1An 80,000-Year Journey

Developed by Starcloud founders, Fermi Explorer will be humanity's first interstellar spacecraft. The 10cm cube satellite, planned for launch in 2029, will travel approximately 80,000 years to reach Alpha Centauri. The project aims to prove that interstellar travel is possible with current technology. Mission completion is calculated to take 79,800 years.

2Simple Yet Revolutionary Design

The 1kg cube satellite will use the Oberth maneuver to escape the solar system. It will orbit the sun elliptically for 12 years, gaining speed with each approach to achieve escape velocity. Expected to leave the solar system by early 2040s, this passive design keeps costs at $15 million. The mission demonstrates minimalist interstellar travel feasibility.

3Testing the Fermi Paradox

The project will test the 'Great Filter' theory behind the Fermi Paradox. The team aims to show two potential filters (impossibility and unwillingness of interstellar travel) can be overcome. If successful, it could answer why we haven't encountered other civilizations. This non-profit mission represents pure scientific curiosity.

4Technological Challenges

Designing a system to survive 80,000 years in space presents significant engineering hurdles. The cube must withstand micrometeorite impacts, cosmic radiation, and extreme temperature fluctuations. The team is developing simple yet effective solutions using existing materials. The design contains no active components, maximizing longevity.

5Previous Attempts

Breakthrough Starshot aimed to reduce interstellar travel to decades using laser propulsion but failed in 2025. Voyager 1 and 2 entered interstellar space in 2012 and 2018 respectively. Fermi Explorer will be the first human-made object intentionally sent to another star system. Unlike previous missions, it has a defined interstellar target.

6Starcloud's Other Ventures

The company primarily focuses on building space-based AI data centers. They launched an Nvidia H100 GPU via Starcloud-1 in 2025 and plan to deploy the full-scale Starcloud-2 commercial data center in 2027. Fermi Explorer represents a separate non-profit scientific initiative. The company maintains a dual strategy in space technology development.

7Cost and Logistics

Total project cost is estimated at $15 million, utilizing existing commercial rockets (like SpaceX) for launch. The cube satellite's simple design reduces development expenses. The main logistical challenge involves establishing tracking infrastructure for 80,000 years. The team plans to monitor the probe's position using Earth-based telescope networks.

8Symbolic Significance

Fermi Explorer could become the first scientific endeavor undertaken for generations who will never see its results. The project tests humanity's capacity for long-term thinking and collective goal-setting. If successful, it will materialize interstellar travel concepts for future generations. This mission has become an emblem of human curiosity and exploration.
