The invention provides a heuristic spacecraft task planning method based on a time sequence road sign, and the method comprises the steps: carrying out the knowledge modeling of a spacecraft system, and describing the constitution, resources, subsystem functions and constraint conditions needing to be satisfied of a spacecraft according to the four factors of a spacecraft structure, a task demand, an equipment state and the capability of the spacecraft; establishing a state time sequence diagram which is used for describing a time sequence relationship among internal states of each subsystem in the spacecraft; wherein the nodes represent the internal state and state time information of each subsystem, and a time sequence road sign set is calculated by establishing a state time sequence diagram; planning space search is selected as a basic search strategy, heuristic information is constructed according to the constraint condition and the time sequence road sign, a planning search direction is guided according to a heuristic sorting result, and a final heuristic task planning solving result based on the time sequence road sign is output; and outputting the task planning sequence of the spacecraft.
