G-S began as a factory habitat building solar power arrays. The first habitation modules of Glaser Station were placed into a mid-altitude orbit in 2032, and the Sarkisyan complex was attached three years later. SPS construction proved to one of the most lucrative of the freefall industries and as the scale of the operation grew the permanent population of Glaser-Sarkisyan grew with it. The station was soon large enough to be almost self-sufficient and the G-S habitats became the first to declare their nationhood in the last years of the 21st century. In the decades following independence, Glaser-Sarkisyan became completely dominated by Mitsubishi and Nexant.
As the oldest continuously inhabited orbital city, Glaser-Sarkisyan has long been a major centre of Orbital culture. The city accreted habitats, factories and docks, growing into a chaotic, bustling metropolis. Following the destruction of the Artsutanov terminal it became the most populous Cis-Lunar city, and it played a key part in the region's recovery programme during the Terran Collapse.
As Earth rebuilt in the aftermath of Shiva, the beanstalk terminals became ever more important to Cis-Lunar trade, and Glaser-Sarkisyan's importance went into decline. The city responded by reinventing itself as a financial and data-commerce node, and spending its reserves of old industrial money on a new axis of spacious habitation rings to attract corporates. These investments achieved their desired ends, and many of the space-based corporations have moved their headquarters to G-S. Glaser-Sarkisyan's Alpha Ring has become one of the most prestigious areas of real estate in Cis-Luna: 'the Orbital Hong Kong'.
