# Fermi Explorer Mission Plans 2029 Launch Using AI-Designed Trajectory to Alpha Centauri

> A nonprofit is planning to launch a tiny spacecraft toward Alpha Centauri, and the most interesting part is how it will get there. An AI system was tasked with plotting the trajectory and came back with a route no one on the human team had considered, stringing together solar passes in a way that squeezes extra momentum out of the Sun's gravity. The mission, called Fermi Explorer, aims for a launch at the end of 2029 with a payload of a kilogram or more and a budget around 15 million dollars. The tooling came from a group called Physical Superintelligence, whose open-source system leaned on general models like Claude and GPT to search the enormous space of possible orbital maneuvers. The timescale is humbling: even with a clever slingshot, the projected journey to our nearest stellar neighbor runs on the order of 80,000 years. Still, it is a striking example of AI not just optimizing a known plan but discovering an approach humans missed.
