The Expanse is perhaps one of the most fascinating science fiction TV shows in recent memory. Based on the series of books by James S. A. Corey, it takes place in the 24th century, when humanity has expanded throughout the solar system. Earth and its moon operate under the United Nations of Earth and Luna, while Mars is an independent colony. Meanwhile, the Belters, residents of the Asteroid Belt and moons of the outer planets, fight for survival in harsh conditions.
