- PSP_001521_2025_RED.jp2 taken on 11 November 2006 (w/30.3 cm/pixel resolution) at 3:20 PM ; - PSP_001719_2025_RED.JP2 taken on 12 december 2006 (w/28.8 cm/pixel resolution) at 3:27 PM. So I decided to pixel overlap the 2 pictures retrieved from the LPL site at their maximum resolution (as "full JPEG 2000" images), knowing that each individual pixel from those 2 images would not cover exactly the same area on Mars. The goal was : 1. to gain some resolution over individual pictures ; 2. to assess the reality of some features as seen from orbit ; 3. to determine is some individual Lander components could be seen ; 4. to see an "average" site free from bad pixel and false features. After a painstaking process, here are the results on the 4 goals : 1. resolution gained : ==> not obvious on overlap image ; 2. reality of some features : ==> real features are seen on overlap image ; 3. Lander components : ==> some individual components discriminated ; 4. "average" site free from bad pixel and false features ==> goal attained. About the lander itself : the shadow seen for its high-gain antenna mast and for its antenna itself is narrow. This implies that the disk-shaped antenna was not facing the sun when the images were taken, meaning that the high-gain antenna is pointing either towards the north or towards the south. The same overlap processings were also applied to the area where the backshell touched down the surface with its parachute ==> An overlap image is seen also. About the landing site itself around Lander 1 with its features, please refer to the explanations given it the previous post : http://www.unmannedspaceflight.com/index.p...ost&p=79379 Enjoy ! |

"Does anyone know if tapes of the EDL footage are available anywhere? I'd love to watch it all over again.)"
I have no idea, I wish/hope it exists. I have stereo reel-to-reel audio audio tape of dual-network TV coverage of the Viking 1 landing. Unlike the continuous NASA-TV-like NASA mission commentary that I recorded during the Surveyor 1 moon landing in 1966, a decade later, the Viking landing coverage is totally dominated by "talking heads" and celebrity commentary with the exception of a bare minute of NASA narration right around landing and for a few seconds or so after. Granted, the talking heads were people like Ray Bradbury and Carl Sagan, as I vaguely recall... But Iwanted the real thing and got only a snippet of it. I recorded dual network coverage, eg CBS and NBC, from 2 TV's onto stereo tape so I have synched sound, and the one snipped of coverage when both networks carried it, comes in the "center channel" while network blather is only out of right or left speakers. (This is what I remember, I haven't played the tape in decades) I now have a quality reel-to-reel recorder and will soon be able to get some of this stuff digitized and transferred to CD-R discs and mp3 files. |
