Venera Images, VENERA 13 fully calibrated image Options

[vikingmars]

Here is the Venera 13 fully calibrated image, produced from raw imaging 3-filters data (note the 3 horizons at left well discernible). It was published inside "L'Astronomie Magazine" of Societe Astronomique de France.
Enjoy !

Very different type of terrain. Mainly rocky, no sand or silica dust. No water erosion signs. Interesting.

While these new presentations are aesthetically wonderful, the old, unnatural-looking presentations of Venera imagery allowed this level of observation, so they are not new to us. The four sites are quite different, with boulders atop/embedded in soil at two sites and large, plate sheets of rock at the other two. It is certainly the case that water erosion could not have acted on any portion of Venus's surface since the last major resurfacing event (if ever) -- if there are any ancient surfaces that show past water influence of any kind, we will have to hunt them down very carefully. Such formations may not exist at all.

There is sand/pebble soil visible in Venera 9 and Venera 13 surface views. Fine dust may be rare. It seems likely that chemical production of dust is not a major phenomenon, and mechanical processes that produce dust seem to be rare also. Because the surface temperature is very constant, there are only light winds, so dust will not beget new dust much.

I have always thought the Venera 9 site looks like a Viking landing site.
