The Two Faces of Phoebe

Posted 2014/02/13 10:03 CST | 7 comments

Cassini flew past Phoebe on June 11, 2004, on its way to entering Saturn orbit. The flyby was almost perfect but overexposure of some images have prevented color mosaics from being produced. Even though Phoebe's body is gray and dull in color, the absence of color images always provoked me. By using VIMS data, I have now produced color mosaics.

Images from the long-awaited Dawn Vesta data set

A few days ago, the Dawn mission finally published their archival data. During the year of delay I often looked with anticipation to the Planetary Data System to check whether or not images were there, and I am delighted that they are finally available. Was the wait worth it? Definitely!

Color global view of Ceres: Urvara and Yalode basins

Color global view of Ceres: Urvara and Yalode basins

Posted 2015/10/22 | 0 comments

This approximately true-color image was taken at 15:27 on May 7, 2015, as Dawn was surveying Ceres in its "Rotation Characterization 3" orbit 13,583 kilometers above the surface. At the terminator, near the top, is Urvara, a large crater with radiating troughs. Closer to the center of the disk is the large Yalode basin, with its flat floor and faint inner ring. Farther down the terminator is the large Mondamin crater. Haulani crater makes a bright splash near the lower right edge of the disk. The cone-shaped Ahuna mons is near center.

Ceres, approximately as a human would see it. The photos were taken during Dawn's "Rotation Characterization 3," on May 4, 2015. Occator crater, at center, contains Ceres' enigmatic bright spots.

Four color views of Ceres

Dawn captured the images for these global views of Ceres on May 4, 2015 through red, green, and blue filters. All four pictures are made from the same data, processed in different ways. On top left, it is processed to simulate what a human might see. At top right, color saturation has been increased, revealing a relatively blue inner splash and relatively red outer splash around the crater Occator and other, smaller craters. At lower left, the contrast has been increased, emphasizing relatively brighter and darker regions. At lower right, both contrast and saturation have been increased.
