You're wrong, they are not here.

Has anyone had any luck opening the files ending in .0xx in the Quick Look EDR folders? I didn't have any luck finding the Earth pics anywhere else but I'm sure they're buried somewhere in the EDRs.

I'm sorry Astroboy, but I'm wrong. I did not notice when PDS released Voyager's Quick Look EDR files. I'm writing a program that will view this data set. This is my first attempt to obtain the image IP_101.002 (still imperfect).

When I finish the program, I will download all volumes VGR_1201 - VGR_1247 and I will look through all the images.

Hmm. I had not noticed those, either. You can download them, change their extensions to raw, and open them in Photoshop with a width of 1280 and a height of 801. The couple of examples I've looked at so far don't look like cruise data, they look like encounter data, but according to the readme files there should be cruise data lurking in there somewhere.

^ I tried your method in ImageJ and it worked splendidly. Thanks Emily! The search is on!

Never thought I'd be the person to give this decade-old thread some sense of finality. I still can't find the Earth and Moon pics, but here, finally, is the complete set of raw family portrait images in chronological order:

The original files are 055560.023 through 0055590.010 in the QEDR volume VGR_1223.

Congratulations Astroboys. I suspected that the Pale Blue Dot family portrait can be found in the volume VGR_1223. Unfortunately, I was too tired yesterday to review it. You're the first. I am very pleased that this remarkable data set is not lost and will be forever in PDS.

Thanks! I'm having a lot of fun digging through the cruise data even though I don't have an automated way of doing so. This feels almost as good as the first time I found the raw encounter sets.

Hey guys! Not too long ago I stumbled across this interesting entry from the NASA Photojournal that shows not only the "Pale Blue Dot" image, but also a full narrow-angle ISS view of Venus; an equivalent "Pale Yellow Dot" image, if you will. A wide-angle ISS view of the general area used as a context is also featured in this Photojournal entry. Here's the full image of Venus by Voyager 1, cropped from the Photojournal entry:

This got me to realize the obvious - there must be the original photographs that make up the Voyager family portrait somewhere out there! However, I have been unable to find any of these original photographs from the searches I've made across the internet. From what I can make out from the "Family Portrait" image itself, there's at least 38 wide-angle ISS images and 6 narrow-angle images. I'd imagine the other 17 frames of the apparent 60 frames, as the title of the Photojournal entry boasts, are a combination of attempted narrow-angle shots of Mercury and Mars that failed, and wide-angle shots that weren't included.

So, I come to ask the big question - where can one find the original frames of the Voyager Family Portrait? Where can the original "Pale Brown Dot", "Pale Golden Dot", "Pale Aqua dot", and "Pale Azure dot" images be found? unsure.gif

the old voyager data is here
http://pds-imaging.jpl.nasa.gov/data/voyager/
but some of it is missing ( lost real to real tapes )

So see post #37 in this thread
http://www.unmannedspaceflight.com/index.p...st&p=184324


there are a few different types of file format for the old voyager 1 & 2 tv cameras

the old compressed PDS *.imq ( IMQ )
like in this example
http://pds-imaging.jpl.nasa.gov/data/vo1_v...o_1001/f122sxx/

the *.img / *.lbl normal PDS format
like in this example
http://pds-imaging.jpl.nasa.gov/data/voyag...ISS_0004/DIONE/

or the original tv images
http://pds-imaging.jpl.nasa.gov/data/voyag...TV/001010/DATA/
the tv images are in a odd format
8 bit 1280x801
CODE
gmic 063400.001.raw,uchar,1280,801 -o 063400.001.png




but they ? might ? be in "VGR_1223"
http://pds-imaging.jpl.nasa.gov/data/voyag...GR_1223/MAMQTV/

A few posts up I posted a link to all 60 raw images on imgur and the names of the directories the originals can be found in on PDS.
