The first kilometre-sized space station is complete
Construction of this large-scale habitat and research facility was made possible by the International Space Elevator, built half a century previously.
This greatly reduced the cost of surface-to-orbit transportation - from tens of thousands of dollars per kilogram in the early 21st century, to less than a dollar per kilogram by the early 22nd.
Several other large-scale space stations have been appearing in Earth orbit during the last few decades - but this is the largest, and represents a new generation.
It contains an entire fusion power plant at its core, utilises a form of artificial gravity and is home to many hundreds of people and androids.
The commercial space industry is booming during this time, with a regular flow of traffic between Earth, the Moon and several near-Earth asteroids which are now being mined for raw materials
