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. -------------------- |

.../... 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. When I was working on Russian planetary data at Brown University in 1984, Russian scientists told me that (i) the Mars 3 "image" is a strip that should be seen vertically and NOT horizontally, (ii) in the 20 seconds of data, NO contrast was transmitted : it was just a kind of "carrier"... Sorry, but as Ted said, NO real imaging data there. The Viking landers were the 1st spacecrafts which succeeded in taking images from the surface of Mars... |

In my talks with a few Russians, they have contradicted each other on that...some they it is the very beginning of a scan, others do not. The other issue is orientation...Our understanding of the orientation of the "horizon" line, or even where the horizon should be, could be way off, because we don't know the orientation of the craft, given the possibility that the lander didn't fully open up or tipped over, etc. -------------------- |
