Side 1
A ring of humanity suspended in the void, where peace is measured in kilometers of steel.
Side 1 is one of the major space colonies—collectively known as the Sides—orbiting Earth in the Universal Century timeline of the Mobile Suit Gundam franchise. Built by the Earth Federation as part of its ambitious space colonization program, Side 1 serves as a large residential and commercial habitat housing millions of Spacetiers, the citizens who chose to live off-world. It is one of a numbered series of Sides that form the backbone of humanity's presence in cislunar space.
While Side 7, the industrial mining colony, is the stage for the original 0079 conflict, Side 1 and its sister colonies represent the broader civilian infrastructure that both the Federation and Zeon fought to control or destroy during the One Year War. For fans, the Sides embody the political and social tensions—between Earth and space, between nations and colonists—that drive the Gundam narrative beyond mere mecha combat.

Lore & Background
The Sides were the crown achievement of Earth's space colonization drive: massive artificial habitats, often described as elongated cylinders or ring structures spanning tens of kilometers, anchored in stable orbits around the planet. Side 1, as one of the earliest and most populous of these colonies, became a symbol of the Spaceties' growing identity. Its residents—engineers, merchants, families, students—lived in a self-contained society with its own water recycling, agriculture bays, commercial districts, and transit networks, all under the nominal authority of the Earth Federation government.
The political reality was more fragile than the Federation's propaganda suggested. Spacetiers resented their dependence on Earth for heavy industry, raw materials, and political representation. This simmering grievance was exploited by the Zeon Principality, whose founding leader, Zabi, framed the One Year War in terms of Spaceties' liberation from Earth's economic stranglehold. For the citizens of Side 1, the war meant something very concrete: the sudden appearance of Zeon mobile suits in orbit, the evacuation of families into underground shelters, and the long, anxious silence of air-raid sirens echoing through the colony's corridors.
In the broader Gundam mythology, Side 1 and the other Sides represent the civilian cost of superpower conflict. They are not battlefields in the traditional sense—there is no terrain to contest—but their destruction or capture would be an existential blow to millions. The Federation's strategy of defending the Sides with space fleets, and Zeon's strategy of threatening them to force Earth's hand, gives the colonies a strategic weight that shapes every major engagement in the 0079 war.
In Their Own Story
The afternoon shift ended with the soft chime of the mag-rail doors. Kael pulled his work gloves off and stepped into the transit tube, the recycled air carrying the faint metallic tang that never fully left Side 1 no matter how many times the filtration systems cycled. Around him, commuters in their faded Federation-issue jackets murmured about the news feed—another Zeon probe detected beyond the Apsis line, another week of rationed power in the eastern residential ring.
He pressed his palm to the window panel. Below, Earth hung in the black, blue and white and impossibly close. Three years he'd lived in orbit and the planet still looked like something from a storybook, something you weren't allowed to touch. A child beside him pointed and said, "Mama, is that where the other people live?" Her mother smiled the careful, practiced smile of a Spaceties parent and said, "Yes, sweetheart. Far away."
Kael didn't correct her. Far away was the only way to keep the peace. The mag-rail hummed, the colony's vast spine groaned with the weight of two million lives, and the stars outside the viewport went on burning, indifferent to the war being negotiated in the corridors of power ten thousand kilometers below.
Reader's Guide
Side 1 sits in a stable low-to-mid Earth orbit, one of several numbered Sides that form a loose constellation of habitats around the planet. It is not a single structure but a complex of interconnected cylindrical and ring-shaped modules, each housing residential blocks, agricultural bays, commercial strips, and industrial workshops. The colony is governed locally by a colonial council that answers, in theory, to the Earth Federation's central government in Tokyo. In practice, the distance and the political friction between Spacetiers and Earthnoids make governance slow and contentious.
Daily life is defined by the constraints of a closed ecosystem. Water is recycled endlessly. Food comes from hydroponic farms in the colony's agricultural rings. Power is generated by solar arrays and, in the Universal Century, by fusion reactors that make the Sides both self-sufficient and strategically vulnerable. The mag-rail transit system connects the colony's modules, and the constant low hum of life-support machinery is the background music of every conversation.
The One Year War transforms Side 1 from a quiet residential world into a strategic asset. The Federation stations space fleets in the vicinity to protect the colony, while Zeon's long-range mobile suit units make the Sides a perpetual target. Residents learn to read the sky for the glint of enemy hulls. Evacuation drills become routine. The colony's economy shifts toward wartime production, and the political gap between Spacetiers and Earthnoids widens with every headline. Side 1 endures, but its people carry the weight of a war that is, at its core, a fight over who gets to live in space and who gets to tell them they can't.
Did You Know?
- The Sides, including Side 1, are part of a broader space colonization program by the Earth Federation, and they are distinct from other types of space settlements like industrial mining colonies such as Side 7.
- The political tension between Spacetiers (space-dwelling citizens) and Earthnoids (Earth-based citizens) is a central theme of the Universal Century Gundam stories, and the Sides are the physical heart of that divide.
- In the original Mobile Suit Gundam (U.C. 0079), the One Year War pits the Earth Federation against the Zeon Principality, and the Sides are both a strategic prize and a humanitarian concern throughout the conflict.
- The Sides are depicted as enormous artificial structures—often tens of kilometers in length—making them among the largest human-made objects in the Gundam universe.
