Voyager 1 continues to function nicely, regardless of its superior age and 14.5 billion-mile distance (23.3 billion kilometers) from Earth. And it could obtain and execute instructions despatched from NASA, in addition to collect and ship again science knowledge.
However the readouts from the perspective articulation and management system, which management the spacecraft’s orientation in house, do not match up with what Voyager is definitely doing.
The perspective articulation and management system, or AACS, ensures that the probe’s high-gain antenna stays pointed at Earth so Voyager can ship knowledge again to NASA.
Resulting from Voyager’s interstellar location, it takes mild 20 hours and 33 minutes to journey a technique, so the decision and response of 1 message between NASA and Voyager takes two days.
