· In 1972, NASA launched the exploratory space probe Pioneer 10. The satellite’s primary mission was to reach Jupiter, photograph it and its moons, and beam data it collected about this giant planet back to earth. Scientists regarded this as a bold plan, because up until then no satellites had gone beyond Mars, and they feared the asteroid belt would destroy the satellite before it would ever get to Jupiter.
But Pioneer 10 accomplished its mission and much, much more. Flying past Jupiter in November 1973, the space probe continued its incredible journey toward the edge of our solar system. At one billion miles from the sun, Pioneer 10 passed Saturn. At some two billion miles, it hurtled past the planet Uranus, then past Neptune, at nearly three billion miles, and Pluto, at almost four billion miles. By 1997, 25 years after its launch, Pioneer 10 was more than six billion miles from the sun.
And it’s still going. Though now nearly 8 billion miles from the sun, the satellite keeps sending signals; some were received as recently as April 27, 2002. And despite that immense distance, Pioneer 10 continues to beam back radio signals to scientists on Earth. Commenting on the Pioneer 10 in Time magazine Leon Jaroff says, “Perhaps most remarkable, is the fact that those signals emanate from an eight-watt transmitter, which radiates about as much power as a bedroom night-light, and take more than nine hours to reach Earth.”
