Spacecraft construction in Low Earth Orbit (LEO) remains largely untested, with most spacecraft and ISS modules fabricated on Earth before launch. Current experience is limited primarily to the assembly of the International Space Station (ISS) and some experimental manufacturing efforts. However, there are studies available, such as "Building Large Space Bases in Low Earth Orbit," which explore the potential for LEO construction. Additional resources can be found at the American Institute of Aeronautics and Astronautics (AIAA) website. Overall, while theoretical discussions exist, practical implementation of spacecraft construction in LEO is still in its infancy.
