Columbia University’s latest engineering project is straight out of a sci-fi novel, but it’s based on a simple idea: what if robots could grow, heal and adapt by absorbing parts from other robots? They call it “robot metabolism” and it flips traditional robotics on its head, from stiff, electricity-driven machines to robots that act like living organisms, using materials from their environment to evolve.

The X-59 rolled out of the Lockheed Martin Skunk Works hangar in Palmdale, California on July 10, 2025 and is now taxiing on its own power for the first time. This is the final step before flight for the NASA Quesst mission aircraft. Central to the Quesst mission is the X-59 which will change the way we think about supersonic travel and potentially open the skies to commercial aviation.
