Recently, a robot independently completed the assembly of a space structure in orbit for the first time, without astronaut assistance, using an automated robotic arm to pick up parts and splice together truss modules. The system, developed by the relevant team, is part of the NOM4D program and has been operating in orbit for six months to carry out verification tests. Although the construction of the full antenna was not completed due to technical faults and time constraints, the successful assembly of the first structural segment has proven the feasibility of the on-orbit construction approach. Once the technology matures, it will change the way large spacecraft and scientific exploration instruments are built, is expected to revolutionize the methods used to build space-based energy systems, and in the future will enable the efficient, large-scale construction of ultra-large space structures on the scale of hundreds of meters or even kilometers.
