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 |

Nice images, Huguet. I wonder why the ground along the vented fuel shows as a white color. My initial view of it was in black.and white, so I assumed it was a lighter tone of the Martian ochre. The white surprises me.
And I be interested in seeing the dust accumulation on the solar panels. --Bill -------------------- |
