Thank you very much Huguet for those nice processings of yours You are welcome. It is visible the action of the dust in the white jet fuel surrounding the lander. On the tracks we can see little action, most the tracks are still the same 1 year latter. I was missing new Zhurong pictures. Here follows a processing of the released one showed on Phil link. The dust appears to be acting more at the transmitter mast. -------------------- "The Earth is a very small stage in a vast cosmic arena"

This open-access paper:
https://mdpi-res.com/d_attachment/remotesen...14-00709-v2.pdf describes the descent imaging used by the TW-1 lander for hazard avoidance and localization. Phil -------------------- ... because the Solar System ain't gonna map itself.

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 -------------------- |

An update tweeted by Andrew Jones:
https://twitter.com/AJ_FI/status/1522461426010443776 and the link it contains: https://mp.weixin.qq.com/s/upO6NTh-AZ7oNLjv0BmNdw Two orbiter images and a new view of a crater with rocks on its rim. Phil -------------------- ... because the Solar System ain't gonna map itself.

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.

The early rock might have been weathered on the surface for a hundred million years. The later rock looks like it was recently excavated by a small impact, so much less weathered. But we need a better image of the new rock!

Sun Zezhou, chief designer of Tianwen-1, delivered a presentation about China's Mars exploration goals. In it, it was mentioned that Tianwen-1 will test aerobraking at Mars to lower its orbit to gain some experience for this ahead of the future Tianwen-3 mission. Presumably this means the orbital period and thus the regularity with which it can act as a relay for Zhurong will change, but I haven't seen anything about that so far.

This tweet from Andrew Jones shows a surface image from the same original Chinese source as those orbiter views:
https://twitter.com/AJ_FI/status/1542045651101442049 Here is the image in a rough perspective view: I believe it was taken at the last point on this map, approx. sol 300 of the mission: A Tianwen-1 orbiter image of the rover at that location was also released earlier - showing tracks and the rover (also in post #74 above): https://news.sina.com.cn/c/2022-03-24/doc-i...ii0221404.shtml (The orbiter image is one of those on that site) The map I posted here does not show the more recent drives and the current location at the hibernation point. That will follow. Phil -------------------- ... because the Solar System ain't gonna map itself.

Hello Phil, Here follows the original link: http://www.chinanews.com.cn/gn/2022/06-29/9791303.shtml I Attached the original image and a processed one. I believe these lines at the dune are new for me. It would be nice if Zhurong get some closes of then, to understand how they are forming. Apears to be related with these black spots, mabe some light material pushed by wind, creating random patterns. -------------------- "The Earth is a very small stage in a vast cosmic arena"

Interesting! Rather a miniature version of the Walking Rocks at Death Valley. Possibly wind-moved rocks among saltating sand grains?
Maybe we can get Ralph Lorenz on the case? #ralphlorenz --Bill -------------------- |
