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!

3D animation of comet Hartley 2's nucleus

Use red-blue glasses to see the 3D effect. To compose this animation of the nucleus of comet Hartley 2, Daniel Macháček used Sqirlz Morph to morph among the five images of the nucleus that were released by the Deep Impact team on the day of the flyby, November 4, 2010, in a process explained here. Then Luca Cassioli took sequential frames from the morphed animation and used them as left and right images in this animated GIF.

Viking 1 observes a dust storm and Phobos' shadow

Viking 1 observes a dust storm and Phobos' shadow

Posted 2015/05/29 | 0 comments

On September 28, 1977, Viking Orbiter 1 observed a dust storm over the site where it had dropped its lander, a little more than a year previously. As Viking 1 orbiter watched, the shadow of Mars' inner moon Phobos passed over the cloud tops. The sequence of images has been artificially colorized and is displayed at a speed ten times that of real time. (Viking images f467a31–f467a69)

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.
