Project Zodiac

Project Zodiac is a space settlement project based on the visionary work of Dr. Gerard K. O'Neill (1927-1992). The early stations were designed after mid-20th-century concepts for Stanford Torus rotating wheel space stations. In the 21st century, the stations have gradually become smaller versions of O'Neill's proposed rotating cylinder space stations. The stations are located between the Earth and Luna at the L4 and L5 points. There will be thirty-six of them when they are all completed by the 2030s. Upon completion, this project would have taken almost fifty years to complete and will be home to 3.3 million people. Eventually, the population is expected to swell and stabilize to around 5 million people in total. The early stations could house 10,000 residents, while the smaller O'Neill cylinders have been proposed to house 100,000 residents per station. 
The total population of the settlement clusters is currently 2,430,000 people.
