022-Mars_Water-1.jpgWhere is the "Water" of Mars? (Polar Regions)55 visiteWater abundances in the Martian Polar Regions, from the Neutron Spectrometer on Mars Odyssey, are shown here to complement the Mercator Projections of Equatorial Regions.
The North Pole is nearly pure water ice, while the South Pole is water iced mixed with other stuff, most likely dry ice (CO2) and mineral dust.
More details are available in the Los Alamos National Lab press release.MareKromium

014-Mars_Altitudes.jpgMars "Ups and Downs"...55 visiteThe MOLA Laser Altimeter produced detailed topographic maps and profiles of Mars, and really revolutionized our understanding of Mars.
So much from elevation alone!
These maps show the MOLA altitude data coded into colors - blue is low and red/white are high.MareKromium

015-Mars_Altitudes.jpgMars "Ups and Downs"... (shaded version)55 visiteHere, the MOLA Altimetry is cast as a 3-D model, a shaded relief map illuminated from the upper right.
BEWARE: this lighting can not ever happen on Mars!
The large volcanos stand out beautifully, as do the impact basins of Hellas and Argyre. Also clear here is how flat the Northern Plains really are (remnants of an ocean basin?), the incredible number of craters on the Highlands, and the distinct difference in elelvations between the Highlands and the Lowlands.MareKromium

013-Mars_Visual_Albedo_.jpgMars Visual Albedo through a RED Filter55 visiteThis image of Mars is from the Mars Orbiter Camera (MOC) on the Mars Global Surveyor (MGS) Spacecraft.
The image means the "Visual Brighness" of Mars, meaning how Mars would appear to the human eye through a red filter.
The mosaic is from a short time in 1999, when there was a significant dust storm in Hellas Basin (brigh spot on right side near bottom).
There is no data from the South Pole, because it was in total darkness at the time - and Mars' North Pole was pointed towards the Sun.MareKromium
