The impact on spacecraft design and technology of service life requirements of 15 yr in geostationary and 10 yr in low Earth orbit are summarized. Factors which limit service life are reviewed. The effects of improved technology, onboard computers and in space servicing are discussed. Control of the exposed area of spacecraft radiators to meet instantaneous requirements is suggested. Analysis of parameters which affect battery performance, annealing of solar arrays, and management of thermal control and other subsystems are considered.
