AB: NASA's Space Technology 8 project (ST-8) is subsystem demonstration which will validate four technologies that have been identified as necessary to enable future NASA space science missions. NASA's New Millennium Program, with input from the science community, identified the following four technologies: Miniature Loop Heat Pipe with Multiple Evaporators Thermal Management System (MLHP), Scalable Architecture for the Investigation of the Load Managing Attributes of a Slender Truss (SAILMAST), Next Generation UltraFlex (NGU), and Environmentally Adaptive Fault Tolerant Computing (EAFTC). Once validated on a deep space mission, these technologies will be available for use on future science missions. Examples of previous enabling technologies demonstrated by NMP are the ion engines on Deep Space 1 and the Autonomous Sciencecraft Experiment demonstrated by ST6. The MLHP, provided by NASA's Goddard Space Flight Center will demonstrate that a loop heat pipe with multiple evaporators and condensers can transport large heat loads over long distances without external pumping. It is expected that this technology will enable more precise temperature control decreasing the mass, power, and volume of small remote sensing and surface-based spacecraft. The SAILMAST experiment is a deployable gossamer mast technology, which will validate its load-carrying characteristics by correlating in-flight measurements with analytical predictions. It will enable a new class of missions, which employ solar sail propulsion technology. The NGU will demonstrate the next generation in ultra-lightweight fan-folded flexible solar arrays, providing ultra-high specific power (170-220 W/kg BOL), ultra-compact stowage volume (>33 W/m3), and high deployed stiffness. The result is less mass and volume needed for power generation on future spacecraft. The EAFTC will integrate commercial-off-the-shelf (COTS) processing components and fault-tolerant control algorithms to provide an adaptable, high-performance, on-board science processing platform. It is expected that this experiment will enable more capable, high performance, fault-tolerant, processing to handle, in a variety of planetary and deep space environments, the large science and autonomy data processing loads expected in the future. This work performed at JPL/Caltech under contract with NASA.
