I've been struggling all evening, to manipulate the full size version on my poor old computer.
Now it's getting late, so it'll have to wait. In the meantime here is a lower resolution (about 1/4) first draft.

I believe that with this done that is full mission success for SSI. Congrats Mark!

Beautiful! It is amazing to see the full site. I can't wait until the PDS release, when I can go to work on the horizon.
Posted by: glennwsmith Jun 25 2008, 02:05 AM
Very nice work James. And this wouldn't look out of place on the cover of a science fiction paperback from 50 years ago!
Posted by: Astro0 Jun 25 2008, 07:35 AM
Wow James!
Here's your image as the coolest of cool Polar_Polar Pans. A Polar Peter Pan perhaps! 
Can't wait until we see this filled in....extra cool!

Well done James (and well done Mark)! This is one of the things we have been waiting for. When we get the full res I'm, probably going to print it on a polymer film and make a real wallpaper out of it for the side wall of my study.
Thanks guys 
Posted by: Doc Jun 25 2008, 10:22 AM
Absolutely stunning! 
Compliments to jamescanvin and congratulations to the SSI team and 3 cheers for Peter Smith for making this all possible.
Posted by: tedstryk Jun 25 2008, 02:55 PM
Do they plan to fill in the lower tiers?
Posted by: ugordan Jun 25 2008, 02:57 PM
I don't see why not. This is not the actual complete pan, yet.

"Phoenix camera team leader Mark Lemmon cautioned me that the mission success panorama isn't really quite done.... they plan on filling in the terrain nearest the lander, which includes the robotic arm's workspace".http://www.planetary.org/blog/article/00001522/
Posted by: ElkGroveDan Jun 25 2008, 03:17 PM
That has got to be the cleanest of all the polar pans we've done around here. I could gaze at that all day.
Posted by: fredk Jun 25 2008, 03:28 PM
Stunning job, guys. There's something eerie about that disembodied robotic arm floating there, too. 
Posted by: Cargo Cult Jun 25 2008, 05:38 PM
A random, meaningless point on some near-featureless, empty, frozen northern plains on an entirely uninhabited planet - which has now become the centre of the universe for a vast, varied team of people. Fantastic!
(It reminds me a little of the http://en.wikipedia.org/wiki/Degree_Confluence_Project - precise locations you'd never give a second glance gaining some strange significance through external factors. This odd little spot on Mars, seemingly identical to its surroundings for many, many kilometres, is now important. And will be photographed, prodded, dissected and analysed, because everywhere is interesting.)
Posted by: tedstryk Jun 25 2008, 07:50 PM
I played around with the hills a bit. Considering the quality of the data, they are remarkably featureless.
|
Posted by: ugordan Jun 25 2008, 07:53 PM
Not surprising considering flatfield noise, jpeg compression artifacts and plain dust in the air.
Posted by: tedstryk Jun 25 2008, 08:40 PM
It is just that hills at other landing sites were so much rockier, even in poor quality imaging.
Posted by: ugordan Jun 25 2008, 08:43 PM
That's probably because these are more distant than say the Pathfinder Twin Peaks.
Posted by: tedstryk Jun 25 2008, 09:31 PM
That's quite possible. I really don't know the scale. It will be interesting to see once better quality imaging is down.
Posted by: fredk Jun 25 2008, 10:00 PM
I'm not sure about Twin Peaks, but the low hills in tedstryk's post above are about 20 km to the SSW. There's a large crater a similar distance to the SW of the Columbia Hills - this shot shows it:
http://marsrovers.jpl.nasa.gov/gallery/all/2/p/606/2P180161224EFFAEM9P2629L6M1.JPG
Of course its visibility varies a lot with dust levels. Here's a more recent winter view with clear air:

Another draft. I added in the arm work volume mosaic from the first week, unfortunately they don't quite overlap.
Also available at twice the resolution compared to yesterdays (half of full)

