this is just stunningly beautiful. i'm making this one my desktop scene. i am totally geeking out on your mars photographs. they're pure mars porn.

^^looks like a lot of volcanic rocks strewn about. black porous clods, as if they were molten and had lots of air bubbles in them.

bonzelite · Jan 2, 2007

also, the Victoria cliff walls have areas with a distinctive look of being very smoothly eroded, ie, very, very old erosion.

Keep up the nice work in '07 - I really enjoy the images. This one was interesting. You can see the rover tracks heading to the crater. <img src="/images/icons/smile.gif" /> <div class="Discussion_UserSignature"> Don't let who you are keep you from becoming who you want to be! </div>

Hi there. More excellent images from rlb2. Keep churning them out. Any further to getting them published? Has the MER project team seen them?? Hi bonzelite, yes the Columbia Hills along with the floor of Gusev Crater are littered with volcanic rocks. The bubbles you noticed are called 'Vesicles'. rlb2's images show them very well indeed. I would like to know the source of this volcanic material. Did lava ooze up through cracks in the floor of Gusev Crater, covering up what was the original floor (a potential lake bed). Or is the lava related to the huge sheild volcano Apollonaris Patera, sitting to the north of Gusev Crater?? Are we any clearer to understanding what 'Home Plate' actually is yet? Hopefully Spirit will be able to pass to the north this time & view 'Home Plate' from the other direction. The MRO images taken with the HiRISE of the current locale of Spirit are intriguing. Home Plate looks flat & there is a strange feature to the south west, an impact crater or a small volcanic cone?? An interesting site indeed. I hope that Spirit can last long enough now to explore these features, although I fear the end may be coming close, seeing as 1,070 sols (980 sols past warranty) is coming up & there has been a dust storm, causing power problems!!

andrew, could the lava rocks have been ejected from very far away from their source? like in a catastrophic explosion?

Here is a very strange spire on Mars, which I found in a post on UMSF board by James Clavin, which was found within a very recent HiRISE picture release. From the shadow length, and knowledge of the pixel size, James estimated the height of this spire is estimated to be 44m (143 feet). So my question is: what formed this spire? Its aspect ratio (height/base) seems to be about 3, which is very steep. Among the causes of such steep spires I can think of: 1. volcanic cone - seems too steep for that. 2. volcanic pipe - the terrain around it has eroded away, leaving the more resistant central core. Maybe. 3. water erosion of a plateau, like the hoodoos of Bryce Canyon. Doesn't look like this though. 4. wind erosion of a plateau. Doesn't look like this though. 5. Remnant of an extinct undersea "smoker" vent, and the sea has dried up. (my idea, probably nutty) Any ideas? <div class="Discussion_UserSignature"> <div class="Discussion_UserSignature" align="center">- - - - - - - - - - - - - - - - - - - - - - </div><div class="Discussion_UserSignature" align="center">I really, really, really miss the "first unread post" function. </div> </div>

Do you know if the image has been vertically stretched? Most are. The image hasn't been approved yet, so I'm pre-asking here? Looking athe the original image (from the link, which hasn't gotten to the original original image), it looks like a volcanic (either magma or CO2/H2)) cone. I don't think "spire" is the right word. A spire is a "tall, acutely pointed" object. It looks more conic to me, and again we don't know how the image was manipulated. If you have a link to the original image, with information about the image processing I'd like to see it! <div class="Discussion_UserSignature"> But the Krell forgot one thing John. Monsters.

Here's a crop from the link provided of the cone/spire, adjusted slightly for contrast. <div class="Discussion_UserSignature"> Made weak by time and fate, but strong in will to strive, to seek, to find and not to yeild. - Tennyson </div>

The picture is from the HiRISE Becquerel crater image of Dec 6 (release 3), a bit 10:00PM position off center. No it isn't stretched vertically. <div class="Discussion_UserSignature"> <div class="Discussion_UserSignature" align="center">- - - - - - - - - - - - - - - - - - - - - - </div><div class="Discussion_UserSignature" align="center">I really, really, really miss the "first unread post" function. </div> </div>

Extraordinary photo. I would go for th eroded remnant myself on gut instict, but other possibilities can't be ruled out. I really like the brecciation of the bedrock, this is like ther fracturing we see at Meridiani. Maybe all Martian sediments look like this near the surface.

