Sun SD from Mars: 10.5'
An interesting observation is available. Earth to Earth's Moon lunar! Similar to a Jovian satellite observation. But its a "lunar" from a strange perspective, as the two objects rotate about the barycenter. We should be able to distinguish the two objects and their apparent distance.
Phobos, with an orbital period of 8 hours, and Demos, with an orbital period of 30 hours, could provide excellent longitude resolution. Even more so if the Phobos/Demos distance is utilized. 360 degrees in 8 hours is 45 degrees per hour (45'/ minute), which compares to our more pedestrian 0.5°/hour.
But if its a one way trip, do you go?

OK, I am game.... when do we go?
