I'm starting a map thread. It's hard to know what we will get but I expect a route map will emerge bit by bit. Maps showing the landing location will be easier to make initially.

We have had no news on Tianwen-1 and Zhurong for a while. The rover at least, and probably the orbiter too, are entering a superior conjunction blackout period about now. Their blackout will be longer than NASA's, probably because it's the first time they have dealt with it and will want to be more conservative.
Meanwhile I wanted to show the difference between the existing map and the new Tianwen-1 orbiter image. My map is based on the published map with track and waypoints. The orbiter image shows tracks offset from it, with the offset increasing away from the lander (though the last point is close again). I suspect this is because of a small difference in the definitions of map projections between the projected orbiter image and the route map. (My coordinates are from HiRISE which opens the possibility of another offset, but in all cases I am matching to surface features using HiRISE as a standard). The maximum offset is about 10 m.
