That reminds me of the http://www.astro.uwo.ca/~jlandstr/plane … Cantaloupe Terrain on Triton
I wouldn't be surprised if they formed in a simular way.

*Very aptly named, I'd say. I'm not sure I've seen that image before; thanks for sharing it. Lovely...and that big X-shaped groove, nice.

All the things we of this generation are able to see thanks to our technologies, which astronomers of yesteryear would have given their right arm to see! How the heck can anyone possibly be bored??

We think of Mars as being an alien world, but it looks very Arizona-like.

Imagine a MER type robot on http://www.solarviews.com/eng/triton.htm]Triton. I think we would see a truly alien landscape.

Or how about a MER on IO?

http://photojournal.jpl.nasa.gov/jpeg/P … g]slumping of soil in the gullies opens cracks as it slips downhill, suggesting very "mud-like" behavior.
This must have happened some time ago, as the gullies can be seen covering up or cutting across many of these faults.

atomoid · 2004-07-17 04:36:34

Hmmm, yes, I suppose we're bound to employ Occam's Razor in explaining those streaks and, if dry avalanches are perfectly able to explain them, then that's where we'll have to leave it until better evidence becomes available.
Thanks, Atomoid!
:up:

here's http://photojournal.jpl.nasa.gov/catalog/PIA06453]a really striking image of some dust-devil-caused streaks.
As with the dust-avalanche slope-streaks, the dust gets disturbed making a bright/dark difference that is just unbelievable...

Shaun Barrett · 2004-07-17 07:52:40

Yes Atomoid, it's a nice picture of dust-devil streaks but Cindy beat you to it on this one over at "Devils and Dunes".
Not that it matters. It's good to see it again.

http://www.spaceref.com/news/viewsr.htm … 3415]South Polar Terrain

*Another great pic which looks like artwork. Layered carbon dioxide ice. Pic released today.

http://www.spaceref.com/news/viewsr.htm … 14]Troughs near Ascraeus Mons

*And some of the terrain looks SO smooth. Pic released yesterday. "...troughs and a pit, possibly formed by collapse, on the volcanic plains south of the large volcano, Ascraeus Mons. Wind-eroded debris mantles the scene and partly fills the depressions."

...and weird. Definitely one of the strangest pics of Mars I've ever seen.

"Scene from Ius."

Looks like big black fish swimming across an aquarium. :hm: Rorschach anyone?

http://www.spaceref.com/news/viewsr.htm … 638]Frosty Polar Slope

*Very nice contrast of light and dark, and also contrast of "textures". Just released pic from August 3. This is one of the most striking MOC pics I've yet seen.

remcook · 2004-08-12 12:43:16

the "interesting" one looks like some landscape upside down

*Fancy that.

http://www.space.com/imageoftheday/imag … rstatement!

*Yep, it's "a doozy" for sure. :laugh:

Reminds me of preparing cinnamon rolls. The dunes are the dough rolled up and the dots of unthawing are sprinkled cinnamon.

This pic surely has to rank as one of the all-time best. :up:

--Cindy

REB · 2004-08-27 08:20:59

That is a neat one. Has an almost geometrical look to it.

Palomar · 2004-08-27 09:01:35

*Hi Robert: Isn't it, though? Crazy corkscrews!

And you can see the spots (due to the unthawing process) down there on the ground BETWEEN the "rolls." I wonder how high the "rolls" themselves are.

Crazy! I want a poster of this. It should make National Geographic.

--Cindy

REB · 2004-08-27 11:09:39

It would be a great spot to send a MER...a very tough MER...with nuke power...and skis

Palomar · 2004-08-27 18:36:43

http://www.spaceref.com/news/viewsr.htm … ]Landslide in Sirenum

*Very cool pic. Half the slope (smack dab in the middle) is obliterated but can almost make out the obscurred terrain beneath. Must be very fine sand, no? In fact, looks like sand is blowing across the right central portion of the scene as the pic was taken.

And that curving trio of craters at the bottom of the pic, each one smaller than the next (Papa Crater, Mama Crater, Baby Crater) :laugh:

http://www.spaceref.com/news/viewsr.htm … 795]Should we rename Mars "Ripples" - ?

*It's simply riddled with ripples. Big ripples, wavy ripples, somewhat uniform ripples, broad ripples, narrow ripples, short ripples, long ripples...ripples on ripples. :laugh:

http://www.space.com/imageoftheday/imag … .html]Sand worms migrating north?

*Looks like they're having to dodge dust devils as they go. :;):

--Cindy

SpaceNut · 2004-09-01 12:14:49

It reminds me of stretch marks.. since there are slight depressions in the area.

REB · 2004-09-01 13:09:21

Sand Worms do not like water so maybe they are fleeing a wet area of Arrakis...I mean Mars

The Spice must flow

http://www.spaceref.com/news/viewsr.html?pid=13851]Wind streak changes

*Weird. Wind's been blowing from SE to NW. Looks more like a jagged shadow cast on the ground. 5-year time lapse.

--Cindy

Palomar · 2004-09-15 15:46:27

http://www.spaceref.com/news/viewsr.html?pid=13851]Wind streak changes
*Weird.

http://www.spaceref.com/news/viewsr.html?pid=13963]More wind streaks...

*So pointed.

Besides yardangs, these "critters" are becoming a fast fav.

Julius Caeser · 2004-09-16 12:22:34

It seems that mineral jerosite (hope its written correctly!) has been found in areas of Mariner valley..other pics suggest sedimentary deposits in other areas such as Holden crater,,,well..mapping the areas containing minerals that could be linked to a water story on Mars would give us an idea as to where the presumed lake or ocean was on the planet or locations as to where the water system if any,on Mars back in the Noachian period!Mars Express is doing a lot of progress as well as i expect that to be supported by the operation of Mars Reconnossance orbiter in 2 years time.Exciting times in the exploration of the RED planet!

*I hope Robert doesn't mind my posting this old Viking Orbiter 1 pic here. Didn't want to start a new thread just for it.

One of my favorite places on Mars

Palomar · 2004-09-22 14:28:32

http://www.spaceref.com/news/viewsr.htm … {{shiver}} Reminds me of a snake's skin!

*...and that portion of the song "The End", by The Doors ...ride the snake, to the lake -- the ancient lake; he's old, and his skin is cold... What a striking pic. :-\

http://www.spaceref.com/news/viewsr.htm … 017]THEMIS image Those perfectly round craters at cliff edges sets the pic off, IMO. Almost seems a "mirror image."
