Variable configuration spacecraft system and method for non-cooperative target capture

The invention provides a variable configuration spacecraft system and method for non-cooperative target capture, and belongs to the field of deep space exploration, and the method comprises the following steps: 1) a rigid body assembly flies to the vicinity of a target; (2) the combination body spins and unfolds to form an annular belt; (3) enveloping a target outside the annular belt; and 4) encircling the target by the girdle. Large space debris and small celestial bodies belong to non-cooperative targets, a special interface for assisting capture cannot be provided, a general control mechanism and method are developed to realize reliable capture and stable connection of various targets, and the difficulty is great. In order to solve the problem, a plurality of controllable satellites which are connected into length-controllable ropes are unfolded to form an annular multi-body tethered satellite formation system, and the annular multi-body tethered satellite formation system captures non-cooperative targets
