Management of mass budgets and the associated risks in the aerospace industry has positive impacts that affect delivery and launch of spacecraft. This paper presents a novel feedback control method to manage mass risk over the course of spacecraft design and production. The control method uses a dynamic upper and lower boundary formed as a function of heritage spacecraft mass risk. Spacecraft that deviate above the upper bound fall out of compliance and should trigger action. By observing how the risk mass varies over time with respect to the boundaries, scheduling risks could be identified preserving launch date and potentially acting as a cost saving effort for the spacecraft manufacturer.
