A method for effecting solar radiation in space prior to the solar radiation reaching Earth. The method includes the steps of choosing a location between the Earth and the sun, focusing reflected solar radiation from two reflectors upon the location, monitoring solar radiation that passes through the focal location, and adjusting the reflectors to increase the size or change the shape of the focal location. The disclosure further includes a structure having a single joint for articulating the structure, where the single joint rotates the structure about a first axis in response to a first input and where the single joint rotates the structure about a second axis in response to a second input.
