NASA will return to the moon by 2023 and start the construction of a moon base. The base is currently called “The Gateway” to signify its status as a gateway to the rest of the solar system. It will consist of four parts: power and propulsion, habitation and utility, logistics and robot arm, and an airlock. The power and propulsion module is already under construction in facilities across the US.
