Spacecraft have been troubled by thermally induced vibrations of deployable appendages for over 25 years. Thermally induced vibrations are an oscillatory structural response resulting from rapid uneven solar heating. These structural disturbances reduce the pointing accuracy of a spacecraft and in extreme cases may affect the stability of the entire vehicle. Examples of recent spacecraft whose performance has been degraded by thermally induced structural disturbances are the Hubble Space Telescope (HST), the Upper Atmosphere Research Satellite (UARS), and the Ulysses spacecraft. Current investigations of this potentially debilitating phenomena involve analytical, computational, and experimental research focused on non-spinning and spinning spacecraft booms and deployable solar array structures.
