SOL045-PIA05553.gifMartian Eclipse: Phobos (GIF Movie) - Sol 4555 visiteCaption NASA:"This animation shows the transit of Mars' moon Phobos across the Sun. It is made up of images taken by the Mars Exploration Rover Opportunity on the morning of the 45th Martian Day, or Sol, of its mission.
This observation will help refine our knowledge of the orbit and position of Phobos. Other spacecraft may be able to take better images of Phobos using this new information. This event is similar to solar eclipses seen on Earth in which our Moon passes in front of the Sun.
The images were taken by the Rover's Panoramic Camera".

SOL633-HillaryOutcrop-AW.jpgHillary Outcrop (natural colors - elab. Aviation Week)55 visiteDa "NASA - Picture of the Day" del 13 Marzo 2007:"The Spirit rover attacked Mars again in 2005 September. What might look, above, like a military attack, though, was once again just a scientific one - Spirit was instructed to closely inspect some interesting rocks near the summit of Husband Hill. Spirit's Panoramic Camera captured the Rover's Instrument Deployment Device above as moved to get a closer look at an outcrop of rocks named Hillary. The Spirit rover, and its twin rover Opportunity, have now been exploring the red planet for over three years. Both Spirit and Opportunity have found evidence that parts of Mars were once wet".MareKromium

Un vento freddo avvolge le nostre perdute vite
E ci culliamo nella sua spirale d’ignoto
Nell’oblio perduti,
Dimenticati
In una Ninna-Nanna di Morte..."

Enceladus.jpgEnceladus, the "E-Ring Creator"...55 visiteCaption NASA:"The active moon Enceladus appears to be making Saturn's E-Ring. An amazing picture showing the moon at work was taken late last year (AD 2006) by the Saturn-orbiting Cassini spacecraft and is shown above. Enceladus is the bright point near the center, right near the center of Saturn's E-Ring. Streams of ice and water vapor can be seen pouring off Enceladus into the E-Ring.
The above bright image of the normally faint E-Ring was made possible by aligning Cassini so that Saturn blocked the Sun. From that perspective, small ring particles reflect incoming sunlight more efficiently. Cassini has now been orbiting Saturn for almost three years, and is scheduled to swoop by the unexpectedly cryovolcanic Enceladus at least several more times".MareKromium

The_Rings-PIA08905.jpgClumps in the F-Ring55 visiteCaption NASA:"The brilliant core of the F-Ring displays a breakaway clump of material, possibly related to the other objects the Cassini spacecraft has witnessed in this dynamic Ring in the past few years of observations.
This view looks toward the unlit side of the Rings from about 58° above the Ring-Plane.
The image was taken in visible light with the Cassini spacecraft narrow-angle camera on Feb. 10, 2007 at a distance of approx. 1,7 MKM (1,1 MMs) from Saturn.
Image scale is roughly 10 Km (about 6 miles) per pixel".MareKromium

Saturn-PIA08366.jpgSaturn and Rhea55 visiteCaption NASA:"A serene orb of ice is set against the gentle pastel clouds of giant Saturn. Rhea transits the face of the gas giant, whose darkened Rings and their planet-hugging shadows appear near upper right.
Rhea is the second largest of Saturn's moons.
This view looks toward the unilluminated side of the Rings from about 3° above the Ring-Plane.
Images taken using red, green and blue spectral filters were combined to create this natural color view. The view was acquired with the wide-angle camera on Feb. 4, 2007. Cassini acquired the view at a distance of approx. 1,2 MKM (about 700.000 miles) from Saturn and approx. 679.000 Km (about 422.000 miles) from Rhea.
Image scale is roughly 68 Km (about 42 miles) per pixel on Saturn and about 40 Km (about 25 miles) per pixel on Rhea".
