New Mars Forums

I fixed some animations of mine which were no more available for download due to my web-hosting service error (why didn't you tell me you were not able to see them?!?).
They are:

http://jumpjack.altervista.org/immagini … Hills-anim sol 8-88 (color)

...just to have fan while waiting for new images.  :rant:

I hope these links work now

For some strange reasons, if I overwrite an existing file in my webspace (I did it to upload an optimized version of the animation), the file becomes no more available. :rant:
I discovered it just now, but now I am at work, and the original animation file is at home, so you'll have to wait till 16:00 GMT to have the animation available again. 

Sorry for the incoveneince.

I think that if we'll see a dark area in place of the "big puddle" in IR filtered images at any time of the day, we would be near sure it's ice.
BUT, if we'll not see a dark area, we will NOT be sure it is NOT ice, as it could be covered by dust warmed by sun...  ???

I don't know if the rover has an "ice-detector"... but it was sent there to look for water evidence, so it probably has it. Or was te mission objective just to look for evidence of PAST water?  ???

Puddles, springs or "coldspots"?!?
This site is even  more interesting than we expected: following "suggestion" by chaosman, I did some searches and experimentations with Opp's images. I found several images of "puddles", and I also noticed a strange thing: in IR version of images, they appear surrounded by a darker area, i.e. a colder area. So, are they just puddles, are they water springs, are they evidences of water coming from under the soil and freezing, or what?!?

I prepared some color version of the "puddles" I found: for two of them I was even able to build 2 color photo.

Please compare these two images:

and

Are they the same thing?!? (Backshell & parachute)

Here it is a map of the area:

Is there a method to know rover orientation and pancam orientation?

Animation fixed (there was one wrong frame), updated (also with a color frame now!) and optimized (no more headache! )

A new version of the spreadsheet is online: now it shows detailed informations about image (rover, camera, position, command...), and it also allows determining corresponding Mars time of current Earth time.
It is also included a "handheld version": if you have a PDA capable of reading Excel files, you will be able to know current Mars time... at any time!

If only Spirit wasn't so in a hurry!   :rant: 
Look at what interesting layered little rock is there!

A strange moment to take a snapshot (dawn? sunset? it is the first time, I remember... or not?).
And... what the hell is "L0" filter?!? I always thought they were L1-L7, with L1=empty filter!  :rant:
