In February of the same year, the DSS-43 space station, the only one capable of sending messages to Voyager 2, closed its signal transmission antenna due to its service time approaching 50 years, aging hardware, and the need for maintenance and major upgrades.
Humans and Voyager 2 became one-way contacts, only able to "listen," but not able to "speak" to it.
According to the original plan, this maintenance would last for 11 months and be completed in January 2021, thus restoring the mutual "communication" with Voyager 2.
However, due to some unforeseen force majeure, Harrison Clark saw in the historical materials that the maintenance was not completed on time but was delayed until August 2021.
But in July 2021, Voyager 2 "vanished" out of the blue.
Humans could not only not "speak" to it but also no longer "hear" its voice.
It mysteriously disappeared.
Scientists at the time had predicted that human contact with Voyager 2 would be lost in 2025, four years ahead of schedule.
