The International Space Station (ISS) has the capability to test and demonstrate, and otherwise assist in the development and validation, of a wide range of advanced technologies. Technology tests and demonstrations for advanced communication systems, closed-loop environmental control systems, advanced power storage and generation systems, advanced electric and electromagnetic propulsion systems, and others are being assessed for inclusion in an ISS Pre-Planned Program Improvement (P3I), Technology/Improvement Roadmap. The P3I roadmap is an integrated set of technology and improvement requirements for: (1) ISS subsystem upgrades and improvements (addressing maintenance, logistics, sustainability, and enhancement functions), (2) payload hardware technology infusion, (3) ISS/Exploration technology development and tests (dual use/benefits), and (4) Engineering Research and Technology payloads. As examples of the International Space Station’s technology testbed capabilities, implementation approaches for thre...
