A robot just built a structure autonomously in space for the 1st time ever
AI-summarised brief · reviewed before publication
A DARPA‑funded robot built the first autonomous satellite structure in orbit, assembling a 1.4‑meter‑wide reflective antenna from Kapton film, composite tubes and aluminum joints. The “truss builder” operated on the ASTRA (Autonomous In‑Space Tensioned Reflector Assembly) demonstration, launched aboard Momentus’ Vigoride 7 on SpaceX’s Transporter‑16 rideshare on March 30. Engineers communicated with the robot for only 15 minutes per day, issuing commands that guided the manipulator to pick up parts and connect them on an assembly plate. Although time constraints prevented completion of the full truss, the mission proved the third phase of DARPA’s NOM4D program, which aims to enable scalable construction of structures hundreds of meters to kilometers long for megaconstellations, solar power arrays and large telescopes.
💡 Why It Matters
- · Autonomous in‑space assembly removes launch‑fairing size limits, unlocking the ability to deploy massive, on‑orbit infrastructures that were previously impossible.
