Cryptic_Terrain_on_Mars_(PSP_003179_0945)-1.jpgThese ARE NOT Trees! (Natural Colors; credits: Dr G. Barca & Lunar Explorer Italia)60 visiteUn altro "Mito" Marziano crolla miseramente grazie alle straordinarie ottiche della Sonda Mars Reconnaissance ed al formato JP2. I "Pioppi Marziani" - o, comunque, quei rilievi che svariati Esperti di Anomale Spaziali (da Hoagland al Dr Skipper) ritenevano essere delle INDISCUTIBILI EVIDENZE (!) di vegetazione locale - si rivelano per quel che sono: striature scure del suolo, di fatto assai simili ai Wind-Streaks, di cui condividono la Natura (eolica).
Adesso, come Giustizia, Onest Intellettuale e Buon Senso esigerebbero, noi ci aspetteremmo una piccola "apology" da parte dei fenomeni Skipper ed Hoagland, ma sappiamo benissimo che non verr...MareKromium

PIA10144-DarkFans~0.jpgBright Streaks and Dark Fans (MULTISPECTRUM; credits: Lunexit)53 visiteThe South Polar Region of Mars is covered every year by a layer of Carbon Dioxide (CO2) ice. In a Region called the "cryptic terrain", the ice is translucent and sunlight can penetrate through the ice to warm the surface below.
The ice layer sublimates (evaporates) from the bottom. The Dark Fans of dust seen in this image come from the surface below the layer of ice, carried to the top by gas venting from below. The translucent ice is "visible" by virtue of the effect it has on the tone of the surface below, which would otherwise have the same color and reflectivity as the Fans.
Bright streaks in this image are fresh frost. The CRISM team has identified the composition of these streaks to be Carbon Dioxide.
Nota Lunexit: questa la surface feature che ha "stimolato" l'immaginazione di Joseph Skipper e Richard Hoagland. Secondo costoro, le "dark features" sarebbero alberi simili ai "pioppi" terrestri... Ogni ulteriore commento ci sembra davvero inutile.MareKromium

PIA10145-CrypticTerrain~0.jpgCryptic Terrain (MULTISPECTRUM; credits: Lunexit)72 visiteThere is an enigmatic Region near the South Pole of Mars known as the "cryptic" terrain. It stays cold in the Spring, even as its albedo darkens and the Sun rises in the sky.
This Region is covered by a layer of translucent seasonal CO2 ice that warms and evaporates from below. As CO2 gas escapes from below the slab of seasonal ice it scours dust from the surface. The gas vents to the surface, where the dust is carried downwind by the prevailing wind.
The channels carved by the escaping gas are often radially organized and are known informally as "spiders". MareKromium

Venusian_Atmosphere-Airglow_VIRTIS_Anticlockwise-01.jpgThe "Airglow" of Venus53 visiteOne year has passed since 11 April 2006, when Venus Express, Europes first mission to Venus and the only spacecraft now in orbit around the planet, reached its destination. Since then, this advanced probe, born to explore one of the most mysterious planetary bodies in the Solar System, has been revealing planetary details never caught before.
Intensively visited by several Russian and American probes from the 60s to the early 90s, Venus has always represented a puzzling target for scientists worldwide to observe. Venus Express, designed and built in record time by ESA, was conceived with the purpose of studying Venus - unvisited since 1994 - in the most comprehensive and systematic way ever, to provide a long-due tribute to a planet so interesting, yet cryptic.
Using state-of-the-art instrumentation, Venus Express is approaching the study of Venus on a global scale. The space probe is collecting information about Venus noxious and restless atmosphere (including its clouds and high-speed winds, as seen from this video obtained with the VMC camera on board) and its interaction with the solar wind and the interplanetary environment. Last but not least, it is looking for signs of surface activity, such as active volcanism. MareKromium
