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 |

Very cool indeed! The website linked to by Andrew Jones here:
https://twitter.com/AJ_FI/status/1477077043435163650 (same one Hungry4info linked to) also has a surface image from Zhurong, and says the rover has driven 1400 m in 225 days (I assume that means sols). Phil -------------------- ... because the Solar System ain't gonna map itself.
