I was just using that wonderful post by algorimancer of all the pia18920 and the cross eyed 3D technique.
The grooved terrain is crossing over and through some older large impacts.
So, those impacts pre-date the terrain grooving event.
I can only think it indicates a possibly solidification of a liquid mantle and it has expanded Ceres somewhat.

A very interesting pentagram shape for such a large impact structure.



What could the resulting boundaries of this impact indicate about the object it was formed on.

The overall shape of Ceres, the impactor, or both.

EDIT:
Well done algorimancer, while I was scrawling with an image editor, you had finished. I like the sand dollar association.
Agreed, it does look like a re-solidified melt, with a little aging showing.

The white splotch being visible as it has passed into the terminator could be a very high albedo material, such as snow, being illuminated by light reflected from the far wall of the crater that is poking up into the sunlight while the floor remains in shadow.

I see it as possible support for my iceberg impact proposition.
The second white patch may indicate a pile of snowy debris from the original impact due to the angle of the incoming projectile relative to the surface of Ceres.



It seems to be very over saturated in comparison with the rest of Ceres.

I have decided to make the dustbin lid my backup.

Does no-one like my Icy moon impact debris fragment impact proposition?

Just to be clear, a standard rocky body or iron fragment hits an icy moon, e.g. Europa, debris from the surface of Europa flies into space, possibly on it's first trip to the inner solar system, or possibly never traveling closer to the Sun than the vicinity of Ceres orbit, otherwise it would be evaporating, Ceres gets in the road, and splat, snowball in the ear for Ceres.

Now what else can I think of, there should be a measure of volatiles, a lot of methane still being given off, might suggest an icy moon impact debris fragment from the outer solar system that is recent.
Only water ice being found might suggest either, a Jovian icy moon source, but, do the Jovian moons have clathrate? That might hang around for quite a while at Ceres distance from the Sun.

Can anyone point any theories out to me for Grooved terrain formations like what seems to becoming visible and is also seen on Phobos?

Be almost funny if it was a chunk of Pluto that has recently hit Ceres.

Perhaps the white spot is where the Iron Chicken landed, if so, there could be Music Trees nearby. lol.

Hello folks, it has been a while since I poked my nose in for a blether.

Looking forward to a new release of Ceres approach images.

While pondering the white splotch, the thought of an icy moon debris fragment impact went through my mind.

Like a Europaberg impact.

A cryovolcano as previously head scratched would be nicer though I think.

Hi all,

this doc might help help those looking to decode the image file names a little bit.

It's regarding the sclk breakdown.

http://naif.jpl.nasa.gov/pub/naif/MSL/kernels/sclk/msl.tsc

I've been looking for the full MSL EDR SIS file name definition for ages.

I saw further back there, a fellow (rtphokie), piecing it together, thanks for what you've figured out so far.

The MER version,

<scid><inst><sclk><prod><site><pos><seq><eye><filt><who><ver><ext>

(above from, http://pds-imaging.jpl.nasa.gov/documentat...v4_9-25-07.pdf)

and this is a great straight forward page for the MER EDR SIS,

http://marsrover.nasa.gov/gallery/edr_filename_key.html.

For the Phoenix lander PHX EDR SIS, this the pdf to read,

http://pds-geosciences.wustl.edu/missions/...x/phxCamSis.pdf

MPF and Viking links escape me at the moment.
They were a bit odd by today's standards, short file names and part of the sclk string was the storage directories name.

If anyone knows if MSL EDR SIS is online somewhere yet, love to read it.

Any further pointers greatly appreciated.

Perhaps it will appear at the Analysts Notebook, early next year, hopefully before then.


Kevin. Werribee.

It's tougher than I thought Phil, this was the third going over of the same image.

I suspect you are corrct about the size, if it was maybe half to 3/4 of this, I'd be nearly dancing.

A white star shape on the surface.

First, so we can all see the target we are searching for up close.



Again, there is only a very slight possibility of it being Mars 3, but.

Object at,
6218x20834





This is actually the sort of thing I was first looking for, just found.

Hi,

I also have something that I would love to have explained in detail.

http://www.qsl.net/vk3ukf/Soho.html

You'll find a still image and a close up, several short videos from SOHO showing the anomaly.
The explanation was error correcting software?

This appears on several frames at different wavelengths.

Would love to know more about the optics, is there one CCD for the different wavelengths?

Hi Peter59,

nice images.

A 35mm film archive. Can these still be obtained?

Are they consisting of each image processed in several different ways?
Is this the original archive of all image data products from the spacecraft data?

PLEASE NOTE:

To any one that has previously downloaded the latest version of MERDAT. Released May 21, 2009

I had to replace the download, there was a bit of code not working, missing in fact.
There is now MERDAT X+ Beta 1.0.1

The save function in X-Eye now works, save function on main page has also been tidied up

Analglyph creation works with GIFs.

Filename conventions on Viking and MPF colour pics made better.

