On my website sometime back, I added a page on the image fragment sent back by the Mars-3 Lander. I released serveral versions, including the best quality processing using othodox techniques I would use on other images plus colorization here:
http://pages.preferred.com/%7Etedstryk/fragmentc.jpg However, I released another image, which I called a "What if" image. This image can be seen here http://pages.preferred.com/%7Etedstryk/m3s5b.jpg It was produced via extreme processing of the original data to make a Mars-like scene, but I made it clear on my website it was only a speculative image. I strongly doubt if the raw data even shows Mars at all - it could be all noise. But since this mode of processing looked strangely Viking-like, I figured I would put it on the web. I was warned by several, who said that while fun, some kooks might take it seriously. My response was that I really don't care what kooks think. Then I noticed this web page: http://en.wikipedia.org/wiki/Mars_2 They used the overprocessed image. I feel like it is being presented as a true photograph. This is of concern. -------------------- |

On his excellent site on Soviet Space Cameras ( http://www.mentallandscape.com/V_Cameras.htm#Luna9 ) Don Mitchell shows a pen plotter display of the signal from the Mars 3 lander ( http://www.mentallandscape.com/V_Mars3Signal.jpg ), I suspect this plot is the source of the circulating "Mars 3 image", the true plot (and tape?) must be somewhere hiding in some Russian archive if it still exists.
As explained on above site, the plotter was drawing with horizontal strokes, however the camera was scanning with vertical lines, so the image should be rotated by 90 degrees. As also noted by Perminov, the "picture" was featureless, just a grey background. I seem to remember reading somewhere that there was even doubt whether or not this was the actual video signal, the transmitter was working but the camera itself was not (yet?) online. After only 14.5 seconds the signal from both camera's was lost. We don't know what happened to the Mars 3 lander, we DO know that the Mars 3 orbiter, who relayed the signal, had serious trouble burning into mars orbit, ending up in a completely wrong orbit (period of 12 days instead of 25 hours) and losing 3 axis stabilization for about one hour, this doesn't sound like a very favorable situation for a data relay and might explain why the signal was lost. The lander was pre-programmed to transmit for 25 minutes, where after it would go into hibernation waiting for a signal from the orbiter on its next orbit, however due to its erroneous orbit the orbiter did not pass the landing site again until the lander battery's were long dead, so they never got a second chance to contact the lander. |
