An anonymous reader shares a report: The Voyager 2 probe, one of NASA’s most well-traveled spacecraft, has been unable to communicate with Earth for the past eight months. Voyager 2 has been wandering alone at the edge of interstellar space, gathering data some 11.6 billion miles from Earth and sending it back to us. But we haven’t been able to pick up the phone and call back. The only radio antenna that can communicate with the probe, Deep Space Station 43 (DSS43) in Australia, has been offline while NASA completes a series of hardware upgrades. Some of the transmitters on DSS43 haven’t been replaced for over 47 years, according to NASA. To test new hardware, the dish pinged Voyager 2 on Oct. 29 with a few commands. It was the first time since mid-March that a signal was beamed to the spacecraft. And because the probe is so far away, the communication team had to wait over 34 hours for a reply. Sure enough, Voyager 2 received the commands with no problems and sent back a “hello.”