If you downloaded it recently, please discard the copy you have and get it again.
There is a big difference.

If you download MERDAT X+ please use the MERDAT users group to post any error or bug notices, While using the program, click on Help then Email.

Merdat X+ 1.0.1

Sorry about that.

Kevin.

Hi jekbradbury, thanks for saying hi, I believe you too.

I want to try and wrangle some FITs py code into a Delphi GUI.

Hi, I recently discovered python,

I was wondering if anyone here dapples in the same?

It's just in case I get stuck, I'll know I have somewhere to look to, while I scratch my head.

Yes, that's the d version alright, the h version looks like a top end stretch of the numbers, a variation of 1 in brightness stretched in that area.

I recently found python code, had a go and made a XP gui for Bill Allen's PDS *.img file display, save and header scripts.
I found that manipulating images in python is easier than using delphi 7, but I still need delphi for the gui.

I liked the LIDAR imaging, if you played those in a movie, is it like a waterfall display, such as I have seen on some audio and HAM software.

Edit: thanks for the URL, I updated the references.

So what did I make?, is it a good mix or a bit of a furphy?

Could the grooves on Phobos be fracture marks from actually being shattered by the Stickney impact but only gently moving apart a little only to meld back together?

The sources were all from the net from various places, I was trying to find all the Mariner 4 frames, which I eventually all found on a NASA cd somewhere, but prior to that, there were a few versions of the same image at various websites on my PC, I didn't know which was the original until I went to NASA and got the lot. Anyway, the other versions, perhaps one from one of your own sites, if you have done this before, were different contrast levels, one was bw way stretched, to see the max extent of the atmosphere.
The filenames weren't changed much, MA4-01e.gif become MA4-01d.gif on another example and a MA4-01h.gif as well.
So I played around with making different bands from the one image, using the contrast levels to separate them.
I used a mix of the different contrast versions from various paces on the web, I'm sorry, I can't remember from where, and the original image MA4-01e.gif from NASA.

edit:
I had a look around the hd and found,

The original NASA filename is Ma4-01E.gif
The high contrast version is m04_01h.gif, it's a bit different. ? a replaced with 0.
Did a google search for m04_01h.gif

Found it and m04_01d.gif at

http://library.thinkquest.org/19455/marine...age_gallery.htm

and looking at it, I have no idea how they got that from the original.
There isn't any detail about how the images were made.

Perhaps the person that made it, did it from a print out of the original numbers.

Do those files of the numbers for the images exist anywhere accessible to the public.
It would be like having a RAW file.

All I had to play with is the NASA gif and what I found elsewhere.

I found another image the same as m04_01d.gif
It is named nssdc_MR_Mrnr_m04_01d.gif

Well, whomever did the job on those numbers did it pretty good, (drool)

Google could not find a nssdc_MR_Mrnr_m04_01d.gif nor a nssdc_MR_Mrnr_m04_01h.gif

I have no idea where nssdc_MR_Mrnr_m04_01d.gif came from. But it is the same image as m04_01d.gif from thinkquest.

I'll try and reproduce what I did.



Edit again:
I put all the images I found on the same page as the colour pic.
http://www.vk3ukf.com/Mars/Mariner/Mariner...one_page_01.htm

Hi tty, thanks for the name on the Japanese rocket plane, it escaped me at the time, certainly an interesting bit of history. I would love to have seen to look on the pilots of those things when they took them up for the first time, or nearby witnesses of one leaping into the sky with a roar.

Love the pic of the guy with the crayons, I found some others of this just recently.

http://gizmodo.com/5266151

They include a close up of the sheet so you can see the numbers.

Hi, thanks for these pics, love them.

I had to have a go at an oldie myself.
I know its been done before.

What do you think?



False colour Mariner 4 image

Removed full in line quote of previous post - Mod

Well, here's the little models I raked up, after reading this.

Love the spiders.

There is an old 1920's Buck Rodgers spaceship.
The little Viking Lander, Lunar Prospector, Saturn V, Voyager, Sojourner Rover and Japanese version of the Me 163 rocket plane, came in little Kinder Surprise type things from Japan.

The little alien is a rubber stamp, it lights up red when you press it down on paper and it makes its mark.

The Thunderbirds have a tiny hidden button that activates a voice chip, each plays 3 random typical lines from a show.

Thunderbirds are go, etc.

The crystal cubes have in them, a MER, Soyuz, ISS and MIR.

The Iron at the back, I picked up in the hills to the south west of the Henbury meteorite craters, in the Northern Territory.

Hmm, can I go silly, why not, It was said that early in our systems history, the Earth was maybe hit by a large object and the debris formed the Moon. Perhaps Deimos and Phobos are hunks of Mars itself blasted into orbit by such collision in the early system of rogue objects that were eventually ejected or destroyed and partially absorbed. Maybe Mars could be surrounded by hunks of Earth, blasted into space by the collision that created the Moon. The grooves on Phobos could be, rock layers from a larger original planetary sized body. It's not hard to imagine a few fish, whales, trees and other unexpected things to be in space. Earth has been hit very hard a few times since life has been on it, to blast such material into space. There are bits of everything everywhere. I like to collect meteorites, can you tell?

