Unmanned Spaceflight.com _ MRO 2005 _ December 20, 2006, HiRISE release
Posted by: Stu Dec 20 2006, 05:14 PM
Anyone else feel like waiting for each new batch of images is like waiting to pull a Christmas cracker? Just don't know what treats are going to be inside! (unless you're tuvas who gets a sneak peek...! 
)

They're http://hiroc.lpl.arizona.edu/images/PSP/release_005.html.

Must've gone up as I typed my note... 
(just looked: how the <chink chink chink> am I going to get through THAT lot before going out in half an hour?!?!?!?!)

I know what they were, because I'm the one who looked at them and made sure they were ready to go. FYI, I think you'll see a similar number of pictures for the next few weeks, we're starting to dump all of the releasable images from Cycle 1, and as there isn't as many people around for the holidays, we decided to take this time to release images without captions, so... Call it a ChristmaHanaQuanza (In the words of our webmaster) give to everyone out there, more images than normal.

Having trouble unwrapping your Christmas gift. Servers on overload?
Posted by: volcanopele Dec 20 2006, 05:51 PM
I thought it was Christmakwanzahanadan.
Posted by: tuvas Dec 20 2006, 06:07 PM
Not in the words of our webmaster, so...
I don't notice anything about the web servers, but I have local access, so... All I can do is suggest patience...

I've only done a cursory scan through this latest release, but I have to say that the lower part of http://hiroc.lpl.arizona.edu/images/PSP/PSP_001388_1565/PSP_001388_1565_RED.browse.jpg is a good example of how HiRISE can document the distribution of small impact craters.
And I liked http://hiroc.lpl.arizona.edu/images/PSP/PSP_001368_1400/PSP_001368_1400_RED.browse.jpg, too
EDIT: With respect to PSP_001388_1565, I should have said "the entire image is a good example..."

Technical phrase is a whole HiBunch of pictures.

I think that might be carrying the HiWords to a bit of an excess...
Posted by: djellison Dec 20 2006, 07:29 PM
Oh - it's far far too late to say that

I've just orded a switch of ISP from Plusnet to a different company... do you think 300-off-peak-Gig will be enough
Doug
Posted by: lyford Dec 20 2006, 10:51 PM
I am impressed at the clarity of even the preview "browse" resolution! And in this image is another good example, though I must say I don't understand how someone as bright as Sir Arthur C. ever thought dunes in channels were "glass tubes/worms."
Posted by: Nix Dec 20 2006, 10:53 PM
Doug
What ISP then. HiGig?
Nico
Posted by: djellison Dec 20 2006, 10:59 PM
Oh, a little company in the UK - heard lots of impressive things about them - Vivaciti...a business bundle with good upload and low contention - But for the purposes of this thread - yes - they are HiSP

AAAARRRGHHHH!!!! 
Even more gigabytes of stuff I want to download and due to a network outage that started 4 days ago I'm very lucky to get a download speed of 5 KB/s, it's usually much worse (1-2 KB/s or less). Worse yet, this now seems likely to last into the beginning of January!! I'm currently downloading the Phoenix landing animation and downloading 40 MB has taken several hours .
$%#&@€#{*^@°$$$%!€@# And this also happened last year on the *exact* day the first batch of Cassini images was released at the PDS and lasted for several days
(sorry for this rant, I just had to vent my frustration somewhere).
I'm seriously considering switching to a different ISP but this is a huge problem because switching to a completely new email address isn't very fun (exception: less spam).
BTW what *is* the download speed you are seeing when downloading HiRISE images? My impression is that it's sometimes rather slow (with "rather slow" meaning at least 10 times faster than what I'm currently getting).

Thanks for that Nico; I was starting to worry that all I'd got in my cracker was a nasty, nostril-pinching plastic moustache and one of those red plastic film "truth fishes" that curl up in your hand...

I have a broadband Cable modem with 10Mbits/sec download and 200Kbits/sec upload
a 1 GByte file loads between 300KBytes/sec and 800KBytes/sec depending on 'mysterious internet loads'
That means I get a 1GByte file down in 15 to 30 minutes (the connection is very bursty - it can zoom up to 1.1MBytes/sec download for a few secs to 20 secs)
The cable is reliable (Comcast); one outage that I recall of less than 2 hours in the last 4 yrs (if its out while I am at work or sleeping -- does it count?)

