Victoria and Opportunity from Above, MRO's new color image of Victoria Options

[Jeff7]

Ok, gotcha. Great, now I've got to download another huge image file.

Am I the only one who is amazed at just how much more tangible the HiRISE images are, after all they are only 2-4 times the resolution of MOC. It doesn't seem right to me that they should seem this much more real.

I'm increasingly of the opinion that my guess from the early HiRISE images may be right, that is, that much some of the "texture" we were seing with the MOC was really noise. The comparisons suggest that now we're seeing the same areas with much improved S/N ratios.

At first glance the images look smooth and almost polished (as do some of the images from the HRSC on Mars Express). By comparison, the Mars Global Surveyor MOC images had a more granular or matte finish. I'd always assumed much of that was real surface texture, but now I'm wondering.

Was the MOC "texture" merely noise and are we seeing the promised improved signal/noise ratio from HiRISE?

To the shores of an amber-hued ocean of dreams.

Stu... nning.

All of that.

And... "To the shores of an amber-hued ocean of dreams." is great - I mean, Shakespeare great (IMHO).

[nprev]

Just read your poem, Stu...beautiful and evocative...a very moving testimony to MER and its people.

I only hope that its vision is realized at Big Crater or beyond!

[CosmicRocker]

Yes, Stu. Those were very moving words.

There was an interesting article in a Tuscon Arizona newspaper recently about the "fine tuning" of the MRO imagery, especially with respect to Victoria. I can't wait for the stereo. The sweetest part is at the end.

"We are processing, trying to get things just right, get everything perfect before we release things," Eliason said. "Let me assure you, we are the people's camera, and when we get our ground system operating, and when we get into some orbits, we will be releasing our images on a regular basis."

Only some 214 meg for the jpg..... rougtly 25,100 by 35,500 pixels....

[djellison]

Were they only able to get multispecral coverage over a smaller area?

Yes - the HiRISE detector is 10 CCD's side by side in the red. The middle two CCD's though are joined by Near IR and Blue/Green CCD's as well, so you get basicaly, 20,000 pixel wide images with the middle 4,000 in pseudo-colour.

Any tips on what application to use to try and manipulate that beast of a jpg. The Gimp on my system (IBM T43p with 1GB RAM) reads it in _s_l_o_w_l_y_ , thinks about it for quite some time then tanks. Something to just chop it up into 100 2meg chungs would be a good start.

[djellison]

More ram is must to be honest - I'm on 2GB and can just about manage it. Considering XP+Photoshop or GImp is probably taking half a gig....then going from 1GB to 2GB actually trebbles the ammount of memory available for the file within gimp/photoshop etc.

I wonder how much science we can get from those views of the Rovers & All from above. I'm surprised by how "clean" Oppy looks like. I was expecting she get some colours from the dust and be more "integrated" to the scenary. Here are more questions I ask myself :
1- Oppy landing base didn't probably get some cleaning events (?) how she'll look like since last picture ?
2- Will be interesting to compare Spirit's desk from above to what we see on the ground AND what we see on the sundial. I guess she'll look like quite "red".
3- How "red" will Viking 1 & 2 look like?
4- Same question for Pathfinder

Now, in another thread I bet we'll see Oppy shadow and I was (nearly) right. What can we exactly see from Oppy's shape. To my eyes, there are two "bulges" behind; or, is this the HGA?

I was away last week and I must admit that my vision of Mars changed completely, thanks to MRO. We'll all have a very new vision of Mars in the next months. Lot of discoveries to come guys...

Just finished downloading the monster and came to the same question.
I was able to open it using IrfanView and it took quite a while (it seems as the tool was absorbed by the stunning picture and saying "wow!" too and forgot to finish it's work. ) I don't think my image editor (Serif PhotoPlus) will be able o manage that.

[Tesheiner]

I think this is "jammerbugt" where we got stuck on Sol 830

Right on the money, Sunspot.

Northern Erebus and monster Dunes. Remember these?

Yep.
And here you can see the rover tracks (between the black reference lines) between sols 619 and 631.

And even off-nadir they hit the bullseye with what has to be fantastically precise slew control.

If you don't mind a bit of hacking, ImageMagick can do it.

See earlier in the thread for identification in the HiRISE images of: Purgatory identified by Jason. Jammerbugt identified by Sunspot. The colour section only covers the central portion of the HiRISE swath.

I just want it added for the record, I was the one who found pergatory, with Jason's help. We were both in the PIRL lab (Planetary Imaging Research Laboratory, the place we both work), and he had the desire to find it. But it was I who found it in the end. Not that it really makes any kind of a difference, but... We were all actually really surprised to find that Jason was so interested in a Mars image, he blamed it on a cold he had recently gotten over.
