Archivo: Mars Viking 11b045

Descripción: This picture was taken by the Viking Lander 1 on August 25, 1976 on Sol 35. The large rock just right of the center is about two meters wide. This rock was named "Big Joe" by the Viking scientists. The top of the rock is covered with red soil. Those portions of the rock not covered are similar in color to basaltic rocks on Earth. Therefore, this may be a fragment of a lava flow that was ejected by an impact crater. The part of the Lander that is visible in the lower left is the cover of the nuclear power supply.

Permiso: I used the original 11b045.blu, 11b045.grn and 11b045.red images from the NASA Viking image archive, converted them to .png, manually removed the noise and finally merged them into one image. Except for the conversion, this was all done in Adobe Photoshop CS2. The original files by NASA are in the public domain, and so is this new one.
