Another close-up map: this is the rock analyzed by VNIS on day 3:

And look! One rock has a name, Qi Yuan, translated as 'unexpected encounter'. The first name I've seen for any feature along the traverse. This comes from here:

https://els2020.arc.nasa.gov/abstracts (PDF file)

- the abstracts for the upcoming European Lunar Symposium, which will be held virtually next month. On Page 52 of the PDF file is an abstract about this rock with the name included. A full paper is due out soon but not yet available.

I have updated the route map based on a map in the latest drive diary:

https://mp.weixin.qq.com/s/n7ic77uIA-QtniYSRD6gcg

(thanks to Andrew Jones for pointing it out to me).

The 15th night location has been moved to a point where the daily distance figures make sense.

This map updates us to the end of lunar day 17. Using images from the latest drive diary tweeted by Andrew Jones I have been able to map the path reasonably well for day 17 (recent days have been based mostly on Chinese mapping). The exact locations of the last 2 points are a bit uncertain still.

I don't know how useful it can be, but this paper (in Chinese) includes some details of the route of the first and second lunar day:

Thanks, Paolo. This is interesting but doesn't add anything to the early route map which is well documented.

No move during day 18, but I believe we will be back in action for day 19. My map is not changed except for text updates, including the rock name mentioned earlier.

I have been enjoying seeing my map turn up on various Chinese forums and outlets, sometimes with little additions. It's fun to see it diffuse out into the world like that.

A tentative update to the end of the 19th day. No information about the actual path, I am just guessing from descriptions of what was done. An image showing tracks doesn't include anything from day 19, it was taken close to the previous night stop. Possibly it was taken at the mid-day stopping place as it has roughly mid-day lighting, but only more distant tracks are visible.

Another tentative update for the end of day 20. I hope to know more after the drive diary is published some time during the 20th lunar night.

A new drive diary was published here:

https://www.bilibili.com/read/cv6997981

It gives me details for a corrected map:

Only the last drive is guessed here. I think the map published in that article is for the end of the mid-day siesta (it's dated July 23), not the end of the day.

Hey Phil, could you please upload the map as 2 separate images every now and then so I can overlay them into Google Earth?

OK! Send me a reminder when you need it if I forget. These are larger files as well.

This is a bit of an experiment. I am plotting reprojected panoramas onto the base image, using only panoramas with morning to noon lighting (with one exception which I won't go into here). I'm working on the next section now. This version of the map has more information about where VNIS was used, the site numbers etc.
