File:Mars Viking 12a001.png


Description This is the first "clear" image ever transmitted from the surface of Mars (see File:Mars 3 Image.png for actual first image transmitted from Mars - but unclear and "nothing identifiable"). The Viking 1 image was taken only a few minutes after the landing. Engineers decided to program the probe to quickly take and send an image of a footpad (in this case footpad number 3) because it was feared that earlier Soviet probes, which stopped transmitting shortly after touchdown, may have sank into quicksand. If Viking 1 met the same fate, they wanted to know about it this time. Some speculate that the cloudiness on the left side is due to dust left over from the landing. The cameras scanned one vertical strip at a time such that by the time the scanning moved to the center of the image, the dust had allegedly settled. The large rock near the centre is about 10 cm across.

I used the original 12a001.bb1 image from the NASA Viking image archive, converted it to .png, manually removed the noise and finally increased the brightness and contrast by 20. Except for the conversion, this was all done in Adobe Photoshop CS2. The original file by NASA is in the public domain, and so is this new one.
