Viking 1 & 2 landers from HiRISE, Landers definitively spotted Options

[climber]

Oui, Climber !
Merci et ça m'a fait très plaisir (et une agréable surprise) de vous rencontrer à TSE...
La toute "première" des images a eu lieu en fait voici 15 jours à l'Adler Planetarium de Chicago devant des centaines d'auditeurs. Elles étaient présentées officiellement par la Nasa/Hq avec Buzz Aldrin, Gene Cernan et Jim Lovell... D'autres présentations auront lieu aux US prochainement, mais je n'en ai pas le calendrier... Je suis "off" pour Mars tellement le boulot est énorme... Ce travail a été entamé dès 1984 à Brown University pour le repérage des images. Les premiers tests d'assemblage ont eu lieu en 1998, les validations des corrections chromatiques en 2001... Puis j'ai eu ma "parenthèse" MER pour aider à monter l'Outreach en prévision du succès que vous connaissez.
Bon, il faut que je reparte sur la Lune...
Amitiés,
Olivier.

Thanks again Olivier,
I'm sure our friends "on the other side of the pond" will be gratefull if you post a calandar of the show if (and when) you'll know it.
Toulouse was fantastic but meeting Aldrin,Lovell and Cernan, would have been...I even don't dream of this.
Amitiés.

Found these informative sketches on:

http://history.nasa.gov/SP-425/contents.htm

(scroll to bottom and see Panoramic Sketches)

they give the all important (to me at least) "North South East West" markers on the Viking Pans so that you can compare them to the HIRISE

Is it possible that UV radiation or weathering is breaking down some material present on the Viking landers?

Viking 1 as seen by HiRISE has a light trail eminating vertically from the lander:

Viking 2 from HiRISE also has a similar streak stretching to the lander's left:

The light streaks may simply be due to deposits of lighter material built up by the wind as it interacts with the landers. However the large boulder 'Big Joe', seen just to Viking 1's upper right, doesn't sport such a light streak.

Could the light material be something stripped off the landers due to their prolonged exposure on the Martian surface?

Perhaps the interaction of the rockets during landing - not sure how much or for how long it would make an impact on the ground though.

I see the streaks you mean, but I don't think they are very significant. Almost anywhere you put a lander on these complex surfaces, some sort of marking might appear to be associated with the spacecraft. Pick a random nearby spot and see if it also has a streak.
