#151 Re: Unmanned probes » More 3d anim - warning, large downloads! » 2004-04-05 02:14:26

Once again, these look really great.   However, is there any way to increase the brightness of the first animation?  It's hard to make out details.

I just took the images and put them into the gif animator, without retouching them, it would take too long time to retouch images before creating each animation...  roll
I just wanted to know if you like my job, to know it if it does worth the effort of continuing it.

Ok, if I'll have the time, I'll make other photos... smile

Please submit the links to the images you would like to see animated (I can't animate all images of 160+ Sols...)

I have a good news and a bad news...

The good news is that I succesfully obtained an animated gif of Spirit's hills from Sol 8 to Sol 88.

The bad news is that it shows that those hills are so far, that they actually didn't change at all in their resolution in last 80 sols... sad

This is the animation, quite huge as it is not optimized (it does not worth the effort...)

I also tried to create a color 3d anim of Bonneville, but there are not enough color photos, so it is impossible! sad

Good one, cass! To be honest, i never really liked the red/blue stereos, this kind of stuff, OTOH is great!

Now some brave soul that wants to stitch *all* S&O images together, using 'overflows' so we get a "wild ride on the rovers..."? Bonus points if you do it in stereopairs!

Give me the images, I'll give you the movie! (I'll try, at least).
Looking for all suitable images in ~160 Sols is quite hard...

(I'm serious, that would be *great*... there are some very short sequences of the rovers' pics made already and they're amazing... Don't think it'll be possible in stereo thoug, but you never know...)

Starting with color images would be better, in my opinion.
Waiting for images links--- smile

#156 Re: Unmanned probes » Mars in 3d without glasses! - Look at this amazing image! » 2004-04-02 10:37:36

I did some experiments with Ulead Gif Animator and Spirit images, and I obtained this incredible image:

hills-3d-anim.gif

I obtained it from these images:
[http://www.lyle.org/mars/imagery/2P1340 … 67L7M1.JPG]left
[http://www.lyle.org/mars/imagery/2P1340 … 67R1M1.JPG]right

I created this sequence:
1) left
2) right
3) left
4) right

1) is the same of 3) and 2) is the same of 4), BUT 1) and 2) are centered on point 2, 2) and 3) are centered on point 3, and 3) and 4) are ceneterd on point 4, and this three points are at different distances from the observer:
hills-anim-explain.gif

It looks like it will be quite hard to rech those hills!  sad

I can't find again the color microscope image, so I build it by myself:

Mix:

Maybe the dark "stripes" inside the blueberries are the tipical "stripes" you can see into marble on Earth, and in that strange blue-rock on mars.

Eart's marble sample:

BTW... how many people would see an "artifact" in a similar rock, if the photo came  from Mars rather than Earth?  big_smile

This is the image I am referring to:

But I remember a color version of this, although it is a microscope imagery; does anybody remember it?

#159 Re: Unmanned probes » Spirit & Opportunity *5* - Let's start with new NASA conference! » 2004-04-01 13:12:18

What the hell is there, under the red dust?!?

([http://www.lyle.org/mars/imagery]zoom)

Blue glass?!? Blue marble?!?!? Can you see the strange light reflection?  :hm: I remember we saw the image of a blueberry cut in half by the RAT (sorry, can't remember the link),and it appeared quire similar to that material: maybe blueberries are pieces of that blue rocks (maybe other blue rocks are hidden by red dust), eroded by flowing water?

Very strange, very interesting, very nice... gosh! yikes)

Hej Luca
Thank you for lesson in science especially that nothing is " firm" in science.
We can say that we have many highway on Earth, but we can't say that on Mars.

??? Exactly...

Because everything in science is hypothetical, according Luca.

What's the matter in your post?!?  ???

What I meant is:
If you are sure that no life evidence will be ever found on Mars, you are wrong.
If you are sure that ther IS life on Mars, you are wrong.
The point is: you CAN'T be sure of anything but present discoveries.
NOW ther is no evidence of life on Mars; tomorrow, it could, or it could not.

If all ancient people were sure of the "geocentric theory", nobody would have demonstrated that the Earth is not the centre of the universe: they were sure, what should they demonstrate?!?

Open your mind, if you want to be a scientist.

Luca

#161 Re: Unmanned probes » Civilians flooding NASA with Mars 'discoveries' » 2004-04-01 12:43:17

Luca: What do you mean ". . . we would STILL believe Earth is flat"? Don't tell me that you're one of those Round-Earth crazies! Oh, I get it: It's April 1st. You had me fooled there for a minute.

If you don't use "smilies", I can't understand if you misunderstood my poor english, or if you are kidding...  ???

Luca

#162 Re: Unmanned probes » Civilians flooding NASA with Mars 'discoveries' » 2004-04-01 04:04:07

Hej Luca
Post you made citat off is at same level as your post about ancient roman road on Mars and wheel. Do you mean roman road and wheels on side of crater is scientific approach to Mars debate?
:band:

I just said whot the outcrop looks like.
It could be, it could not be, nobody knows, and I am not trying to convince anybody, and I am not talking about any conspiracy.
It's just an hypothesis.

