• Agentic RL: Focuses on active selection and utilization of external tools, such as reasoning modules or data fetchers, to enhance multi-step reasoning over extended timescales. This approach is pivotal in developing autonomous problem-solving agents that can self-discover and leverage resources as needed.

These methods foster agents that can self-direct learning, discover new tools, and operate independently over years, aligning with the demands of remote space missions and complex infrastructure management.
