AI found a route to Alpha Centauri. Engineering still has to fly it.
An AI system helped find a surprising Alpha Centauri trajectory, but the article keeps the awe grounded. The proposed craft is cheap by space standards, solar powered, and very slow. The model found a plan; humans still have to test judgment, cost, mission design, and hardware.
What the source reports
MIT Technology Review says the nonprofit Fermi Explorer Mission plans to launch a spacecraft toward Alpha Centauri by the end of 2029. The route was found by an AI system from Physical Superintelligence. Alpha Centauri is 4.4 light-years away, and the trip could take up to 80,000 years. PSI is launching with $58 million in funding led by Breakthrough Energy. The Fermi mission is expected to cost about $15 million and carry at least one kilogram of cargo. The AI system, Get Physics Done, reportedly split the physics problem into tasks. It found a route using close solar passes and timed engine burns. The article notes limits: the paper was not peer-reviewed, an astrophysicist checked the output, and PSI’s CEO says models still lack reliable research judgment and taste.
