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!

A montage of 17 of the 18 asteroids and comets that have been photographed up close as of August 2014, when Rosetta arrived at comet Churyumov-Gerasimenko. This version is in color and shows the bodies at their correct relative (though not absolute) albedo or brightness. Not included are Vesta or Ceres, both of which are many times larger than Lutetia.

Locating the Philae landing site

Locating the Philae landing site

This series of images indicates the location of the first touchdown of the Philae lander on comet Churyumov-Gerasimenko. A NavCam image, on the left, provides global context. The next two images, from the OSIRIS science camera, give regional context. The final two images, from the ROLIS descent camera, localize the landing site. However, indications are that the spacecraft bounced, so the final landing site is likely in a different location.

Rosetta's NavCam view of comet Churyumov-Gerasimenko on August 31, 2014 from a distance of 61 kilometers. The four-image mosaic has been resampled to a resolution of 5 meters per pixel; the photo is 6 kilometers square.
