The reverse design features Mary Golda Ross writing calculations. In the background, an Atlas-Agena rocket launches into space, with an equation inscribed in its cloud. The equation, denoting the energy it takes to leave Earth and reach the orbit of a distant planet, represents her important contributions to the space program. An astronaut, symbolic of Native American astronauts, including John Herrington, conducts a spacewalk above. A group of stars in the field behind indicates outer space.
