Communication with the space probe Voyager 2, which was interrupted due to a command error, was completely recovered
Launched on August 20, 1977, Voyager 2, an unmanned space probe intended to explore outer planets and moons beyond Jupiter, will communicate with Earth by command sent from Earth in July 2023. was cut off by mistake. However, according to NASA, communication with Voyager 2 has since been fully restored.

Voyager 2 left the solar system in November 2018. After that, it is moving away from the earth at a speed of 5 km per second, and is flying about 19.9 billion km from the earth at the time of writing the article.

Even after Voyager 2 left the solar system, it was still sending regular data to Earth. However, it turned out that there was a mistake in the command NASA sent to Voyager 2 in July 2023, and the direction of the Voyager 2 antenna used to communicate with the earth was shifted by two degrees. Due to this mistake, communication with Voyager 2 was lost.

After that, NASA's Deep Space Network (DSN), which communicates with Voyager 2, announced that it was able to detect a carrier signal from Voyager 2. The carrier signal is used by Voyager 2 to transmit data to Earth, and although it was too weak to extract the data, we were able to confirm that Voyager 2 was still working.
Earth to Voyager...????

The Deep Space Network has picked up a carrier signal from @NASAVoyager 2 during its regular scan of the sky. A bit like hearing the spacecraft's “heartbeat,” it confirms the spacecraft is still broadcasting, which engineers expected. https://t. co/tPcCyjMjJY
Voyager 2 originally had a mechanism to periodically reset the flight attitude as a fail-safe, and it was supposed to automatically face the earth in October 2023, so if you wait for the reset in October Voyager 2 I was able to expect recovery of communication with. However, the arrival of this carrier signal may allow the command to quickly reorient the antenna.
DSN sent a command to correct antenna orientation from its facility in Canberra, Australia, to Voyager 2, which is more than 19.9 billion kilometers away. According to NASA, it took 18.5 hours each way for the command sent from Earth to reach Voyager 2, and then another 18.5 hours for Voyager 2 to confirm that it had corrected its antenna orientation as commanded. He said. In other words, it took 37 hours from the time the air traffic controller sent the command until he could see the result.
At 12:29 a.m. EDT on August 4, 2023, Voyager 2 confirmed receipt of observation data transmitted from Voyager 2, and Voyager 2 is operating normally and maintaining its planned flight trajectory. I understand.
The official Voyager program X account said, 'Can you hear me? Last night, thanks to quick wit and a lot of co-operation, full communication with Earth was restored. I'm maintaining it. Thanks to you, I can finally call home.'
Can you hear me now?

Last night, I reestablished full communications with Earth thanks to some quick thinking and a lot of collaboration. I'm operating normally and remain on my expected trajectory. So glad I can finally phone home.
