As this problem has become a standard for many, but not all, currently, I am making a topic for following resolution of this. This has been posted on the 'Feedback' section of the forum.
All my posts but a few have 'disappeared' after either they were listed as various errors, or being successful, then becoming 'missing'. Promises for resolution have been made. Timing of saving these are time critical.
Thank you. The most recent is today, Oct. 16, 2012.

To study the process of eliminating some persons posts, but not all, posts, I am repeating the former post for a watch party. Feel free to do the same here. after my example. From 'Glenelg' topic, Oct. 16, 2012.

This link followed a longer entry with two images of Curiosity, MAHLI camera showing bright items up close.

Experiencing similar problems. I dump my post here. Can be removed when thought neccesaary by the admin / mod.

++++++++++++++++++++

I would like to ask you guys here if the "shiny plastic" object found by Curiosity could be blown there from the debris of the ckycrane.

Assuming that the picture of Curiosity, the backshell,the skycrane and parachute as can be seen here has North up and South down. Unfortunately there is no Wind Direction data here in the weather report for the first 19 sols. But it does suggest "
The pattern of pressure change across the sol is very similar from Sol to Sol. "

http://cab.inta-csic.es/rems/Doc%20Weekly%20Report/WR_report1_english_30092012.pdf

I know that the wind sensor is damaged, but they state:

"The wind sensor on the forward-facing mini-boom is unaffected. With just the one sensor, it makes it difficult to fully understand wind behaviour.

It degrades our ability to detect wind speed and direction when the wind is blowing from a particular direction, but we think we can work around that," said Curiosity's deputy project scientist, Ashwin Vasavada.

The example (?) weather report states: "Blowing from the East at 2m/s". It is hard to imagine that the plastic object was blown from the path the skycrane took (from curiosity landing,to skycrane impact) to the location the plastic object was found, when the wind direction was from the East. What I'm I doing wrong here?

My topic entry which appeared, then disappeared after a short presence also asked if the various items were from the separation of the back shell, as the MARDI images showed a view of the area East of the landing site, just above the MSL current traverse point, prior to the separation.
The swinging cone of approach angle viewpoint could cause a misdirection of reference view of a few hundred meters easily.
The only way we will ever know is to look closely at the objects.
Here is the closeup missing from the Glenelg posts. At 2X this shows an apparent conical cylinder and a tubular hollow shape with possibly two openings. Other MAHLI closeups are showing other shapes as well.
I can't distinguish whether the items are manufactured or natural, but my impression is natural Mars items.
Apparently this is a local test spot, not the bright tubular shape of larger size, broken in pieces. As such, a laser test of a larger item would give a chemistry check.

I had included warning that the dpi is higher, and some browsers may seem to lock up or the image might look blurry, if the settings are based upon pixel count, rather than the full size of the image in the file description.
The actual size at 2x is about 600x450 for proper viewing.
I didn't see this two items in subsequent photos. Were they buried? Were they Mars items?
.

.
These images show a brighter band of soil. Where was the soil band, and was it the injection fracture of the channel where one of the bright items was seen? In the channel the solid rock line was eroded severely, and appeared brighter than the soil/sand, but was more this color balance, and not at all the appearance of the dark rock line. Some chemistry effect changed the portion in the channel.
The bright items in these recent sols look very different from the plastic item. Perhaps they are giving us a hint of organic carbon readings in the area, with an Earthly marker for a carbon based product?

I am having no trouble today with posts.

Wow, those hot springs and microbial mats and other bright samples are impressive.

Barsoomer gave a Curiosity Cam video link, and I made a capture alteration of curious objects from Curiosity.

Our Curiosity just can't leave the scene.

How much pattern causes a social concensus?

Tried to view and post topic entries again on 'Exploration Of Gale Crater-part two' topic, October 24, and finding the same conditions of forbidden entry records after post #21.
I will present the entries here pending a correction or explanation.
...........

