Voyager and Explorer Sensors Timeline

How long can the sensors record on internal memory? I have been able to retrieve the recorded data, but just wonder how long I can expect to record data for two or three points.

I believe it is all about how many data points and not about how much time. 30,000 seems to stick out to me, but you would want to look at the documentation for the exact number.

Yes, 30,000 data points is approximately what the data can hold. It depends on which sensors you use though. If you are looking to record using either the accelerometer, the gyrocsope, or the magnetometer, those are going to take up the most memory as they are all actually combined as one sensor/IMU and they record three values at every point. You will get around 30,000 data points with those sensors. You can probably get more though with just the light sensor, because you can record data with it independently of other sensors, and because it only has one value for every point recorded. 

Let me know if that clarifies things.

Thanks so much,
