Tempel1-S-ImpactConfirmation.jpgTempel-1 from Kitt Peak National Obs.59 visiteOriginal caption:"The image was taken through an R band filter and has the smoothed dust light profile removed to enhance the jets. North is up, East to the left, the Sun at PA (Position Angle) 290 and the FOV is 2,5 arcmin (which is now 96.500 km at the comet)".

Mimas-PIA07534.jpgRound? Not really...59 visiteCaption NASA originale:"Saturn's moon Mimas, whose low density suggests that it is primarily composed of ice, has a flattened or oblate shape reminiscent of Saturn's. The moon's equatorial dimension is nearly 10% larger than the polar one due to the satellite's rapid rotation. This view shows principally the leading hemisphere on Mimas. Mimas' largest crater, Herschel (130 Km, or 80 miles wide), is centered roughly on the equator and can be seen here. North on Mimas is toward upper left.
The moon's oblateness is exaggerated by Cassini's viewing angle here -- the Sun-Mimas-spacecraft, or phase, angle was only 5° leaving a sliver of the moon's disk in shadow on the northwest limb.
The image was taken in visible light with the Cassini spacecraft narrow-angle camera on May 20, 2005, at a distance of approx. 916.000 Km (about 569.000 miles) from Mimas. Resolution in the original image was 5 Km (about 3 miles) per pixel".

Enceladus-N00037076.jpgGood-bye Enceladus! (1)59 visiteEncelado è ormai una splendida "falce" nel cielo e questo ci fa capire che la Sonda Cassini ha ormai superato il suo punto di maggior vicinanza a questo mondo di ghiaccio e di neve, i cui caratteri superficiali terranno impegnati Scienziati e Ricercatori per mesi (o forse anni...).
Cassini si allontana rapidamente ed ora si sta proiettando, ancora una volta, verso lo Spazio di Saturno.
Ma ritornerà...
