Here is an L2 preview of the color pan being taken right now. I just started working on the color images for it.

Seriously, it's a great mosaic - any chance you could post a non-April Fools' day version?

I suppose.

Here are two reprojections of Jan's latest panorama. I'm experimenting with different geometries. I still have to figure out the orientations so they differ a bit.

It seems there are also clouds (or dust) on the top left in the same scene

dark version:


clouds are also on sol 4320 and 4332

Jan's panorama in circular form. This is mainly useful to show the pattern of outcrops around here. It would be nice to see a map of the entire valley floor done like this.

I like it when I don't have to do any processing to bring out the clouds, like in tosol's navcams:
http://qt.exploratorium.edu/mars/opportuni...0M1.JPG?sol4336
Hopefully we'll see more - maybe even like in the early days, when we had beautiful views like this:
http://mars.nasa.gov/mer/gallery/all/1/n/2...B5P1910R0M1.JPG

Stitched together two of the frames with clouds in them from Sol 4336, then added a few frames from the post drive panorama on Sol 4334 to fill out the foreground.

Wonderful pics guys.

James, I don't see how you filled in the data dropouts, I couldn't find any retakes for the ones that had them in mine. Unless you used images from 4336 or other Sol's at a different location.

Here are my version's.

I cheated and used whatever was available to make the colour, so some parts only use L25 or L57 rather than the full L257.

Ah okay, had me pretty confused there.

I couldn't help but add some clouds to this lovely scene.

Added 4 images and look at the clouds.

Does anyone have any idea how to determine at what elevation these clouds manifest?
Terrestrially, the mind tends to be tricked by the appearance of large objects in the sky, and I am often surprised to see a cloud's shadow relatively close by.
I would expect local terrain effects to prompt such clouds relative to the crater rim and so they may be relatively low, despite the cirrus-y appearance, or they could just as easily be far higher as the Endurance crater sol269 example seems to imply and prompted by other effects, as no significant terrain elevation exists there, though this is hardly an earthly analogue we have here..

Interesting clouds. They actually look a bit thin to make that much of a shadow. It's tricky to tell much of the shadow is simply dark surface material. I would suggest those clouds look relatively high up and far away, assuming the structures in the cirrus clouds are of similar size as we see on Earth. Maybe another cloud outside the field of view is making the shadow?

Can you point to what you say may be shadow, scalbers? I'd guess cloud shadows would be very diffuse in the local foreground.

found a couple references to clouds observed by pathfinder being 16 km. MRO spotted some at 42 km. oddly only this old data showed in the search, at least in the fist page, as most hits were about that 'mysterious plume' spotted 2012, so maybe just have to look a bit deeper..



[EDIT] post/pre per scalbers below, hadn't meant shadows actually seen, but was referring to the (just my?) tendency to interpret clouds as bigger than actual, making me suppose the clouds are quite low and thus prompted by the crater rim pushing the airmass above the dewpoint as it passes up over the crater rim, but perhaps the clouds could just as easily be from other interactions. I would agree, there is probably zero chance of seeing shadows from such clouds, at least humanly visible, though visible shadows cast by Phobos, dustdevils, or thicker clouds may be somewhat common.

Right. I was wondering if atomoid was suggesting a shadow being present in much of the foreground of this image:

http://mars.nasa.gov/mer/gallery/all/1/n/2...B5P1910R0M1.JPG

I agree the shadows may be too diffuse to see from this type of cloud.

10-20 km is typical of tropical, aphelion-season clouds. Near the surface, during the day, it is 70-90 K warmer than at night. You really wouldn't expect daytime condensation anywhere near there. Near the poles, clouds levels of a few km to fog are found. There are times when much higher altitude CO2 clouds can be found. Now is the end of water-ice-cloud season; around a month from now is the middle of one episode of CO2 ice clouds, but I'm not aware of any Ls~150 clouds seen from Opportunity. (Some of the early-season clouds seen by Opportunity may well have been CO2.)

This is the most recent of Jan's panoramas reprojected to show the pattern of outcrops here.

It's interesting that the only imaging data available since Sol-4351 is from Mark Powells Mars Images app. I think he is still getting the images for his app from the raw images that are pushed to the Amazon S3 service. All the other data sources seem to be down.

