An excerpt from a piece I am writing.
Pioneer 10 left earth on March 2nd, 1972; it was the first space craft to leave the solar system. Earth lost contact with the probe on January, 23 2003. We had insignificant power to reach the probe. Pioneer 11 followed its predecessor on April 6th, 1973. Contact was lost on November 30th 1995, it’s antenna could not be turned to point towards Earth. Voyager 2 was launched on August 20th, 1977. Less than a month later on September 5th, 1977 Voyager 1 was launched. By 2015 both Voyagers had lost camera ability, two years later they stopped transmitting data back. In 2022 the Voyagers stopped sending data. In 2025 the Voyagers stopped receiving data.
All of these probes had one thing in common, they all contained messages from Earth including maps, schematics, populous information, and other details about the human race. Some argued that if there was intelligent life out there that it was enough for an alien species to invade Earth. Most people believed that none of the probes would ever find any intelligent life.
