In 1972, NASA launched the exploratory space probe Pioneer 10. According to Leon Jaroff in Time, the satellite's primary mission was to reach Jupiter, photograph the planet and its moons, and beam data to earth about Jupiter's magnetic field, radiation belts, and atmosphere. Scientists regarded this as a bold plan, for at that time no earth satellite had ever gone beyond Mars, and they feared the asteroid belt would destroy the satellite before it could reach its target. But Pioneer 10 accomplished its mission and much, much more. Swinging past the giant planet in November 1973, Jupiter's immense gravity hurled Pioneer 10 at a higher rate of speed toward the edge of the solar system. At one billion miles from the sun, Pioneer 10 passed Saturn. At some two billion miles, it hurtled past Uranus; Neptune at nearly three billion miles; Pluto at almost four billion miles. By 1997, twenty-five years after its launch, Pioneer 10 was more than six billion miles from the sun. Radio communications were finally lost with Pioneer 10, at the edges of our solar system, on January 23, 2003.

But despite that immense distance, Pioneer 10 continued to beam back radio signals to scientists on Earth. "Perhaps most remarkable," writes Jaroff, "those signals emanate from an 8-watt transmitter, which radiates about as much power as a bedroom night light, and takes more than nine hours to reach Earth.'" The Little Satellite That Could was not qualified to do what it did. Engineers designed Pioneer 10 with a useful life of just three years. But it kept going and going. By simple longevity, its tiny 8-watt transmitter radio accomplished more than anyone thought possible.

So it is when you and I offer ourselves to God in faithful obedience. It's just incredible what God can do through little 8-watt transmitters like me and you, when we're turned on for him.
