Who Takes Care Of Mars Rover Blog and Why?

I guess most regular contributors have noticed that the Blog threads (topics) are not being advanced in the list when a new reply is posted. Other popular threads seem to have been moved far down the list. Are we being hacked? I E-mailed moderator Richard yesterday using the blog contact information, but haven't heard back. This is another attempt to find out what is wrong.

This blog has been very important to me at times but I've never tried to find out much about it. Is there really a forum moderator Richard? Hortonheardawho has sometimes had control over the inner workings here. Is Horton still involved? Should I E-mail Mark Carey? Why does Mark Carey keep this blog going? If anyone understands Mars Rover Blog and has answers to my questions, please help enlighten me. I fear this place might just disappear some day.

Mars Press Conferences

Tomorrow, streamed by

New results from MAVEN orbiter? From this, maybe:


I think Maven does NOT have a methane detector, so it's not that...

To be broadcast live on NASATV and streamed from

Illegitimate class structuring of posting limits

As usual, I have been blocked from posting relevamt images and text content on this blog. It is ten years and the same process.
My post;

This is the closeup at full image size, which initially confused me. It did not look like a tubular cell of mineral in formation, but rather a flat impression of a teardrop shaped object, with multiple cell walls and a 'tail' emerging into the air.
Completely desaturated of color here, it may not be a part of the mineral shapes, but isn't this just what we saw eleven years past at Eagle crater, in sections as 'rotini' patterned material?
How many items of a similar shape and pattern can be present on Mars with so few detected and identified minerals and chemical combination?
Mineral or organic, before the test results? Anyone brave and experienced?
Third white box from the left side toward the right.

The largest view of the full frame images other than downloading them, are obtained with the upper right corner expansion arrows, at the image host. Full size upon downloading, far right at 'share' area.

Attempted post to 'Active Mars' topic.

Mars Aerial Rover

Not sure if this would be a proper place to share our new project. But OpenRobotix Labs has been developing a Mars Aerial Rover since the fall of 2014. We are in Phase 1 of a Phase 3 initiative and need donors to continue forward. We would like for anyone interested in Mars research and exploration to view our project and donate if possible. Below is a link to the project overview. Feel free to submit comments.

Water on Mars

Nasa has found water on mars, they think that there might be living stuff on mars! Wow! One step closer to finding martians and other mars creatures. Evil or Very Mad

New Experiment

This is just a thought, im sure someone has thought of this.
Regarding life on Mars, has anyone thought to take up some organic matter....leaving it out in the open with a static camera, and seeing if it rots?
Surely that would provide proof positive?

Active Mars

I set out to start a topic where I could keep together all my posts about slope wasting and subsidence, particularly considered across all three rover sites, not just at Gale. Then I realized that a more natural division is a thread that discusses all current processes. My favourite indigenous soil disturbances are clearly very recent events, active during the rovers' travels. Examples of other "recent enough" processes that belong here in Active Mars are dust movements; the emplacement of sand, granules, pebbles, and cobbles in their present arrangements, including the formation and modification of all present ripples; the ongoing erosion of rock; and any other type of change for which a case can be made that it happened in the last few million years.

The sand slides have gotten to be a big topic. Sooner or later someone is going to put them all in a database with their individual characteristics for counting and comparison, but already for Gale alone there would be several hundred entries required, and more examples are pouring in every time we have a good look at a slope. Its overwhelming. Looking at just one recent sol, 1087, of the 150 large color mastcam images, 60 show evidence of slope activity. Its a very crude statistic, but it gives some idea how normal this is. Maybe I should post all 60 but I'll settle for a few. Here's three of the clearest:

So what are these disturbances? Let's take the most conservative interpretation and call them slip-faces, that is, avalanches caused by wind driven particle movements loading slopes with sand until they reach an over-steep condition and slide downhill. This process MUST be of interest to science. If Martian slip-face creation and wasting is basically the same process that we see on Terra's dunes, then there are a number of surprising differences to be explained:

1. On Mars slip-faces form on rocky slopes instead of on dunes.
2. On Mars sand slope wasting often takes place AFTER a surface crust has formed.
3. On Mars avalanches often originate from slope locations where loading with windblown sand from above appears very unlikely.
4. On Mars sand slope movements almost always occur immediately adjacent to rock or downslope from an origin adjacent to rock.
5. On Mars sand sometimes moves through very narrow rock fissures.

Its a longstanding mystery how the wind moves small particles on Mars. Here we seem to have a large body of evidence that must bear on that mystery, maybe evidence just as important as dune movements imaged from space. I still haven't found a single science publication that discusses slope wasting apparent in the rover libraries. If anyone has, please pass it on.

People on Mars ?

Ive been thinking. If there had been 'people' or humanoid life on Mars before, & they have since either left Mars or died off. Wouldn't there be evidence - ie Houses / machinery / other non-natural contraptions ?

We've been exploring Mars for a number of years now & havn't found anything remotely like this.

If a civilisation did live on Mars & had to evacuate. it would be improbable that they took / removed ALL signs of their civilisation.

Maybe Mars COULD have supported life - but did it ?

Handguns on Mars

I found two Curiosity photos that were taken consecutively that show two handguns laying on a rock. They are right off the edge of what I think is the left panel of Curiosity.

I would like to post the pictures but I don't see anyplace to upload to.

One is laying in plain sight with a good view. The other one is 18 inches to the left on the same rock ad about 1/3 covered with rubel.

Faces on "Missoula"

I pulled this picture straight from

Dead center, if you zoon in, there are two faces and what looks like an arm in a position as if holding up something.

Lakes on Pluto

I posted this in the space xploration thread, but Im not sure if anyone is looking at that. Just curious if anyone has noticed what to me look like lakes with ice flows on Pluto in this image

The usual gutless scientists say the troughs are filled with "some dark material" but to me it looks very much like liquid, maybe some kind of hydrocarbon or possibly liquid ammonia or nitrogen. There also appear to be brighter patches with clearly defined boundaries that look like they may fit together. Geometrically they look very much like an ice flow. Since they are white, they may actually be water ice, or some other ice, maybe CO2.

Either way looks really cool to me, any comments?

The largest lake on the right in the middle is sort of horseshoe or kidney shaped and has the most clear example of white ice flow looking material in it.

Heat Transfer Coefficient

Does anybody know the range of heat transfer coefficient (h) for Gale crater region ?
