What was our concept about extra-terrestrial life at the time of launch of Pioneer 10? What step was taken to save us from imaginary apprehensions?

Answer»

By the time Pioneer 10 was launched in 1972 many scientists began to develop a strong belief about possibility of more advanced life on other celestial bodies. Some scientists were also apprehensive of possible attacks from alien civilizations. Pioneer was to go beyond our solar system after passing through near Jupiter. It was anticipated that pioneer may come in contact with any advanced civilization during its eventual voyage.

It was feared that the advanced civilization may attack Pioneer 10 after considering it as an attack by human civilization. A plate was fixed on Pioneer 10 to rule out this misconception. The plate showed figures of a man and a woman with friendly posture and a message in sign language to show the real intention of voyage of Pioneer 10.
