Viking 2

Technically this image does not belong in this collection. I've included it here for several reasons;

  • So newbies can compare the very different landscapes between the original and new landers.
  • So old-timers can compare the very different landscapes.
  • So relative image color, detail and quality can be compared between the old and new landers.
  • Because it's December and I wanted an atypical 'snow' scene on my desktop.

I have processed this Viking image with the exact same software and techniques as are applied to the Opportunity images. The results are close to identical and these scenes appear close to the way you would perceive them if you were there in person. The major difference is that in person the sky would appear more whiteish with slight pink dust tinge along the horizon. The Opportunity images below all have a bright blue sky because the 'Red' filter frequently used is L2 which blocks some human visible red light and lets in red light further in the infra-red range. This has the effect of 'streching' and saturating the color somewhat. (i.e. subtract the some red from the sky and it appears slightly more blue.)

A Viking Frost

Viking color image with high resolution monochrome(red) inserted through center. Color image was allowed to add color to monochrome red image. This has the effect of reducing blue spectrum colors in center section. This image shows a water frost on the ground. Seasons Greetings from Viking 2.

Sol248 Pan-camera Stitch (November 2004)

The following images are sections of a full panarama of the inside of the crater rim. It is steeper to the left and a bit shallower to the right where Opportunity entered the crater. Rigt now (middle of December 2005) Opportunity is moving slowly back toward its entrance point to leave this crater.

The soft dust dune area at the bottom of the crater is behind the rover in these images. Ice clouds appeared over this area after these picture sequences.

'Wall Crawl' Images

Three Image Stitch of 'Iron Flows'

Sol 280. Forward view, three color images. Red is far(deep) red image. These images are overlayed on a BW image of the same section.

Hematite Sand Flows

Sol 281. Black sand/dust is reflective in blue and green filters and NOT reflective in IR. This indicates that it is most likely hematite dust created by thousands of years errosion of the hemetite nodules from the surrounding rocks.

Lets Look Down

Sol 279. Rover is on side of crater to the left of 'flow' section of pan. Detail of sediment ridges. The small long chips are probably the harder ridges chipping off after erosion has removed softer layer material. Note dark hematite sand topped with red dust 'swirls'. Also note grey-blue hematite nodules.

Lets Look A Little Closer

Sol 283. Close up of ground section. This shows more detail of layers and black hematite dust/sand.

Furthest Traverse

Sol287. A little further along crater wall. Opportunity's furthest image along left side of eariler pan. This image is a near true color image. The red is in the infra-red region (deep red) and this causes the sky to look a bit too blue. To human perception the sky would appear more white with pink tones. The bluish tinge on the ground at the left of the image is mostly a reflection from the Hematite nodules and dust of the sky.

IR Furthest Traverse

Sol 287. Infra-red image from right pan camera. IR makes the sky very blue and ground appear yellow. Notice the fairly thick layer of dark material which may have been caused by different sea salinity or ph during a prehistoric period.

Red / Blue Anaglyphs

3D 'Chaotic Region'

Sol 267. Anaglyph of 'flow' section from pan above.

3D 'Ice Clouds'

Anaglyph of far left right section from eariler pan. This image shows high cirrus clouds. The 3D effect is very nice. with the clouds in the background.

3D 'Iron Dust Flow'

Sol 281. This anaglyph image shows the 'flow' features in the center and is an interesting shot of the chaotic region near the crater rim.

3D 'For A Dusty Sky'

Sol 283. Anaglyph image. Turning around to go back toward 'cliff' area. This image shows dust or possibly ice clouds on the horizon. This adds interesting depth to the image.
