Chapter 19 of "Pale Blue Dot" explores the concept of terraforming and human colonization of the Solar System, focusing on the possibility of transforming asteroids and planets like Mars for human habitation. It discusses early science fiction visions of space colonization, the physical and technological challenges of inhabiting small bodies such as asteroids, and the potential future use of advanced energy sources like antimatter and fusion to move and sustain these habitats. The chapter also addresses the practical and ethical considerations of planetary engineering and the gradual transition from government-led pioneering to self-sufficient extraterrestrial communities.

The chapter outlines two intertwined narratives set on Mars: one in the near future where Dr. Holland catalogs Mars' biosphere and faces tragedy after an artefact discovery disrupts the terraforming program, and another in the far future where the dying planet is embroiled in a Final War between men and spirits. The disgraced Champion Val Mora and his spirit lover are released to find the missing Librarian of Mars, the key to humanity's salvation, linking their destinies across millennia.

In this chapter, the characters complete modifications to their time-space vehicle, the Gay Deceiver, enabling it to travel between universes with multiple fail-safes and voice controls. They discuss ambitious plans to reengineer the Solar System, including terraforming Venus, moving atmospheres, and creating new Earth-like planets at Trojan points, leveraging the unique properties of their continua craft which requires no power. The dialogue reveals their cautious optimism about using advanced technology to solve planetary overcrowding and environmental degradation, while also touching on secrecy, survival, and the ethical implications of godlike planetary engineering.

In this chapter, the narrator and other consciousnesses emerge from a daughter wormhole into orbit around a new, habitable but challenging planet dubbed New Mars. Reid, a key figure, addresses the assembled minds in a virtual conference, declaring their freedom and outlining plans for terraforming, cloning, and rebuilding society while cautioning about the dangers of uncontrolled artificial intelligence. The chapter concludes with the narrator beginning work on the Stone Canal, a vital infrastructure project to bring water from comet impacts to the new city.
