Nonprofit Plans 80,000-Year Mission to Alpha Centauri - for Under $15 Million

A newly formed nonprofit called the Fermi Explorer Mission says it plans to launch humanity's first spacecraft deliberately aimed at another star system - and it wants to do it by the end of 2029, for less than $15 million.

The target is Alpha Centauri, the sun's nearest stellar neighbor at roughly 4.4 light-years away. Because no propulsion technology exists that could get a spacecraft there quickly, the mission accepts an almost unimaginable timeline: the probe won't actually arrive for about 80,000 years, long after everyone involved in building it - and everyone alive today - is gone.

The project comes from Starcloud co-founders Philip Johnston, Adi Oltean, and Ezra Feilden, who set up the Redmond, Washington-based nonprofit specifically for this mission. Their self-imposed rules are strict: the spacecraft must be aimed at Alpha Centauri, carry at least one kilogram of payload, launch before the end of 2029, and cost under $15 million to design, build, launch, and operate - a fraction of what a typical interplanetary mission costs.

To hit that budget, the mission leans on an unusual trajectory. After deploying from its launch vehicle, the spacecraft would loop repeatedly around Earth and the sun, using a series of gravity-assisted "perihelion pumping" maneuvers to build up speed before finally breaking free toward interstellar space. The path was discovered not by a traditional orbital mechanics team, but by an AI system built by Physical Superintelligence (PSI), an AI physics research lab that emerged from stealth with $58 million in seed funding.

Whether the mission ever reaches its target obviously can't be verified by anyone now alive, and skeptics will note that an 80,000-year journey guarantees nothing about the spacecraft surviving interstellar dust, radiation, or simple hardware failure over such an extreme span. But the team's stated goal isn't really about the eventual arrival - it's about proving, cheaply and soon, that a small, low-cost spacecraft can be deliberately launched toward another star at all, something no mission has ever formally attempted.
