The Mars trilogy is a series of award-winning science fiction novels by Kim Stanley Robinson that chronicles the settlement and terraforming of the planet Mars through the intensely personal and detailed viewpoints of a wide variety of characters spanning almost two centuries. Ultimately more utopian than dystopian, the story focuses on egalitarian, sociological, and scientific advances made on Mars, while Earth suffers from overpopulation and ecological disaster.
The three novels are Red Mars (1993), Green Mars (1994), and Blue Mars (1996). The Martians (1999) is a collection of short stories set in the same fictional universe. The main trilogy won a number of prestigious awards. Icehenge (1984), Robinson's first novel about Mars, is not set in this universe but deals with similar themes and plot elements. The trilogy shares some similarites with Robinson's more recent novel 2312 (2012), for instance, the terraforming of Mars and the extreme longevity of the characters in both novels.
