despun antenna is used in spin stabilization of cylindrical shaped satellite in which this abtenna is mounted on the top of the cylindrical satellite and the cylindrical body of the satellite keeps spinning around its vertical axis while the despun antenna on the body keeps following the specific area on the surface of the earth.

Most will say it has (mass*velocity^2)/2 but this is wrong. Despite the overwhelming response that i may receive here saying I am wrong, the truth is that the moon as ZERO rotational energy.

The moon has either never spun around itself, meaning the moon was thrown off (originating) from earth, or the moon did rotate long ago and has since been completely despun by the popular tidal braking theory. Those saying that the moon rotates at a period equal to its orbital period are mistaken, That is merely an illusion of rotation created by the curvature of space time by gravity in a orbital revolution.
