Mars Express image with two perfectly straight lines

While looking at a hi-res Mars Express image of the Galle Crater I found two perfectly straight lines in it, which I believe is too unusual to be natural occuring, both of them traverse across mountains and craters without changing course, almost like some of the straight NASCA lines on Earth. Furher more the two lines seem to be tilted at the same angle. The first line is about 60 km (37 miles) long, the second is about 70 km (43 miles) long, see the images below:

It looks like an artifact on the lens or on the film, not on the actual landscape. That is my uninformed opinion, for what it is worth.

In agreement with Karl here, it looks to me like the lines are where they pieved together 2 pictures to make one large one.

The lines are dark and smudged this usually an "effect" from lens. None of the textures from the actual land match the lines even according to the shadow directions etc.

this is what happens when you go looking for something specific instead of just examining photos. build up expectations and you'll see what you want to see when its really something terribly mundane.

Simply the effects of putting smaller pictures together to form a larger one.
