How true, how true, Stu ! just when you think you're really drowning in all the terapixels of HiRISE alone, then you discover this site

Great, great stuff ... Can't stop surfing and discovering such treasures like this one:



( colorized MOC S1800492 )

Large Fresh Crater Near Marte Vallis (PSP_006985_2020):
http://hirise.lpl.arizona.edu/PSP_006985_2020

How did this form? Scrape-marks from a collapsing layer?

Looks like columnar jointing to me:

Jason is correct. Here's another example in Northern California, Devil's Postpile:

I saw the same thing here - http://en.wikipedia.org/wiki/Fingal's_Cave - it's astonishing stuff.

I wonder how that stuff survived the impact...

Anyway, another HiRise Pic:

Lizardskin texture near Mawrth vallis. Notice the the bright/dark pattern is inverted in the bottomhalf of the picture.

Impressive rock formation

Even the ripples have polygons.

New HiRISE Gallery now online...

Thanks GuyMac!!!!

Are you ready for hundreds or thousands new HIRISE's images ?
I'm ready. I love my blu-ray writer.

ORB_007000_008199 - many hundreds new images (2 June 2008)

Enjoy !

Wake up !

Good grief!!!!!!!!! Didn't see this yesterday... what a treasure trove! Thanks!

I have a headache caused by too large amounts of data.
HiRISE Experiment Data Records and Reduced Data Records
updated severeal days before oficial date (December 8, 2008) of data release #5.

Hundreds new beautiful images like this:

Well, that's my night off taken care of...!

Well, another PDS release is coming next week, so everyone should have even more fun.

Further to my post in the anaglyph thread here is a link to one of the images of the west rim of Endeavour:

Can't wait to get home after work to have a good look at it and run the terrain analysis.

New images officially released (1633 images).
http://hirise.lpl.arizona.edu/releases/dec_08.php
This release to the Planetary Data System covers orbit ranges 9300—10399 of the primary science phase.

Man, I'm in love with the anaglyphs!

This one's my favorite: http://www.uahirise.org/anaglyph/singula.p...PSP_001882_1920

That's a nice one Aggie! I've been looking through the new release and found a few "wow!" landscapes and features. Grab your 3D glasses Nick...!

Thank you Stu. That mesa above the fresh crater is by far my favorite.

....WHOA!!! Incredible!!! Blew Kay away as well, man, thanks!

Loved the plateau as well, but the larger crater is really something, too...it's deep. If I saw that thing on Earth, I'd think "sinkhole", not "crater"....

Glad you enjoyed them Nick!

I've just updated that post with a couple of new images, prior to submitting it to this week's "Carnival of Space", so you might like to take another look: the one of the gullies cutting through the ghost crater is quite stunning, I think...

New HIRISE release (08 Mar 2010). About 680 new images released (all images taken after recovery from glitch mode).

New avalanche image...

Wow! They're either more common than I thought, or MRO is getting very lucky these days!

Nice recent impact: http://hirise.lpl.arizona.edu/ESP_016299_2095

Wonder where all the rubble went? It's so smooth.

The rubble got ripped - Fifteen ways from Friday!
a buckshot impact, if ever I saw one
the lower pic shows the caboose!

EDIT: The upper pic ejecta rays are from the 'engine' - the only remnants of its crater!

They are actually very common in early northern spring, during which we shoot this area with CTX (and HiRISE, as we both monitor this area during northern spring, along with other northern polar scarps) basically every time we fly over it and there's generally always an avalanche in progress in every image. It's always exciting to see dynamic processes on Mars as they're happening!

That's pretty incredible. The 'Mars is dead' myth is down the drain!

Oh you're just making that up. If it were true you'd be posting the very best examples here

Not an avalanche but a rockfall that caught my eye...

You can almost hear the rocks cracking and clacking as they bounce down that cliff face, can't you..?

Edit: I just posted this on Twitter, and it got retweeted by Prof Brian Cox!

Ok. As an example, here are FIVE avalanches that were all observed in a single image (ESP_016265_2640):

And here's an example of what these things look like in CTX images (this is at 2x magnification):

Amazing! Thank you.

Freakin' gorgeous, is all, Stu. Wow!

Never thought I would ever see avalanches on another world caught in the act...and now they seem ubiquitous on Mars.

Three in one shot too!
Words fail me with this stuff; good thing we have a poet on here!
