Voyager 1 Glitch? NASA   Strange Data From Probe

Working To Understand

NASA's Voyager 1 mission

 launched in 1977, passed into what scientists call interstellar space in 2012 and just kept going

The spacecraft is

 now 14.5 billion miles (23.3 billion kilometers) away from Earth.

while Voyager 1 is still operating

properly, scientists on the mission recently noticed that it appeared confused about its location in space without going into safe mode or otherwise sounding an alarm.

 The glitch has to do with

 Voyager 1's attitude articulation and control system, or AACS, which keeps the spacecraft and its antenna in the proper orientation.

The agency says that Voyager

 personnel will continue to investigate the issue and attempt to either fix or adapt to it. 

That's a slow process,

a signal from Earth currently takes 20 hours and 33 minutes to reach Voyager 1; receiving the spacecraft's response carries the same delay.
