Hmm - I've used Hugin a bit ( I'm used to PTGui ) but can't replicate the problem you're having.

Maybe zip up the source files and let us try with those?

Many MER large mosaics are done during long periods of forced immobility. MSL, I expect, will have fewer such periods.


I see 31 panoramas here http://pancam.astro.cornell.edu/pancam_ins.../panoramas.html

If you describe 'forced immobility' as being stuck in a dune or huddling down for winter - I see only 6 that qualify. 1/5th.

Long periods of IDD work, long weekends for holidays etc - are things MSL will have also. Doing a full up arm contact science, sampling, SAM and CheMin workout could take a week or two. Given that it took less than an hour to take that M34 panorama - I expect we'll see just as high a sols-between-pans ratio as MER. This team know what they're doing, and they know those big pans are a big win for outreach.

Mike Malin said they proberbly won't be doing another full Mastcam panorama as the science team will be looking at science targets.


Umm - when did he say that? I certainly don't recall that being said in any of the press confs. No plans for a full rover deck pan, but I certainly don't recall him ever saying they'll never do another 360 panorama.

I still see those overhangs as being astonishingly unstable, even in the lower gravity. Watch yourself Oppy!


This outcrop looks about the same size/height as the great wall of Eagle Crater some 8.5 years ago. Nothing the team can't handle.

X-Eye/Parallel doesn't usually work for me, and when it does I get awful headaches. MPO requires downloading the file and then loading it in a viewing app. Anaglyph all the way.

Contact science will be part of the 2nd commissioning phase. I don't believe they'll be doing that here.

There is a model - I'm not sure of its fidelity - at the California Science Center. If there are details there that could be useful, let me know and I'll head over with a camera.

We get data updates every couple of weeks. That's when the last batch of data runs out. You'll be able to find the same thing with many many spacecraft if you look close enough.

We still need an official name for Mount Sharp. I


It already has one appointed by the IAU from some months ago. It's not Mt Sharp, but the team are sticking with Mt Sharp as thats the unofficial name they gave it before the IAU name.

I'm sure they will name something appropriate after Neil when the right thing presents itself at Gale Crater.

So, this will result in a panoramic of about 118 000 pixels wide !! This is HUGE ! Is there computer which can just open such a huge picture ? ph34r.gif I pass my hand…


Easy - just host it at the Gigapan website smile.gif

We already know from the fresh craters found by CTX et.al. that we don't have to wait long for mother nature to do exactly that anyway.

QUOTE (fredk @ Aug 24 2012, 07:46 AM) *
So one guess is we had a good strong gust between these two frames almost erase the tracks.


Looking at this near concrete like surface - it reminds me of desert pavement - ( http://www2.mcdaniel.edu/Biology/wildameri...sertgeolgy.html ) - lots of strong winds over time blow away what little dust is there and leave behind small pebbles etc settled into an almost hard packed surface.

Those winds I'd bet are fairly consistently high, what with a tens of miles run up from the East.

Thus - rover drives over a surface that's not been touched by anything but wind for Gy's - and pushes a few pebbles down, pushes a bit of dirt around. That wind is, very quickly, going to get that dirt out of there and 'rebuild' back to the pavement formation where the dirt is now hidden from the wind between the pebbles.

We saw it happen on tracks we re-visited outside Endurance crater - but here it's just happened much quicker.

GOod point lightning - but one could back out to a location and orientation by using the corners of the images and triangulating back.

For the sake of the four characters of difference between Curie/Curry and Curiosity...I'll be sticking with its full name.

They're just wind baffles. The CHIMRA outlet doesn't dock to it in any way - just gets might close.

Actually - the wheel tracks don't look parallel in that image- they're several degrees divergent as a result of the distortion of Navcam images into the vertical projection.

The descent stage flew away in the opposite direction that we drove - so the behavior on each side of the rover should be the same. Neither pair of impingement plumes is further from rover center. There is a difference in the total dust throw pattern to the ESE because of the flyaway - but that doesn't change the impingement patterns.

You're seing a reprojection issue....go look at the HiRISE image - you can see it's quite different to the distortion induced by the navcam reprojection http://www.uahirise.org/images/2012/detail...B.NOMAP-MSL.jpg

Yes : "Curie" is an excellent idea.
Besides, it would make a lot of sense since the small test-bed "Marie-Curie" rover (the sister rover of Sojourner), named by JPL, was never sent to Mars unfortunately,


I would have thought the fact that there is already another rover with Curie in its name would be a reason NOT to call Curiosity 'Curie'.

Well, there's still the APXS with its half-lives counting down. Eventually integration times will be affected like on Oppy.


You're confusing the APXS with the Mossbauer. The APXS doesn't suffer in the way the Mossbauer does ( at least, not on rover lifetime scales )