wowsh!!!!!!!!!! im so glad to be alive
Posted by: CosmicRocker Dec 21 2006, 07:07 AM
Hi, Ya'all, as they say around here.
Ditto, dvandorn. I finally managed to get a copy of the 1.2 gig Gusev image, and now this. Does anyone have some crops to share with those of us damned to dialup?
Posted by: ngunn Dec 21 2006, 09:44 AM
As another soul stuck at the wrong end of the telescope can I add a cropped detail request for that conspicuous little white patch on 001380_2520? (with scale bar if possible)
Posted by: Nix Dec 21 2006, 10:12 AM
You mean this patch of 'snow'?
Nico
edit; now with 25 meters scalebar

Posted by: ngunn Dec 21 2006, 10:21 AM
That's the one, thanks Nico. I can see now that it lies in a shallow basin. It does look very pristine, doesn't it? Probably nothing unusual, but striking in it's lonely isolation.
Posted by: Nix Dec 21 2006, 10:26 AM
You're welcome ngunn, I've replaced it for a version with scalebar included. I immediately noticed the 'lonely' patch too, it's one of the first images from that batch I took in.
Nico

I've seen stuff like that in a few of the images, they are quite interesting, to say the least...
Posted by: kenny Dec 21 2006, 05:27 PM
The "snow patch" is also surrounded by a greater density of boulders than seems to be the norm here. I was wondering if they are ejecta from a little crater which the snow patch occupies, a crater which has been deformed by the polygon-forming processes which dominate this landscpe

Thanks, Nico, and I'm glad you put "snow" in quotation marks.
At first glance, the light-toned material appears to be a substrate underlying the region, exposed by whatever process(es) formed that particular depression.
Posted by: tty Dec 21 2006, 08:57 PM
It looks like collapse feature of some kind. Perhaps the cryokarst version of a doline?

Thanks for the image, I'm another one who hasn't invested in a computer that will handle the JPEG2000 images and wouldn't be able to see anything in full detail if you and others weren't kind enough to send selected crops.
When I looked at the center of the white area in Photoshop, I found that it was totally saturated -- every pixel was totally white. Was there any detail visible using the wider dynamic range of the JPEG2000?
Thanks again, Steve
Posted by: tuvas Dec 21 2006, 10:41 PM
Any computer can handle JPEG 2000 images, the trick is to find a program that will allow it with any computer... Once we have HiView it'll be even better, so...

If you're using Windows just download Irfanview: http://www.irfanview.com/

I don't own a computer. I use our college system, which I share with several hundred staff and several thousand students. I am therefore not at liberty to download software when I choose. Nor can I download very large images or movies, though the systems people will do it for me if I make a special request as they have done for some MER panoramas, Mars and Titan movies and the Hayden Planetarium's excellent Orion Nebula in 3D movie. Websites that take more than a few seconds to open come up with 'access denied' and this includes NASA most of the time. I don't want to push my luck by asking for access to all the HiRISE images just now, so thank you once again Nix and the others who have posted cropped details (including the HiRISE team themselves for posting that detail of the natural arch). I just hope the system under development will work like the earlier 'zoomify' which was perfect for me.
About that patch of 'snow' - I wonder if there's enough to make a snowman? (Lightcolouredsubstrateman?)
Posted by: ustrax Dec 22 2006, 11:43 AM
A depression?

Posted by: ngunn Dec 22 2006, 12:01 PM
Nice perspective - just needs a tiny snowman waving to camera
- but it still looks like the white stuff is in a hollow (unless I'm seeing the whole thing backwards and those 'boulders' are actually small pits . . . )
Posted by: Sunspot Dec 22 2006, 12:02 PM
It's Frost.
Posted by: PDP8E Dec 22 2006, 06:23 PM
its something! Sun is at the left, looks like a depression
<sharpened, adjusted, tweaked, fooled around with...oh and an attempt at colorization>
|
Posted by: kenny Dec 22 2006, 11:09 PM
Nice attempt, but the colorization has the curious effect of making the boulders so much harder to see than in the monochrome verison...
Posted by: Gonzz Dec 23 2006, 05:22 AM
It's another beacon
Posted by: Gsnorgathon Dec 23 2006, 05:49 AM
I'm reminded of images of pit craters on Ganymede. Though my default assumption is frost, I can't help but wonder about Alex's suggestion of a substrate. Could there be a process that would leech volatiles from a shallow substrate? Maybe acting as a cold sink and encouraging frost deposition?
Posted by: Tman Dec 23 2006, 11:47 AM
No no, since it seems to be overexposed, it could be another bottomless (ice) hole like then Ultreya which was in contrast too dark for a final definition - so to speak it's (snow) white-little-Ultreya...
