I'm not sure. There aren't any images on the ESA site. I suspect that this image happened at a point when the orbit of Mars Express took it close to Phobos, so since Deimos has quite a different orbit and is also very small, the orbiter may never get close enough for decent pictures, I suppose.
No images on the ESA site, but that's not due to orbital mechanics. Deimos might seem quite small compared with, say, our moon but it's a naked-eye object with discernible surface features anywhere in Mars Orbit. Unless, of course, Mars is actually in the way. So the cameras on Mars Express will have some very high-resolution images indeed.
Meanwhile, the SF geek admires the familiar image of Phobos and asks: "I wonder if the axis of Stickney Crater passes through the planetesimal's centre of mass..." Call me Crazy Eddie but I think someone's moved my cheese.
We all just pile into the Water Rats. It's not like it's a big place where you can't find people... The Water Rats is down Grays' Inn Road from Kings Cross (mainline) station immediately past the specialist hospital (whose specialties I forget), about 5 mins walk.

Anything on this weekend? On Earth, I mean?

Date: 2004-11-12 07:00 am (UTC)Deimos is actually only about 1/3rd the size of Phobos. It was imaged by the Viking Orbiter in 1977:
and since Mars Express had to be in the right orbit to capture Phobos in detail, I doubt it would give good results for a more distant Deimos.
