HRSC images of Phobos now online
The Mars Express High Resolution Stereo Camera (HRSC) flyby images have just been published in the ESA web portal. Access the full article & images plus very cool animations provided by the HRSC team... -- Daniel

Fantastic images, thank you for posting so quickly. One question, though? How was a "north" determined? Seems arbitrary. I know Dr. Who said, "Lots of planets have a North", but a moonlet? Just curious (though I'd love to have those images without the N tag, now that we know where North is). Congratulations to your whole team, you are fantastic.

additional question : could you provide us with the exact (L,l,radius) locations of possible sites #1 and #2, please? (approx.L,l = 5°S-5°N, 230-235°E)

the above coordinates come from here : http://www.rdmag.com/News/Feeds/2010/03/environment-phobos-flyby-images/
Surprising! (new origins?) It seems that locations sites are likely at [13°N;129°E]/Site#1 and [19°N;133°E]/Site#2
hum...?

That's really great : we can clearly see the possible Phobos-Grunt landing sites! (they were shadowed during the previous flyby...) It's told about a resolution at 4.4 meters (!) per pixel for the downloadable image... amazing, we'll prepare further 3D terrains :-)

Very well done, fantastic. This is more like it. The striations are still visible on the leading side of the far side (some larger ones were seen by Viking 1 orbiter & MEX earlier on). Did you get some high phase views of the trailing farside?
Like the small crater with the boulder in it. Looks like asteroids 243 Ida & 433 Eros close up like that.

How soon will qualified image interpretations begin to be posted here, if at all?

What is the speed of the Sat. in Orbit

Good question! It's tough in space to say how fast something's going because everything is relative but at the time of the HRSC images Mars Express was moving nearly 10000 km/h relative to Phobos and around 7000 km/h relative to Mars.
