Now in 2020...
Does anyone know if the digital data for Mariner 4 is still missing? Is this page https://nssdc.gsfc.nasa.gov/imgcat/html/mis...er_4_page1.html still the most "official" source for Mariner 4 images? |

Looking higher up the thread there was some good work entering data numbers off the famous hand-colored printout of the first image. But I really don't think there is any hope of recovering original digital data. That was a pre-digital era, and digital was just the way the data got to Earth. Once here it was archived on film, like the air photos people were used to working with (ditto Lunar Orbiter, but there the data tapes were rescued and read by heroic efforts) (also ditto Surveyor images, which have been scanned from film but still not released yet).

Phil:
JPL published a series of volumes on development and the flight of Mariner Mars 1964. These were in the JPL TR-##-#### series. For example, one was: Technical Report No. 32-1023, Surveyor 1 Mission Report, Part 1. Mission Description and Performance This was in 3 volumes, #2 was "Science Results", #3 was "Television Images" (a very large sample). All of these were under the number 32-1023. One of the Mariner 4 volumes had a sub-title something "Picture Element Matrices". The ENTIRE volume, after a brief introduction, was page after page of pixel values for the "Reduced Data Record" (something like that). The numbers were (probably) 0-63 (not 6-bit binary). The volume was something like an inch thick. Find it, scan it, do OCR on it, and you should have the final processed "official" version of the Mariner 4 images. I think It went through image #16, maybe 19 (on or just past the terminator.) Ed Strickland (P.S. Long time no see.) |

Thanks, Ed. I wondered if you were still around! I hope the people who were doing that work or are interested - maybe Ted Stryk? - will follow up on that. I had seen the other volumes published at the time but not that one with the matrices.

Phil I have done an extensive search, including LPL, where the original manuscript of the 3rd volume, the one containing the matrices, is supposed to be, but had no luck. -------------------- |

A lot of fairly uninspiring terrain there by pure chance. you can see why it took Mariner 9 to re-awake mars studies!
