Mars (Sol IV) was the fourth planet in the Sol system and the capital planet of the Confederated Martian Colonies, a Federation Member State.


Technological breakthroughs made after first contact with the Vulcans made terraforming Mars much more feasible, and warming the planet was accomplished in a fraction of the time 21st century scientists had predicted. Water and oxygen were liberated from the subterranean permafrost and genetically engineered bacteria were introduced into the terrain. This began the terraforming process. There were colonists on Mars as early as 2103, but they needed atmospheric suits in order to breathe outside a biosphere. Not quite one hundred years after that, Mars possessed a breathable atmosphere. The earliest colonists utilized local Martian resources to build habitable structures, including basaltic regolith. Refined and mixed with water, it forms a crude concrete. This process was far more efficient than trying to bring building materials from Earth. (VOY novel: Mosaic, DS9 novel: Space Camp)

In spite of undergoing the process of terraforming as early as the 22nd century, by the 24th century water covered only 10% of the surface of Mars. Most of it was concentrated in small fresh water lakes which were the result of impact craters. As of 2350 the atmosphere of Mars was fully breathable by Humans, although ultraviolet radiation from the sun still required some measure of protection before stepping out onto the surface. (Decipher RPG module: Worlds)

In 2385, the planet was rendered uninhabitable by the Attack on Mars, which ignited the atmosphere. 14 years later, the atmosphere was still burning. (PIC episode: "Remembrance")


The Core

The Core walks on Mars.

Automatic mining facilities were set up on Mars during the late 20th century utilizing DY-100 vessels. (ST reference: Federation: The First 150 Years)

Verna Mitrios was the first person from Earth to set foot on Mars. (ST - The Lost Era novel: Serpents Among the Ruins)

The first humans to walk on Mars were an international team of astronauts sometime after 2009. A crucial member of the team was The Core. (ST performance: "Star Trek Live")

One Small Step-episode

Earth's Ares IV over Mars in 2032

Mars was one of the first planets colonized by the Human race, who began their efforts in 2103. (VOY episode: "The 37's") It became the first fully established colony of United Earth. Colonization of the planet involved a primitive form of terraforming that involved Zubrin craters where each transparent nanoplastic membranes being placed around each crater on the surface whereupon an alteration of each few thousand hectares of lands biosphere. Thus, an attempt was made to terraform the world; one crater at a time. To oversee the development process of Mars surface, Earth awarded a license to a business body known as the Consortium that handled the terraforming and development of the planet. (TOS novel: Preserver)

In the purges that followed the Eugenics Wars, many of the offspring of Khan Noonien Singh's augmented followers secretly resettled areas like Mars, Alaska, Luna, and the Sahara Reclamation Zone, where life was hard enough to ensure few people asked probing questions. (TNG novel: Infiltrator)

Among those that migrated to Mars included the southwestern Native American tribes who refused to surrender their sovereignty to the United Earth government. These groups formed their own tribal nations on Mars such as the Hopi-Pueblo who settled on the planet by 2109. (ENT - The Romulan War novel: Beneath the Raptor's Wing)

Within just a few years, however, a general uprising known as the War of Martian Independence occurred in support of Martian sovereignty (ENT - The Romulan War novel: Beneath the Raptor's Wing) The incident brought about the destruction of Gundersdotter's Dome and the assassination of Rayla Gundersdotter by Consortium militiamen with the business organization having its license revoked. (TOS novel: Preserver) This movement culminated with the drafting of the Fundamental Declarations of the Martian Colonies, which became one of the most important documents addressing individual rights in Federation history (TOS episode: "Court Martial") and in the independence of the Martian colonies and establishment of the Confederated Martian Colonies with the Assembly of the Martian Colonies being its ruling body. Despite this being the case, the Martian Colonies became little more than a political satelite of the United Earth government and was considered less important compared to Alpha Centauri III and Earth which had much larger populations on their surface. (ENT - The Romulan War novel: Beneath the Raptor's Wing)

A council of religious scholars on Mars came up with Local Planetary Time, which was based on Vulcan look-up tables and charts that Vulcan ships had been using to keep their time that of Vulcan. (DS9 - Millennium novel: The War of the Prophets)

Verteron array

The Verteron array fires.

In 2155, Mars was the site of the Verteron Array, a powerful device designed to keep asteroids and other planetoids away from Earth and other important locales in the Sol System. That year, the anti-alien terrorist group known as Terra Prime attempted to hijack the array to destroy the headquarters complex of the United Earth Starfleet in order to force all non-Humans out of the Sol System. The attempt failed with the intervention of the crew of Enterprise (NX-01). (ENT episodes: "Demons", "Terra Prime") As part of Humans' colonization efforts, Mars was in the process of being terraformed in the mid-22nd century, by redirecting comets to impact the planet and release their frozen gases into the thin Martian atmosphere. (ENT episode: "Terra Prime") In the early stages of the Earth-Romulan War, there were many fears that the Romulan Star Empire would strike at Mars. (ENT - The Romulan War novel: Beneath the Raptor's Wing)

Mars was the location of the city of Utopia Planitia, and Starfleet's Utopia Planitia Fleet Yards. (VOY episode: "The 37's"; TNG episode: "Encounter at Farpoint", DS9 episode: "Emissary") In 2161, the Confederated Martian Colonies became one of the first states to join the United Federation of Planets after its founding. (ST reference: Star Charts.) Beginning on reference stardate 1/9010, the Mars shipyards were a major contributor of ships to the growing numbers of Loknar-class frigates entering service. (FASA RPG module: Federation Ship Recognition Manual)

The Martian Federation Councillor was among those being briefed about the Genesis Device in 2286. (TNG novel: The Genesis Wave, Book 1) In 2376, Mars was listed as the host location of a current or past marathon. (New Worlds, New Civilizations short story: "The Footfalls of Tradition")

As of 2378, Mars' population 133.8 million. However, in the early 2380s, another figure gave it as in the hundreds of thousands. (ST reference: Star Charts; Decipher RPG module: Worlds)

In 2385, during the Attack on Mars, the colonies and Utopia Planitia Fleet Yards were destroyed, killing 92,143 and igniting the atmosphere, which was still burning by 2399. (PIC episode: "Maps and Legends")

In fiction[]

In the literature of the 20th century science fiction series The Adventures of Captain Proton, Mars was known to Earth children for its canals and sandstorms, as well as for having a race of "stone-eaters". (ST - Captain Proton: Defender of the Earth short story: "The Planets of the Future")

In the year 2000, the Martian governor was found dead holding a mysterious note in his hand that had alien writing on it. (The Adventures of Captain Proton episode: "A Hero Falls")

Later that year, Dr. Chaotica raided the Space Laboratory on Mars to acquire the final component of his mind control ray, the amplitude modulator. Once it was in place, Chaotica fired the ray at ace reporter Buster Kincaid, then ordered him to kill Captain Proton. (VOY - Star Trek: Explorer short story: "Kill Captain Proton!")



The Last Unicorn RPG The Dominion War Sourcebook: The Fires of Armageddon, published by Last Unicorn Games after they had lost their Star Trek licence, states that prior to the Breen attack on Earth in late-2375, the Breen fleet attacked the Mars Defense Perimeter.
