| Keywords: Mars Viking 22a002.png en Original Caption Released with NASA Image <br /> This rocky panoramic scene is the second picture of the Martian surface that was taken by Viking Lander 2 shortly after touchdown on September 3 at 3 58 PM PDT Earth received time The site is on a northern plain of Mars at about 48 N Lat 226 W Long known as Utopia Planitia The picture sweeps around 330 degrees in azimuth starting from northwest at the left through north above the sampler arm housing past east where the sky is bright at the center and southeast toward the right above the radioisotope thermoelectric generator cover The surface is strewn with rocks out to the horizon ranging in size up to several meters across Some pitted rocks resemble fragments of porous volcanic lava Other rocks have grooves that may have been eroded by windblown sand and dust Although fine-grained material is seen between the boulders no sand dunes are evident The dip in the eastern horizon at the center is an illusion caused by an 8-degree tilt of the Lander toward the west Actually the terrain is more level than that at the Viking 1 site The horizon toward the left of the panorama northwest appears featureless indicating that it may be several kilometers distant The sky at the center east is bright because the sun was above but out of the picture at 10 AM Mars time Toward the right southeast the rocks that are silhouetted against the skyline indicate that the horizon is much nearer probably because of a slight rise in that area of the terrain The circular high-gain antenna at the right has clots of fine-grained material adhering to the lower half some of which appeared to have been sliding downward while the camera was scanning the area At the extreme right the banded appearance resulted because the camera continued to scan while it was no longer moving in azimuth Any motion or other variation in the scene would show up as a change in successive lines Own work based on images in the http //pds-geosciences wustl edu/geo/vl1_vl2-m-lcs-2-edr-v1/vl_0002/ NASA Viking image archive Roel van der Hoorn Van der Hoorn 2010-02-17; original photo was taken 1977-09-03 I used the original http //pds-geosciences wustl edu/geo/vl1_vl2-m-lcs-2-edr-v1/vl_0002/a0xx/22a002 sur 22a002 sur image from the http //pds-geosciences wustl edu/geo/vl1_vl2-m-lcs-2-edr-v1/vl_0002/a0xx/ NASA Viking image archive converted it to png and manually removed the noise Except for the conversion this was done in Adobe Photoshop CS2 and Adobe Photoshop CS4 The original file by NASA is in the public domain and so is this new one I created this image as a replacement for the File Vl2 jpg This file was created by NASA but the quality is not very high especially on the right side Using the original pictures from the Lander archive resulted in a higher quality image Van der Hoorn The image is based on an original image from NASA to which the following copyright statement is applicable PD-USGov-NASA Mars landscapes Viking mission Utopia Planitia | ||||
