Roving Again pancam.gif 3 September 2007

Today we have published a new panorama from the Opportunity Rover from Sol 1278, stationed at the rim of Victoria Crater and soon to embark on her greatest journey. Prepared exclusively for the 3 September 2007 issue of Aviation Week & Space Technology magazine with the headline "Roving Again" (see story below) as a truly last second contribution.

The unique panoramic mosiac was stitched together from images from the front hazard camera and the navigation camera, which accounts for the noticable horizon curvature and other wordly appearence. This type combo image appears to be a first publication of this type and permitted inclusion of the crater, rover IDD, wheels, tracks, etc.

"The NASA/JPL Mars rovers Spirit and Opportunity are driving again on Mars after surviving electrical power shortages, caused by global dust storms that have swept the planet since July. Opportunity drove dozens of feet back to the rim of Victoria crater last week. The rover took this false color mosaic that preserves details, but sharply distorts elevation to make it falsely appear that the rover is on a hill. The mosaic, prepared exclusively for Aviation Week & Space Technology, was taken by a front black-and-white hazard camera and colorized using earlier Pancam data. Managers hope “Oppy” will finally begin a descent into the crater by late September. This week, Mars is 100 million mi. from Earth. Note smooth rock surfaces under arm. Rover tracks, antenna and solar array are visible (left) and a front wheel (foreground). Cornell University Athena instruments on arm include Alpha Particle Spectrometer (facing camera), German Mossbauer spectrometer (right), microscopic imager (left) and rock abrasion tool (pointing forward)."

Another win for the Mars Rover team and the UMSF forum ! biggrin.gif

Thanks Ken, I would like to add a couple of considerations.

Well, this composition can appear a little disappointing for many... and it is, indeed!
Is an attempt to merge two completely different views in a somewath creative manner.
The most straightforward method would be to transform the fish-eye view of the front haz-cam in a equirectangular picture, then merge it with a canonic, flat-horizon stitch from NavCam. However, this would introduce some evident stretch and loose of details in the peripheric regions of the former picture.
There is another reason why I like this strange view (and not only me, based on the reaction from AWST and APOD): it vaguely recall me some great Escher masterpieces, like this or this...
Clearly, I love this artist and, for sure, I'm not the only one here...

After realization of B/W mix with partially artificial sky, I made a rough colorization and I tried to involve also Bernhard (Nirgal), another mars team member, for a better result. Unfortunately, there wasn't enough time, so we sent my color versions only... next time will be better!

Finally, Ken, you should have something to tell about S.Squire comment, isn't?

Dear Friends, congratulations.
This is clearly one of the best image you've created. I can't wait seeing it on AWST issue (a few more days to wait). I intentionaly use the word "create" since it's artistic, poetic, strange, giving another perpective, .... I just want to put those words in front of Dilo's technical explanations : I can understand how hard it is to reach such a result, I can't tell you how MUCH I love it. smile.gif

This wonderful forum is brimming with so much great talent and enthusiasm. serves as further inspiration to try something different

its a nice addition to the earlier unveiling :

Well done

Well, in a thrilling email from Steve Squyres (please note the spelling Marco wink.gif ), he commented it was "Very Nice !"

I guess having survived from "the Bear" he just lost his words tongue.gif

Marco & Ken, congrats on this achievement!!! I am yet again humbled by the fact that this forum exists & I can actually talk to guys like you... blink.gif

We need a version with The Bear looking at the POV with a speculative, perhaps hungry look, though... tongue.gif

A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

You did it again, congratulations Marco & Ken!
Incredible work, that's really another perspective. A first. cool.gif cool.gif cool.gif

When I saw the attachement on the first post my first impression was "why not a flat horizon?" but then I realized why. It would distort too much the lower parts of the mosaic (IDD, wheels). You are absolutely right on making the curved horizon, it makes for a very very nice image.

Hats off guys.

Edited:

OT: I just went to the APOD homepage to look for your mosaic there --that was my impression after reading Dilo's first post. But to my surprise ( blink.gif ) I found this one: http://antwrp.gsfc.nasa.gov/apod/ap070904.html which was originally posted here.

Congratulations to all, Marco, Ken and Eduardo !
It seems that since the other image was "made exclusively for AWST", APOD went with yours, Eduardo.
I am surprised that APOD implies this is a possible entry point, although it is clear from the TPS link provided (and the discussion here at UMSF) that Oppy will enter on the far side of the bay.

APOD : "Victoria Crater is the largest crater that either Martian rover has come across during their explorations."
