Pedantic much? In conversational English what I said is != blocks ALL light without absorbing ANY heat. Visors block enough light to greatly reduce reflected light, and do it without substantially increasing satellite temperature. There is a thing called an insulator, which I hear can efficiently reduce the transfer of heat from things like visor to satellite.
