View from Venera 13
This is a panoramic surface image by Venera 13, a Soviet mission
that landed at 7.5°S, 303.5°E on March 1, 1982. The effect of
sunlight filtering through the dense atmosphere appears to give the surface
an orange tint. However, the accuracy of the colors in the panorama depends
in part on calibration with the color bar shown in the image, and the
high atmospheric temperature and sulfuric acid in the atmosphere may have
significantly altered the color bar in unexpected ways. The wide-angle
lens used causes the distortion apparent on the edges of the panorama.
The saw-toothed object at the bottom of each image is the foot of the
lander, and the circular object just above is part of the protective covering
for the camera system. Chemical analyses performed by the Venera landers
indicate that most venusian rocks, including those shown here, are basaltic
and therefore black or gray. Note that there does not appear to be much
soil on the surface.
