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 |

Funny how time flies (When you're having fun)
On Friday 21 July at around 05:04:47 UTC, Mars Express (MEX) will make a close flyby of Phobos at a distance to the surface of just 48.4 km, according to the latest MEX SPICE Kernel Dataset (SKD), via WebGeocalc (WGC). My clumsy freehand overlay of a WGC-generated Nadir Ground-track plot on a colour-coded topographic map of Phobos seems to be in good agreement with the corresponding Sub-point radius vs. Time plot. The blue arrow shows the flight direction, the two concentric circles mark the point of closest approach to the surface, the small dots on the plot are one second apart, and the length of the plot between start at 05:03:42.465 and end at around 05:05:54.924 UTC is the time period when the distance between MEX and the centre of Phobos is less than 200 km. |
