In this work, we use several control-theoretic approaches to analyze the conditions under which manufacturing in space could take advantage of computations on earth. In one case, we utilize predictions of the process state both as the measurements reach the earth and as the control actions return to space to compute control actions. In another, we send a set of control actions back to the space manufacturing system and clarify what range of state measurements should lead the controller to select one of the control actions. We consider conditions under which doing this constant communication is an improvement to storing some set of control action-state measurement pairs in the space manufacturing system. We also discuss data privacy issues by discussing concepts which exist for securing Cloud computation (e.g., homomorphic encryption [4, 5]) or where redundancy might be used to aid in attempting to confuse an attacker.