This is PROOF that Martians exist. This is ACTUALLY a LIFE SIZE replica of a Martian uh . . . private parts. (Which BTW, Martian Women are VERY UNIMPRESSED by Earth men.) . . . j/k btw <img src="/images/icons/smile.gif" />.

bonzelite- looks like a lot of volcanic rocks strewn about. black porous clods, as if they were molten and had lots of air bubbles in them. The key word here is "volcanic' that after MRO took another look at homeplate the rover team started salivacating over the thought of what they may have missed so they are going back for a closer look.... _____________________________________________________ abq_farside--Keep up the nice work in '07 - I really enjoy the images. Thanks everyone for your support. ______________________________________________________ Here is an image from MRO top left hand corner that I re-arranged the molecules to produce something that would look true color like.

Here are some larger parts from the above image. Note these aren't even to size; I had to reduce the size and the quality to fit within the 100,000k range. <div class="Discussion_UserSignature"> Ron Bennett </div>

Here is a very strange spire on Mars, which I found in a post on UMSF board by James Clavin Did it come from this section of the full resolution image I colorized below??? <div class="Discussion_UserSignature"> Ron Bennett </div>

The image 164841main_pia09097 is absolutely gob-smacking in detail. Many of the layers consist of cross-bedded sand and are capped by brecciated horizons that can only be old erosion surfaces. Waht's the scale? And where is the image from?

The image 164841main_pia09097 is absolutely gob-smacking in detail. Many of the layers consist of cross-bedded sand and are capped by brecciated horizons that can only be old erosion surfaces. Waht's the scale? And where is the image from? A lot of cross beddings, the image is from the North Polar region you can read the full caption and view the larger image here: http://www.nasa.gov/mission_pages/MRO/multimedia/pia09097.html shows the north polar layered deposits at top and darker materials at bottom, exposed in a scarp at the head of Chasma Boreale, a large canyon eroded into the layered deposits. The polar layered deposits appear red because of dust mixed within them, but are ice-rich as indicated by previous observations. Water ice in the layered deposits is probably responsible for the pattern of fractures seen near the top of the scarp. The darker material below the layered deposits may have been deposited as sand dunes, as indicated by the crossbedding (truncation of curved lines) seen near the middle of the scarp. It appears that brighter, ice-rich layers were deposited between the dark dunes in places. Exposures such as these are useful in understanding recent climate variations that are likely recorded in the polar layered deposits. Quite remarkable isn't it? I don't know what the scale is without doing some digging, the images above are from a image 4000 X 10119 lines and the original image is not to size, even the smaller cropped sections I couldn't fit it in on this thread. <div class="Discussion_UserSignature"> Ron Bennett </div>

Do lines = pixels? If so we could assume that 1 pixel = 30 cm as a rough guide. BTW, the thread title suggests MER images, but this is a MRO image. Do you want edit the title accordingly to avoid confusion?

rlb2 · Jan 4, 2007

Do you want edit the title accordingly to avoid confusion? Thanks done that as requested. Do lines = pixels? If so we could assume that 1 pixel = 30 cm as a rough guide. I am curios too; as soon as someone finds the correct scale for the above linked image please enlighten us. I don't know what the Pixel/ line thing would refer to so I can't give you a good approximation. I would think, like you referred to, lines would be 1 pixel wide... MRO altitude changes as it orbits Mars and so does the surface elevation as a result the scale would change depending on the instruments so the best way is to count on them in getting the scale per standard pixel etc. of each image recorded somewhere, for MRO I don't know where to look for the scale. In fact the scale would change minutely from the top of the canyon to the bottom of the canyon depending on elevation. MRO is in a lower orbit than the rest of the alien terrestrial spacecraft orbiting Mars. Someday we will have a GPS satellites system orbiting Mars so anyone at home (Earth) can tell its coordinates and elevation in real light delayed Martian time. The way things are going that will probably happen hundreds of years before we land any human on Mars..…. <div class="Discussion_UserSignature"> Ron Bennett </div>

do you want to edit the title? "Martian Girls in Pajamas Wrestling with nude Grizzly/Pizzly's" - that'll grab some attention, lol. My #1 question: can MRO snap rapid-fire pics of gullies during one pass? Think of the knowledge we could glean from a realtime image sequence of an outflow! <div class="Discussion_UserSignature"> I'm a recovering optimist - things could be better. </div>
