If Space-Based Data Centers Fail, Could Interstellar Travel Be Our Next Frontier?

The Starcloud team, a pioneering startup focused on establishing a network of GPUs in space, has unveiled an exciting investment opportunity: the launch of a small spacecraft embarking on a remarkable 80,000-year mission to Alpha Centauri.

Should this mission succeed, it will signify the first human-made object intentionally crafted for interstellar travel, joining an elite group as the sixth entity to exit our solar system.

Dubbed Fermi Explorer, this initiative is led by a non-profit organization that is actively seeking collaborators, funding, and specialized knowledge. The founding team comprises Starcloud co-founders Philip Johnston, Adi Oltean, and Ezra Feilden, along with project manager Garret Jameson, who have developed a plan to utilize current space technologies to launch a 1-kilogram spacecraft with a payload area of 10 cm² into interstellar space.

The founders emphasize that this mission springs from humanity’s intrinsic desire to explore, striving for a monumental achievement while tackling the Fermi paradox—the query regarding our inability to find intelligent extraterrestrial life, which inspired the project’s name.

The estimated budget for this groundbreaking mission is around $15 million, with a launch target set for 2029. The non-profit is on the lookout for contractors to design and build the spacecraft, seek financial partners, and gather a variety of scientific and artistic payloads, similar to those onboard NASA’s Voyager spacecraft, the first human-made object to depart our solar system.

Numerous previous efforts at interstellar travel have faced hurdles due to immense distances and the limited pace of our current travel technologies. For perspective, Voyager, launched in 1977, is currently approximately 26 billion kilometers from Earth, while Alpha Centauri, our closest stellar neighbor, lies an astounding 41 trillion kilometers away.

A prior initiative in Silicon Valley aimed to address these challenges through the establishment of a non-profit called Breakthrough Starshot in 2016, backed by Yuri Milner and Mark Zuckerberg. This program sought to spearhead a multi-billion-dollar endeavor utilizing an advanced laser propulsion system to reach Alpha Centauri within two to three decades. Regrettably, it lost momentum before 2025, despite continued interest in space exploration.

In contrast, Fermi Explorer proposes a different approach: rather than pushing technological boundaries, it seeks to optimize existing resources to achieve something.

“I was filled with hope but then faced disappointment!” Johnston reflected on the Starshot initiative. “That’s why we are committed to this project. Our goal is to launch something within three years. … The significant difference between most other [interstellar] projects and Fermi Explorer is that they aim to achieve their objectives within a human lifetime, which requires multi-billion-dollar propulsion R&D investments. We have consciously set an 80,000-year timeline as our minimum viable mission.”

The project entails launching the spacecraft via a rocket rideshare, followed by efficient, low-power electric propulsion to navigate through various orbits, ultimately steering it toward Alpha Centauri. The spacecraft is expected to function for approximately 12 years before entering a lengthy coast phase towards the neighboring star system.

“If a dinosaur bone can endure for 200 million years, then a metal container should easily withstand the radiation anticipated for 50,000 years,” noted Johnston. “We do not plan to reactivate the spacecraft after 80,000 years. Our aspiration is that a future civilization will find it.”
