The Heart of Gold enters orbit around Magrathea, a near-mythical dead planet once famed for its singular industry: the construction of custom-designed planets. When automatic defense systems warn the ship off and Zaphod insists on approaching for a landing, a vicious attack ensues. Arthur suggests firing the Infinite Improbability Drive at the last minute, which not only whisks the ship away to safety, but also does away with the nuclear missiles from Magrathea. The Heart of Gold lands, and Zaphod, Ford and Trillian go off to explore as Arthur and Marvin guard the ship (despite Zaphod’s assurances that the entire planet is unpopulated). Arthur soon finds out that the planet is populated by at least one man, Slartibartfast. The others soon find out that they haven’t seen the last of the automatic defense systems, and Arthur subsequently discovers that he hasn’t seen the last of his home planet.
