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

A different story on Mars 2 and Mars 3.
Where did they land and why were those places chosen? I was just plotting the locations on maps of image coverage from previous missions. Mars 2 crashed in Hellas, in the area imaged by Mariner 7. Mars 3 landed right on the southwest corner of Mariner 4 image 13, south of Newton crater. This suggests its target was actually inside the imaged area. The target latitude would be defined by EDL design and the seasons on Mars, and is about 45 south for both missions (incidentally, Wackypedia is waaay off with Mars 2... where did that come from?). It makes a lot of sense for the two mission targets to be in the only areas imaged at that time at that latitude. The site's geological context would be known. And Mariner 7 images seemed to show Hellas was a very smooth plain (actually it was looking at clouds inside the basin), so it would be safe. So all that looks like it might make sense. But then this can potentially be used to resolve the discrepancy in longitudes between NSSDC and Astronautix.com site locations. Astronautix longitudes are ten degrees larger than NSSDC longitudes. But the Mars 3 site wouldn't be in the image area if the larger longitude value is used. EDIT - next day - oops, I'm maligning Astronautix, the incorrect location actually came from http://history.nasa.gov/SP-4212/ch9.html (The NASA history volume on Viking). (Possibly the website used that value earlier and has edited it recently) Any thoughts? Phil -------------------- ... because the Solar System ain't gonna map itself.
