Oops! NASA has temporarily lost contact with the Voyager 2 spacecraft.
A series of planned commands sent to the spacecraft on July 21 inadvertently caused its antenna to point 2° away from Earth. NASA can no longer send commands or receive data from Voyager 2 via the DSN.
Voyager 2 is programmed to reset its orientation multiple times each year to keep its antenna pointing at Earth; the next reset will occur on Oct 15, which should restore communications.

Unbekannter Ursprungsbeitrag • • •Of course, this is not the first time the twin Voyager spacecraft have been out of contact with earth. There have been computer glitches and comm. outages before. But nothing NASA engrs. cannot fix.
The longest outage, ~11 months long, was experienced by Voyager 2 in 2020-2021, during upgrades to the 70-m antenna at the DSN site in Canberra, Aus. During this period, commands could not be sent, but data was still received using three 34-m antennas.

Als Antwort auf AkaSci 🛰️ • • •Let's ponder for a moment that the computing resources on the Voyager spacecraft are from the 1960s, with clock speeds measured in KHz and RAM in kbytes, running hand-crafted software, crammed into 4K of 18-bit wide plated-wire memory (similar to but better than core mem).
The hardware and (upgraded) software are still functioning after 46 years in space.
