What is NASA ISAM State of Play 2025?

NASA's ISAM State of Play is a periodically issued reference document surveying government, industry, and academic capabilities in In-Space Servicing, Assembly, and Manufacturing, the set of technologies that let spacecraft be repaired, refueled, assembled, or built while already in orbit. The document catalogs ISAM projects and technical approaches across the field to give mission planners and engineers a shared picture of what capabilities exist and how they might be combined into future space architectures.
