If Space-Based Data Centers Are Not Viable, Should We Explore the Possibility of Interstellar Travel?

The Starcloud team, an innovative startup focused on establishing a network of GPUs in space, has proposed an intriguing opportunity for investors: the launch of a small spacecraft embarking on an extraordinary 80,000-year expedition to Alpha Centauri.

If successful, this mission would represent the first human-made object specifically designed to travel to another star, becoming the sixth entity to break free from our solar system’s confines.

This initiative, known as Fermi Explorer, is managed by a non-profit organization actively seeking collaborators, funding, and expert advice. The founding team includes Starcloud co-founders Philip Johnston, Adi Oltean, and Ezra Feilden, along with project manager Garret Jameson, who have created a plan to employ existing space technologies to propel a 1-kilogram spacecraft with a payload area of 10 cm² into interstellar space.

The founders emphasize that this mission is fueled by humanity’s inherent curiosity to explore, aiming for a remarkable milestone while tackling the Fermi paradox—the inquiry into why we have yet to encounter intelligent extraterrestrial life, which inspired the mission’s name.

The estimated budget for this pioneering mission is around $15 million, with a target launch date in 2029. The non-profit is on the lookout for contractors to design and manufacture the spacecraft, as well as financial partnerships and a variety of scientific and artistic payloads—similar to the components within NASA’s Voyager spacecraft, the first human-made object to exit our solar system.

Numerous prior attempts at interstellar exploration have floundered due to the immense distances and the relative sluggishness of our travel technologies. To illustrate, Voyager, which launched in 1977, is currently about 26 billion kilometers away from Earth, while Alpha Centauri, our closest stellar neighbor, is an astounding 41 trillion kilometers distant.

A previous effort in Silicon Valley aimed to confront these challenges by founding a non-profit called Breakthrough Starshot in 2016, backed by Yuri Milner and Mark Zuckerberg. This initiative sought to develop a multi-billion-dollar program using a groundbreaking laser propulsion system to reach Alpha Centauri within two to three decades. Unfortunately, it ultimately lost momentum before 2025, despite enduring interest in space exploration.

In contrast, Fermi Explorer takes a different route: instead of pushing technological boundaries, it aims to utilize existing resources to achieve something.

“I was once filled with hope but then faced disappointment!” Johnston reflected on the Starshot initiative. “That’s why we are committed to this mission. We intend to launch something within three years. … The crucial difference between most other [interstellar] projects and Fermi Explorer is that they strive to accomplish their goals within a human lifetime, necessitating billion-dollar propulsion R&D investments. We have intentionally established an 80,000-year timeline as our minimum viable mission.”

The plan involves launching the spacecraft via a rocket rideshare, followed by efficient, low-power electric propulsion to navigate through various orbits, ultimately guiding it toward Alpha Centauri. The spacecraft is expected to function for around 12 years before embarking on a prolonged coast phase toward the neighboring star system.

“If a dinosaur bone can survive for 200 million years, then a metal container should easily endure the radiation expected for 50,000 years,” asserted Johnston. “We do not intend to reactivate the spacecraft after 80,000 years. Our hope is that a future human civilization will find it.”