Isn't it weird how so many objects have these one face toward the planet orbits.

Why do some moons rotate in relation to their parent body and others not, is this a clue to their formation?

There is probably some lumps of stuff ejected from other star systems floating around in ours somewhere, hope a little bits lands, or someone finds a bit that already has.

:-)

Hi Phil, I didn't say it could be the lander, I was looking for the lander, I mentioned it may be the aeroshell, and also, yes I was looking for a four leaf doovalacki/star shaped object, have a guess at how many little splat marks I magnified for a better look, hundreds. It was also pointed out to me elsewhere, and I should have realized myself, about the dust storm at the time, the chute and backshell, may be further away than I thought, out of frame, need more pics of this area.

The shadow appears cone shaped, I don't know if it is due to the shape of the object or sun angle.

Curious though, is 1.2m the diameter of capsule in petals folded or petals unfolded position? If 1.2m is folded, It's apparent diameter could nearly double in the unfolded position.
Although I think it would still be a lot smaller than any aeroshell or heat shield that helped get it there.

I think the Mars 3 lander must have opened its petals, otherwise it would not have attempted an image and sent it home.

I don't recall seeing folded and unfolded diameters mentioned anywhere, it would help.
I was thinking of making a little paper cut out model of Mars 3 lander, taking a pic, and reducing the resolution, to see what a four leaf lander like Luna 9 / Mars 3 looks like at hirise res. Image res was 25cm per pixel. I have a model of a viking lander, I'll use that to scale a Mars 3 paper cutout, then do a pic from overhead while they sit on some dirt. But have to find out the unfolded diameter to scale it.

Probably is a rock, but you have to show others and say, what's this?

I saw nothing else of note on that image, yes I will keep looking, plenty of MPL search pics to keep me occupied for a while. :-)

Hi, I spent a couple of days going over one of the HiRise images posted for lost spacecraft searches. ( I did it twice ).

Soviet Mars 3 lander search area.
http://hirise.lpl.arizona.edu/PSP_006154_1345

When searching for manmade lost bits on the surface, you MUST use the full resolution image, you will see nothing if you use a browse image.

I use the IAS viewer at 1:1 resolution.

Anyway, near the top left, at pixels, 5215x2965,

http://www.vk3ukf.com/Mars3PSP_006154_1345-001.jpg



I did send an email to the HiRise blog folks, and to the Planetary Society, I only did this yesterday, so have not heard anything back yet.

It is either a nice aeroshell, or a big round shiny rock.
Nothing else of interest was spotted in the image, there is only one image out of the entire landing ellipse, if it is an aeroshell, the other bits may be nearby out of frame.

It takes me about 6 to 8 hours to check each full resolution image, I have only looked at a couple of full size images, the others were in the MPL area, nothing spotted over there yet, so far.

Why does this stand out to me apart from some of the other bright spots on the image, this is the only one that has no blocky appearance, and I can see the back of it that is in shadow.

Any thoughts on this?

Kevin, VK3UKF.

Hi folks, I have been playing with the software code again, discovered Python a month or so ago.

I have updated the MER software that works with standard filetypes, bmp, jpg, gif etc, to also work with Phoenix, MPF and Viking.
It is for deciphering the data in the filenames. It can give dates and filters etc.

The new name for MERDAT is MERDATX+

The reasoning behind MERDAT software is to make it easy to get at dates and filters using standard image filetypes, without having to open PDS headers. It can also create colour images, avi's and stamp images with selected data, spacecraft name, date.

I also made a PDS *.IMG file viewer, called Sojourner Viewer 1. which decodes MER, Phoenix, MPF, Stardust *.IMG files.

This is based on Bill Allen's Bippy PDS module.

Sojourner Viewer 1 is for browsing directories and showing the images as you browse, this avoids having to click file open every time an image is to be viewed. Sojourner Viewer 1 is specifically designed for Sojourner, but, it will work with files and display images for the other spacecraft mentioned, it will save *.IMG data as BMP, JPG, RAW and TIF. (edit: and GIF)

I will still be updating these but as some may have noticed, it is a long time between updates.

I want to add a few things to each, SJV1 will have a function added that will convert an entire directory of IMG files into whatever you want, for movie making purposes, and I want to expand its *.img file capabilities and add FITs.

I have a lot to learn yet.

These tools are probably a good place to start before leaping into ImageJ, GIMP and NASAVIEW.
Oh yes, ImageJ is the only one I have found so far that will open RAW files.

Have a look, there are some screen shots and info on the download pages at,

http://www.vk3ukf.com/index2.htm

Comments and suggestions, always welcome.

All the best.

Kevin, VK3KUF.
