Space Forum / Shuttle / May 2008Phoenix - what's the bright 'spike' on the horizon?

Imagery fault? > http://www.nasa.gov/images/content/230000main_SS000EFF896228773_10CA8R8M1.jpg > Right of centre. Imagery fault? Could be the backshell or the parachute, or maybe more lately just a data error/dropout. These are after all unprocessed raw images. > http://www.nasa.gov/images/content/230000main_SS000EFF896228773_10CA8R8M1.jpg > Right of centre. Imagery fault? After looking a little more closely I'm less inclined to believe that is a data error, I'd have to know more about how that particular camera scans to be more certain. If it scans horizontally (either left to right or right to left) then I think an downlink data error being the cause is unlikely. If it scans vertically (down to up or up to down) then it might be a downlink data dropout (incidentally, I think the cameras on the Viking lander cameras did scan vertically, of course that likely says nothing much about how these cameras work). If isn't not a data error then the backshell is a possibility, maybe if the backshell went in edge on into the ground it might give you an image feature like that. Hard to see how the parachute would stick that far off of the ground. Higher resolution color images should be able to include or exclude the backshell being the cause of that image feature (assuming that it is not a downlink data issue). > http://www.nasa.gov/images/content/230000main_SS000EFF896228773_10CA8R8M1.jpg > Right of centre. Imagery fault? Unfortunatly, these are ,jpg images and thus may have compression artifacts. The space alien that is clearly visible is composed of 2 vertical sticks. The top one is a very clearly deliniated set of a 5 pixel high, 1 pixel wide line. The ajoining pixels show seem to be the normal picture. IT is as if someone came in and set those pixels to white after compression. However, below it, are "fuzzy" pixels, about 7 pixels high, and the "pollution" covers about 4 pixels wide, progressively lighter towards the middle. Those are probably part of the original picture and the fuzzyness is due to the lens and image compression. Would the images be compressed to .JPG by the mars ship before transmission, or would they be transmitted as raw images and compressed on earth ? >> http://www.nasa.gov/images/content/230000main_SS000EFF896228773_10CA8R8M1.jpg >> Right of centre.

Images were compressed to "get them for you as soon as possible" in the words of Peter Smith, so it could be compression artificats. Somone at JPL actually suggested it was a polar bear! ;-) But I think it was simply missed pixels. :-) Its obviously white duct tape, we all knew the universe was held together with it.

I understood these were engineering images and the idea was to get them down as fast as possible so my bet is that they are compressed at source. Not that I can see them but it seems logical to me.

Now *that* is a site that I bet they'll be crying about having no rover to investigate, seeing as how it clearly had to hit deep enough to strike ice!
