Paper Abstract

The performance requirements for long life, high-resolution ultraviolet and visible wavelength remote-sensing spacecraft instruments are very stringent with respect to dimensional stability. For example, full focus budges for instruments such as the Jet Propulsion Laboratory (JPL) CRAF/Cassini spacecraft imaging science subsystem and the California Institute of Technology/JPL Mars Observer Camera are in the range of 0.1 micrometers per centimeter of focal length. Advanced materials having low density, high specific strength and stiffness, and good dimensional stability offer design flexibility and new opportunities to develop more sophisticated remote sensing instruments. This paper reports a study to evaluate the dimensional stability of two classes of low-density, high specific strength metal matrix composites and an aluminum-lithium-magnesium metal alloy.
