Aeolian_Features-Windstreaks.jpgMagellan Probe: radio image of Windstreaks132 visiteUn'immagine decisamente chiara e relativa a quel fenomeno che viene chiamato 'wind streaking' e che ci indica, fra l'altro, la direzione usuale dei venti e la capacità di resistenza che i rilievi oppongono ad essi.01/27/10 at 17:11wernazzo: ma quella cosa discoidale all'apice della scia...

Volcanoes-PIA00261.jpgVolcanoes in Guinevere Planitia (possible Natural Colors; credits: Dr Paolo C. Fienga - Lunexit Team)55 visiteThis image, with radar illumination from West to East, shows three unusual Volcanoes located in the Guinevere Planitia Lowland. At the center of the image is a large feature (approx. 50 Km or about31 miles in diameter) with an unusual shape; very round when viewed from above with steep slides and a flat top.
These Volcanoes are believed to be the result of relatively thick and sticky (viscous) Lava Flows that originated from a point source. Although a faint remnant of its original circular shape is preserved, the Northern Rim of this center Volcano has a steep Scarp.
The Scarp is probably the result of material that has slid away from the Volcano and subsequently has been covered by Lava Flows. This Volcano overlaps another feature to the South-West that is about 45 Km (approx. 28 miles) in diameter and disrupted by many fractures.
The South-Eastern Volcano (about 25 Km or approx. 15,5 miles in diameter) appears to be the highest of the three as its illuminated Western Edge has the brightest radar return. The scalloped Edges give this feature a bottlecap-like appearance. The highly scalloped Edges are probably the result of multiple material slides along the Volcano Margin.MareKromium12/29/09 at 17:11MareKromium: ATTENZIONE: questo tipo di colorizzazione ? assolu...

Venusian_Surface-Venera_14-00.jpgVenus from Venera 14 (camera 1)128 visite"...The quality (of the Venera frames) is remarkably good, and a nearly perfect transmission can be compiled by carefully merging the information from multiple transmissions. A few sections appear damaged by noise, but these are actually bit synchronization errors which can be repaired in software. For example: work on this data set is in progress. Recovering the radiometric response function and balancing color are the next steps. Since the scene was scanned several times, it may be possible to calculate a super-resolution image from multiple panoramas, as NASA has done with Mars Pathfinder images..."12/14/09 at 16:49MareKromium: L'avremo!...Ma fra TANTO, TANTO, TANTO tempo.....
