Lets assume that the NASA vacuum chamber has a
finite size, and walls possibly of glass or metal.
I've had the hairs on my arm stand up when switching
on a big TV set half a metre away. And that PSU
*wasn't* optimised for its electrostatic effect. :o)

And don't most vacuum chambers still have 1% or so
air left in them??
