Oxygen Isotopes and Volatiles in Martian Meteorite [PDF]

, 2013
Oxygen isotopes were measured in mineral separates from martian meteorites using laser fluorination and were found to be remarkably uniform in both δ18O and Δ17O, suggesting that martian magmas did not assimilate aqueously altered crust regardless of any

The Martian Satellites [PDF]

International Astronomical Union Colloquium, 1971
The Martian satellites are some of the most interesting and accessible objects in the solar system, and therefore worth studying or even visiting. As small bodies, on the order of kilometers in diameter (see table I), they may have experienced no internal heating or volcanism, and could therefore be original condensations in the solar system.

Icelandic analogs to Martian flood lavas [PDF]

, 2004
We report on new field observations from Icelandic lava flows that have the same surface morphology as many Martian flood lava flows. The Martian flood lavas are characterized by a platy-ridged surface morphology whose formation is not well understood ...

Shear-Induced ringwoodite formation in the Martian shergottite Dar al Gani 670 [PDF]

, 2013
Shock-produced melt veins in the Martian shergottite Dar al Gani 670 crosscut large olivine crystals. The upper part of one of these crystals appears to be sheared off and displaced along the shock vein.

Dark aeolian sediments in Martian craters: Composition and sources [PDF]

, 2011
Our research focuses on the mineralogical characteristics of dark sediment deposits in Martian craters (dunes, dune fields, and sand sheets) and their local sediment sources, carried out on the basis of 70 selected localities.

Processing by robust cepstral fractal - topological methods of flows of optical texture images of the martian surface

Eurasian Physical Technical Journal, 2019
The paper presents the results of applying digital image processing methods to improve their quality and intelligibility. The method is used to process images of Martian craters made by the famous American satellites Mariner and Viking.

IR SPECTRAL MAPPING OF THE MARTIAN SOUTH POLAR RESIDUAL CAP USING CRISM [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2016
Polycyclic aromatic hydrocarbons (PAHs) are considered to be important in theories of abiogenesis (Allamandola, 2011) . There is evidence that PAHs have been detected on two icy Saturnian satellites using the Visual and Infrared Mapping Spectrometer ...

Extraction of polar and nonpolar biomarkers from the martian soil using aqueous surfactant solutions [PDF]

, 2012
The Life Marker Chip intends to use an aqueous surfactant solution to extract both polar AND nonpolar biomarkers from the martian soil for transport to an antibody-based detection system. Currently, a solution of 1.5 g l-1 polysorbate 80 in 20:80 (vol:
