1. Voyager Spacecraft Marker

Inscription. Voyagers 1 and 2 were launchd in 1977 to meet a solar-system alignment that occurs only once every 176 years. Both spacecraft sent back valuable pictures and information of Jupiter and Saturn and their satellites. Voyager 2 sailed on to explore Uranus and Neptune. Engineering subsystems provided power and stabilized the spacecraft. On-board computers controlled flight and transmitted data to earth independent of human control. These systems made the Voyagers the most intelligent spacecraft ever built. The Voyagers now are exploring near the edge of our solar system and will return useful data well into the 21st century.

Erected 1993 by the American Society of Mechanical Engineers.
