NASA 'shouted' a command to the spacecraft across over 12.3 billion miles of space using the Deep Space Network, telling it to turn its antenna back to Earth.

after a tense two weeks of not hearing anything from the probe. On July 21st, the agency lost contact with Voyager 2 following a series of planned commands that mistakenly pointed it two degrees away from our planet. While it is scheduled to automatically reset its orientation on October 15th, it's not surprising that NASA scientists didn't just wait for that date to know whether the spacecraft is still running.
For a few days after July 21st, NASA wasn't even sure what the spacecraft's condition was. It wasn't until August 1st that multiple ground antennas from the Deep Space Network were able to detect a carrier signal from the probe. A carrier signal is what a spacecraft uses to beam data back to the ground, but NASA said the one DSN detected was too weak to be able to transmit any information.
Instead of simply waiting for October, Voyager's ground team decided to take action. They concocted a plan to"shout" a command to the spacecraft across over 12.3 billion miles of space using the DSN, telling it to turn its antenna back to Earth. The whole process illustrated just how vast outer space truly is: It took 18.5 hours for that message to reach the probe, and another 18.