Or how about as a "don't panic" emoticon? There's something oddly familiar about that polar image... (Or perhaps just something odd about me...) 
Posted by: 3488 Jul 1 2008, 01:16 PM
Great imagery James Canvin & Astro0.
Wonder how they'll compare to the official ones that will be released by NASA? My own thoughts are that the first 360 pans should have been the priority for the first few sols, before unstowing the arm & digging. That arm is quite an intrusion.
Can I ask, what software was used & is it expensive?
Thank you.
Andrew Brown.
Posted by: BrianL Jul 1 2008, 02:25 PM
The arm adds a certain je ne sais quoi for me. In retrospect, maybe the first Spirit panorama should have had the arm outstretched and pointing toward the Columbia Hills a la Babe Ruth, as if to say, "There. That's where we're going".
Happy Canada Day everyone!
Brian
Posted by: jamescanvin Jul 1 2008, 03:19 PM
Thanks.
Having the arm moving about is not too much of a problem. They have already retaken a few of the images in the near field when the arm was in the way the first time.
I use Hugin to stitch the images (free open source
) and usually the GIMP to post-process (touch up saturation/brightness etc, add credits, save as jpg, etc.) (free open source ) However for really big images like full resolution 360 degree pans the GIMP really struggles and I then use Photoshop which can handle these much better.All the matching between frames is done using a program I have written myself from scratch which while has not cost me anything in monetary terms has cost me more time than I even want to think about over the years!
James
Posted by: jmknapp Jul 1 2008, 03:30 PM
I was trying to manipulate some large images (planet texture maps 21k pixels wide) & the ImageMagick library on a RAM-challenged old Linux box was just crashing. There's a JPEG2000 format or something which is supposed to facilitate handling large images at differing crops and resolution, but I haven't looked into that. A simple (although slow) stopgap was to create a much bigger swap file so there was enough virtual memory, & it eventually chugs through (in that case splitting the big file up into tiles).
Posted by: 3488 Jul 2 2008, 12:31 PM

Thank you very much for your answers James. Very much appreciated. I must try & few more things myself. I will be keeping an eye out for further interesting images.

Do they plan to send back a panorama composed of lossless images like they did with Pathfinder later in that mission?
Posted by: djellison Jul 2 2008, 10:13 PM
There is a plan is to conduct a lower compression, more filters, less down-sampling pan as I understand it ( called the Re-Peter Pan ) Of course, with Pathfinder, it had 1/16th the resolution to contend with.
Doug
Posted by: 3488 Jul 2 2008, 11:20 PM
Hi Doug,
That is going to take some time & a huge number of frames. Is there enough time left in the Primary Mission to accomplish that?
What would be interesting would be a horizon pan at around the time of the Midnight Sun, do determine atmospheric light scattering, etc.
Andrew Brown.
Posted by: Astro0 Jul 3 2008, 01:21 AM
A crude attempt at filling in the deck and panels using the ground-based test images.
The real thing should be spectacular!

WOW! Beautiful job, Astro0!
Posted by: jamescanvin Jul 3 2008, 07:10 AM
Great job Astro - I'm still working on getting the deck pan added to The Peter Pan
Doug - Maybe I'm wrong but I thought the name Re-Peter Pan was just applied to the the repeated bits of Peter Pan where there were dropouts in the data the first time around.
Andrew - yes it will take quite a long time - it depends just how much compression and how many filters are used - but I could imagine the horizon pan being done by the end of the primary mission.
Posted by: djellison Jul 3 2008, 07:35 AM
Ahh- that makes more sense.

BBC's The Sky at Night did a great job - sent Chris Lintott out to Tuscon for a day or two and had a brilliant half hour program on BBC4 just now.
I noticed something in the background of an interview....

Notice anything cool? A nice big print out of an early chunk of the Peter Pan in there.
But it's not the NASA version - http://www.nasa.gov/mission_pages/phoenix/images/press/S_016IFF_CYLTST11E1C_RAAAM2_newer.html - see, no black borders.
It's this one - http://www.nivnac.co.uk/mer/index.php/2008/06/11/phoenix-16-r1bc-6-pointings
It's JC's mosaic on the wall at PHX HQ.
Like an art insurance specialist - it's all about the border
A flick comparison for added 'Bloody hell, you're right'There you go James - that's twice you've been on the Sky at Night now

Posted by: jamescanvin Jul 7 2008, 07:58 PM
Pan on the wall at Phoenix HQ and on Sky at Night at the same time. Doesn't get much better than that! 
I notice that in the first shot from inside the HQ at the start of the program you can see it on the left on the other side of the room. Gives a bit of context to it's location.

