Shown here is a mosaic of seven of the sharpest, highest resolution
images taken of Phoebe during Cassini's close flyby of the tiny moon.
The image scales range from 27 to 13 meters (90 to 43 feet) per pixel.
Smaller and smaller craters can be resolved as resolution increases from
left to right. The number of blocks, or bumps on the surface also
increases to the right. The Sun is coming from the right, so the
bright-dark pattern is reversed between blocks and small craters. Grooves
or chains of pits are seen on the left portion of the mosaic, which may
mark fractures or faults induced by large impact events. Many of the
small craters have bright rays, similar to recent craters on the Moon.
There are also bright streaks on steep slopes, perhaps where loose
material slid downhill during the seismic shaking of impact events.
There are also places where especially dark materials are present,
perhaps rich in carbon compounds.
The Cassini-Huygens mission is a cooperative project of NASA, the
European Space Agency and the Italian Space Agency. The Jet Propulsion
Laboratory, a division of the California Institute of Technology in
Pasadena, manages the Cassini-Huygens mission for NASA's Office of Space
Science, Washington, D.C. The Cassini orbiter and its two onboard cameras,
were designed, developed and assembled at JPL. The imaging team is based
at the Space Science Institute, Boulder, Colo.
