the mass will never change. the only thing that changes is weight. but mass is constant

Same thing...mass is invarient to location in the universe. That is, the mass is .15 kg anywhere, including the Moon and the Earth.
Weight, the force of gravity, is what changes according to where the mass is located wrt the source of the gravitation force. For example, the gravitational force from the Moon is about 1/6 that of Earth. So, when on the Moon, your .15 kg rock would weigh 1/6 as much as on the Earth.
