If space data centers feel far-fetched, why not interstellar travel?

Starcloud, a startup with ambitions to launch GPUs into space, has introduced an audacious new proposal: sending a spacecraft on an 80,000-year journey to Alpha Centauri. Dubbed Fermi Explorer, this non-profit team, comprising founders Philip Johnston, Adi Oltean, and Ezra Feilden, along with program manager Garret Jameson, is seeking partners and donations to bring their mission to life.

The goal is to create history by launching the first human-made object explicitly designed for another star, and the sixth object to leave our solar system.

The team aims to use established space technologies to send a lightweight vehicle, weighing just 1 kilogram, into interstellar space. The mission, projected to cost around $15 million and launch in 2029, is intended to test the boundaries of human exploration and tackle the Fermi paradox, a theory that attempts to explain why we have not yet encountered other intelligent life in the universe.

The journey is a formidable challenge, given the immense distances involved—Alpha Centauri, the nearest star, lies 41 trillion km away from Earth. Current propulsion methods are ill-suited for such long voyages, as evidenced by the long-standing failure of Breakthrough Starshot in 2025. Instead, Fermi Explorer takes a different approach, choosing to leverage existing technologies instead of pushing for advanced propulsion systems.

The spacecraft, once launched, will rely on electric propulsion and efficient maneuvers to eventually become an independent interstellar traveler. It is designed to function for approximately 12 years before entering a coast phase towards Alpha Centauri. Johnston, one of the founders, compares the spacecraft's durability to that of a dinosaur bone, asserting that a metal box should withstand the radiation environment for 50,000 years without needing power at the end of the mission. The ultimate hope is that a future advanced civilization might intercept the payload.