Just chatted with Mark Lemmon -- he said that as of this morning he's declaring the Mission Success Pan to be complete (in terms of data acquisition). He said there's one or two things he'd like to go back and do, like get the part of Mars above MECA that was blocked by the arm, and maybe do some imaging with the arm in a position in the work volume like it was about to do some work, but the data bits are down for a full pan.

Posted by: akuo Jul 9 2008, 12:53 PM
Are there plans to cover the area hidden behind the meteorology mast? Maybe with the RAC? :-P
I guess most of the area under the lander could be similarly imaged...
Posted by: jamescanvin Jul 9 2008, 01:01 PM
Yep, a test version I made last night was only missing one image and I see that has now been taken and downlinked. Hooray!

Disabling image compression is less of a benefit than full, but compressed frames would be. It would be similar bandwidth-wise, given a 4x compression ratio.

We now have an unobstructed view of the crater rim on the horizon to the west, which had been partly blocked by the arm:

Posted by: 3488 Jul 10 2008, 10:47 PM
Crop & 3 x enlargement of hills at Azm 278 deg Sol 44.
Is that a small impact crater at the bottom just right of centre at the bottom of this crop?
|
Also, are they boulders on the hills, if so there are more larger pieces on the hills than on the tundra plains that Phoenix is situated on.
Does anyone know what these hills are? I assume crater rims?
Colour crop of same hills from Ant103 superb colour image. There is a huge amount of talent on UMSF.

Phil Stooke identified them as feature "C" in the maps http://www.unmannedspaceflight.com/index.php?s=&showtopic=5249&view=findpost&p=118879 It looks like a crater from orbit.
Posted by: jamescanvin Jul 11 2008, 08:02 AM
Still got quite a bit of work to do on this. (My software was never designed to do deck pans, I've never attempted an MER one). But the rest of the view is too good to keep to myself, so here is the latest test version:

Posted by: TheChemist Jul 11 2008, 12:16 PM
Great view guys ! However, here it comes:
Stupid question of the day for the imaging gurus:
How difficult is it to make a rotatable polar view ?
I like the perspective of polar view images, but I find it impossible to grasp the entirety of the horizon without rotating the laptop or my head to pain-enduring positions. I've seen VR movies of normal 360 deg. panoramas posted in UMSF from time to time, and they were gorgeous Can the same be done with polar view panoramas ?
PS. I know about rotating the panorama in image viewers, but this does not quite do the trick.

Posted by: punkboi Jul 12 2008, 02:51 AM
This is the part of the panorama that I'm gonna crop for that 8X10...
The only qualm I have with the mosaic is that a part of the robotic arm scoop can be seen next to the solar panel to its right (shown in that white bracket). I can Photoshop it out myself...but I'll just wait to see what other changes you make to the Pan in subsequent versions

Posted by: DDAVIS Jul 12 2008, 04:52 AM
'I'll just wait to see what other changes you make to the Pan in subsequent versions '
Here is what I could fill in from earlier photography which can be pasted over the Canvin version of the color pan. Alas, the earlier pan also had the arm blocking part of the view. I made a rough color match of the earlier grayscale images without any attempt to recolor rocks, etc. I hope the plans to re shoot those parts needed to provide a clear panorama bear fruit!

