The invention discloses an in-situ resource conversion and food structure generation system for an extreme physical environment, belongs to the technical field of intersection of extreme environmental engineering and food engineering, and aims to solve the problems that food supply depends on external transportation for a long time and the anti-risk capability of a traditional agricultural system is insufficient in the extreme physical environment. The system comprises a resource acquisition module, a resource conversion module, a food structure generation module and a system operation control module. The system generates food base components by obtaining environmental in-situ resources, using biotransformation links, non-biotransformation links, or a combination thereof, and using physical conditions in an extreme environment as processing boundary conditions to perform structured, conformal, or ingestible treatment on the food base components or biological products, such that the food base components or biological products are obtained. And a structured food for human ingestion is generated. The system operation control module dynamically adjusts operation parameters according to a resource state, an energy state or a module operation state, triggers a degradation operation strategy under an abnormal or limited working condition, and preferentially maintains continuous supply of basic food. According to the invention, long-term operation can be realized without external continuous material supply, and the system is suitable for non-earth or non-earth-like extreme physical environments.
