Voyager 1 Faces Critical Memory Error, Endangering Its Mission

NASA engineers are working against time to resolve a critical memory error in Voyager 1's Flight Data System, risking the end of its historic interstellar mission.

Voyager 1, launched in 1977, is currently unable to transmit useful scientific or engineering data back to Earth due to a corrupted memory in its Flight Data System.
NASA's attempts to reboot the system have failed, and engineers are considering sending commands for old flight modes to diagnose the issue.
The spacecraft, now nearly a light-day away from Earth, continues to send a carrier signal, indicating it is still operational.
Engineers face challenges due to the lack of a simulator for testing potential fixes and the advanced age of the spacecraft's technology.
Voyager 1's mission, which has vastly exceeded its expected lifespan, has provided invaluable data on interstellar space.
