The mosaics of Mars: As seen by the Viking Lander cameras [PDF]

open access: yes
The mosaics and derivative products produced from many individual high resolution images acquired by the Viking Lander Camera Systems are described: A morning and afternoon mosaic for both cameras at the Lander 1 Chryse Planitia site, and a morning, noon,

A preliminary approach towards a logic for warrant [PDF]

open access: yes, 2014
We extend Defeasible Logic Programming for it to be able to warrant complex logical formulas. We show how negation, conjunction, disjunction and implication of ground literals can be tested for warrant.

Ice-Enriched Loess and the Formation of Periglacial Terrain in Mid-Utopia Planitia, Mars [PDF]

open access: yes, 2012
Landforms suggestive of periglacial processes are commonplace in mid-Utopia Planitia, Mars. They form syngenetically in ground-ice comprised of loess transported by katabatic wind from the NPLDs and enriched by ice through the thaw-freeze cycling of ...

Statistics of Mars' topography from the Mars Orbiter Laser Altimeter: Slopes, correlations, and physical Models [PDF]

open access: yes, 2001
Data obtained recently by the Mars Orbiter Laser Altimeter (MOLA) were used to study the statistical properties of the topography and slopes on Mars. We find that the hemispheric dichotomy, manifested as an elevation difference, can be described by long ...

Plutos Far Side [PDF]

open access: yesarXiv, 2019
The New Horizons spacecraft provided near global observations of Pluto that far exceed the resolution of Earth-based data sets. Most Pluto New Horizons analysis hitherto has focused on the encounter hemisphere of Pluto (i.e., the antiCharon hemisphere containing Sputnik Planitia). In this work, we summarize and interpret data on the far side (i.e., the

Martian clouds observed by Mars Global Surveyor Mars Orbiter Camera [PDF]

open access: yes, 2002
We have made daily global maps that cover both polar and equatorial regions of Mars for Ls 135°–360° and 0°–111° using the Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) red and blue wide-angle swaths taken from May 1999 to January 2001.
