The stubby nature of the part in the white box confuses me. <br />looks like an appendix. What type of process would form that? <div class="Discussion_UserSignature"> </div>

 

[JonClarke]

Groundwater sapping is one possibility. Groundwater sapping often produces short stubby valleys. Alternatively it might be a tributary truncated by erosion.<br /><br />Jon <div class="Discussion_UserSignature"> <p><em>Whether we become a multi-planet species with unlimited horizons, or are forever confined to Earth will be decided in the twenty-first century amid the vast plains, rugged canyons and lofty mountains of Mars</em>  Arthur Clarke</p> </div>

Blow up & enhancement of that 'appendage'.<br /><br />hope this helps.<br /><br />Nanedi Valles is certainly an interesting feature. Perhaps a future rover could go there???<br /><br />Andrew Brown. <div class="Discussion_UserSignature"> <p><font color="#000080">"I suddenly noticed an anomaly to the left of Io, just off the rim of that world.

Also I have enlarged & enhanced the centre of the Candor Chasma rock swirls image.<br /><br />I can see why portercc liked it.<br /><br />Andrew Brown. <div class="Discussion_UserSignature"> <p><font color="#000080">"I suddenly noticed an anomaly to the left of Io, just off the rim of that world.

You get sharper images for blowups if you click on the<br />link to the "full browse version" (and then enlarge the browse version) <br />instead of using the image as it first appears on the MRO image screen. <div class="Discussion_UserSignature"> </div>

HIRISE gives a lot of amazing views of the surface, but I can't find any data or comments related to SHARAD, the radar for detecting sub-surface water.<br />Does it work properly and what are the results ? <div class="Discussion_UserSignature"> </div>

 

[portercc]

Both locations would be a great place to send a an airship/lander/rover....how about a small version of an Osprey?

Thanks centsworth_II. <br /><br />I seem to have problems downloading large images. But once sorted I will do as you have suggested.<br /><br />Hi portercc.<br /><br />Yes I agree. I wonder if a serious study has or is being carried out along those lines??? <br /><br />Hi montmein69.<br /><br />I too have heard nothing about SHARAD. I have not found anything at all on the MRO website.<br /><br />Andrew Brown. <div class="Discussion_UserSignature"> <p><font color="#000080">"I suddenly noticed an anomaly to the left of Io, just off the rim of that world.

"I downloaded the 500 MB image of that region and the plug-in viewer you need"<br /><br />farside - I finally got the chance to "open" and check out the jpeg-2000 of candor chasma...a pretty interesting field of fractures at the top of the image.

 

[abq_farside]

How about posting a slice of it if possible, or just describe where you are looking. I would like to take a look at it but I am not sure exactly what part of the image you are talking about. <div class="Discussion_UserSignature"> <p> </p><p><em><font size="1" color="#000080">Don't let who you are keep you from becoming who you want to be!</font></em></p> </div>

Hi me too. portercc is pretty good at picking out interesting details.<br /><br />Here we are HiRISE realease: no 20.<br /><br />Three more potential landing sites for the MSL are included this week.<br /><br />Wednesday 4th April 2007.<br /><br />Andrew Brown.<br /> <div class="Discussion_UserSignature"> <p><font color="#000080">"I suddenly noticed an anomaly to the left of Io, just off the rim of that world.

<font color="yellow">"I seem to have problems downloading large images."</font><br /><br />You might have some luck here:<br />http://marsoweb.nas.nasa.gov/HiRISE/hirise_images/<br /><br />Great for looking at the images, but to download images I had to do a screen capture which I've never<br />done before. But I Googled and found instructions for doing screen captures to Photoshop Elements.<br /><br />Here's the tip of that stubby channel: <br />(the part in the yellow square will be enlarged in my next post) <div class="Discussion_UserSignature"> </div>

And here is the tip of the ripple field within the yellow square in the previous image: <div class="Discussion_UserSignature"> </div>

2 cents - great idea!<br />I'll copy area from large pic in the morning - CST

Thanks centsworth_II.<br /><br />The detail is just incredible. Your blowup must show details on the scale of less than a metre across per pixel.<br /><br />Andrew Brown. <div class="Discussion_UserSignature"> <p><font color="#000080">"I suddenly noticed an anomaly to the left of Io, just off the rim of that world.

<font color="yellow">"The detail is just incredible."</font><br /><br />And it could be better... for those with the computer power to <br />open the most detailed MRO picture files! After months of watching<br />Opportunity rove through the rippled plains of Meridiani and Spirit<br />meander through the Columbia Hills, it's possible to imagine what <br />a rover's eye view from the bottom of that channel would look like. <div class="Discussion_UserSignature"> </div>

Check out the HUGE image. That was my first impression, but I really don't believe those are dust devils.

[abq_farside]

I think you are right - after looking at the huge image and zooming in closer, they really don't appear to be dust devil tracks from this untrained eye. <div class="Discussion_UserSignature"> <p> </p><p><em><font size="1" color="#000080">Don't let who you are keep you from becoming who you want to be!</font></em></p> </div>

 

[MeteorWayne]

I think a trained eye will confirm they are clearly dust devil tracks.<br /><br />Here on earth there's not much of a difference in color between the surface and subsurface. That does not appear to be the case on Mars.<br /><br />What makes them not appear to be DD tracks to you? <br />(Actually, both of you) <div class="Discussion_UserSignature"> <p><font color="#000080"><em><font color="#000000">But the Krell forgot one thing John.
