For those who haven't seen it yet, a new HiRISE image has just ben released showing Spirit's Lander off to the side of Bonneville Crater...

http://hirise.lpl.arizona.edu/ESP_025815_1655

(Was that a HiWISH of yours Doug?)

Here's what the lander looked like on 29 Jan...

Attached Image


Wouldn't it have been great if we'd had a HiRISE portrait of the lander and rover just after landing? It might have looked something like this... (I've tried to get the scale right by cloning Spirit from the same image)...

Yup. They didn't QUITE get it right - they were about 140 meters east of what I was asking for....as they didn't quite get the backshell and parachute in color as well.

I have the same request submitted for Meridiani, Color over Eagle Crater.

Here's an attempt to tweak the color to look similar to what an overhead view might look like:

Beautiful colours, ugordan, as ever... smile.gif

The new HiRISE image inspired a new astropoem, which is here if anyone wants to have a look...

Natural or not, those earthy brown tones from the NASA rendering are more pleasing to my eye than the orange-red versions.

I'm not an expert at all in optics, but I suppose that even if the ambient light is very red, in low light levels the black and white vision (rods) is more efficient that the color vision (cones). So, when displaying an image with normal Earth brighness levels, lower saturation may preserve better the original visual experience.

Here's my version:

Attached Image


In GIMP:
1. Go to Balance color and slide the tree balances +10 towards red and -10 towards yellow.
2. In Hue and saturation, drop saturation -40.
3. In Brightness and contrast, +20 brightness and +30 contrast.

Or, in other words - we're guessing and it's just an artistic judgement call.

This is it... tested and approved on VL1 and VL2 images at JPL-IPL in 1981-1982 wink.gif
