T-TRA_000830_1440_RED_NigerVallis_01.jpgNiger Vallis59 visiteThis image shows a portion of the floor of Niger Vallis, an ancient Martian outflow channel. Niger Vallis originates on the flanks of the volcano Hadriaca Patera, and empties into the Hellas impact basin. Outflow channels are observed in many regions of the planet, and may have been carved by brief eruptions of liquid water from beneath the surface. Since Niger Vallis formed, impacts have cratered the channel floor, and fine-grained wind-blown debris has been transported across the surface, eroding and burying all but the freshest craters. The curved ridge in the scene may be the remnant of a large crater rim. At the high resolution of this image, a pattern of parallel dunes and ripples can be seen, as well as individual boulders as large as two meters across.

Titan-Lakes-Unnamed_North_Polar_Lakes-02-PIA01942.jpgTitanian Northern Lakes (3)59 visiteCaption NASA originale:"Using its radar system, the Cassini spacecraft has imaged new lakes on Titan.
The large dark patch seen on this image, at high latitudes surrounding Titan's North Pole, is most likely a hydrocarbon lake. Several dark channels can be seen; the longest one at the left meanders over almost 100 Km (about 62 miles), and appears to drain into the lake. Some dark channels are remarkably straight, suggesting possible faulting in the subsurface. The bright landforms jutting into the lake indicate that old, eroded landforms may have flooded.
This radar image was acquired by the Cassini radar instrument in synthetic aperture mode on Oct. 9, 2006. The image is centered near 73° North Latitude and 343° West Longitude; it measures about 300 by 140 Km (such as about 190 by 90 miles). Smallest details in this image are about 500 mt (approx. 1.640 feet) across".

Still hesitating,
Any Dream will do..."

SOL693-2R187894274EFFAKBAP1301R0M1-00.jpgMartian "bone"... (context image) - Sol 69359 visiteE, dato che le sorprese non finiscono (proprio) MAI, ecco la "ciliegina sulla torta", ancora ritrovata dall'ottimo Dr Barca: Spirit sta tranquillamente "arrotando" un curiosissimo oggetto la cui forma e tessitura - totalmente "aliene"... - non hanno proprio nulla che lo possano far assomigliare ad una roccia.
Che cosa sta "schiacciando" Spirit, quindi?!?...
