NASA has confirmed that one of its greatest ever missions, Voyager 1, is back in business with communications restored following an incident in October that had led to the veteran spacefarer losing its voice.
Now 47 years old, Voyager 1 is 15.4 billion miles (24.9 billion kilometers) from Earth, a distance that grows greater with every passing second. With the power supply from its decaying plutonium dwindling, only four of its instruments remain operational — and surprisingly so, given they are now all working at temperatures lower than they were originally designed for.
