Looking again closely at the Venera 13 camera 1 raw data, I made an small interesting (discovery : the lander has moved slightly between the 2nd and 3rd clear pans. So I did a quick pixel overlap between the 2nd and 5th clear pans to gain higher resolution.
Here it is (at right, compared to a "regular" image). Unfortunately, this is the only segment available with no noise. To build an entire hi-res panoramic picture with no noise, I would need to fill in the gaps of the 2nd pan, with data from 3rd to 5th clear pan, thus useless to make hi-res ! ...And see the prominent hill at the horizon ! Enjoy the two pictures : (i) comparison and (ii) perspective oriented 45° to simulate what you would see if you were on Venus ! |

Enjoy the two pictures : (i) comparison and (ii) perspective oriented 45° to simulate what you would see if you were on Venus ! Venera 13 transmitted data from the planet's surface for 2 hours and 7 minutes, the longest of any lander there. And of all the landers that contained seismometers, only one detected what may have been a very faint and distant quake. So this begs the question: If the lander movement was real, was it due to a surface movement, was it slipping off one of the rocks, perhaps because it was on a small hill or an angled rock - or was it pushed? -------------------- "After having some business dealings with men, I am occasionally chagrined,
and feel as if I had done some wrong, and it is hard to forget the ugly circumstance. I see that such intercourse long continued would make one thoroughly prosaic, hard, and coarse. But the longest intercourse with Nature, though in her rudest moods, does not thus harden and make coarse. A hard, sensible man whom we liken to a rock is indeed much harder than a rock. From hard, coarse, insensible men with whom I have no sympathy, I go to commune with the rocks, whose hearts are comparatively soft." - Henry David Thoreau, November 15, 1853 |
