The ability to build large structures in space will play a key role in the future space utilization. Large solar power harvesting systems, telescopes, and even orbital sunshades will shape the evolution of the humankind in the next decades. To overcome the limitations imposed by the volume and mass available from the launchers, such structures will need to be launched as standalone systems assembling directly in space. Hence, modular, scalable, reconfigurable and autonomous architectures are being developed as enabling technologies by many actors in the space business. MOSAICO (MOdular and Scalable space platform for the AutomatIC in-Orbit assembly) is an innovative concept of a modular and reconfigurable space platform, capable of evolving in configuration, shape, and size, to create a large-scale orbiting system.
