It looks as if Mike and Phil's efforts have paid off biggrin.gif

Deimos!
MGS MOC Release No. MOC2-1551, 11 August 2006

EDIT: Sorry, Phil, I didn't read all the way to the bottom of the release.

Glad to see MOC has now imaged all the members of the "Mars system." smile.gif

This is the map I sent to Mike to help identify which craters were which in the image.

Mike can correct me if I'm wrong but I believe the Mars Observer Camera (i.e., MOC1) would have returned even more spectacular views of both martian moons, primarily due to the nature of the descent from elliptical capture orbit to final mapping orbit.

Off topic: Ted, is your signature purposely coded the way it appears?

Great to see the results of a conversation that started here turning into real pictures!

These obs would probably have been taken anyway, but to think that this place might have played a small role is fantastic smile.gif

Great planning by the MOC team......now...any plans to try and image MRO smile.gif

I should have added this before - if you look closely at the MSSS release and my image a few posts up, you will see that they are mirror images of each other. The raw MOC image is flipped, and in my image I have corrected this so the moon looks like it would to you if you were there. I thought MSSS would correct for that in the release but they didn't. This serves as a warning to anyone browsing the MOC image gallery, that some images are flipped. Usually it makes no difference to you until you try comparing it with maps or other images.

I didn't work on this release, and I think more effort could have been spent on it, but when you're banging these things out once a day, there really isn't much time to spend on any given one.

Images in the gallery are raw out of the camera. I tried to make it as clear as I could in the ancillary data what the flipping status is. Obviously the map-projected versions are north-up east-right as one would expect.

Actually, I doubt this image would have been taken otherwise; it's not really that great or useful an image considering the range (but it probably would have been silly to have not tried it at least once.)

I haven't heard any specific plans to image MRO but I wouldn't be surprised.

This might have been true for Phobos, where there was some effort planned to make the "1-day drift orbit" period be an integer multiple of the period of Phobos and so produce a close approach on each orbit. I don't think the Deimos geometry would have been much improved, though.

Don't get me wrong, Mike, I was very pleased to see the release. I just want people to know what they are looking at.

I must admit, when we first discussed it, I hoped the view would reveal more of the trailing side. The limb in this view is on a north-south trending ridge line. Behind it, to the east, is a broad flat or concave region, and then another ridge beyond that. I hoped for a view of the far ridge, but viewing from so close to Mars, we just don't get far enough to the east in Deimos sub-spacecraft coordinates to see past the first ridge. Still, as I said before, this is the only image which puts a limb in this region of Deimos, and that's useful input to shape models, which are still very poor in this part of Deimos.
