A candidate crash site for Mars 6 is being reported. I'm not anywhere near informed enough to evaluate their work, other than that a lot apparently went into it.

It is an interesting analysis and a promising candidate. For confirmation we would want to see other components of the landing system nearby - especially the parachute. The Mars 3 parachute appears to be visible after all these years, so that of Mars 6 may be as well. If other features are found near here, we would have an excellent candidate. If not this may just be a natural feature that happens to resemble the expected lander appearance.

Took me a second read thru to find the HiRISE image in question
https://hirise.lpl.arizona.edu/PSP_003894_1560

Where in that image it is, however, I have no idea.

I was interested in the article linked to by Hungry4info and having read the English translation (courtesy of Chrome) concluded it gives no information to the candidate location (other than the image). So I set out to find it using https://www.uahirise.org/hiview/. My coordinates for the candidate location: center at pixel 24175x,37145y which is towards to bottom right corner of the image.
Here is a screen shot of the area, from HiView, superimposed with the article's image, for comparison. By the way, the location seems to have the configuration predicted by the impact simulations as shown in the article's videos.

The article does not point to any other items, such as the parachute. I searched the web for information but could not find for sure if the parachute was attached to a back shell (that might have acted as a sort of anchor). If not, as the image appearing in the Mars 6 Wikipedia article seems to show, the parachute could have been blown by the wind a considerable distance. The wind direction seems to be, predominantly, from the lower left to the upper right. I made a shot of an area about 800x800m (about 3200x3200 px) centered on the candidate and there is nothing that catches my untrained eye.

If I find something further I'll post it here. Cheers

Good find. Really not that compelling when you see it in context.

Here is a GIF of the Hiview image of the candidate MARS 6 object and my deconvolution image

Here is a close-in image of the deconvolution ... 6x



thoughts:
* There is only this one really bright object for miles
* Usually for a crater this small we don't see stuff just as big coming back out
* Or it's just another Mars coincidence
* Your mileage may vary

The HiRISE image https://hirise.lpl.arizona.edu/ESP_037703_1560 partially overlaps the area and further extends it eastward.
The proposed location is centered at pixel 7982x,30528y. Illumination seems to be more favorable (as compared with PSP_003894_1560).
Again, I could not locate anything looking like a parachute.
