| Voyagers 1 and 2 were launched from the Kennedy Space Center at Cape Canaveral in 1977 aboard Titan-Centaur expendable rockets. More than two decades later, their travels have taken them past Jupiter, Saturn, Uranus, and Neptune. In 1993 they recorded the first direct evidence of the heliopause, the boundary that separates Earth's solar system from interstellar space. The heliopause region of space is the last vestige of influence from the solar wind generated by our sun. Today these remarkable little travlers continue their journey across intersteller space. |
