Voyager 1 is sending strange data. NASA doesn't understand what's going on

A team of engineers from NASA's Voyager 1 spacecraft examines the telemetry of an interstellar probe. he works

normally, receives and executes commands from the Earth,and collects and sends scientific data. The problem is that the readings of the attitude articulation and control system (AACS) do not reflect what is actually happening on board.

AACS controls 45-year-old's orientationspace ship. Among other things, the system keeps Voyager 1's antenna pointed straight toward Earth. So far, it performs its main function. Without this, communication with the probe will immediately stop. However, the telemetry it sends is invalid. For example, they may appear to be randomly generated or do not represent any possible state that the AACS might be in.

It is not clear at this time what is the cause.problems and whether it can be fixed. So far, it has not led to the operation of any on-board failure protection systems. They are designed to put the spacecraft into “safe mode,” a state in which only basic operations are performed, giving engineers time to diagnose the problem. The Voyager 1 signal has also not weakened, indicating that the high-gain antenna remains in the prescribed orientation relative to the Earth.

The team will continue to closely monitorsignal while continuing to determine if bad data is coming directly from AACS or another system involved in creating and sending telemetry data.

Voyager 1 is now at a distance of 23.3billion kilometers from Earth or 20 hours and 33 light minutes from us. This means that it takes approximately two days to send a message to Voyager 1 and receive a response. However, as noted in the NASA Jet Propulsion Laboratory, the mission team has already become accustomed to this delay.
