ATHENA is a second Large-class mission selected by ESA in Cosmic Vision plan, with a launch foreseen in 2028. Polish scientists and engineers participate in the design and construction of the Wide Field Imager (WFI) – one of two instruments onboard of the ATHENA mission. We are responsible for the Filter Wheel Assembly (FWA) with its controller and the Power Distribution Unit (PDU). FWA is an opto-mechanical system for filter changing situated in front of the sensor, and in addition used for calibration of the whole instrument. PDU will be used to distribute power into the given instrument components. We present the preliminary design of both satellite components, which are discussed with WFI consortium.
