Grounding Electronics in Space: A Question to Ponder

[Maxwell]

Here is a question I ponder sometimes: Does anyone know how they ground electronics in space? I was thinking that they might use a virtual ground. Does anyone know how it is done, for sure?

I don't know anything 'for sure', but wouldn't a normal common ground be used the same as in any battery-operated circuit?

The chassis of the space vehicle is grounded, just like a chassis of a car.

On Earth we usually ground things to Earth as Earth is a giant conductor like a chassis of a car.

And since your feet are touching Earth they are grounded, so when you operate a device grounded to Earth you won't get a shock or introduce a big potential difference that can destroy the device just by touching it.

I see. Thank you for the answers.
