NASA hears ‘heartbeat’ signal from Voyager 2 probe a week after losing contact

More than a week after accidentally cutting off communications with the Voyager 2 probe, NASA officials heard a hopeful signal that may allow them to reestablish contact with the interstellar traveler months ahead of schedule.

On Aug. 1, NASA’s Jet Propulsion Laboratory (JPL) Twitter account confirmed that engineers had received a transmission called a carrier signal from Voyager 2 — which is currently cruising beyond the edge of the solar system more than 12.3 billion miles (19.9 billion kilometers) from Earth.
