What a boring hosting site... :rant:
I'll try to fix them.
I suppose they are these:

anim-river.gif
anim-river3.gif
anim-trench-73-maxi.gif
cycle1.gif
endurance2-part.gif
endurance-81-93-part.gif
fake-mars-by-NASA.gif
hills-anim-8-88.gif
hills-zoom-1.gif
hills-zoom-2.gif

The others SHOULD work fine, I don't see anything strange in their file-attributes.  :hm:

Thanks for the feedback.

#31 Re: Unmanned probes » Columbia approaching animation - Color and b/w » 2004-05-15 07:12:25

A new couple of animations: currently they cover Sol 106-129 and Sol 106-123 periods, but maybe I'll update them without changing the filename, so they'll cover different periods if you read this post after 15th may, 2004:

#32 Re: Unmanned probes » Nasa hoax: why?!? » 2004-05-15 03:51:14

Ok, guys, let's summurize results:
Combining replies from this forum and from http://www.badastronomy.com/phpBB/viewt … 64]another forum, and also looking at http://marsrovers.jpl.nasa.gov/gallery/ … 2.jpg]this image and http://www.lyle.org/mars/imagery/1P1371 … .html]this image, it is now clear that:
- NASA deletes original sky from rovers' photos becuase it is not good to see (image 1)
- The image below has not been retouched, it's just the rover camera failure
fake-mars-by-NASA-t.gif
(See extreme example in the second image linked).

So, in the first case, no "hoax", just "embellishment"  roll , in the second case no "Hoax", just "failure".

And... yes, we are the same person...  tongue

#33 Re: Unmanned probes » Nasa hoax: why?!? » 2004-05-13 11:12:01

That is due to the exposure setting of the shot where the (relastively) bright sky causes the CCD element to "bleed over" vertically into neighborhood CCD elements/pixels.

[...]
(http://www.lyle.org/mars/imagery/1P137167255ESF2019P2566L7M1.JPG.html]heres an extreme example),
[...]

What is really strange is the edge between saturated pixels and not-saturated pixels: no shade, just an exact edge-line! Maybe the onboard SW automagically cut away any "wrong pixel", replacing it with a white pixel? I wonder what kind of algorithm can decide when a pixel is "wrong"... smile

So that must be whats going on. I dont think NASA has any motive to doctor the images like this.

The "extreme example" you linked appears to be quite clarifying . But it's quite... "funny" that a 400,000,000$ machine takes such awful images... :rant:

Gee whiz, I wouldnt have expected such *glaring* limitations with the ccd. This pretty much constitutes a good case-study of the limitations of the dynamic range of these ccd sensors and how much compromised the data is from these sensors due to this effect (as well as compression artifacts among other things (im waiting for the day when they can make a ccd with infinite dynamic range by merely doing photon counts)). I thought we could do much better than this with 21st century technology but i guess not, these are probably the best sensors we have for all the extreme conditions the MERs need to address...

As I already stated in other forums, I really think next rovers should carry a commercial 300$ digital camera to take simple "true-color" snapshots using just ONE ccd for ALL colors... Let's reserve multiple CCD camera for multispectral rocks examinations....

Maybe you don't remember the first posts of this thread, showing evident image retouoch made by NASA...:

From RAW images:
detail-mio.jpg

From NASA:
detail-NASA.jpg


What I don't understand is why NASA "doesn't like" natural martian sky!
Are there Green Men greeting Opportunity, in the Martian sky?
Is there some unhappy employee at NASA which would like to discredit NASA?
Did somebody at NASA let a coffe cup fall on the PC, so image data were corrupted, so he had to manually repaint the image?...
Was there a searchlight visible in those photos, as the picture was taken at Universal Studios?...

Guys, I really don't know what to think, but those images are clearly retouched, this is a fact. About the reason, I don't know, I'm not an international detective...

Luca

#35 Re: Unmanned probes » Nasa hoax: why?!? » 2004-05-11 13:02:55

I am definitely disgusted by NASA public images policy:
fake-mars-by-NASA-t.gif
http://jumpjack.altervista.org/immagini … A.gif]zoom

I didn't do anything to the original images (1P137165596ESF2019P2357L7M1.JPG and surounding, from http://qt.exploratorium.edu/mars/opport … atorium),I just put them into a ping-pong sequence.

#36 Re: Unmanned probes » Forum is dying? » 2004-05-11 10:59:14

This forum is dying, passing to a http://www.badastronomy.com/phpBB/viewf … ?f=12]more populated one...  sad

Luca

Very disappointed in you saying that Luca, after you were given such tremendous personal support recently. I frequent BadAstronomy's "Martian Chronicles" forum too, and yes there's some very good discussion on there, but - with no disrespect meant to that forum - I don't think "more populated" equals "better".

Just because your postings don't generate dozens of replies

I don't want replies, I just would like to read something new in this forum... ???


doesn't mean it's "dying" - maybe it just means that people are content to read and learn,

You lurkers... :;):
Anyway, I'm going to actually build my own web page with links to all animations/images I posted here, and I'll continue posting them there rather than here.
If you want to see further images from me, you will have to keep alive this forum... tongue  Else I'll understand that "No life on Mars" is, unfortunately, right. ???

Luca

#37 Re: Unmanned probes » Forum is dying? » 2004-05-11 09:41:19

I think you right cassioli. To prevent forum of dying you need to post  minimum 10 animations and 25 pics of blue mars per day. :band:
I think that is normal that people after 3-4 months of intenisive debate take a rest.

