The spacecraft is 90,000 miles from the planet; because the axis of Uranus lies almost in the plane of its orbit, the spacecraft comes in over the pole."

From the Catalogue:
An original illustration done for Beyond Jupiter: The Worlds of Tomorrow, a joint work by Bonestell and Arthur C. Clarke. In the tradition of the 1949 work The Conquest of Space by Willy Ley, Beyond Jupiter features the artwork of Bonestell alongside the text by Clarke to describe the historic voyages of Pioneers 10 and 11, before the two spacecrafts made their trips to the outer planets.