Yes I noticed that. Remember that these are all quickly thrown together test versions I'll cut out some bits of arm (there are others) for the final version. They have retaken the bit with that has the arm in (see post 60), but I'm inclined to leave it in my version.
Posted by: 3488 Jul 12 2008, 04:55 PM
Can I say an enormous thank you to everyone in this thread who has posted work of the utmost professionalism, that even NASA themselves are going to find extremely difficult to usurp.
You guys bridge the gap between Science & Art very effectively & put certain 'artists' to shame who think unmade beds or a flashing light is art. The work you guys do is worth vastly more & are part of the long term investment of our species.
It would be great James Canvin for two versions of your remarkable pan. One with the arm in place & one with no arm, showing the complete Martian Landscape in Scandia Colles without any obstructions.
Also the Sky @ Night was repeated at lunchtime today & yes your work was on display at Mission Control.
This is most certainly an interesting site, both scientifically & visually. I for one will study the pans intently.
BTW where in the UK are you from James? It is a great website you have there James.
I have put in requests for midnight sun observations, perhaps a timelapse movie of the sun swooping low over the northern horizon, the first ever such observation from another planet, also due east, west & south observations on another sol but at the same time, to get a differing illumination on the landscape. Also is not Holy Cow supposed to be imaged with illumination from the midnight sun at some point?
James, I wonder what you could produce from said observations? No doubt, would be mind blowing.
Andrew Brown.
Posted by: 3488 Jul 12 2008, 05:07 PM
Thank you very much Fred for your answer & to Phil Stooke for taking the time & trouble to pinning down what we are looking at.
That crater appears to have an interesting polygonal floor. To me it looks more like a Pingo than an impact crater, though it's size appears too large for a pingo, unless they can grow much larger under the 37.8 % gravity?
Please keep up the great & very important work everyone.
Andrew Brown.
Posted by: jamescanvin Jul 12 2008, 09:21 PM
My final version. Unless I do one with the arm removed, personally I'd rather see someone put the missing part of the arm in!

(Smaller versions available as well )
Posted by: Oersted Jul 14 2008, 05:24 PM
Wonderful panorama, woohoo!
A few aesthetic comments:
- we really need that arm to extend out to the edge of the image, blotting out a bit of fake sky is no issue.
- I also definitely vote for the panorama to keep the arm. It is true that it obscures a tiny bit of the horizon, but let's face it: one bit of this landscape is pretty much like any other bit, so not much harm is done. The arm is very necessary to include in the pan, it is after all the main instrument of the mission!
- the area immediately around the arm needs to be brightened a tiny bit (obvious from the thumbnail). There's also another splotch near the middle that seems a bit too dark.
Posted by: Oersted Jul 14 2008, 06:47 PM
Woohoo again! - I just noticed you made mainstream internet media James:

James Canvin's polar projection overlaid on a false color HiRISE image:
|
Features at the 5 m distance ring from the lander mast have been coordinated.
It is interesting is that by comparing to wider range HiRISE false color views (Sol 3 and onwards, Post 47, link http://www.unmannedspaceflight.com/index.php?s=&showtopic=5175&view=findpost&p=116092), it indicates that most of what we are seeing (at least out to 20 m, which is close to the visible horizon in the mosaics) at the surface has been slightly altered by the lander blast. In most of the visible fore- and mid-ground, the "poofy dust" has been blasted.
-Mike
Posted by: Juramike Jul 18 2008, 03:42 AM
From the HiRISE images it appears that the local terrain around Phoenix has been significantly darkened. I was curious how to correct the view for a "pre-landing" (read pre-retro blast) view.
I used the IRB[=RGB] images hosted on Emily's blog (http://www.planetary.org/blog/article/00001557/) to calculate the darkening effect in the local area around Phoenix.
I selected two representative areas in the HiRISE images, one near the Phoenix spacecraft (inside the blast zone), the other beyond the obvious blast zone in the false color image. Both areas needed to be fairly uniform (and easy to find) in the images. They correspond to the central section of the smaller polygons.
|
Next, I used the selected zone Histogram function in Photoshop to find the average brightness values (on a 0-256 unit scale) of the pixels inside the representative zones for each channel image. Note that the differences in the I[R] and B[BG] channels are within the standard deviation of the values.
|
|
|
Figuring the difference as a function of the measured brightness, I *think* this is how to correct the view of the Phoenix mosaic to the pre-landing colors
These numbers are in reference to the HiRISE instrument detector response in the IRB channels, not to the Phoenix imaging camera!
|
To correct the Phoenix surface mosaic to pre-landing colors:
- Add 5% to the IR brightness
- Add 11% to the Red brightness
- Add 15% to the Blue-Green brightness

Hi,
From the great James Canvin's Peter Pan, Ive added an full synthetic sky to show the sun in approximative place at 12:00 of the landing site, with its elevation at this season. And this is for showing the way martian sky could be. Hope you will like it, in particulary James .
Without clouds

Nice.
I don't understand the sun position though, wouldn't it be due south at 12:00?

