Mission extension refers to the concept of extending the operational lifespan of spacecraft or satellites beyond their originally planned mission duration. This can involve implementing new technologies, strategies, or alternative uses for the spacecraft in order to continue gathering valuable data or performing specific tasks. Mission extension research focuses on developing innovative approaches to prolong the useful life of space assets, optimize their performance, and maximize their overall impact on scientific research, communications, or other applications. This area of research plays a crucial role in maximizing the return on investment in space missions and advancing our understanding of the universe.
