Can it find VIKINGS?
Technically, yes, it's perfectly capable of imaging the Viking landers, at better resolution than MOC has acheived to date.
I imagine that it WILL be done, since the positions are quite accurately known, and it's just a case of point and shoot. It's not a high science priority, but it's the sort of PR shot that's good for publicity, so I anticipate that these images will be acquired within the first mapping year.
