HiRISE and Mars Polar Lander Options

[Guest_Sunspot_*]

Looking at the images of the Spirit/Opportunity landing site, it seems many of the features such as tracks and rocket blast markings have faded considerably often to the point of being invisible in the nearly three years since landing.

This had me thinking about the MGS images taken in the hope of finding MPL. Initially it was reported that MGS had spotted the lander, one image had a white spot/streak interpreted as the parachute and a dark patch with a spot in the centre not too far off, taken to be the blast zone of the rockets with the lander in the centre.

However another image taken 5 years later seemed to discount this theory - the features had faded or changed significantly. BUT, seeing how much the rover sites have changed in an even shorter time, wouldn't the same happen to the MPL site in 5 years - perhaps to an even greater degree with the more extreme seasonal changes at that location. Also, the latest HiRISE images show just how difficult it has been to spot the landers on the surface with MGS, the Viking sites in particular.

I hope HiRISE takes another look at this spot.

I've tidied this thread up a little - MIP, please be more careful before jumping to a conclusion so contrary to the collective wisdom, and then stating quite so forcefully.

The killer point is that if stereo imagery describes the feature as a depression, then the label is irrelevant - illumination is from the lower right. As another post ( which made no sense during clear up, so was culled ) - you must be carefull assuming that MRO is heading south, and the East is to the right. This could be an ascending observation where the geometry would be inverted.