Yes, but, honnestly, I've placed it by seeing shadows and reflection on the deck. But, is it strongly possible that I've made mistakes.

Hi guys, great images as always.
Can I help by posting these charts I've made on Reshift of the Phoenix Landing site on the Solstice on Sol 30?

Ah, OK, thanks Ant, looks good whatever time of day it is. (mid afternoon I think )
Posted by: Stu Jul 19 2008, 04:28 PM
Don't worry about it
I know mega-accurate images are important, and your Sun position might well be "off", but sometimes you just have to push "accurate" aside for the sake of a shamelessly dramatic and attractive image that captures the mood and spirt of a scene and evokes a sense of wonder. Your image does that. Stu (uncrowned King of unnecessary lens flare and over-the-top lighting effects!!

Thanks Stu
Doug : great QTVR. I don't know how to do it but I really appreciate it .

Doug, magnificent! That MET-mast realy comes to live.

Here is The Peter Pan projected to a Vertical Projection, suitable for overlay on top of HiRISE images or simply for a birds-eye view:

Nice.
Posted by: BrianL Jul 23 2008, 09:00 PM
Hmm, from that perspective Damocles might be a better name for the lander.

DOUG!
you're killing me!
Fabulous! Thanks

Upsidedown?
I think north is at the bottom of that image.
Posted by: jmjawors Jul 24 2008, 05:37 AM
Phoenix appears to be under attack by some sort of giant claw!
Awesome perspective... what an amazing image (all of them).

NASA TV showed this image of the Panorama. If that's the official, 'complete' version... Then I guess I don't have to worry about replacing the 8X10 I made from the Pan that James did.

NASA TV showed this image of the Panorama.
Whish has been released as PIA11007
But at low resolution. Will a larger resolution version be released?

I think http://phoenix.lpl.arizona.edu/images.php?gID=17106&cID=193 gets you to the press release page at the LPL site and you can select for download the 61MB version on the right
Posted by: ugordan Aug 6 2008, 01:25 PM
Looks to me that 61 MB version is magnified and it's not higher resolution than the "medium" res, 24 MB view since the panorama was taken in 2x2 binned mode.
Posted by: Paul Fjeld Aug 6 2008, 01:30 PM
Interesting. Why would they up-rez the thing?
Posted by: jamescanvin Aug 6 2008, 01:36 PM
Err, no. The green/blue were 2x2 binned but the red was at full resolution. (except for the deck which really was down sampled but their version doesn't include that anyway)
Hence why mine has similar dimensions to their large version. 26642 vs 26720 pixels for the full 360
Posted by: ugordan Aug 6 2008, 01:49 PM
Not true. All 3 filters were taken in 2x2 binned mode with the additional red frame (far red L1/R1) at full res, the one you're talking about. I'm not seeing the full res view used in the official version. You be the judge if this looks like a full res view in terms of crispness (of the red channel at least):
|
using the red channel from this image: http://www.met.tamu.edu/mars/i/SS015EFF897559394_11E1CR1M1.jpg
or rather this one: http://www.met.tamu.edu/mars/i/SS015EDN897559215_11E18RAM1.jpg
Counterintuitively, the binned frames are actually more blurry than full frames, one would not expect that given that binned frames depend less on camera point spread function. It's certainly not the case with say Cassini or MESSENGER binned imagery.
Posted by: jamescanvin Aug 6 2008, 02:36 PM
Well I would argue that that it was a true statement - I just omitted (forgot) the other red channel.
When you originally posted I only let the large file load as far at the met mast and that looked good to my quick glance but looking at some of the terrain does indeed show that a lot of detail has been lost compared to my version. How odd...
Posted by: fredk Aug 6 2008, 03:56 PM
I've wondered about that too. My guess was that the binned frames used a more lossy compression than the full frames. The SSI site talks about jpeg and Rice compression. The binned frames don't look like they're heavily jpeged, and I thought Rice was lossless, but a simple modification of Rice would effectively act like a spatial low-pass filter on the images, if I'm correct. That could explain what we're seeing.
Posted by: elakdawalla Aug 6 2008, 10:44 PM
Mark Lemmon clears up some of this...the short version is, no, you're not crazy, the binned images really are blurrier.
Second, there are more elements to putting the pan together than I can speak to. One element that I can, is that I never had time to use and check the upconversion routine (recovers full res from the binned images quite well) on all 300-some binned frames, and some form of simply scaling the images up was used instead, to the best of my knowledge. Phoenix is amazingly complex to operate, and the team is simply not big enough to be able to operate it well and do all the processing we would like. Doing the best job we can with the images is something that has to be deferred.
Third, I would expect a better version of same pan (better includes filling in the black spaces). That won't come until the ops pace has eased, certainly not until well after the disruptions of the next few weeks. In addition, the HEA pan has no binning, less compression in all filters, and little compression in stereo filters.
Hope that clears things up!

