Phobos appears redish (APOD 14 Apr 2008)

Is the reddish hue possibly due to dust blown off from Mars itself? The white streaks from the large crater are intriguing as well. Could that indicate a thin layer of dust or merely ejecta from the impact or ...?

Phobos is supposed to have a surface of carbonaceous chondrite which is a dark material. The reddish color reminds me of rust.

This appears to be sunrise on Phobos.

Is the red from scattering of the Martian atmosphere?

Does anybody know what the bands of red noise pixels are, on the left edge of the full size image?

It looks like it could be embedded data from some instrument on the HiRISE orbiter, very weird.

HERE is a great (big) .MPG file of the entire surface of Phobos.
