Have now implemented this math in my MER filname decoder for "any" desired distance to get the minimum height. Additionally, it can also output the viewing angle in which a given length/width appears in the distance. For example try +50 or +50/6992 in the box full image link or file name code and see what happens.

Thanks to Fred the outputs for minimum height should now be more accurate (at 50km ~370m vs. now ~322m).

Just a bit of fun... not to scale, calibrated or anything fancy like that...

Cool, Stu!

Nice! And by the time we get to Endeavour we'll have more then enough to fill the whole image.

BTW, what's your new avatar?

Tesh: that's an imagined spiral galaxy shining above Kendal Castle, where I do most of my private and public observing. Amazing place :-) Full size: http://twitpic.com/mrtq3

And I'd been thinking more along these lines:

Silly me! (Sorry for the chit-chatty post.)

Back on topic, is anyone else curious where the hazcams are for the end of the sol 2043 drive?

Yes, and I'm anxious to see them, given how short the drive was. I'm surprised (not that it takes much) they turned south there, instead of another SW drive onto more open road.

Re cobbles. Reading a comment on another forum - about piles of cobbles Oppy passed in the past - set me hunting through the raw images pages, and I found this from sol 657...



Fascinating...

That's an image from a long time ago; by the time Opportunity was near Erebus, stopped at Olympia, wasn't it?

Coming back to today's cobbles at our current site and answering to the comments about the hazcam images, they were downlinked together with the navcams for that same sol but it seems we have another bottleneck at the Exploratorium. In any case and reading between lines there seems to be not too much interest in investigating this site. Those hazcams were taken and downlinked with high compression (one and two "bpp" instead of the usual 3bpp) and besides we should be leaving this area right now; due south once again I would say.

Edit: The official MER site is not updated either so the problem might be in the process/server/firewall/whatever which serves the JPEGs to the public sites.

Kind of a pity; I was hoping for an MI or two.

Still...at this point, it's probably time to unless something truly unique is encountered.

Yep, sol 657, as I said. I thought it was interesting comparing it with what we're seeing now. Maybe the well-scattered cobbles we've just seen started off as a "pile" like the one seen on 657, and gradually it fell apart.

That's my non-educated guess too.



Looking at the HiRISE image our current spot has clearly a dark signature and it looks like similar places can be found on the way south on the same image. Let's see.

re the cobbles / meteorites ponderings... take a look at this: http://www.saharamet.com/expedition/CO3/part3.html

It's an account of the recovery of the Dar al Gani chondrite meteorite(s), 180kgs of meteorite fragments gathered up from a "strewn field". Take a look at the 8th picture down the page, the one showing two people crouching down amongst lots of meteorite fragments... looks familiar?

Just wondering...

Well decided to do a panorama out of those Nav Cams on Sol 2020. My first pan! Got a lot more respect for Corel Photopaint - learned a lot and had fun . The first few rungs of an interesting ladder. Could have just kept going on and improving, but decided to draw the line and post it anyway..... Thanks all you guys who've inspired me to get to this point. First pic I felt I could put my name to!
