Mars Express will do an extremely close flyby of the martian moon Phobos on December 29.

Late this month, ESA’s Mars Express will make the closest flyby yet of the Red Planet’s largest moon Phobos, skimming past at only 45 km [28 miles] above its surface. The flyby on 29 December will be so close and fast that Mars Express will not be able to take any images, but instead it will yield the most accurate details yet of the moon’s gravitational field and, in turn, provide new details of its internal structure.

    Thats tomorrow! Of course it won’t be able to take pictures! The ESA knows that the Phobosians are even more hostile to paparazzi than Alec Baldwin! Want to lay odds on “Sudden Catastrophic Failure”?
