NASA's Voyager spacecraft continues to defy farewell.

NASA engineers have found a hidden trove of power within one of Voyager 2's parts that could prevent them from having to shut down a key instrument for another three years. Both Voyager 2 and its twin, Voyager 1, are almost 45 years old, way older than their original life expectancy. They were intended to study Jupiter and Saturn, their moons, and Saturn's rings. For the two-planet mission, they were built to last just five years.
