DARPA skips the lab, will head to orbit to test space manufacturing tech

DARPA's NOM4D program is progressing to space-based tests for orbital manufacturing technology. In 2026, Caltech and University of Illinois teams will conduct experiments in orbit. Caltech's robot will build a circular truss, while Illinois' team will test polymerizing carbon fiber tubes. These experiments aim to develop methods for constructing large structures in space, such as RF antennas, refueling stations, and solar array farms. Success could significantly impact future space exploration and the space economy.
