Mars Opportunity anomalies

[deuem]

To all,  I took the jpeg in and then also the png file. The png file has no artifacts like the jpeg does. So ArMap is correct on that. As far as the thread goes many readers may not be able to open a png file at home. Tainted, that is up to you. The jpeg file was 524kb and the png 633kb, so size is not an issue. I then converted the png to bitmap 4mb,  tiff @ 4mb and gif @ 677kb and there are other options.  So it looks to me, it depends on what you want to do with the photo. Look at it or study it.

I took that photo into CAD and it hits 4, 8x8 pixel blocks.

Just before posting this, I also took the png file and converted it to jpg just to see what would happen. It looks the same as the png file.  Huh? Any clues on what happened? Tainted, can you try this. It only added 1kb to the jpg file.  I have a converter that will convert just about anything to anything. 3 clicks.

I am such a Mars rookie!!  Zorgon, thanks for the pics....

Here is some sky artifacts SOL 2552:

top left horizon, looks like a flock of birds or insects in the distance.

ArMap, to scale the entire photo to real size.

Tainted, I know this is a little off topic but you have seen some of my math work ups before and TLM ( the living moon ) has not. I work with photo planes. If I know the camera focal length I can figure out how big the picture is if I have 1 known or guess at 1 object. Compare this photo to other knows such a topo maps or other photos and we can develop the 3rd dimension of depth of field. If I can get that, I can reset the photo plane to that area and measure size and distance from the camera.

Or you could use AlgorimancerPG, you just have to give it two photos (from the left and right cameras) and it will tell you the distance to any point that appears in both photos.

With the exact camera parameters it would be possible to do what you want, but I don't know where to find those parameters.

Yes, it does look like a flock of birds, but if you look carefully you can see that they aren't as fuzzy as the rest of the photo, so they are probably bad pixels on the camera.

Looking at the next photo from that camera shows the same black (and the white pixels that are also seen on the ground) in exactly the same places, as you can see below.



So, they are really bad pixels.

Would not Martian birds need bigger wings?

Would not Martian birds need bigger wings?   

Not if they are full of methane.

Same area, is this flight? Sol 2563

Would not Martian birds need bigger wings?   

With a part of the "air lift requirement" being a function of overall weight, then, I guess smaller/lighter bodies might just work with the "standard size wings"! 

[Pimander]

Would not Martian birds need bigger wings?   

For the same reason wouldn't the sky be blue?

[rdunk]

Hey tainted, i salute you, in posting a pic with birds in the Martian sky!! I also salute you for being able to see them, because, I just am not able to see them.

Now I understand! Martian birds must be invisible to the human eye. And, if you can see them, ................. well now tainted, you know what that means?? 

[ArMaP]

Same area, is this flight? Sol 2563

I don't know what that is, but it's not bad pixels.

SOL 2492

Now this is as close to I have come to seeing anything remotely alive or alive looking since the landers fell.
It looks like a dirt mushroom or a dirt flower, there was another one just to the left of it, but the rover mushed it.

[rdunk]

Tainted, that is a good eye, and a good find. Actually, would be hard to really know what it is. One thing for sure, it doesn't look like anything else we have seen on the surface.

One observation, the wheel of the rover did come pretty close to that "anomaly". So, that piece lying a little farther over, could have been broken off of the anomaly itself, then squashed by the wheel. Just a thought!

One thing for sure, we can keep an open eye for more of that thing, as we look at these photos.!
