摘要

描述
English: First Clear Image From Mars Surface (Viking 1, July 20, 1976).

This is the first "clear" image ever transmitted from the surface of Mars. 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 center is about 10 cm across.

NOTE: See File:Mars 3 Image.png for the first "actual" image transmitted from Mars - Mars 3 lander (Soviet Union), December 2, 1971 - the Mars 3 image, however, was unclear and contained "nothing identifiable" according to the Soviet Academy of Sciences (ref).

(二次使用本文件)		 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.
其他版本 I created this image as a replacement for the now deleted image Mars first lander image.gif. This file was created by NASA, but the quality was not very high. Using the original picture from the Lander archive resulted in a higher quality image.
