Abstract
Ground based testing is a critical and costly part of component, assembly, and system verifications of large space telescopes. At such tests, however, with integral teamwork by planners, analysts, and test personnel, segments can be included to validate specific analytical parameters and algorithms at relatively low additional cost. This paper presents analytical verification and validation segments currently added to ambient and vacuum cryogenic testing of Advanced Mirror System Demonstrator (AMSD) assemblies for the Next Generation Space Telescope (NGST) project. The test segments for workmanship testing, cold survivability, and cold operation optical throughput are supplemented by segments for analytical verifications of structural, thermal, and optical parameters. Utilizing integrated modeling and separate materials testing, the paper continues with analyses to be performed for AMSD testing, currently slated for calendar year 2003. These segments form a well-verified portion of the integrated modeling being conducted on AMSD for NGST performance predictions.
