I dont think we will ever get any proof from Mars where NASA has its hands firmly on the data we and the scientists get to see. You may as well resign yourself to this until someone else gets to the planet and we might get more information. We probably all believe that there is life on Mars otherwise we would not be on here, but hoping that NASA will slip up and we will be there to catch them out is really unlikely. Of course, it does not stop us all enjoying the moment and trying to find stuff others have not yet found in their pictures.

'Proof' to one person is very different to 'proof' for another and when we need to get scientists to believe that there is life on Mars, then we have a very difficult job for many reasons - not least is that any scientist who breaks out of the fold and say that there is life currently on Mars/Moon/whatever, is currently going to be ridiculed and will not get funding for a long time to come. This kind of proof thing has to be a slow process and it is getting many people to edge a little closer day-by-day to the idea of current on-going life on Mars which will eventually turn the tide for us.

Sorry to burst a bubble..

Thanks for that.  Have you guys seen this one?   Its another photo that caught the based of the object (prong and vent section).  

 

Any thoughts on how we can go about constructing some empirical proof using the 3 images (ie.  the prongs picture below and the 2 full images of the object - shown on alienstudy.com)?

If you go to my mars MER search website, using the thumbnail query, you will find that there are 4 photos of this structure. One (filter 7) is far better than the others but each is taken through a different filter and so you could possibly make a colour image of this area.

Camera Pancam
Spirit
sol 1402

link 2
link 3
link 4

It may be a good idea to normalise the images and stretch the greyscales or at least try to make it so that there is not so much brightness everywhere. Once done, you may be able to see some other structures hidden in the brightness.

No ... not netwhoring ... just needed some guidance.   Thanks for the help.  It will certainly come in handy.

Dont be such an attention whore. There are references to your article and twice to your website. You would not be on here just to get visitors to your site would you? In my view this is very poor netiquette and I doubt you will get any attention as a result. But then, I am only a grouchy old man so what do I know?

 

Having said that, there is information on distances and cameras on this thread I started on another forum which may help. It is for Curiosity though. If for MER then I am not sure. There are some knowns such as the width between the wheels etc. which may help with working out a distance.

Can you add a link on this forum to the original please?

Specifically,  I'm getting alot of interest in my article on the metronome.

Many people are asking for dimensions of the object.  What is AA's suggestion on calculating the dimensions  based on the camera specs?
