I couldn't really find any more useful links than the ones Doug already posted above. But, you can see that there is a "horizontal" cylinder next to the lens, and a square cover over it - I believe these are part of the dust cover mechanism. Many of the photos I came across show the MI without this cover installed, presumably for early testing purposes.

The Athena site has a small picture (rendered too!) of the front of the MI:

The 4th picture down on the right shows a (simulated) frontal view of that dust cover.

thanks doug. that mi diagram is very useful. wish i could come across it earlier because as it seems i have to remodel a few things. got me a view of the back side though. smile.gif thanks!

airbag, a horizontal cylinder i have already modeled, there's nothing more i saw in any of the other photos that i did not model. please find a picture of it and post. in the meantime i'll try to find some time to model a bit more of the other stuff smile.gif

thanks for the support guys!

here is the...uhm... 'rear view' of the micro imager.



in a couple of reference pics i've got, i see many differences between them concerning the 'contact sensor housing' this is the best i can make out.

airbag, as for this cap you are talking about maybe it's something i came across in a photo, but since i have 10 without it and 1 with it, i choose NOT to model it smile.gif

hello everyone and merry christmas! it's not that i abandoned the project, I Was just too busy with work and redesigning my new site (so re-visit for new stuff)...

anyway, i did a small progress modeling-wise, but was a great step for the final model. I composited the most of the rat's arm. I have just one render for you guys for now, your support is a great help for me to go on, so I hope you enjoy this one. the next few days i'll try to make the whole arm and finish the moessbauer modeling. hope to hear your comments!

Not sure if the MI is spot on - I think the optic design is a little 'short' - as a reference, the backend and electronics box for each camera ( Pancam, MI, Navcam, Hazcam ) is the same...it's just the optical assemb. that changes...and obviously the MI has the dust cover and contact sensor..but I think these might be a bit too far 'forward'..

hello there... new update. first time to post the moessbauer spectrometer. there's still details to be added but I wanted you to take notice of the progress..



doug, I guess you are wrong on this one, I spent way too many hours analyzing stuff out. I had already checked the reference image you posted but I have to show you the following reference which is one of the crappy ones I used to model. At first I thought you pointed out that the lens was too forward thats why i post the following reference pic, but reading again I realized you meant it is too short compared to the electronics box. it must be the angle though, here is another angle (i know the moessbauers position is totally wrong, currently working on this one)



Moreover as you can see there's no dust cover in the following reference as well. in 8 out of 10 pics there's no dust cover depicted thats why I chose not to model it.



your comments are welcome though, thanks doug, I hope everyone else also helps, I am doing my best here, there are many things that I have remodeled already more than once smile.gif keep checking things out guys! smile.gif

Here is a very nice picture of the instruments, with a particularly good view of the MI's "flip up" dust cover:

well, great news today! I am done with the moessbauer. I had to remodel the metal parts that hold it to its base several times in order for it to be in place (like i did with the micro imager) but not everything seems to be in place! I am also done with the device using all the information I could find in the references I have. the base that holds everything on it seems kinda empty now but I hope after i am done with the cables and stuff (leaving this for the end of the whole modeling process) it will look fine.

enjoy the moessbauer spectrometer in all its glory, although it's a bit out of focus :/



I'll continue with the rest of the arm next, it will be some time before i start it though, very busy lately :/

hello there! long time no see... I hope some of you guys are still patiently waiting to see the progress of the model. here is some progress. I am taking baby steps because my reference material is narrowing my amount of work plus busy with my life :/

anyway, I modeled parts of the arm that holds the rat-moessbauer-mi-apxs system. I am looking for a good SIDE view of the arm, haven't came across any better reference than the one I am posting and this is not at all helpful. I think that the part that is exactly above the bottom round cylinder (one in the circle) is not round and the bolts seem to be held at pairs. in the rear side of the cylindric part (where red arrow points in the circle) I made there's some sort of film held on it - managed to realize that it gets underneath the cylindric part and into the rear part of the right red arrow (shown in the 2nd reference pic I am posting), clear pictures of the rear side -meaning they can provide me with visual info - will be really helpful as well. it is very tiring staring at pictures for hours and not getting any results. Expecting your support guys.

I wish I could help but you are so far ahead of me I just can't even begin to make suggestions on how to help out. For now let me just say - WOW! I wish I could help but this isn't my area of expertise - however I really do hope you get the help you need and you end up giving us some cool shots of your model of our dear lil rovers.

I'm never very keen on "me too" postings, but I have to agree with Helvick. This is a stunning piece of work. I'm sure I speak for all of us when I say we're all eager to see this project develop. It's fantastic.

It's textbook stuff - and needs to find a home in a textbook!

Most impressive!
