Japetus-PIA08177.jpgThe darkest moon is there...57 visiteA distant glimpse of Japetus reveals details within the dark terrain of the Cassini Regio, including an impact basin at top that is roughly 400 Km (about 250 miles) wide.
Researchers remain unsure about the mechanism that has darkened the Leading Hemisphere.
This view looks toward the Southern Hemisphere on the leading side of Japetus (1.468 Km, or about 912 miles across). North is up.
The image was taken in visible light with the Cassini spacecraft narrow-angle camera on April 4, 2006, at a distance of approx. 1,4 MKM (such as about 900.000 miles) from Japetus.
The image scale is roughly 9 Km (about 6 miles) per pixel.

OPP-SOL833-1N202134591EFF71GBP0705L0M1.jpgThe magnificent "Desolation" of Meridiani Planum (3) - Sol 83357 visiteCerchiatura Fucsia: uno "sbuffo" nel cielo di Marte. Photoartifact, micro-nuvola o qualcosa d'altro? La nostra esperienza ci spinge ad optare per l'ipotesi del photoartifact, anche se non ne abbiamo la certezza.
Tuttavia, anche qualora si trattasse di qualcosa di diverso dal semplice difetto del frame, la sua non buona risoluzione ci impedisce di poter dire qualcosa di definitivo.
Complimenti in ogni caso al sempre ottimo occhio del Dr Barca!

SOL809-PIA08529.jpgSpirit like Opportunity: a Martian "Iron Meteorite" is found... (2) - Sol 80957 visiteCaption originale:"Rocks in the vicinity of Spirit's Winter Station are being assigned informal names honoring Antarctic research stations.
Zhong Shan is an Antarctic base established by China in 1989.
Allan Hills is a site where meteorites are frequently collected because they are relatively easy to see as dark rocks on the bright Antarctic ice. The most famous Allan Hills meteorite from Antarctica actually came from Mars and landed on Earth. If the Zhong Chang and Allan Hills rocks seen by Spirit do turn out to be iron-rich meteorites, they may have originated from an asteroid and landed on Mars.
This view is an approximately true-color rendering that combines images taken through the panoramic camera's 753-, 535- and 432-nanometer filters".

OPP-SOL825-Alamogordo_Creek-B849R1-1.jpgAlamogordo Creek - false colors (1) - Sol 82557 visiteCaption NASA originale:"On its 825th Martian day (May 20, 2006), NASA's MER Opportunity stopped for the weekend to place its instrument arm onto the soil target pictured here, dubbed Alamogordo Creek.
Two views from the PanCam, acquired at about noon Local Solar Time, are at the frames 1 and 2.
Frame 3 is a close-up view from the Microscopic Imager (MI).
This frame is a false-color view that emphasizes differences among materials in rocks and soil. It combines images taken through the PanCam's 753-, 535- and 432-nanometer filters".
