Space satellites are invisible instruments of globalization that influence governmental policies. This paper examines remote sensing satellites as optical devices capable of redefining human cognition. They represent accessibility and opennesss through the more agreeable pardigm of transparency. However, transparency, like surveillance, is based on the interconnection between power, knowledge and perceptual experience. Artists use a variety of tactical practices, including amateurism, to tease apart these connections. Amateurism dedicates itself to the politics of knowledge. The author concludes, based on examples of her work and that of others, that the potential for political intervention exists when knowledge is paired with action.