A reminder that Powell has a corresponding website:
https://www.evernote.com/pub/marsrovers/Opp...fc-fee2c99bdef2
But that hasn't been updated in a couple of years.

Does anyone know of a web interface to the Mars Images app images?

I was aware of his Evernote site, but I'm not aware of any other web interface for his app. I'm gonna send him off an email and ask him.
The only work around that I found was to go to the Pancam Tracking site and find an imaging sequence that has been sent down, for example.

http://merweb.sese.asu.edu/merweb.pl?rover...4356p235138%201

Then copy and paste the whole filename but replace /oss to /oss_maestro, sol number and what camera it was taken from ( in this case, Pancam replace in the link with pcam ) as well as change the extention from .IMG to .JPG

Like this

http://merpublic.s3.amazonaws.com/oss_maes...E1P2351L2M1.JPG

Tedious, but works.

No updates to the Exploratorium site since 4/20. Does some server need to be restarted?

You can go through the JSON site which is still working.

http://json.jpl.nasa.gov/data.json
leads to sol list:
https://merpublic.s3.amazonaws.com/oss/merb...e_manifest.json
leads to page for sol:
http://merpublic.s3.amazonaws.com/oss/merb...es_sol4356.json
which has URL to JPG:

Recommend Chrome with JSONView plugin to make links clickable or it is relatively simple to use Python scripts to batch download what you want.

Here are a couple of full resolution false-color preview crops of the ongoing big panorama that Oppy is taking.

I really am hoping Oppy stays here for a while and extends this panorama more!

cant wait for the big pano so heres a slightly distorted stitch anaglyph of sol4368 target brushing

I added the recently released Blender model of Oppy to James' awesome dust devil pano from last month.

The air is pretty clear over Endeavour at the moment, and we are getting nice views across to the opposite rim. I thought it might be interesting to compare the images with those from Cape York two Mars years ago, to see if there were any changes such as a new streak. No - no obvious changes (though using the PDS versions might improve the chances). But it might be interesting to check from time to time.

Agreed! - It will be beautiful with that interesting terrain texture.

Sorry to go slightly off-topic, but I was looking for the folded-up MER dimensions recently, and couldn't find them. Most sites give the unfolded size, but I am interested in the size when MER was inside the lander during cruise. If anyone here has an idea where to find it... Thx!

Perhaps this page can be helpful: NASA/JPL: Spacecraft: Cruise Configuration

Edit: nice article [link] Does the wheel size (26 cm) allow a rough estimate of the base plate size?
And a photo (#3) [link]
Fernando

Obrigado Fernando. I had a look at that page and didn't see the dimensions of the folded-up MER... Will keep looking!

Hope everyone is having a great Memorial Day and Happy Martian Opposition.

Very nice view in James' gigapan! Interesting to see the color variations in the distance between redder and more brown. Helps give perspective to when we look at Mars as a whole and ask, what color is it?

Wow! beautiful gigapan James, that really made my day! here is stereo of that crusty critter from sol4389

There are lots of color variations in the false-color version which I can release as well. I might also get started on a 3D version since stereo imagery was also taken from that spot. I have to subdue those variations when making a "Guestimated" color of what the scene may look like simply because of the filters used, those large color variations would not be as prominent to human vision. The colors off in the distance in the false color version in the crater are saturated light blues, dark blues and some purples, greens and some yellows. I take those blue colors as basaltic in nature,which basalt is blackish. The greens might be olivines. So thats one of the cues that I use when I process my images into picture like this.

Oh and thank you guys for the comments on it.

Here is the colorful False Color version for those interested.

Definitely interested James - that's simply beautiful!

Just out of interest, how long does it take you to assemble a montage like this?

I was putting it together as images were coming down over the several weeks it took Opportunity to take it. To me, I always have lots of fun working with images from Oppy.

Sean that looks wonderful. the rover shadows shouldn't be soft though.

Ah thank you James... I'm still getting to grips with the software. I tweaked my lighting/rendering process to match the shadows.

So here is take2 of my simulated Opportunity with James' wonderful pano...

Well your endeavours are very much appreciated (as is the work of the many other contributors of image-stitching wizardry here).

Those are much better Sean. Fantastic job!
