- 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 ! |

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!!!)
Thanks for that clip, Imipak! Man, time sure does affect memory; I could have sworn that the first image came down in a right-to-left sweep, but it was the other way around. The difference in brightness in the first lines on the left vs. the rest of the pic were thought to be caused by dust disturbed by the landing exhaust settling down again. -------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

Hey...I'll just have to count with the help from you guys on dealing with all the stress I know will be passing through...
ustrax's a martian virgin...that's the reality... Got some lines from Ray Arvidson...: "the team has confirmed the mission’s final landing site on the last week. So…what scenario will we be facing? Quoting Arvidson, Phoenix will find a location dominated by smooth, relatively rock free plains with numerous periglacial polygons where the team expects water ice to be only a few centimeters beneath a cover of loose regolith." I'll try to dig some more on this on Monday... EDITED: Oh...and we have a confirmation... "Peter Smith, Phoenix Principal Investigator, has confirmed his presence at spacEurope on April 14 (only 9 days from now…) for a live Q’n’A with the readers of this blog, so, get yourself prepared, think about the questions you may have about the mission and submit these when the day arrives, I assure you our PI will not disappoint you." -------------------- "Ride, boldly ride," The shade replied, "If you seek for Eldorado!"
