For those who haven't already seen, there is excellent work independently tracking and predicting the trajectory of Tianwen-1 by radio amateurs (using that word only technically, since they are very much pros).
The latest is predicting orbital insertion at 8 seconds before 1200 UTC on Wednesday 10 February, with a 386 km periapsis - burn starts a few minutes before that if you, like me, are planning your peanut consumption carefully this week. Plenty of details to be found at these links (even a GMAT script and Jupyter notebook, and some doppler data, for the astrodynamically inclined). https://destevez.net/tag/tianwen/ Daniel Estévez recent twitter thread with MOI images Scott Tilley recent twitter thread |

This is the new surface image roughly projected for perspective"
And the location in the latest HiRISE image with the surface image field of view approximately mapped. The rover is visible at the upper edge. Phil -------------------- ... because the Solar System ain't gonna map itself.

This is the new surface image roughly projected for perspective Thanks Phil. Appears to me that the stones has changed a lot since the first ones... -------------------- "The Earth is a very small stage in a vast cosmic arena"
