Some nice Mars pics from MRO

Awhile back I saw many shots over on the MRO site and downloaded my
favorites for personal viewing. The other day I stumbled across them
again, and thought that perhaps somebody here might enjoy them too
(ordered roughly from most-liked to a little less so):

intersting pics. But the site.. well let me just say that yellow text on
white background is damn near invisible (similar to another bad color combo
- dark blue on black)

#7 looks like a sneaker track in the martian sand :-)
maybe aliens also wear sneakers
Anyway, the pics are fascinating

Zoom in to the upper right quadrant of image "mars4RGB". In the valley near
the light colored ridge looks like rover tracks maybe? ...Or, Marvin the
Martian foot prints?

Wow, that's pretty interesting. Here's a link to the original
location of that file

http://hiroc.lpl.arizona.edu/images/...5_RGBsamp2.jpg

I'm going to contact a friend of mine who works a JPL to see if he
know if that is a common artifact or something else.

Great!

I'd be interested in what you find out!

Thanks!

I think the upper more curving track was left by a boulder that rolled
down the hill. The boulder is at the end of the track.

But I think the other apparently double line may be either an artifact
or a real feature that is just below the resolution of the image,
resulting in an optical illusion (the segmented pattern). I think it is
most likely a line of exposed rock; the pixellation in sharp lines
running up/down and left/right creates the illusion of segments.

Note that there is a third line below and roughly parallel to the
second. It is faintly seen below the second line separated by about the
same distance as the other two. It shows a similar pattern.

Hi Greg, I noticed the second set below the first too. The first
thought I had was perhaps the digital processing is missing data after
so many iterations for each pixel line. The other thought was that if
you look at the second set of lines, it also has a very similar object
at the end of the "track" (i.e. it seems unlikely to me that two
boulders would look the same way, but not impossible; the other
thoughts were two rovers conducting the same search pattern, or the
pixel errors repeating.) In any case, it would be interesting to see
another image of that location. (I didn't hear back yet from that guy
at JPL; perhaps somebody here is familiar with this kind of pixel
error or artifact from MRO or other cameras?)

Regards, Jason H.

I'm not sure we are talking about the same sets of lines. I've
annotated what I see he

http://www.skyhound.com/dl/mars_lines.jpg

Are those the tracks you were talking about? To see the lower curved
track it helps to magnify the image.

I think I see the boulder near the end of the upper dual track, but I
don't see any compelling evidence that it is truly at the end of the
track. I don't see any boulder near the end of the lower dual track.
Also if the upper dual track was created by a rolling boulder like the
first one, it should have been similarly deflected, curving upward like
the first.

Although I am not familiar with the MRO cameras, I did the image
processing for Mike Malin and his Mars Orbiter Camera (on MGS) some
years ago, so I do have some experience interpreting image artifacts.

It's difficult to imagine what sort of image artifact would cause these
dual curving lines. But if I magnify by 400% and compare the top line
to the dual lines, I get the sense that the dual lines are different in
nature, less well defined--almost as if they have a different
resolution. This leads me to suspect some sort of image artifact. If
get the chance I'll look into how the camera works. Maybe there is a
clue there.

Clear skies,
Greg

Yes, I have to agree that those are most-likely boulders after blowing
it up 400X, which you can see at:

Thanks for looking at that.
