Descriere


English: View of a small region of the thin, disrupted, ice crust in the Conamara region of Jupiter's moon Europa showing the interplay of surface color with ice structures. The white and blue colors outline areas that have been blanketed by a fine dust of ice particles ejected at the time of formation of the large (26 kilometer in diameter) crater Pwyll some 1000 kilometers to the south. A few small craters of less than 500 meters or 547 yards in diameter can be seen associated with these regions. These were probably formed, at the same time as the blanketing occurred, by large, intact, blocks of ice thrown up in the impact explosion that formed Pwyll. The unblanketed surface has a reddish brown color that has been painted by mineral contaminants carried and spread by water vapor released from below the crust when it was disrupted. The original color of the icy surface was probably a deep blue color seen in large areas elsewhere on the moon. The colors in this picture have been enhanced for visibility. North is to the top of the picture and the sun illuminates the surface from the right. The image, centered at 9 degrees north latitude and 274 degrees west longitude, covers an area approximately 70 by 30 kilometers (44 by 19 miles), and combines data taken by the Solid State Imaging (CCD) system on NASA's Galileo spacecraft during three of its orbits through the Jovian system. Low resolution color (violet, green, and infrared) data acquired in September 1996, were combined with medium resolution images from December 1996, to produce synthetic color images. These were then combined with a high resolution mosaic of images acquired on February 20th, 1997 at a resolution of 54 meters (59 yards) per picture element and at a range of 5340 kilometers (3320 miles).
Deutsch: Das von der Jupitersonde Galileo aufgenommene Bild des zeigt die dünne zerbrochene Eiskruste der Conamararegion des Jupitermondes Europa. Die blauen und weißen Gebiete sind von einer feinen Eisstaubschicht bedeckt, welche bei der Entstehung des 26km großen Pwyll-Impaktkraters einige 1000 Kilometer weiter südlich ausgeworfen wurden. Einige kleinere Krater von weniger als 500m Durchmesser im Bild sind wahrscheinlich von größeren ausgeworfenen Eisbrocken bei der Entstehung des Pwyll-Impaktkraters verursacht worden. Die unbedeckte Oberfläche hat rotbraune Färbung, welche durch in Wasser und in Dampf gelöste Mineralien verursacht wurde, welche an die Oberfläche quollen, als diese zerbrach. Die ursprüngliche Färbung des Eises wird wohl in weiten Gebieten des Mondes ein tiefes Blau gewesen sein. Die Farben des Bildes wurden zur besseren Sichtbarkeit verstärkt. Norden ist oben auf dem Bild und die Sonne scheint von rechts auf die Oberfläche. Das Bild ist auf 9° nördlicher Breite und 274° westlicher Länge zentriert und zeigt ein Gebiet von 70km mal 30km. Es wurde aus drei einzelnen Bildern während dreier Vorbeiflüge an Europa erstellt um die Farben zu erhalten: Niedrig auflösendes Bilder in den Spektralbereichen Violett, Grün und Infrarot vom September 1996 wurden mit Bildern mittlerer Auflösung vom Dezember 1996 kombiniert um synthetische Farbbilder zu erhalten. Diese wurden dann zum Schluss mit einem hochauflösenden Bildermosaik vom 20. Februar 1997 (Auflösung 54 Meter/Bildpunkt auf einer Länge von 5340km) kombiniert.
