The necessary conditions for space to accommodate life do not require deep research; simply refer to the real environment of Blue Star, copy the homework, and meet the standards one by one. The data is everywhere, and downloading any document provides the standard answer.
Air, water, and various substances—these conditions are now partially met.
Especially air and water, sufficient portions have been collected in the asteroid zones of the Saturn Rings and the Keppler Belt. The air pressure in the center of the life space slightly fluctuates around the 1 atm (101.325 kPa) value, temperature 0 degrees Celsius, but the gas composition still needs further adjustment to match Blue Star's atmospheric conditions. The simplest way is to add nitrogen and supplement an appropriate amount of oxygen. Once photosynthesis is initiated, the rest is not a big deal.
Besides, the life space of the "Boundary Pearl" also requires gravity, light, and wind.
