A joint interview with Reuben H. Gablehouse and Fred Dolder covers the Ball Brothers contracts for the Orbiting Solar Observatory (OSO), telemetry problems, and their work on Skylab. The interview principally covers Ball Brothers' contracts for and development of the early OSOs from the late 1950s to the late 1960s. In this period Dolder served as Program Manager for OSO. Significant topics include: evolution of the original OSO proposal; the relationship of John Lindsay of Goddard (the contracting agency for OSO) with Ball Brothers; design changes relating to pointing controls, telemetry and structural configuration; loss of the AOSO contract; and Ball Brothers' work on Skylab.
