David Starr, Space Ranger introduces the series' setting and main characters. The novel is set around A.D. 7,000 (five thousand years after the first nuclear bomb, as stated at the beginning), when humanity has founded colonies on the inner planets of the Solar System, as well as spreading to other planetary systems with separate and sometimes hostile governments. The most powerful organization in the Solar System is the Council of Science, which uses scientific expertise and intrepid field agents to counter political and military threats to Earth's government. A year has passed since the events in David Starr, Space Ranger. In that time the spaceship TSS Waltham Zachary has been taken and gutted by pirates based in the asteroid belt. Because David "Lucky" Starr harbors a personal dislike of the pirates for their murder of his parents, he has devised a plan whereby the unmanned survey ship Atlas, as soon as the pirates capture it and bring it to their hidden base, will explode. Unknown to anyone, Starr has leaked the plan to the pirates and sneaked aboard the ship, believing an infiltration will be a more efficient way to bring down the pirates. Shortly after returning from the Asteroid Belt, David "Lucky" Starr learns that his Science Academy roommate Lou Evans had been sent to investigate trouble on Venus, but the Council of Science office on Venus has requested that he be recalled and investigated for corruption. It has been a year since the events in Lucky Starr and the Oceans of Venus, and in that time a government-funded research project, Project Light, is built at the astronomical observatory on Mercury's north pole to conduct research into the newly discovered sub-etheric optics in hope of transmitting solar energy through hyperspace. The head of Project Light is the leading scientist in sub-etheric optics, Scott Mindes. A series of accidents has plagued Project Light, which David "Lucky" Starr and John Bigman Jones have come to investigate. Shortly after meeting Starr and Bigman, Mindes takes them onto the surface of Mercury and explains his worries; but works himself into a frenzy and fires a blaster at Starr, whereupon Bigman tackles him and he is brought unconscious into the observatory. For six years, Jupiter IX has been the site of a secret project to develop an antigravity, or Agrav, space drive; but the Council of Science learns that information from the project is released to the enemy Sirians. A month after returning from Mercury, protagonists David "Lucky" Starr and John Bigman Jones are sent to Jupiter IX to investigate, bringing a V-frog to aid the investigation. Six weeks after returning from the Jovian system, David "Lucky" Starr learns that Jack Dorrance, the chief of a Sirian spy ring uncovered by Starr in the Jovian system, has escaped from Earth.
