Bitcoin mining is leaving the realm of mere science fiction. Starcloud, an American startup backed by Nvidia, says it will carry a mining ASIC on its second spacecraft later in 2026. If the lawsuit succeeds, the company would become the first to mine bitcoins from Earth orbit.
In short
- Starcloud wants to launch the first Bitcoin mining ASIC in orbit as early as 2026.
- The project makes space mining credible on a technical level.
- However, true profitability remains to be proven.
Starcloud wants to make Bitcoin a credible use case in space
Starcloud is no longer talking about a vague concept, but about a concrete test announced by its CEO Philip Johnston. His bet is based on a simple idea. In space, solar energy is abundant, continuous, and does not compete directly with terrestrial power grids. For Starcloud, this could turn Bitcoin mining into a natural use of orbital computing, much easier than heavy AI that requires much more expensive GPU chips.
The Starcloud project doesn’t come out of nowhere. Founded in 2024, the company initially works on orbital data centers designed to meet explosive computing needs, especially for AI. It has already launched a satellite equipped with an Nvidia H100 GPU into orbit and then claimed to run and even train artificial intelligence models in space.
In this context, Bitcoin seems almost like a logical detour. Philip Johnston explains that ASICs cost much less per watt than GPUs. It provides value on the order of about $1,000 for a 1 kilowatt ASIC versus up to $30,000 for a B200 chip of equivalent power. From this angle, mining becomes a more realistic gateway to orbital profitability for Starcloud.
This detail changes the reading of the file. Starcloud isn’t just trying to make a name for itself with a marketing ploy. It also attempts to demonstrate that space can host simple, energy-intensive and highly standardized computing activities. And Bitcoin mining fits that profile exactly. It does not require a complex interface. It mainly needs electricity, specialized machines, reliable connection.
An ambitious promise, but still far from a proven model
The discourse is appealing. Johnston goes even further, estimating that bitcoin mining consumes about 20 gigawatts of continuous power, and that in the long term, a significant portion could be moved into space. The idea captures the imagination. But the gap between a technical demonstration and a truly viable industry remains huge.
Because orbital calculations still have major flaws. Startup costs remain high. The hardware must survive radiation, debris, thermal constraints and almost non-existent maintenance. Several industry players are advocating for space-based data centers, but mainstream voices remain skeptical about their medium-term profitability. Reuters reported in early February that the head of AWS considered these infrastructures to be very far from a solid economic reality.
In other words, space mining of Bitcoin is becoming technically possible. This does not mean that it will immediately become competitive. Starcloud plays a pioneering role here. The market will wait for proof: real yield, device lifetime, hash cost, orbit reliability and return on investment. As long as these points remain vague, the project is still more advanced testing than industrial revolution.
