Voyager 2 flew so far below the plane of the solar system after Neptune that only one antenna on Earth can still send it commands, a 70-metre dish outside Canberra, which went offline for eleven months of repairs in 2020 while the spacecraft flew on in silence, unable to be told anything.
Voyager 2's extreme trajectory beyond Neptune leaves it communicable only through a single 70-meter antenna in Australia, which was offline for 11 months in 2020, leaving the aging interplanetary probe unable to receive commands during that period.
