About Pioneer 10 Leaves the Solar System
On June 13, 1983, NASA's Pioneer 10 crossed the orbit of Neptune and became the first man-made object to travel beyond every known planet — venturing into the vast, cold quiet of interstellar space. Launched in March 1972, the small spacecraft had spent more than a decade threading past Jupiter's crushing storms and riding the solar wind ever outward, its golden plaque carrying a greeting from Earth to whatever might one day find it. The signals Pioneer 10 sent home grew fainter with every passing year, but they kept arriving — faint whispers of a lone craft sailing deeper into the cosmos than anything built by human hands had gone before.
