The Space Station structural characterization experiment

A space flight experiment being developed by NASA's Office of Aeronautics and Space Technology (OAST) that uses the Space Station as a testbed to study techniques for determining the dynamic characteristics of large space structures (LSS) is described. The experiment is separate from the Space Station Program itself with research objectives outside the domain of Space Station Program objectives. A brief description of the experiment, in terms of the general objective and approach, is given along with a statement of the potential benefits to NASA and others. The bulk of material to follow deals with the experiment definition activity that is underway. The scope of an 'initial' definition study and preliminary results from supporting Space Station dynamics analyses is presented. The term initial is used to indicate that the study currently being conducted has limited objectives and is not expected to complete the required experiment definition. A follow on study is planned and is mentioned in the summary.
