Space fission power systems will require extensive developmental and qualification testing prior to launch and in-space operations. This technical session will offer insight into several recent test efforts, including discussions of the test preparations, design and fabrication of test support equipment, and summaries of test results. Presenter bios: Luke Hansen is a Ph.D. student at the University of Tennessee Knoxville studying advanced fabrication techniques of thermoelectric materials for radioisotope thermoelectric generators.
