Yes, the trio of craters, with Endeavour at the north end, is clearly visible.

Here's another historic image:

It's a Mariner 9 image of Mars taken during approach. The planet is covered in a rover-killing dust storm (good job there were no rovers present at the time). Contrast enhancement has revealed the Valles Marineris full of dust. The south polar cap is visible as well as a few other features. Doesn't it look like Titan?

Yes, it does, especially in color. The image on the left is a true tri-color, the image on the right is only colorized.Click to view attachment

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
tedstryk
What did you use as your data source?
vk3ukf
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


tedstryk
I think they come from http://nssdc.gsfc.nasa.gov/imgcat/html/obj...ge/m04_01d.html
vk3ukf
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?

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?



jasedm
Not strictly reprocessing, more updating...
I recently stumbled across the familiar Voyager montage of Saturn and selected moons that was almost omnipresent in periodicals and textbooks in the early eighties (very nostalgic!)
Attached are the original, and my updated version using Cassini data.

I've been fooling around with some really convoluted stuff lately. Here is an image of Comet Tempel-1 I have been working on.

Also, here is Toutatis from Hubble (WFPC/1). You can make out that it is elongated and maybe two lobes, which is about what was described in the paper written about the observation. However, I have never seen a cosmetically "nice" version, which is why I fooled with it a bit.

Very nice... that's the kind of thing I was expecting to see on the BBC's coverage of Giotto's Halley's Comet fly-by in 1986, not that psychedelic, migraine-inducing... thing... they actually showed! I know now it was a false colour image, and very exciting scientifically, but at the time I was gutted, and very embarrassed by the "Is that IT?" reaction from my family, who I'd told to gather around the TV with me to see the "amazing" and "historic" pictures of Halley's Comet... rolleyes.gif
Phil Stooke
Fantastic, as usual, Ted. The Tempel 1 departure view leads me to wonder, do the earliest approach views look any different from the closeup images? Any visible rotation?

Phil

(PS I'm looking at Icarus...)
tedstryk
I would have to look more carefully...I am tempted to say yes, but it is easy to be fooled by spacecraft motion.
Stu
He'll be far too modest to plug it himself, so I'll point you all towards Ted's relaunched blog... http://planetimages.blogspot.com where you will find some truly stunning images. The "new views" of Ganymede are breathtaking - it's like watching images come in from a probe sent to an alien solar system, and seeing one of its worlds for the first time.

Go. Look. And shake your heads in wonder... smile.gif
tedstryk
I have added some updated versions of Galileo's global crescent views from 1997.

Hello
I send some mosaics from Mariner 9. And so it is uploading test smile.gif.
4th rock from the sun
Nice Mariner 9 images, really smooth. Good work.
tedstryk
Nice work!
machi
Thanks!

Now for something completely different from Mariner 9.

cbcnasa
Machi very excellent work smile.gif

Global mosaic from Mariner 9. Recent work.

How much enhanced/processed is that image? Because it looks so spectacularly unreal!
machi
I send one original image from Mariner 9 (mosaic is from three images), so you can compare original and result.
Images are improved so, that I'm trying preserve original usefull information and remove noise and reseau marks. Especially in widefield Mariner 9 images is problem with horizontal errors. Color is entirely artificial, just for better look.
ElkGroveDan
What is your source for the raw data? The one above looks much better than any scan of a print I've seen.
machi
My personal archive is converted from http://pds-imaging.jpl.nasa.gov/Admin/reso...m71.html#m71EDR by img2png (thanks to Bjorn Jonsson and PDS!) to png.
ElkGroveDan
I didn't realize that the data that old was available electronically. Good work. I wish I had the time to try some of that.
machi
I think that these images are oldest electronically available on internet.
john_s
I remember that mosaic well! I think it was on the cover of New Scientist at the time. It was the first ever full-disk (almost) image of another planet which showed dramatically more detail than a telescopic view, so it made a big impression on my 15-year-old self- it made Mars suddenly seem very real. It never looked this good back then though- nice restoration job!

No, the digital Mariner 6 and 7 images are available here:

machi
Fantastic! Thank you very much. I didn't know about this.
tedstryk
The Mariner 6-7 images on that site have a few issues, but they are pretty good. If I ever actually have time to work on an image again, I need to finish my Mariner 6 and 7 set. Here is my recent blog post related to this http://planetimages.blogspot.com/2009/09/m...ni-in-1969.html
machi
Another variant of Miranda mosaic.
tedstryk
Excellent work!
machi
Thanks!
Especially in this case, I have strong inspiration from your images. Your works based on Voyager 2 images are amazing!

I have many objections to this web page, image gallery is incomplete and unsystematic. For example, I can not understand why there no picture 6N01. Secondly, images 6N02 and 6N03 (for example) are at different stages of processing. Properly it should look like this, showing the successive stages of processing:

6N01

If they are presented only selected images, all images in the gallery should be on the same stage of processing. You can see how great the differences in the various stages of processing.

"New" images from Mariner 9.

That first image is great - one of the best images of Mars' limb that I have seen.
