And neither are spacecraft antennas no matter what the type.


The Earth is in space and the spacecraft also.


The earth and spacecraft are floating around in a vacuum, same as
between your ears. I think you'll find it rather difficult to
demonstrate a conduction path through a vacuum for your grounded
antenna theory. Besides, if outer space did provide a conduction
path, it would also short out the antenna elements.

The same is with aircrafts and autos.


Aircraft and autos do not operate in outer space.

All transmitters and receivers are connected with the mass.


What mass of outer space? There is roughly 1 hydrogen atom per cubic
centimeter in outer space. That's not much mass and certainly not
enough to ionize and produce a conductive path.
