NASA Mars photo leaked - wood found on mars!, page 3

Wood warps when it gets wet. Go to Home Depot or Lowes. Look at the 2x4's and try to find ten that are perfectly straight out of the hundreds in stock. Good luck.

But....the premise was that it was a piece of wood because of how perfectly straight it was. Now you are saying it is wood because it is curved. Awesome, what is next? It is wood because it is a rock?

No, you need a fluid - either a gas or a liquid, preferably holding some sort of load (thereby exposing said rock to attrition). Seeing as Mars has an atmosphere, and the winds on mars are full of small particles of rock, it has abrasive properties.

Here's my take, in this photo panned right you can see another outcropping with a grain in the same general direction as the supposed "wood." Because the edge is more jagged though it's easier to distinguish it as a rock outcropping:
marsrovers.jpl.nasa.gov...
Furthermore, in this photo note how opportunity's tire marks show that it drove right over the "log." If this were a real piece of wood or petrified wood, it would have rolled when the wheels hit it, yet the tread marks show that it didn't budge or it would have jammed opportunity's tires and smeared the tread marks. Lastly, when you look at it closely in stereo you can tell that the "log" is just the exposed edge of a larger outcropping of rock, kind of like an old sidewalk with a section that juts up at a high angle.

This is a cross-eye stereogram of the outcropping cropped from the full res images of the left and right eye cameras. Cross your eyes until the images overlap to see it in 3d. There should be 3 images when your eyes are crossed properly and the middle one will be 3d. This clearly shows that it's just a rock outcropping and nothing unusual.

Now I have a headache.
Thanks a bunch.

If this were the only piece of whatever that resembled a piece of wood,being fairly long and straight,it wouldn't mean as much.But in the same panorama I found live and fossil animals that seemed intensely curious after the rover hit it as a speed bump,and they literally surrounded the rover. It woke up the neighborhood. www.itv.com... Here's a new show called Primeval about wormholes and time travel where species of prehistoric times and future times are represented as coming to life in our present. Funny how the WORMS episode remindsme of Life on Mars because of all the crawlers living and fossilized,as I have explained for 5 years. I just stopped myself from reposting 3 pics of the "wood plank "crater" so I don't get banned for 2 weeks again for a double post.

By using no filter (the L1 position) the sharpest image with the greatest dynamic range is achieved. It is also useful in low light situations.

Thats true becaues there is nothing between the scene being photographed and the imager in the camera.

What is curious tho is that the primary missions of the rovers are geological. If I was to want to know as much about the geological aspects of a planet, and come across something like this, I would start spinning that filter cap like crazy to those geological filters to get all types of data on the rock/wood.

But thats just me..a simple joe public guy who is no geologist or scientist or NASA official.




Cheers!!!!

(..whos to say they didnt and we just dont know becasue they are hiding said filter data)

Also, that's a navigation camera image, no filters at all.

Hmm...also its curious that when they use the "L1" slot, which is empty, has no filter just a clear lens, the file names usually have "L1" at the end of the file name. In those images, they all say "L0" or "R0"..R being the right side camera and L being the left side camera.


Hmm....I just thought of something..gonna test my theory. Will advise.




Cheers!!!!

Again, that doesnt make sense to not use the camera with the filters to get geological data on a geological mission that encounters a obvious geological anomaly and only use a simple nav cam for taking simple b/w images of said geological feature????

My error they did list it in nav cam. Still doesnt explain why no data imagry at all however.

Another curiosity.

Never Adds So Absolutely.

Look at the other navcam images. There are other similar stones in the area. My guess is that the drivers were all lot more concerned about the edge of the crater at that point.

Well thats a "fairly" plausable explanation as to avoid a hazard. But I dont see any hazard before the rock/wood object as the tracks show, the thing drove over it. They knew this thing was going in that direction and the on-board computer doesnt just interpret commands or process images, it uses the hazcam to help navigate in between the navigation commands sent to it by the ground. If it senses something, the thing will stop before something happens.

Not Any Sensible Answer.

From what I understand in reading the specs on this rover, and I am an engineer so its not rocket science or unfamiliar to me, this unit has the ability to say "NO I WONT GO". In other words, it uses the hazard camera to "sense" an obstruction as it moves along the pre programed course sent down to it by the ground command here on Earth. The ground drivers are not always able to see very far ahead when they plot the course and program the rover to follow that course.

Knowing they would have this situation, they built this thing so that it was smart. The computers on board would follow the course plotted into them, but they would also refer to the real time hazcam data as it travels. This avoids any potential risk of the rover diving right into a hole or over a cliff that the operators could not see prior to programing a navigation course.

Pretty easy and not so complex to understand or implement either.

Here is the nav cam shot after the rover went over the rock/wood object.



Full size HERE.



I have highlighted two points in yellow circles with text. These are the two turn points where the rover turned to manuver towards the rock/wood. And the rover obviously stopped to make its turn at the first turning point. Why is this so? Becasue if you look closely, you can see the tracks at that point do a complete 360 circle in the dirt, meaning the rover rotated a full 360 degrees to get a full 360 degree circle view before proceeding to turn point number two, where it did a near 45 degree turn and then one side of the rover, the right side wheels, went over the rock/wood object.

So my point here is that not only did the operators know that this rock laiden area was approaching by the 360 degree rotation of the whole rover to get a view of everything around it, they knew that this rock/wood thing was there because the distance between the rock/wood object is not so far that they did not see it comming when the rover did its 360 degree view rotational turn at turn point 1.

They programed this rover to head towards the rock/wood object, then do another stop, which may or may not have happend, but certianly at turn point number 2, they did a 45 degree turn to the left to go over this object with the right side wheels of the rover.

So they knew it was there. This rear view hazcam view shows that after they went over the rock/wood object and parked just short of the cliff, the rear of the rover shows not one, but two of these rock/wood objects.

Image HERE.

With knowing that this very unusual geological feature was there before navigating up to it, running over it, and stopping after doing so, that there is reason to accept some mudane reason that they were worried about going over the cliff when obviously they had pre-warning of that when doing the 360 degree rotation view at turn point 1, and not even bother to stop before running over the rock/wood object to "break out the goods" and study this thing closely????

Well as some skeptics like to say...I say..."BULL"!!!

I am sure they did. They are just keeping that data from us. Probably because it very well MAY BE a petrified piece of wood.

Why else wouldnt they bother to get a closer look when in no other imagry from ANY other rover has EVER encountered such an object like that before????


Curious.


Never Admitting Serious Anomalies
