Spirits Latest Images

Have the large colour images that have been coming down from Spirit been
compressed to make the file sizes smaller?

They seem very soft, not like the colour pics we have from Pathfinder where
you can see a temendous amount of fine textural detail in the soil and socks
that are close to the lander. That seems missing from the Spirit images.

e.g.
http://www.jpl.nasa.gov/mer2004/rove...ons/image-2.ht
ml

That image and several others are crops of much larger images. You need to
find the source images that are much higher resolution, eg.
http://marsrovers.jpl.nasa.gov/galle...a/PIA04995.jpg
(8MB)
and
http://marsrovers.jpl.nasa.gov/galle...color_panorama
_sol6-A6R1_med.jpg (4MB)

These are good pages to start from:

I just downloaded the high res image PIA05015.tif and it's 67.51
megabytes big.

I couldn't tell the difference between the hi-res TIFF and the corresponding
JPEG. I have a suspicion that NASA convert what they have to TIFF just to
put the image in a lossless format after-the-fact.
