Unmanned Spaceflight.com _ Voyager and Pioneer _ Voyager 1 images of Earth

Posted by: um3k Jun 15 2006, 02:12 PM

I know for a fact that Voyager 1 took at least one picture of Earth. Does anyone have any idea where raw data can be found? Or any data at all, for that matter? The only online image I can find is this one: http://photojournal.jpl.nasa.gov/catalog/PIA00013

Posted by: ljk4-1 Jun 15 2006, 09:27 PM

You mean besides this one:

Yeah, I already know about that one. I'm looking for much closer ones.

Posted by: tedstryk Jun 16 2006, 04:03 AM

I don't know if closer ones exist. I have searched for the raw data for the earth moon shot, but haven't found it.

I did the same - strangely the Voyager data sets dont start "0001" they start "0006" - and I'm guessing the first 5 are infact calib, checkout, and the images we're talking about.

I'm pretty sure I've seen closer images somewhere, but where, well, I have no idea. Then again, maybe I'm just confused. I know Mariner 10 took closeup images of Earth, maybe that's what I saw. But still...

*In case I implied otherwise, I'm also looking for Voyager 2 images of Earth.

Posted by: PhilCo126 Jun 16 2006, 02:48 PM

Did the GALILEO spacecraft take such an image as well?

Posted by: djellison Jun 16 2006, 03:06 PM

Just a few smile.gif

Galileo took far more image data during its Earth flybys than it was able to return from Jupiter.

Posted by: deglr6328 Jun 17 2006, 08:10 AM

And some of the most interesting images of earth from deep space probes contain almost no detail of the planet at all.... (imho) smile.gif

This is the problem with the older missions, there is not so much online but in real libraries etc. I am still loocking for Voyager press kits and other documents online, but not much luck so far.

I am sure the raws of the famous Earth-Moon shot are at some place, they have to be. The Earth-Moon pictures were only made by Voyager 1 (launched second), the reference for this is an old issue of National Geographic (1990) from the Neptune encounter. The idea to take a picture with both bodies came after the launch of Voyager 2, Ed Stone said there. Maybe there are shots from greater distance (optical navigation or check out) from both probes, but a far as I know close ups exist only made by Voyager 1.

A great source for Voyager pictures is:

http://pds-rings.seti.org/catalog/vgriss.html

But there is nothing you are looking for.

Btw. deglr6328: What does this picture show and which craft made it?

Posted by: djellison Jun 17 2006, 07:10 PM

I think it's the Galileo laser-comms experiment.

Hey, I can see my house!

Did you remove the sunbeam purposely? Or did it just disappear when you enhanced it?

Your image certainly brings home the Pale Blue Dot theme.

At the distance Voyager 1 was from Earth in 1990, what would our planet's relative
magnitude be?

I just kept tinkering until I was able to make the 'background' around earth nice and dark -- then I tried to bring out a bit of the pale blue that was imaged by Voyager.

I would hate to try and guess what the earth's magnitude would be if one was riding 'on board' Voyager -- I would think right around 0.0 [neither negative nor positive] but I will leave this to someone more versed in the relative brightness of celestial objects.

Posted by: PhilCo126 May 6 2007, 02:14 PM

So it was Voyager 1 which turned its camera back to the planets and took the 60 photo mosaic ( 39 wide-angle and 21 narrow-angle images ) photo now known as the 'Family portrait of the solar system' ... Pale Blue dot press meeting of June 1990.

That's so clear I'm surprised the moon isn't visible as well.

Posted by: As old as Voyager May 7 2007, 03:54 PM

Here's a link to JPL's Solar System Simulator that shows the location of the Moon as seen by Voyager 1 on the day it took the 'Pale Blue Dot' image.

http://space.jpl.nasa.gov/cgi-bin/wspace?tbody=301&vbody=-31&month=2&day=14&year=1990&hour=00&minute=00&fovmul=1&rfov=0.01&bfov=30&porbs=1&showsc=1

It brings home just how unresolvable the Moon would appear on the image!

Posted by: Jyril May 7 2007, 07:17 PM

Hardly surprising, as the Moon is far smaller and far darker than our planet.

BTW, the crescent view of the Earth and the Moon is the first of its kind.

Half Venus has a magnitude of -4 from about 1 AU. Earth is about 1/4 the brightness of Venus. When Voyager was about 30 AU out, it would be 1/900 dimmer still. 1/3600 of Venus's brightness is 9 magnitudes dimmer, so a half Earth as seen from Voyager (Neptune) would be about a +5 magnitude object. A lot brighter than Neptune is, seen from Earth, since Earth is so much closer to a light source.

