NASA's distant Voyager 2 probe has sent a 'heartbeat' signal to Earth after mission control mistakenly cut contact, the US space agency said Tuesday.
Launched in 1977 to explore the outer planets and serve as a beacon of humanity to the wider universe, it is currently more than 12.3 billion miles from our planet – well beyond the solar system.
But on Tuesday, Voyager project manager Suzanne Dodd told AFP the team enlisted the help of the Deep Space Network – an international array of giant radio antennas, plus a few that orbit Earth – in a last-ditch effort to re-establish contact sooner. But while engineers can now see a heartbeat – in technical terms, the carrier wave associated with Voyager 2 – they can't yet read the information signal that shapes the carrier wave, which conveys all the data collected by the spacecraft.
