Being as there is no data on winds at higher altitudes Mars, I was wondering if as on Earth the winds will be higher at altitude. Maybe we will get a few really good gusts for a cleaning event. I'd hope they know the direction of the prevailing winds. When we hit the peak and winter is over, meebee the rover can be situated to take advantage of the winds. I'd sure like to see the rover operate for a few more years.posted by john at 4:30 AM EDT | Discussion (3)
I am a long time lurker, and very occasional poster. I recently saw a documentary that contained a segment about life buried deep under the ground on Earth. The claim was that biological activity was very strong at 2 miles below the Earth's surface. The deeper you go under the Earth's surface, the warmer it gets. There is also an increase in pressure.
My question is does anyone here have information as to what the temperature might be on Mars as you descend miles beneath the ground. With the increase in pressure, and if there is a substantial increase in temperature, conditions would seem right for liquid water and life.

Really thought about posting this on the Geology section, but refrained from doing it since it's not going to be in any way an "experts" discussion (at least from my side).
I was browsing around in Google Mars and one thing I could notice is the heavy presence of straight lines running on the surface of the planet.
What caused them, from a geological pov?
Here's an example of three straight parallel lines. You can follow them for several miles, for example to the bottom-left where they separate a little and go on:
My first post here, but I've been reading quite a bit of what was posted over the years. Not a native so pardon any mistakes and non-fluency in what I write.
Also, my guess at the lines is that they were brought about by strong quakes, perhaps impact-induced ones.posted by galafon at 5:08 PM EDT | Discussion (8)
Just wondering how many people here are studying HiRise images. I finally bought a new puter and really spend a lot of time on those jpg2 images. What I have NOT noticed here is much interest in that mission. The images are FANTASTIC. I just have to learn how to crop them. There are archived images by the thousands that we can ponder while the government is shut down.posted by John at 1:30 AM EDT | Discussion (3)
Sol 410 raw images show upslope clouds. These were presented before but light and shadow on the distant hills have been problematic.
Descent data showed a saturated layer of, "ice haze." By definition, a visible accumulation of condensation on condensation nuclei nuclei is a cloud. Restriction of visibility is evident here.
Visible light scattering in association, or prism effect, shows violet reflection post to follow.

Can the prior measurements of methane from Earth be inconsistent with the rover equipment measurements, or is there a problem with the methods used in the Earth based techniques?
I created this topic to document my continuing examination of the Plastic (officially Schmutz_001) that was initially observed after the first scoop at Rocknest on Sol 61.
I do not believe it is Plastic. I believe it either came from the scoop and was dropped when it vibrated or it formed in situ.
Before they even knew what is was, the said:
"The rover team's assessment is that the bright object is something from the rover, not Martian material. It appears to be a shred of plastic material, likely benign, but it has not been definitively identified."
Take note of the language: "something," "appears to be," and, "likely."
Here's a translation to English:
"We took a look at it and we have no idea what it is, other than it is a bright object. It is definitely something, though. Although we don't know what it is, our best guess is that it is plastic because it kinda looks like plastic. We used to think it was a screw because it was little and silver like a screw. We can confidently and directly state for a fact with absolutely no qualifiers like "possible," "likely," or "appears to be," that it's NOT FROM MARS. We sure hope that its not something that will hurt the taxpayers' billion dollar machine and source of our jobs."
Here's the official explanation as to how it ended up there:
"Over the past two sols ... the team has assessed the object as likely to be some type of plastic wrapper material, such as a tube used around a wire, possibly having fallen onto the rover from ... descent stage during the landing."
Take note of the language: "likely to be," "such as," and, "possibly having."
What a most incredible journey for this half-an-inch-probably-weighs-as-much-as-a-feather piece of plastic. Either that epic journey happened or it simply came from the hole they dug the day they found it (or it was sitting there and they didn't see it on Sol 55).
When they first saw it on a Sol 61 Mastcam image, they thought it was a "possible screw." This was obviously proven to be incorrect when they got the Sol 62 ChemCam images. Then, they said it was a piece of plastic. It is clear that their examination was superficial as it was comprised solely of visual observation.
I processed this image in order to bring out the detail of the black "dust" around it:
I observe that the Plastic is quite tiny. According to NASA/JPL, it is "about half an inch long." It just so happens, just about everything else in the picture is equally as small:
Further, the rocks and dust surrounding the Plastic appear to share some of the same characteristics:
I also believe that the same features visible around the Plastic were observed on Sol 159 at Wernecke:
Interestingly, they decided not to zap it with the laser before they even knew what it was.
But they zapped the similar area at Wernecke:
They can be wrong. They were clearly wrong about the "possible screw." If they're wrong about it being plastic, too, then we're out of terrestrial things it could be, so we're left it is from Mars. What could it be then? Perhaps a "feature that may represent the effects of biological processes" (quote taken directly from the third of Curiosity's eight main scientific objectives)?posted by Wildcat at 1:03 PM EDT | Discussion (48)
I found this Blu-ray on Amazon called Tour of Mars 3D that has images taken of Mars from Curiosity, Spirit, Pathfinder, Opportunity, and Mars Reconnaissance Orbiter in 3D. I was thinking of buying it but I wanted to see if anyone else has seen it or has any thoughts or comments about it before I buy it.
Some interesting reading in there...
