- 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 ! |

I'll be watching NASA TV from home, very very nervously, and trying not to give in to urges to cross my fingers. I don't ever resist the urge to cross my fingers. I cross my fingers and my toes, and if I can think of anything else to cross, I cross them, too... I'll be watching NASA TV on my home cable system, as well. I am always grateful that I live in a civilized city where I get NASA TV on my cable system. Monday, 26 May is a US national holiday (Memorial Day), so we Yanks are all set. (I'm sure that I'll need that day to recover from Sunday's landing!!!) My schedule is entirely up in the air at this point. I work in a call center for that selfsame cable company that provides me with my NASA TV. (I troubleshoot problems with internet connections and digital phone systems.) We're open every day of the year, and we have bids for working on holidays. I *might* get the holiday off, but more likely I'll have to work the holiday. If I do have to work, I'll get paid double time and a half for working it, though. Problem is, I don't right yet know what my basic schedule is going to be by the end of May. The call center regularly has what they call mini-bids for shifts, when they want to re-tool assets to match demand patterns. But they've had enough changes in the demand patterns that they need to run a once-every-few-years full shift bid, in which every single person has to bid for a new shift. Since I'm about 65th in seniority out of about 120 people in my job, I obviously don't get my first choice... and the new shifts will be announced this coming Monday, to take effect May 4th. So I truly have no clue what shift I will be working on May 25th, or whether I will even have Sundays off. But, in addition to having NASA TV on my cable system, I also have a digital video recorder cable box... *grin*... -the other Doug -------------------- “The trouble ain't that there is too many fools, but that the lightning ain't distributed right.” -Mark Twain
