Editors Reads Verdict
The middle volume of the Mars trilogy deepens everything that made Red Mars extraordinary — the science, the politics, the characters — and earns its own Hugo Award by creating an argument about terraforming that is genuinely philosophically sophisticated.
What We Loved
- The terraforming debate between Greens (full transformation) and Reds (Martian ecology preserved) is one of SF's most serious environmental arguments
- Robinson's Mars remains the most fully realized planetary environment in science fiction
- The multigenerational scope — children of the First Hundred are now adults shaping the debate — gives the trilogy real narrative momentum
Minor Drawbacks
- The pace is deliberately slow — this is the middle volume of a trilogy that rewards patient readers
- New readers who haven't read Red Mars will lack essential context for the characters and their histories
Key Takeaways
- → Planetary terraforming raises the same ethical questions as all large-scale environmental transformation: who decides, who benefits, what is lost?
- → Political change happens through the accumulation of small acts of resistance and negotiation, not through revolutionary rupture
- → The relationship between a people and their environment is always also a relationship between a people and their values

Green Mars Review
Green Mars is the second volume of Kim Stanley Robinson’s Mars trilogy, winner of the Hugo Award for Best Novel in 1994, and the book in which the series’ true subject becomes fully apparent. Where Red Mars focused on the arrival and early terraforming work of the First Hundred, Green Mars surveys the generational aftermath: decades have passed, the planet is slowly changing, and the political and philosophical debate about what Mars should become has intensified into something approaching civil war.
The novel’s central conflict — between the Greens who want to transform Mars into a habitable world with atmosphere and running water, and the Reds who want to preserve the planet’s original ecology (such as it is) for its own sake — is Robinson’s most explicit treatment of the environmental ethics that run through all his work. The debate is genuine and the characters on both sides are given compelling arguments. Ann Clayborne, the most prominent Red, is not a villain but a scientist with a coherent vision of what Mars is and what its terraformation would destroy; her opponents are not simply progress-minded despoilers but people who also love the planet they want to transform.
Robinson’s Mars is the most fully imagined planetary environment in all of science fiction — not just geologically and atmospherically detailed but politically and culturally alive, with distinct communities, ideologies, and economies that have evolved out of the specific conditions of the Martian surface. Green Mars advances this world with the same seriousness and ambition as its predecessor, and earns its place as one of the finest middle volumes in science fiction trilogy history.
