Mass remains constant regardless of location because it is a measure of the amount of matter in an object. Weight, however, depends on the gravitational force acting on that mass. Since the Moon's gravitational force is weaker than Earth's, an astronaut's weight would be less on the Moon, but their mass would stay the same.
