Robot builds structure in space for the first time
New York Post • • science
Key Points:
- A robot has successfully constructed a 1.4-meter-diameter reflector antenna in space autonomously, marking the first time a structure has been built in orbit without astronaut assistance.
- The robotic truss builder, developed by Caltech and funded by DARPA, is part of the NOM4D program and assembles structures by picking up and connecting struts and joints from nearby dispensers.
- This demonstration, named ASTRA, took six months in space to build the antenna using composite fiber tubes, aluminum joints, and a Kapton reflective surface, following successful design and testing phases on Earth.
- The technology could enable the construction of large-scale space structures such as massive reflector surfaces for telescopes, radio antennas, and solar power arrays that can harvest and transmit energy wirelessly to Earth.
- The project opens new research avenues for space manufacturing, with potential applications in astronomy, communications, and space-based solar power systems.
