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:

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.

A recent article about processing Mars 3 signals (in Russian).

Abstract. The paper analyses signals from telephotometers installed on the lander of the Mars-3 space probe, which landed on the surface of Mars for the first time in the world in 1971. The duration of operation of the spacecraft transmitters is estimated, the imaging modes are analyzed, and the level of illumination at the landing site is determined. The geometrical characteristics of the images are substantiated based on the analysis of the received signals. A specialized algorithm is used to reconstruct fragments of panoramas transmitted by the lander and to carry out an overview analysis of these images. The historical value and significance of the results obtained are emphasized.
Keywords: Mars-3, signal analysis, image reconstruction
