FERMI EXPLORER: THE 80,000-YEAR MISSION TO ALPHA CENTAURI
Non-profit Starcloud aims to launch an interstellar probe by 2029 for just $15M, utilizing AI-optimized trajectories and an 80,000-year flight plan.
Terminal Access: Interstellar Vectors
Starcloud has announced the Fermi Explorer mission, an ambitious non-profit initiative targeting humanity’s first physical reach toward Alpha Centauri. According to Payload, the project aims to succeed where previous high-budget endeavors stalled, proposing a launch by 2029 on a lean $15 million budget.
The AI Trajectory
CEO Philip Johnston leads the mission, which relies on a specialized "perihelion-pump" maneuver. The flight path was designed by Physical Superintelligence (PSI), an AI lab that processed 10 billion tokens to validate the trajectory. Following launch, the spacecraft will spend 12 years spiraling away from the Sun, utilizing solar passes to accelerate to a final exit velocity of ~24 km/s.
Generational Timelines
The mission is defined by deep-time parameters. While the spacecraft is expected to reach interstellar space faster than the Voyager probes, the journey to Alpha Centauri—four light-years distant—will take approximately 80,000 years.
Mission Objectives:
Budget: Sub-$15M for design, launch, and operation.
Payload: A 1kg CubeSat-class unit containing scientific data and artistic archives.
* Autonomy: High-level autonomous systems; radio communications will likely cease after the first year to save mass, with tracking handled via retroreflectors.
Funding and Legacy
Funding is being secured through donations rather than traditional venture capital. For a $100 contribution, donors can etch their names onto the hull. The craft will also carry a replica of the Voyager Golden Record. Per Payload, Johnston is already looking beyond this horizon, suggesting a follow-up $100M mission to the Andromeda galaxy with a billion-year arrival window.
