The focus of this analysis is on the difficult, yet critical, step of preparing derelicts for removal from orbit by grappling and de-tumbling the object. If the objects are made stable (i.e. not tumbling) and have a common attachment point, then the active debris removal process by another system can be enabled. The approach of this study is to identify possible applications for a microsatellite (less than 100 kg) to detumble large derelict objects as a precursor to active debris removal. This satellite size is small enough to deploy many of them into an orbital regime from a single launch, but large enough to create a reasonable physical effect on a derelict. Two mechanisms investigated to reduce the tumble rate are applying a retarding torque and/or increasing the moment of inertia. Three potential solutions in each of these two general categories are investigated in detail.
