The development of a technology that could generate a hot hydrogen heat source would directly benefit the NASA manned mission to Mars by creating a capability to create a source for heating hydrogen to simulate NTP engine exhaust that could enable non-nuclear rocket engine testing in a ground testing environment. Non-nuclear testing can be used to augment and facilitate system design and development as well as reduce the potential risks and costs associated with any actual future nuclear testing, system design and development. Developing a hot hydrogen heat source capability would directly benefit NASA unfunded missions and planned missions by providing a mechanism to create a non-nuclear heat source for heating hydrogen to simulate NTP engine exhaust during ground testing. This will aid in the development of NNTP test facilities that would enable SSC to support ongoing NTP technology development at NASA/Marshall Space Flight Center and NASA/Glenn Research Center associated with the Nuclear Cryogenic Propulsion Stage (NCPS) funded through the NASA Advance Exploration Systems (AES) program, (involved in pioneering new approaches for rapidly developing prototype systems) which are being conducted in preparation for future planned manned missions to Mars. Benefits to the commercial space industry would be similar to those that benefit NASA. As commercial space based industry development continues, capabilities to further advance the safest, most cost effective means to travel into and through space are required. Utilizing novel testing capabilities developed by NASA can help facilitate these developments. Benefits to other government agencies would be similar to those that benefit NASA. By enabling a non-nuclear method to simulate nuclear rocket engine testing, capabilities that affect design, development and system operation where nuclear exhaust is generated could be used by the Army, Navy, Department of Energy (DOE), Nuclear Regulatory Committee (NRC) and Idaho National Labs (INL).
