variations in spectral response. Low-albedo regions exhibit spatially coherent variations in spectral character, which in this work are grouped into 11 representative spectral shapes. The use of these spectral shapes in modeling global surface emissivity results in refined distributions of previously determined global spectral unit types (Surface Types 1 and 2). Pure Type 2 surfaces are less extensive than previously thought, and are mostly confined to the northern lowlands. Regional-scale spectral variations are present within areas previously mapped as Surface Type 1 or as a mixture of the two surface types, suggesting variations in mineral abundance among basaltic units. For example, Syrtis Major, which was the Surface Type 1 type locality, is spectrally distinct from terrains that were also previously mapped as Type 1. A spectral difference also exists between southern and northern Acidalia Planitia, which may be due in part to a small amount of dust cover in southern Acidalia. Groups of these spectral shapes can be averaged to produce spectra that are similar to Surface Types 1 and 2, indicating that the originally derived surface types are representative of the average of all low-albedo regions.

A non-sun-synchronous orbit of Planet-B with a large eccentricity of about 0.87 around Mars provides the opportunities (1) to observe the same region of Mars at various times of day and various solar phase angles with spatial resolution of about 60 m from a distance of 150 km altitude (at periapsis), and (2) to monitor changes of global atmospheric conditions on Mars near an apoapsis of 15 Mars radii. In addition, (3) several encounters of Planet-B with each of the two Martian satellites are scheduled during the mission lifetime of two years from October 1999 to observe their shapes and surface structures with three color filters, centered on 450, 550, and 650 nm.

  • The Sand Ships of Mars By: Jeffrey D
    The Sand Ships of Mars By: Jeffrey D. Beish (Rev. 12-19-2018) INTRODUCTION It was Ray Bradbury who wrote of the "Sand Ships of Mars" in his science fiction novel, The Martian Chronicles (Bradbury, 1950). One can imagine the fictional inhabitants of Mars trekking across its deserts in their floating machines stirring up huge dust devils. This great science fiction story set the stage for this author’s interest in Mars and who now writes about similar accounts of the real dusty whirlwinds on the Red Planet. [NOTE: see Mars Chart in Reference section for location names]. One of the most spectacular events to watch in our Solar System is the development of a major Martian dust storm. From Earth a Martian dust cloud may seem to be just a nuisance to any would-be telescopic explorer on that planet. However, if you consider the actual size of these clouds then you suddenly realize that many of them would cover entire western United States! Imagine if a Mars-sized planet-encircling dust storm would occur on Earth; it would blank out most of an entire Hemisphere! Some would-be Mars experts claim that after dust storms the dust settles quickly to the surface and reduces contrast of albedo features. This is contrary to the known facts; dust remains in the atmosphere of Mars for weeks -- at times months -- before settling to the surface [Pollack, 1989], [Kahn, 1992]. This dust is very fine particles of volcanic ash and when raised aloft during these storms they reach heights of several kilometers.

  • The Opposition of Mars, 1999
    The opposition of Mars, 1999 Richard McKim A report of the Mars Section (Director: R. J. McKim) The 1999 martian apparition was followed by BAA members while Mars Global Surveyor was monitoring the planet from martian orbit. The planet’s surface showed little change from 1997, indicating the absence of any great dust storm since solar conjunction. The long period of telescopic coverage enabled us to conclude that neither was there any planet-encircling storm in the southern martian spring or summer in 1999−2000. Three small telescopic storms were followed along the Valles Marineris, and two were seen at the edge of the summer N. polar cap. Dust storms commencing at the historically rarely-active Margaritifer Sinus emergence site (MGS data) point to ongoing changes in the fallout pattern of atmospheric dust. White cloud activity was high before and around opposition time − in northern midsummer − with morning and evening limb hazes, the equatorial cloud band (ECB) and orographic clouds. The ECB ‘season’ was identical to 1997, pointing to an equally low level of atmospheric dust-loading. Comparison with historical records suggests that the seasonal ‘wave of darkening’ may be partly attributable to the annual disappearance of the ECB. A ‘polar cyclone’ imaged by the Hubble Space Telescope between Mare Acidalium and the northern cap was followed over several days. The seasonal behaviour of the NPC, including its transition to the polar hood, was well observed. Its recession (observed from northern mid-spring) was a little slower than usual. The formation of the SPC from its winter hood, and its early recession, was also recorded.

  • The Medusae Fossae Formation As the Single Largest Source of Dust on Mars
    ARTICLE DOI: 10.1038/s41467-018-05291-5 OPEN The Medusae Fossae Formation as the single largest source of dust on Mars Lujendra Ojha1, Kevin Lewis1, Suniti Karunatillake 2 & Mariek Schmidt3 Transport of fine-grained dust is one of the most widespread sedimentary processes occurring on Mars today. In the present climate, eolian abrasion and deflation of rocks are likely the most pervasive and active dust-forming mechanism. Martian dust is globally 1234567890():,; enriched in S and Cl and has a distinct mean S:Cl ratio. Here we identify a potential source region for Martian dust based on analysis of elemental abundance data. We show that a large sedimentary unit called the Medusae Fossae Formation (MFF) has the highest abundance of S and Cl, and provides the best chemical match to surface measurements of Martian dust. Based on volume estimates of the eroded materials from the MFF, along with the enrichment of elemental S and Cl, and overall geochemical similarity, we propose that long-term deflation of the MFF has significantly contributed to the global Martian dust reservoir. 1 Department of Earth and Planetary Sciences, Johns Hopkins University, Baltimore, MD 21218, USA. 2 Department of Geology and Geophysics, Louisiana State University, Baton Rouge, LA 70803, USA. 3 Department of Earth Sciences, Brock University, St. Catharines, ON L2S 3A1, Canada.
