Surveyor Lunar Roving Vehicle, phase I. Volume V - System evaluation Final technical report
http://ntrs.nasa.gov/archive/nasa/casi.ntr..._1966004162.pdf -------------------- "After having some business dealings with men, I am occasionally chagrined,
and feel as if I had done some wrong, and it is hard to forget the ugly circumstance. I see that such intercourse long continued would make one thoroughly prosaic, hard, and coarse. But the longest intercourse with Nature, though in her rudest moods, does not thus harden and make coarse. A hard, sensible man whom we liken to a rock is indeed much harder than a rock. From hard, coarse, insensible men with whom I have no sympathy, I go to commune with the rocks, whose hearts are comparatively soft." - Henry David Thoreau, November 15, 1853 |

Well, I haven't located any actual images from the Explorer 49 cameras on the Web -- but I have confirmed that both Radio Astronomy Explorers carried a pair of facsimile cameras to observe the behavior of the long deployed booms, and I've at least found the ID number for a published NASA report on the performance of Explorer 49's cameras (which had image compression of fully 32 to 1). This paper may be your best bet for finding actual images from it:
___________________________________ 12. On-board image compression for the RAE lunar mission Miller, W. H.; Lynch, T. J. NASA Center for AeroSpace Information (CASI) IEEE Transactions on Aerospace and Electronic Systems, AES-12, May 1976 , 19760501; May 1, 1976 The requirements, design, implementation, and flight performance of an on-board image compression system for the lunar orbiting Radio Astronomy Explorer-2 (RAE-2) spacecraft are described. The image to be compressed is a panoramic camera view of the long radio astronomy antenna booms used for gravity-gradient stabilization of the spacecraft. A compression ratio of 32 to 1 is obtained by a combination of scan line skipping and adaptive run-length coding. The compressed imagery data are convolutionally encoded for error protection. This image compression system occupies about 1000 cu cm and consumes 0.4 W. Accession ID: 76A34178 Document ID: 19760051212 |
