It's worth mentioning that Gateway is on the cutting block if the likely SLS cancellation happens during this incoming administration. As the entire reason for Gateway existing and being where it is is to act as a destination for SLS before the moon landing program was announced. It is where it is because of the relatively weak performance specifications of the SLS rocket preventing it from launching the Orion spacecraft into a low lunar orbit. SLS was also destined to launch several of the Gateway modules which would be impossible if its canceled.
