On Christmas Eve we posted a new image of a small portion of Phobos taken by Mars Express only a few days before, on 22 December, and gave you the challenge of working out where on Phobos you thought it was located.
As correctly commented by JSch, the crater in the bottom left corner is indeed Wendell crater!
Here’s part of the image again, rotated and with coordinates overlaid:
Thanks to our DLR colleagues Marita Waehlisch and Juergen Oberst for confirming the location!
And congratulations to JSch for the quick and correct call!
