The sign by the Viking lander test article. It reads


VIKING LANDER
(proof test article)
First Spacecraft to Operate on the Surface of Mars

On July 20 and September 3, 1976, two identical Viking spacecraft successfully landed on Mars. The Viking landers were the first spacecraft to conduct prolonged scientific studies on the surface of another planet.

Instruments aboard the spacecraft provided valuable information on the Martian atmosphere and surface until late 1982. Biological experiments carred out on the Viking landers did not detect signs of life or any of the organic compounds that are abundant on Earth.

The Viking lander displayed here is a "proof test article" used on Earth to simulate the behavior of the actual landers and to test their responses to radio commands.
