Gateway will be smaller than the International Space Station. . . . Gateway will have five modules. One or two of them, each about the size of a school bus, will house astronauts. Another module will provide solar electric power, for propulsion. Others will serve as an air lock for spacewalking astronauts and a docking port for vehicles. Astronauts will travel to the moon’s surface and back in a smaller, reusable craft.