Interestingly, that means the planets "visible" to the human eye from Neptune would include Venus, Earth, Jupiter, and Saturn... probably not Uranus, which would show a crescent except when it was very far away.

I can't find these raw images at PDS. Family portrait of the Solar system was taken by Voyager 1 on February 14, 1990. I found http://pds-imaging.jpl.nasa.gov/Admin/resources/cd_voyager.html last image taken by Voyager 2 on September 29, 1989. I hope that they are not lost.

Posted by: Deeman Aug 25 2008, 04:35 PM

Hi there,

Found that one in my Archives .To be honest, I dont know whether its Voyager I or II .Shame on me ! sad.gif


Dirk,





Posted by: elakdawalla Aug 25 2008, 05:48 PM

It's Voyager 1, captured on September 18, 1977.

I just checked with a friend at the Rings Node and he said that since neither the 1977 or 1990 images were part of an "encounter," they weren't part of the archiving process that sent data to the PDS. However, he expressed confidence that the data was lying around JPL somewhere, and said he'd check into it.

Posted by: Ken90000 Aug 25 2008, 07:44 PM

That is exciting news. I would love to see the dataset that included those post-launch Earth and Moon shots. Likewise, I believe Voyager imaged Mars as it crossed it’s orbit. That would be a fun group of images to see as well.

Posted by: tasp Aug 25 2008, 10:46 PM

Has anyone ever seen an image of the flat white optical calibration plate ?

I realize the picture would be a white blob, but we had a thread a while back about probes that had photographed themselves. As bad as that Voyager image would be, detail wise, it still counts.

smile.gif



Posted by: PhilCo126 Aug 26 2008, 10:03 AM

I have a large collection of Voyager Press Kits, so I guess I'll have to make these available in .pdf as soon as possible ;-)
What I'm also interested in are the videos produced by KCET Public Television network which ran a nightly "Jupiter Watch" show during the months February and March 1979... about time someone put those on YouTube !

You can find images of the optical calibration plate at the PDS as well. There are some examples on nearly all of the volumes. They are labeled “CALIBRATION PLAQUE”.

Remember, even the wide angle camera had a relativity narrow field of view. Therefore, the image only includes a small part of the plaque. The imaged just look like a flat white field with a few imperfections caused by the camera itself.

Dear JPL data archivists,

Can we please see the raw images of the Pale Blue Dot now?
Its been 22 years! blink.gif

Both my daughters (one finishing college and one about to go) were both born after 1990!
..and the computers we have now have speeds greater than 16Mhz, and with memory space greater than 32Meg <really!>

<well...except for my still running 1974 DEC PDP8 with a blazing clock speed of 1.2Mhz and 24KILO-bytes of core memory....>

Posted by: machi May 11 2012, 10:01 AM

"Can we please see the raw images of the Pale Blue Dot now?"

That would be nice.
BTW, some images from beginning of mission are unavailable too. For example famous images of Earth and Moon.

It wasn't and still I don't see it in archive. Two known sets of images are missing in archive. 1990's well known "Family portrait" and 1977's images of the Earth and Moon.
And of course, it's possible that there are some other, generally unknown images.
I think, that is good idea to digitally archive all older NASA's data and make them online, because classic magnetic tapes or even papers are not very safe. For some older data, even people from NASA archives don't know, where they are.
For example, original digital raw images from Mariner 4, or digital raw data from Pioneer 10 and 11 imaging photopolarimeters.

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.

Posted by: elakdawalla Apr 20 2016, 08:53 PM

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.

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.

Posted by: PhilipTerryGraham Feb 16 2017, 02:36 PM

Hey guys! Not too long ago I stumbled across http://photojournal.jpl.nasa.gov/catalog/PIA00450 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 http://photojournal.jpl.nasa.gov/catalog/PIA00451, 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

but some of it is missing ( lost real to real tapes )

So see post #37 in this thread
http://www.unmannedspaceflight.com/index.php?s=&showtopic=2857&view=findpost&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_vo2-m-vis-2-edr-v2.0/vo_1001/f122sxx/

the *.img / *.lbl normal PDS format
like in this example
http://pds-imaging.jpl.nasa.gov/data/voyager/VGISS_0004/DIONE/

or the original tv images
http://pds-imaging.jpl.nasa.gov/data/voyager/edr/VGR_1201/MAMQTV/001010/DATA/
the tv images are in a odd format
