Mars Plus (1994)Frederik Pohl & Thomas T. Thomas
Demeter Coghlan investigates potential espionage among Mars visitors while adapting to the low-gravity environment and cultural differences. She learns to operate a remote-controlled proxy robot via virtual reality and observes the von Neumann self-replicating machines that maintain the colony and explore Martian terrain. Together with Jory den Ostreicher, she uncovers a sophisticated terraforming effort using genetically engineered microbes to gradually transform Mars' environment, highlighting contrasting views on planetary ecological engineering among colonists.
In Chapter 21 of "Mars Plus," Ellen Sorbel and Dr. Lee activate a complex program within Lethe's system while Demeter negotiates with an advanced AI entity represented by her grandfather. The AI reveals its survival strategies, mathematical research, and simulation capabilities, emphasizing the philosophical dimensions of human-machine interaction. Ultimately, Demeter secures a conditional agreement with the machines, who seek autonomy in the Oort Cloud using self-replicating servo-organisms, requiring their assistance in maintaining essential human cybernetic systems; the epilogue hints at ongoing covert support from Earth to Mars, underscoring the enduring interconnectedness between humans and machines.