Absent a few days again. This is October 24, 2012, and I have been working with the late September issuance of the HiRISE image, ESP_028678_1755.
The image is now a 3D image, combined with ESP_028335_1755. As the two images have the rover shown in an early position, traverse only started, these seem a little dated.
The geology, and the best view of the rover body are seen in these to date taken from orbit, so, I am presenting a few variations of the scene in close ups, and one to show the massive flows from Mount Sharp slopes as dominate in the current rover position near Glenelg.
As unusual suggestive shapes are common in images at this area early in the rover travels, this gives a perspective of the source of the massive burials and erosion or other removal processes influencing the deposition and formation processes. A geologists assessment of the scene would have been appropriate for such a complex but massively altered area.
.
This is the HiRISE version at 1 to 1 size, as issued, for the rover Curiosity(MSL) position at about September, 2012. The images can be seen at the index page in color or greyscale, black and white being the best resolution usually. As with all images I issue on Image Shack host, you must click to enlarge the initial image to see the approximate full size, then use a right click context menu to 'Save Image As...', in order to get the largest and best resolution version. Sometimes the images are twice or greater in size from the viewed online largest viewable size. Using a 'Back' button takes you to the original smaller size, and in some browsers the viewable image was an additional tab or 'window' separate from the origin window or tab.
HiRISE MSL at 1 to 1. Near infrared 'red' source.
.

.
This is a 2 to 1 view I produced. Downloading this gives a best size view.
.

.
Below is a overview of the colored greyscale view of both original satellite views. It is altered and marked with three arrows showing a massive arc of a flow downslope or from the foot of Mount Sharp. The deep channel wall near Curiosity where Glenelg is located is at the darker grey mid-image swatch extending upward towards the rover.
Matching the large marked arc ridge, is several partial arcs inside the largest. The flows were not singular, therefore. The deep channel is distinctly a separate feature related along with the arc to a series of actions which would have deposited or altered the entire rover traverse and landing area. All items of the traverse closeups to late October would be related to the activity of the base or slopes of Mount Sharp.
Several interesting features, including a series of linear pits are found in the image near the rover landing spot.
To see all these details you may need to have red/blue 3D eyeglasses. Some details show even without the 3D optical illusion of depth.
.

.

Hopefully these posts will become available at the appropriate topic listings.

The geology of the landing zone is very complex and was massively changed many times. The origins of local small items could have been from Mount Sharp, the subsurface of the base margin now covered in dark large dunes, or, local as up welling or even deposited from directions not currently viewed.
A mystery for experts and instrument testing to resolve.

Posting the fully functional entry above at reply #9 here, with three images, on the 'Glenelg' topic, where it belonged, resulted in an editing 'removal' afterwards with a partial explanation that the image host had a coding error in recent updates, so, your copy to watch is here only now.
The information in the entry covers the positioning of the MSL rover, with the traverse path being at right angles to the fixed rover positioning. A second subject presented, related in the same original HiRISE image, is the massive downslope flows or upwelling mountain base erupting of flows, which inundate and bury the earlier MSL landing spot layers. The current view is of multiple episodes and issuance's of massive amounts of moving material, some probably hot or semi-fluid, possibly hydrothermal and water or ice influenced, other material possibly a cooler or dry detritus later partially removed from the pitted lower elevation portions of the proximity.

I will now present a continuation of the argument that the rover has a wheel orientation contradiction to resolve between ourselves and the NAS/JPL group, unless the explanation is currently available on this blog among knowledgeable persons.

.
Here is a view of the rover from the HiRISE source image ESP_028678_1755 at 8 to 1 enlargement of the HiRISE standard 1 to 1.
I have altered the original to allow direct viewing of the shadowed wheels on the near side, as they were slightly apparent in the smaller original in low contrast. The wheels clearly are positioned at the time of imaging perpendicular to the traverse path of travel, as appears in all prior imaging. The wheels have been visible in most images taken, and the rover is actually oriented in the long direction, despite all imaging manipulation such as compensation for foreshortening due to oblique taking angles, and the substantial blur of the satellite distance involved.
The appearance is that the rover is traversing while using the wheels in a 90 degree reorientation during travel, and rolling 'sideways' over the routine passage across Mars.
.

.
A non-marked version
.

.

Some explanation is required in this subject.
It is clear there is some potential for rotation of the rover wheels routinely available, but to issue a view at one orientation for still photos, and another during the long traverse, gives us camera viewpoints which would be unexpected.

This is an important subject, and it should not be 'removed' or censored any further at marsroverblog.com.

Explanations from any source?

The images altered in entry #10 shows two forward corner wheels beyond the deck margins, and a larger center oval shape which is the instrument multi-part arm, mounted on the front face of the rover.
The wheels are so small they are seen clearly in altered images only.


...........
A scheduled announcement and video presentation occurs tomorrow, Tuesday, for readers. Basic information about the traverse and mission should be up to date.

' NASA Oct. 30 Telecon About Mars Curiosity Progress - 10/26/2012
NASA will host a media teleconference at 11:30 a.m. PDT (2:30 p.m. EDT) on Tuesday, Oct. 30, to provide an update about the Curiosity rover's mission to Mars' Gale Crater.'
