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.

Splendid!

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?

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




but they ? might ? be in "VGR_1223"

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.

Carl Sagan reads ‘The Pale Blue Dot’:

Could you please identify the specific frame Earth & Venus appear in?

Comparing the collection to "Family Portrait of the Solar System" It should be this one .

Following post also gives time of image taken.

Edit: Here is the cataloged image with Earth an Venus.

I've been trying to open some of the EDR files from Voyager 2, circa 1985, from the period before the Uranus flyby, and all I'm getting are garbled frames (see example below).

I'm using the ImageJ RAW import facility, setting the frame size to 1200 x 801, which works for most EDR images——just not for a significant fraction of the archived data from both Voyagers prior to this point.

This is the main folder of images I'm trying to access:

https://pdsimage2.wr.usgs.gov/Missions/Voya.../qedr/VGR_1241/

Hopefully, someone here will have better luck getting these to display correctly!

Made some headway with this Voyager 1 image (labeled 1745S1-034 in the EDR file), but could well be a corrupted frame:

053380.003

Bizarrely, it doesn't seem to correspond with 1745S1-034 archived at the PDS:

https://opus.pds-rings.seti.org/opus/#/view...ss-1-s-c3395301

{Edit: it IS the same file; the overlapping framelets made it seem Titan was near the right ansa, which it isn't.}

isis3 opens up the imq and the img( linked above) files for that image just fine

the imq file is here

Thanks, John. However, I'm using this image as an example of an EDR file that doesn't open correctly. Of course, there are myriad images that don't have corresponding IMG or IMQ versions (such as the content of this directory: https://pdsimage2.wr.usgs.gov/Missions/Voya...R_1241/MBMQTV/). These are the EDR products I'm really interested in.

Hi Ian-

Have you let the PDS folks know about your problem?

John

John,

That's a good suggestion and a prudent course of action. I'll report back here when I get a reply.

Thanks!
