Deputy Secretary Chrisjen Avasarala (Shohreh Aghdashloo) tries to avert an all-out war with Mars. The LDSS Nauvoo, a massive, 2 kilometer long (1.2 miles) 'generation ship' must be sacrificed to destroy Eros and prevent further protomolecule infection. They find that a shuttle from the Anubis had departed for Eros, so they nuke the ship and head to the asteroid. Here they discover a strange, blue alien crystalized structure that's growing around the ship's reactor, which later becomes known as the protomolecule (opens in new tab). They are sent by Johnson to investigate a derelict stealth ship called the Anubis (opens in new tab), which is suspected of destroying the Scopuli and the Canterbury. Tycho station is also home to secret headquarters for the OPA, and the Rocinante crew forms a tentative alliance with its commanding officer, Fred Johnson (Chad Coleman - Klyden from 'The Orville'). The LDSS Nauvoo (opens in new tab) is just over 2 kilometers (1.2 miles) long and half a kilometer (0.3 miles) wide. An enormous 'generation ship' is being built here for the Mormons to travel to Tau Ceti, a journey that will take them around 100 years.

The story arc of Detective Miller, played by Thomas Jane, is without a doubt one of the highlights of 'The Expanse' Season 1. They rename their ship - and change its transponder - to the Rocinante (opens in new tab) to avoid attracting attention. The four remaining Canterbury crewmembers narrowly escape to a frigate, called the Tachi, docked in the Donnager's landing bay. The Donnager is attacked by the same mysterious stealth ships. and the Martian government, the military forces of Mars are desperate to ensure collected sensor data about the mysterious stealth ships makes it back home. With tensions already at near-breaking point between the U.N. The Canterbury is then destroyed by unknown ships with stealth technology, and the Knight is rescued by the MCRN Donnager (opens in new tab), the flagship of the Martian Congressional Republic Navy's Jupiter fleet. Crew members Jim Holden (Steven Strait), Naomi Nagata (Dominique Tipper), Amos Burton (Wes Chatham) and Alex Kamal (Cas Anvar) head over to investigate in a shuttle called the Knight (opens in new tab) and find a planted distress beacon made with Mars tech, so they assume the Martians destroyed the Scopuli. The second is in deep space, aboard the ice hauler Canterbury (opens in new tab), which responds to a distress call from a ship called the Scopuli (opens in new tab). The first focuses on detective Josephus Miller (Thomas Jane), born on the dwarf planet Ceres (opens in new tab) in the asteroid belt, who is sent to find a missing young woman, Julie Mao (Florence Faivre). The complex story told in 'The Expanse' begins with many separate elements that eventually intertwine.

In the Belt, air and water are more precious than gold. Conditions on the space stations and hollowed-out asteroid colonies are a long way from ideal, and the low gravity conditions to which they have adapted mean that most can never even visit Earth, because their bodies wouldn't be able to adjust to the increase in gravity. One simple way of looking at this is that Earthers could be considered as the wealthy elite, Martians are the middle class and Belters are the working class. The Belters are a breakaway faction that has made the asteroid belt (opens in new tab) between Mars and Jupiter their home. Earth of the future has a stark reality in 'The Expanse.' New York needs a 75-foot (23 meters) coastal defense wall to protect it from sea level rise.
