NASA hears ‘heartbeat’ of Voyager 2 after losing communication | CNN - eviltoast
Voyager 2’s mission team was able to detect a signal from the spacecraft confirming it’s still operating as normal after an errant command caused a loss of contact.

The Voyager mission team at NASA has been able to detect a signal from Voyager 2 after losing contact with the spacecraft, which has been operating for nearly 46 years.

“We enlisted the help of the (Deep Space Network) and Radio Science groups to help to see if we could hear a signal from Voyager 2,” said Suzanne Dodd, Voyager’s project manager at NASA’s Jet Propulsion Laboratory in Pasadena, California. “This was successful in that we see the ‘heartbeat’ signal from the spacecraft. So, we know the spacecraft is alive and operating. This buoyed our spirits.”