Hi,
I recently made a James Canvin's Peter Pan version for Stellarium. Very helpfull to see where is the sun and view when it will "touch" the ground .
http://www.db-prods.net/blog/wp-content/uploads/2008/08/phoenixlandingsite.zip
Installation procedure are described in the read-me .
And screens :

Today midnight sun

Hope you will like it (if you are user of Stellarium)
Posted by: Hungry4info Aug 11 2008, 05:11 PM
That's really neat! I've used Stellarium before, it's a nice program. Is there any way to change the colour of the atmosphere?
Posted by: Reckless Aug 11 2008, 09:55 PM
Hi James
I've dragged the file and clicked on the landscapes tab but just get a list of four landscapes and no "Setting landscape updates the location" and choose "Mars". to cross this is in windows vista
Roy
oops old version of Stellarium, now downloading 0.9 this one should work thanks.
well tried that and have crossed the "Setting landscape updates the location" but still nothing happens.
Posted by: Reckless Aug 11 2008, 11:00 PM
Hi James again
At last I've got it going, instead of dragging the file into texture/landscapes I dragged it into another landscapes folder that is at the same level as textures and not inside it.
Thanks James it looks great, now I'm off to play with it
Roy
Posted by: Hungry4info Aug 12 2008, 01:56 AM
Lol I redownloaded Stellarium just for this (I had uninstalled it a while back), and am not sorry I did, lol.
Very nice work!
Posted by: Astro0 Aug 12 2008, 02:10 AM
Yes, this works beautifully.
FYI - as Reckless said, for PC users put the 'PhoenixLandingSite' folder under \Program Files\Stellarium\landscapes\PhoenixLandingSite and then the rest of the steps as per the instructions in that folder's document.
Ant103 - this is absolutely excellent and I have already used it today in an outreach talk. Very effective! Thanks.
Astro0
PS: For anyone who doesn't know Stellarium get it http://www.stellarium.org/
PPS: Ant - I hope you don't mind, here's a little tweak of the PeterPan to which I've added the phantom robotic arm just to make Phoenix look complete.

How it looks...

Thanks .
Astro0 : happy to see that it's usefull for you . And really like the adding of RA .
Posted by: Enceladus75 Oct 25 2008, 02:50 AM
Those are simply astounding images guys - well done!
Two things - are there plans for another panoramic grand image just before Phoenix's mission ends in mid November? It might be useful to see any emerging ice/frost on the ground, cloudier skies and compare with the earlier images.
Another thing that has been niggling at me. Where precisely is Phoenix in terms of its regional location? I mean within a 30/50 km radius? Has anyone precisely determined the distant hills/craters seen from Phoenix and thus determined their and Phoenix's location? Can the rim of Heimdall, the crater seen in that spectacular shot of the landing last May, be seen in the distance from the Phoenix landing site?

There is a lot of information on the landing site in this thread http://www.unmannedspaceflight.com/index.php?showtopic=557&st=0&start=0
