MER-B Image Compositions

Mars Exploration Rover B, popularly known as opportunity, image compositions by Jill England.  January and February 2004.  All images are copyright 2004 by Jill England.

The original source images are the property of JPL, NASA, and the United States of America .  You can find all of the original images on the NASA and JPL web sites under raw images.  For color images from these raw images you need to mix the RED, GREEN and BLUE channels appropriately with a tool such Photoshop.  This is all I have done to produce these images and I encourage you to mix your own using the same data.

Note: Image suffixes are the filter numbers L457 indicates that L4 was used for the red channel, L5 was used for the green channel, and L7 was used for the blue channel.

These images are not supported nor do they represent any work by scientists or other researchers in the Mars field.  They are purely my own compositions to satisfy my own curiosity.  Any assertions that they ‘prove’ any particular theory should be backed up by further, actual, scientific, research.

This is a colorized Microscope image.  I used colors from  an L457 channel image of this same rock.  (Left, 4, 5, 7 is a ‘normal’ looking color composite)

1P129510661ESF0312P2553L456.jpg

Pancam Left image of Backshell. Each color channel de-speckled to remove compression artifacts. Image probably has brighter blue speckles in it that are not visible due to using the 6 instead of 7 filter blue filter

P129517359EFF0312P2378L457.jpg

Left 457 Color of snout investigation.  Note flag on instrument head has correct colors.

Image was brightened to compensate for down stopping of the camera due to bright reflections off of solar panels and aluminum and white arm.   Solar panel was not brightened during contrast correction.

Note that size of spheres relative to arm indicates that they are marble sized and not bb sized.  Note color is pretty accurate at a blue-green aqua color. Very small spheres of a greenish color were found in pyroclastic deposits on the moon.

Suggest that arm’s be painted neutral gray instead of white on future missions. (Like anyone will listen)

1P129517747EFF0312P2378R721.jpg

Right camera 721, mostly infra-red image. Notice that the marbles are a purplish color since they are black via the infra-red filters.  Obviously this image is stretched beyond colors that humans can normally see.  Compare to previous image

1P129518067EFF0312P2378R721.jpg

Right 721, filter R1 and L7, BLUE, are identical. R7 is identical to L2, dark red.  This image shows colors beyond the normal human spectrum emphasizing the marbles as being a purplish color. They absorb almost all red.

Left 2, 5, 7 -- Note various sizes of other blue rocks that are likely the same material as the marbles. Blue into the distance shows that the marbles cover an area as far as can be seen. Not just in this crater.

Left 2, 5, 7 – A good context view.  I like it.

backshell.jpg

Cropped and magnified close up of backshell from earlier image. Color Saturation and contrast were increased.

hillside_from_lander.jpg

First images from lander showing specular (very reflective) blue rocks on hillside of crater.  Close ups later revealed millions of little glass balls from marble sized up to the softball sized ones seen in this image.  These are probably fused glass from a very large pyroclastic flow that covered this area in layers in the distant past, though not so long ago as to erase the evidence

Perhaps this deposit originates from the enormous impact zones of the southern hemisphere.  An area that is chewed up by thousands of impacts.


leftFrontCrater_fromLander.jpg

Another original view of left front from the lander, I like this one because of all the sky.  Colors are close to human perception.  Reds are VERY red because of the hematite (red soil like in Kauai or Georgia )).  Again note the very specular blue stones.  Near field shows the airbag compression of the marbles into the soil

outcrop_composit2.jpg

This is a mosaic image to kind of show the extent of the marbles and sand and rocks at the first study sight.  It is a bit distorted and various different filter sets from the left camera were used in the images.  Images had slightly different magnifications.  Overall it is pretty representative and shows the scene as it would appear under bright light.

snout_composit-457.jpg

Left 4, 5, 7 image composite of first study sight.  The above microscope image was taken from lower left of the rock in front on lower right, this rock was called snout.  This was my color pallet for adding colors to the microscope image previous.
