OPP-SOL1475-VictoriaClouds.gifClouds over Victoria Crater (GIF-Movie)58 visiteOpportunity turned its "Rover Eyes" skyward to observe clouds drifting overhead that look like cirrus clouds on Earth - featherlike formations composed mostly of ice crystals.
By looking at the clouds, Opportunity learns about seasonal and daily weather patterns on Mars. Scientists want to understand how water vapor is transported around the Planet. For example, on the extremely cold Red Planet, surface ice warmed by Sunlight can briefly turn to vapor that rises into the atmosphere and then quickly cools to form ice crystals again, either in clouds or back on the ground. Scientists also estimate wind speed and direction based on the movement of the clouds. It definitely gives you the sense of what it might feel like to sit back and watch clouds on Mars.MareKromium

Gravitational_Lensing-01.jpgGravitational Lensing and "Light Distortion"58 visite"...Noi continuiamo a definire, reputare e trattare il Tempo e lo Spazio come ed in quanto Misure Lineari.
Questo, a mio parere, equivale a dire che non solo le nostre "basi" sono fatiscenti, ma altresì che noi non abbiamo la minima idea di che cosa il Tempo e lo Spazio sìano effettivamente...
Comunque sia, dobbiamo aspettare. La Verità, nella Vita come nella Scienza, alla fine si automanifesta e si dimostra da sola, nonostante tutto e tutti..."

PSP_007547_1895_RED_abrowse-01.jpgRolling Rocks inside Shalbatana Vallis (EDM - False Colors; credits: Dr Paolo C. Fienga - Lunexit Team)58 visiteIn this extra-detail mgnf, the left frame shows boulders moving in two directions, indicating that they had different sources.
The right frame shows a boulder about 4 meters in diameter in the bottom left, having left a track that begins in the upper right. This boulder rolled down the hill, appears to have jumped the crater, bounced a few times, and then rolled to a halt.MareKromium

PSP_007653_2010_RED_abrowse-00.jpgBright on Dark (MULTISPECTRUM; credits: Lunexit)58 visiteThis image reveals bright Slope Streaks in Bahram Vallis, a long sinuous valley that winds across North-Eastern Lunae Planum and Xanthe Terra to the circum-Chyrse basin.
Typically, dark and light-toned Slope Streaks appear together on light-toned slopes. This scene is a rare case in which only bright streaks are visible on a dark surface. Slope Streaks generally start at a point source and widen downslope as a single streak or branch into multiple streaks. Some of the Slope Streaks show evidence that downslope movement is being diverted around obstacles, such as large boulders, and a few appear to originate at boulders or clumps of rocky material.
Many hypotheses have been proposed for the formation of slope streaks including dry avalanching, geochemical weathering, liquid stains or flows, and moisture wickering. Recent observations from HiRISE images have revealed that the interior of Slope Streaks is lower in elevation than the surroundings indicating that material must have been removed and then deposited in the formation of the streak.
Slope Streak formation is among the few known processes currently active on Mars. Where they appear together, dark Slope Streaks cross cut and lie on top of the older and lighter-toned streaks leading to the belief that lighter-toned streaks are dark streaks that have lightened with time as new dust settled on their surface. Over the course of several years, MOC images from this Region did not reveal any new dark or light-toned Slope Streaks suggesting that streak formation is not currently active here.
HiRISE will continue to monitor this Region for new slope streaks and changes in tone of old streaks.MareKromium

PrometheiPlanum.jpgPromethei Terra (Natural Colors + MULTISPECTRUM; credits: ESA & Lunexit)58 visitePromethei Planum, an area seasonally covered with layer of ice more than 3500 mt thick layer of ice in the Martian South Polar Region, was the subject of the High Resolution Stereo Camera’s focus on 22 September 2005 as Mars Express was in orbit above the Red Planet.
Promethei Planum lies at approx. 76° South Lat. and 105° East Long.
An approx. 100 Km-large and 800 mt-deep impact crater is visible in the Northern part of the image. The crater’s interior is partly covered in ice.
In the centre of the image are structures that may have been created by basaltic lava flow from a volcano. This area is covered in ice. The dark dunes towards the bottom of the image are most likely made up of dust originating from this lava flow or volcanic ash.
A broad sheet of ice, which is an extension of the South Polar Ice Cap is located South of the lava flow. The steep flanks clearly show white, clean ice. The thickness of the ice is between 900 and 1100 mt.MareKromium
