Setting

''Lucky Starr and the Big Sun of Mercury'' was written in 1955, when it was believed that Mercury was

and fires a blaster at Starr, whereupon Bigman tackles him and he is brought unconscious into the observatory. Starr and Bigman meet Mindes' friend Dr. Karl Gardoma, the observatory's physician; Jonathan Urteil, who works for a political opponent of the Council of Science named Senator Swenson; Dr. Lance Peverale, the head of the observatory; and Dr. Hanley Cook, Pevarale's chief assistant, who wants to succeed Peverale. The next day, at a banquet in Starr's honor, Peverale states his belief that the Sirians are behind the troubles plaguing Project Light; whereupon Starr replies that the Sirians' most likely locations are the abandoned mines located beneath the observatory, and proposes to search them. Speaking to Cook after dinner, Starr learns Cook's opinion Peverale has become obsessed thinking of the Sirian threat. While Bigman prepares for the trip into the mines, Starr obtains two micro-ergometers, whereby to detect

After Starr leaves, Bigman is attacked by Urteil, and both are attacked by a heat-seeking native organism. Bigman distracts the latter with Urteil's blaster, then calls the Dome for help.

When Starr returns to the dome and learns of Urteil's death, he asks to be present when Peverale conducts an official inquiry, at which Bigman reveals that it was Cook who caused Urteil's death and reveals that only Cook knew where he and Starr would be in the mines, wherefore Urteil must have gotten the information from him. Cook then admits that Urteil had blackmailed him, and was killed to save Cook's career. Starr then reveals that the robot was brought from Sirius by Peverale in hope to use it to implicate the Sirians in the sabotage of Project Light. Starr has Peverale and Cook placed under arrest, and assumes control of the Dome in the name of the Council of Science. On the return journey to Earth, Starr admits to Bigman that the present quarrel between Senator Swenson and the Council of Science was a draw, in that Jonathan Urteil was not able to manufacture any scandal against Project Light, but the two top men at the Mercury observatory were exposed as felons. Although Swenson is ruthless and dangerous, he is the sort of critic the council needs to keep it honest.

are thinly populated and they are extremely decentralized. They live in isolated individual family units, each with its own energy source and services. Each has its group of mechanical slaves — there's no other word possible — slaves in the form of positronic robots, which do the labor. The Sirian humans maintain themselves as a fighting aristocracy. Every one of them can handle a space-cruiser. They'll never rest until they can destroy the Earth . . . . :"They despise us. They consider us scarcely more than animals. The Sirians themselves are very race-conscious. Since Earthmen first colonized Sirius, they have been breeding themselves carefully until they are free of diseases and of various characteristics which they consider undesirable. :"They are of uniform appearance, while Earthmen are of all shapes, sizes, colors, varieties. The Sirians consider us inferior. That's why they won't let us emigrate to Sirius". The Sirians therefore resemble the 'Solarians' of ''The Naked Sun'', albeit less isolated and far more war-like. In ''Big Sun of Mercury'', Starr notes that :"if the Sirians are race-conscious and are breeding themselves into uniformity, they will defeat themselves in the long run. It is variety in the human race that brings about progress. It is Earth and not Sirius that is in the forefront of scientific research. Earthmen settled Sirius in the first place, and it is we, not our Sirian cousins, who are advancing in new directions every year". Also noteworthy is the fact that in ''Big Sun of Mercury'', with its references to positronic robots and the