Indeed, it's going to become my own blog about Mars...  ??? Maybe I should add a counter here, to know how mane people is visiting  "my site about Spirit and Opportunity".
Mmmmh... maybe I could start posting some banners...  tongue

Luca

#38 Re: Unmanned probes » Forum is dying? » 2004-05-11 09:38:20

*Well, you're entitled to your opinion of course.  smile 

But why start -this- thread in the "Unmanned Probes" folder?  A bit out of context, don't you think?  There's always the "Free Chat" folder.  smile

--Cindy

I posted it here just to encourage you to continue discussing about Mars... but maybe the interest is now getting low, due to over-extending mission.  sad  It's a pity, I think the MER missions are getting more interesting day by day!.

#40 Re: Unmanned probes » Spirit & Opportunity *6* - continue on from thread "5" » 2004-05-11 02:55:28

Uhh, forgive my ignorance, but what's that white thing in the upper right corner?

An alien spaceship... from the Martian point of view tongue : infact, it is a piece of a spaceship coming from outside Mars.
Serioulsy, it is the Opportuniy's heatshield, detached from the lander before the lander started bouncing over Mars surface.

Luca

#41 Re: Unmanned probes » Spirit & Opportunity *6* - continue on from thread "5" » 2004-05-10 15:07:10

I found a new interesting way to look at multi-filter images:
cycle1-t.gif
http://jumpjack.altervista.org/immagini/cycle1.gif]zoom

Can you see how "invisible" details appear when cycling into IR part of the spectrum?

"No life on Mars", enjoy this new animation!  tongue


I also found a very interesting program to automaGically create panorama images:
http://www.panavue.com/]PanaVue

I'll se if I'll be able to create a full Endurance spectrum-cycling animation... although I suppose it will be several MB long.

Luca

#42 Re: Unmanned probes » Spirit & Opportunity *6* - continue on from thread "5" » 2004-05-10 02:33:06

Great 3-D image, Stu! Thanks.
    It's difficult to judge how steep those sandy slopes really are but I would guess something like 20 to 30 degrees(?)

Have the rovers a system to detect their inclination? And have they a measurement of the pancam inclination? Maybe if we know that the rover is exactly horizontal and we know the inclination of the pancam when pointing to two different points of the closer slope, we could determine how steep it is, as probably we can determine de distance of the two points thanks to the presence of a couple of camera on the pancam...  ???

#43 Re: Unmanned probes » Spirit & Opportunity *6* - continue on from thread "5" » 2004-05-10 01:46:59

See today so many post from cassioli. If you look at last actions almost all are from cassioli. I think 95% post last 2 weeks are from cassioli mostly pics of blue Mars and animations. He needs attention like a child. See this look that.
He floods this forum with his "discoveries" and I hope that he will  reduce little bit his activity.

I like posting to this forum, you like counting how many posts I make.
Each person likes wasting his time in his own manner... tongue

#44 Re: Unmanned probes » Spirit & Opportunity *6* - continue on from thread "5" » 2004-05-09 14:11:04

ifrance, ibelgique, dunno if there are other "i's" around, you can try...

(EDIT:  yes there are for Spain, Italy, Switzerland, Monaco, Quebec. google ifrance, and scroll to bottom of page...)

(EDIT 2: http://www.iitalia.com/heberg/]http://w … om/heberg/

there ya go mate, hope they offer the same stuff as iBelgique: 100Mb, unlimited traffic...

...and they only allow max 1 MB files to be uploded! sad :reallymad:

(EDIT 3: Looks like it's unlimited diskspace??? As far as i can decypher Italian (not very good, heh))   

http://www.iitalia.com/_site/cre.start] … /cre.start

Warning: it is pop-up hell...

I'll see, thanks.

Did you know we have so many craters here "at home"?  :;):

http://www.solarviews.com/eng/tercrate.htm]Earth craters

These make me think that the material at the bottom of Endurance may be what remains of the meteorite...  ???

I found also i(italia)... but it does not allow files bigger than 1 MB!!!! sad
Others?
Just ftp hosting?

#48 Re: Unmanned probes » Spirit & Opportunity *6* - continue on from thread "5" » 2004-05-09 11:53:44

I gotta say, i appreciate musing over Cassioli's prolific animations, images and interpretations, all bazillion of em! more power to ya Luca!

now only if all his links worked, some work but some are dead 404s or bring up a generic altervista catchpan page....
for instance the latest ones, http://jumpjack.altervista.org/immagini … zoom-1.gif and http://jumpjack.altervista.org/immagini … es.avi]the avi -wha happen? ???

...by the way what software do you use to edit all those images together and animate them?

Very funny  ???  If I fix one file, other files lose the R attribute by themselves...  :rant:
Does anybody of you know a free hosting site with around 100 MB or more available for each user?

Luca

#49 Re: Unmanned probes » Spirit & Opportunity *6* - continue on from thread "5" » 2004-05-09 11:51:23

I think the animations are really cool and thank him for making them.

Your computer has a down arrow key and a "PgDn" key, right?

        -- RobS

Yes, very useful indeed...  :;):  But I usally prefer the mouse-wheel.   big_smile

Luca

#50 Re: Unmanned probes » Spirit & Opportunity *6* - continue on from thread "5" » 2004-05-09 11:40:10

I think cassioli post too many animations on this forum.

If you don't like them, don't look at them...

I understand to post 1-2 per week but this is too much. He discuss with him self on this forum.

I say so complex&clever things that nobody knows what to reply... tongue  Or maybe my posts are just interesting to be read, and no reply is needed...

Are you cassioli boring at home or what?

A lot, indeed, so I found something to spend my spare time. smile
