These images, taken by the High Resolution Stereo Camera (HRSC) on board ESA’s Mars Express spacecraft, are Europe’s highest-resolution pictures so far of the Martian moon Phobos. http://www.esa.int/SPECIALS/Mars_Express/SEM21TVJD1E_0.html |

Using spice kernels (for the spacecraft, Mars and Phobos) I tried to simulate the Mars Express Phobos flybies.
Underneath the images of how Phobos would approximately look like at closest approach. The field of view in these images is 30 degrees (I don't know what field of view Mars Express has). 17 july 2008 (273 km)
23 july 2008 (97 km)
28 july 2008 (361)
I wonder how accurate Celestia will be
