NASA's Voyager 2 space probe, more that 11 billion miles from Earth, has re-awakened after a period of being shut down.

According to the Jet Propulsion Laboratory (JPL):Voyager operators report that Voyager 2 is stable and communications between Earth have been re-established. The spacecraft resumed collecting data and the science team is now evaluating the health of the instruments. A fault protection routine was triggered that shut-down Voyager's science instruments. The protective software was programed into both Voyager 1 and Voyager 2 to allow the spacecraft to automatically respond and protect themselves in potentially harmful situations. Communications with Voyager 2 take nearly 17 hours to reach the spacecraft and another 17 hours before a response is received back on Earth.

Both Voyager's were launched in 1977 and are now in interstellar space, They represent the most distant human-made objects in the solar system. Each carries a golden disk containing images, sounds, and music from cultures around the world. Graphic instructions in mathematical symbols and diagrams are provided if a Voyager were ever to be intercepted by some alien civilization. The disk was the idea of Carl Sagan who famously coined the term 'pale blue dot' to represent the Earth. His speach is just as relevant today as when the Voyagers were launched over 40 years ago.