Unfortunately, your firm skepticism about "no life on mars" is very close to the firm belief of "life on mars" by those guys; you are both wrong: in science nothing is firm, all is hypothetical. IF all scientist were like you, currently we would still believe Earth is flat...

Luca

"On one Web site, an outraged writer accused NASA of intentionally running over the bunny with the rover."
I think the rover hit bunny. This is so sad.

Please....  smile this is the ONLY scientific forum about Mars I was able to find. Don't spoil it inviting dumb people to join dumb threads, let's continue scientifically, ok?  :;):

Luca

#165 Re: Unmanned probes » Spirit & Opportunity *5* - Let's start with new NASA conference! » 2004-03-29 01:20:48

I think you should convert your image to a link, as I noticed not all users of this forum has a broad band connection...

Anyway, I didn't understand the meaning of your post. ???

Luca

#167 Re: Unmanned probes » Spirit & Opportunity *5* - Let's start with new NASA conference! » 2004-03-27 14:24:01

Excuse my ignorance but is it not possible that Methane in Martian atmosphere could arise from photochemical reactions between carbon dioxide,water with incoming UV light?Same thing happens on a bigger scale in Titans atmosphere!
???

I think Titan as active volcanoes... or not?  ???

#168 Re: Unmanned probes » Spirit & Opportunity *5* - Let's start with new NASA conference! » 2004-03-27 14:05:50

Cassioli,are you trying to suggest that some of those round objects or 'pebbles" could be  spherules similar to the ones found at Meridiani?I guess the only way to confirm that is to show that some of these are made up of haematite or not but that would be difficult since individually they wont make up a strong signal as to give themselves up in moss spectra!

In my opinion, it looks like all the planet is covered with those damned  smile  spherlues, as we can find them on two opposite sides of the planet! But I can only base my judgement on their color&shape, until we'll have chemical evidences.

[edit]
Maybe Spirit could examine the huge quantity of blue spherules inside Bonneville? They should be enough for its instruments!!


Luca

#169 Re: Unmanned probes » Spirit & Opportunity *5* - Let's start with new NASA conference! » 2004-03-27 12:52:02

I did a bit of experimentations with raw Spirit data, and I eventually obtained an interesting color mircoscope image.

I would like to read your comments about it:

[http://www.keithlaney.com/SCI/B3.jpg]This image shows very well how little spherules are spread all around the terrain, as you can see the edge between a zone with spherules and a zone without them.
Can you see the low-resolution illusion on the right part of the image?

Luca

#171 Re: Unmanned probes » Spirit & Opportunity *5* - Let's start with new NASA conference! » 2004-03-25 12:30:15

*Yess*

Exactly what I was puzzled over...

How old is that crater? How come the sperules are intact after impact, not to mention the delicate outcropping...

The spherules arrived there AFTER the impact. They are just EVERYWHERE, I don't know why. They are over the surface, they are inside rocks, but they are just all around the rovers, both of them.

You can see them if you look with great care at all photos.
They are like spread around just sand grains in a beach!
Is there anything similar on Earth?

Luca

#172 Re: Unmanned probes » Spirit & Opportunity *5* - Let's start with new NASA conference! » 2004-03-25 12:17:54

Is it me seeing things or are the plains also littered with some sperules?
[http://www.lyle.org/mars/imagery/1P1333 … 1.JPG.html]http://www.lyle.org/mars/imagery/1P1333 … 1.JPG.html

At the beginning, I though the "granularity" of these Mars photos where caused by low resolution; then, I discovered I was wrong: we just have spherules ALL AROUND, ANYWHERE, and they make photo look like low-res!
Try looking at those images thinking you  are looking out of a window, not into a photo: convince your brain you are seing a REAL image, not a photo, and that it is REAL resolution. It's not easy, but if yoy can, you'll eventually see those little spherules everywhere!!

Definitely a strange terrain!

#173 Re: Unmanned probes » Spirit & Opportunity *5* - Let's start with new NASA conference! » 2004-03-23 14:07:53

Maybe microfossils could be seen; the microscopic camera is pretty good.

This is a good point. Does anyone know whether the tools on board are powerful enough to detect microfossils?

The "microscope" camera gives 1024x1024 images representing 30x30 millimeters; this means 0.0293 mm per pixel , or 29.3 um (1 um  = 1/1.000.000 of 1 meter) per pixel.

I don't know the dimension of a cell; any idea?

#174 Re: Unmanned probes » Spirit & Opportunity *5* - Let's start with new NASA conference! » 2004-03-23 14:02:42

Boyboyboyboy... Slowly coming to the realisation... Standing surface water, been there long enough to to some serious sedimentation, erosion...

Can you see it? Close your eyes, try to imagine it...

Open water on Mars!

Or an ice-sea? No matter which one, it must've been a good deal hotter back then...

Just try to conjure up that picture in your mind's eye...

Why "mind's eye"? Use your REAL eyes:

This is only an example of synthetic images you can find at

You can also view how Gusev Crater could appear in the past:

No Opportunity's site images, unfortunately. Maybe he'll create it now, after these news!

Luca

#175 Re: Unmanned probes » Spirit & Opportunity *5* - Let's start with new NASA conference! » 2004-03-23 12:52:06

Ok, let's start. I think the conference is going on right now. Waiting for the Evening News on TV... (Not web TV, just TV smile )
