Did nobody notice this:
Ground Team Stays Busy on 10th Anniversary of NASA Mars Launch Ten year after launch, there is some trouble with a solar array motor and a comm problem probably resulting from this and entering safe mode. Nothing dramatic yet, but something to follow closely. There are other things than MRO and MER Analyst |

I should also add in that if this process can be accomplished, it will be extremely difficult, and thus there isn't a fixed day assigned to make the attempt to photograph MGS, only that the attempt should be made reasonably soon, but not to disturb any critical science/ Phoenix endevours.

Lookheed-Martin designs the slew and they tell you when to start imaging. At least, that's how the Odyssey image by MGS was done. Doesn't sound too hard to me. -------------------- Disclaimer: This post is based on public information only. Any opinions are my own.

Teeny-tiny spacecrafts, great big universe. Ephemeris data for Mars is pretty good, though we require more recent updates prior to sending final commands to make sure our targeting is correct. Spacecraft-to-spacecraft ephemeris is not so good because of the variable atmosphere, dynamics of the Sun-Mars-MGS-MRO system, and other factors. Sure, it can probably be done, but it will be hard, especially when there is a regular science mission ongoing with other timely observations required, and a million little things just waiting to go wrong somewhere in the complex process. If the Odyssey imaging by MGS was easy, then wow. |
