The machine may even outlast the solar system itself, which is expected to expire in another 5 billion years when the sun swells into a red giant and engulfs the inner planets...
...surprise of Pioneer's voyage so far is the discovery that the boundary of the sun's atmosphere, or heliosphere, the bubble of particles blown into space by the solar wind, is much farther out than supposed.

But even now the spacecraft's instruments show no decline in the heliosphere's strength, only what seems to be a swelling and contraction connected with cycles of solar activity...
