A few questions: how does it still have power? How is it still sending a signal back to earth? I can barely catch wifi in every room, yet from billions of miles away it can send data.
Uses a decaying nuclear source to produce heat that keeps the electronics from freezing, and is converted to electricity using sort of a reverse pelter junction technology. The signal is so faint it requires a 150 foot dish to capture it, and the data rate is so slow it takes weeks to collect even very small amounts of data.

I remember reading that the signal back to earth is not as strong as a two "D" cell battery flashlight.

In other words, an advanced version of HughesNet?
