Integrated Systems and Operational Autonomy for Gateway

The Lunar Gateway space station will be operated with less human oversight and control than any human spacecraft thus far. An autonomous software control architecture has been developed to allow the spacecraft to maintain safe operations of the vehicle during times of no human involvement. The development of these autonomous control functionalities has been both technical and process driven. Given that the Gateway will be built modularly with contributions from all over the world, the systems engineering processes had to be shaped to fit with the contractual and political realities of the construction of the international lunar habitat. This paper will describe these challenges and contributions to the development of human spacecraft for sustainable deep space missions.
