DARPA’s NOM4D Phase 3 includes a 2026 Caltech experiment in which a gantry robot will autonomously assemble a 1.4-metre circular composite truss in low Earth orbit. The demonstration targets mass-efficient construction of large apertures and validates robotic assembly methods applicable to orbital solar power, communications, and deep-space infrastructure.
