Bitcoin mining could soon cross an unprecedented frontier: space. The American startup Starcloud, backed by Nvidia, has announced its intention to deploy ASIC mining chips on its next satellite in low Earth orbit (LEO). If the project succeeds, it would be the first cryptocurrency mining operation carried out in space.
This announcement comes at a time when the Bitcoin mining industry faces growing challenges in terms of energy consumption and equipment cooling. The Bitcoin network consumes approximately 211 terawatt-hours (TWh) per year, equivalent to the electricity consumption of a country like Thailand. Could space offer a solution to these issues? That is the ambitious bet made by Starcloud and other emerging players.
Starcloud: From GPU in orbit to Bitcoin mining
A successful first satellite
Founded in early 2024, Starcloud set out to build orbital data centers capable of meeting the growing demand for computing power, particularly for artificial intelligence. In November 2025, the startup achieved a major milestone by launching its first satellite, Starcloud-1, equipped with an Nvidia H100 GPU. This graphics processor, 100 times more powerful than any GPU previously operated in space, enabled the first-ever large language model (LLM) to run in orbit — specifically Gemma, Google’s open-source model.
This technical demonstration proved that high-performance computing hardware could operate reliably in the space environment. Building on this success, Starcloud raised funds from Nvidia and now has far broader ambitions.
Space mining planned for 2026
Starcloud CEO Philip Johnston stated that the company’s second satellite, scheduled for launch in October 2026, will carry Bitcoin mining ASIC chips alongside several Nvidia H100 GPUs and the new Nvidia Blackwell platform. Johnston says he wants to be “the first to mine a coin in space.”
Why ASICs rather than GPUs for mining? As Johnston explains, ASICs are approximately 30 times cheaper than GPUs per kilowatt-hour consumed, making them a far more cost-effective choice for Bitcoin mining in an environment where every watt of energy must be optimized.
Why mine Bitcoin in space?
Nearly unlimited solar energy
One of the main advantages of mining in orbit lies in access to space-based solar energy. Unlike on Earth, where solar panels are limited by the day/night cycle, weather conditions, and the atmosphere, solar panels in orbit capture sunlight nearly 24 hours a day, 7 days a week, for 99% of the year. According to data from the US Naval Research Laboratory, space-based solar panels can collect up to 40 times more annual energy than their terrestrial counterparts.
For a mining industry where electricity represents the largest cost, this access to abundant and free solar energy is a compelling argument. As a reminder, in 2026, producing a single Bitcoin requires approximately 854,400 kWh of electricity, equivalent to over 81 years of average residential consumption.
Natural cooling from the vacuum of space
The second major advantage is cooling. On Earth, mining farms must invest heavily in air conditioning and ventilation systems to dissipate the heat generated by ASIC machines. These cooling systems account for a significant portion of operational costs and overall energy consumption.
In the vacuum of space, this problem largely disappears. The absence of atmosphere allows natural thermal dissipation, eliminating the need for costly and energy-intensive cooling systems. The challenge is actually reversed: in space, maintaining a minimum temperature becomes the primary concern, rather than dissipating heat.
Other strategic advantages
Beyond energy and cooling, space mining offers additional benefits. There is no competition for land use, a criticism often leveled at large terrestrial mining farms. The absence of weather conditions also simplifies operational maintenance. Finally, the orbital location provides a degree of jurisdictional neutrality, as satellites are not subject to the same regulations as terrestrial installations.
The challenges of mining in orbit
Launch costs
The main obstacle to space mining remains the cost of sending equipment into orbit. Currently estimated at approximately $5,000 per kilogram, this cost makes the operation economically complex. However, with the continued decline in launch costs, particularly thanks to SpaceX’s reusable rockets, projections suggest a reduction of up to 99% over the next decade. If these forecasts prove correct, the economics of space mining could become favorable.
Environmental constraints
The space environment imposes its own constraints. Cosmic radiation can damage electronic components and reduce the lifespan of ASIC chips. Extreme temperature variations between sun-exposed areas and shadowed areas also pose a technical challenge. Maintenance and replacement of failing equipment are obviously much more complex and costly than on Earth.
Connectivity and latency
Mining Bitcoin relies on the Proof-of-Work protocol, where the speed of block resolution is crucial. Communication latency between a satellite in low Earth orbit and the Bitcoin network’s terrestrial nodes could pose a problem. Every millisecond of delay can mean losing a block to a terrestrial miner. This factor will need to be carefully optimized to ensure the competitiveness of space mining.

Starcloud’s competitors
Starcloud is not the only company exploring Bitcoin mining in space. Intercosmic Energy, founded by Nick Moran, a former industrial cooling specialist, is also working on the subject. The startup highlights the same advantages as Starcloud: continuous sunlight and cooling through the vacuum of space.
Meanwhile, Lumen Orbit has raised $2.4 million to launch hundreds of satellites functioning as space-based data centers. Although this startup focuses more on general-purpose computing hosting, it is contributing to the emergence of a genuine orbital data center infrastructure.
It is also worth noting that the SpaceChain Foundation had installed blockchain hardware on the International Space Station (ISS) as early as 2020, integrating multi-signature wallet technology. This pioneering initiative added two additional factors to blockchain solutions: remoteness and the security of low Earth orbit.
Starcloud’s large-scale vision
Starcloud’s ambition extends well beyond simple Bitcoin mining. The company has filed an application with the Federal Communications Commission (FCC) to operate a constellation of 88,000 satellites dedicated to orbital data centers. Ultimately, Starcloud aims to build a 5-gigawatt orbital data center, with solar and cooling panels approximately 4 kilometers wide and long.
Starcloud’s second satellite will have 100 times the energy generation capacity of the first. It will also integrate a cloud platform from Crusoe, allowing clients to deploy and operate AI workloads directly from space.
What impact on the mining industry?
The Bitcoin mining industry is undergoing a period of transformation. The network’s hashrate reached a record 894.5 exahashes per second (EH/s) in mid-2025, nearly doubling compared to mid-2024. The share of renewable energy in the mining energy mix rose to 52.4% in 2025, up from 37.6% in 2022.
Geographically, the United States dominates global mining with 37.8% of the hashrate, followed by Russia (15.5%) and China (14.1%) despite the official ban in 2021. The emergence of space mining could reshuffle these rankings by introducing a player that is not attached to any national territory.
If space mining proves viable at scale, it could help resolve one of the most persistent debates surrounding Bitcoin: its environmental footprint. Mining powered exclusively by space-based solar energy, without artificial cooling, would represent a near carbon-neutral model. However, this prospect remains largely theoretical for now and will depend on the ability of industry players to overcome the numerous technical and economic challenges.
The launch of Starcloud’s second satellite, scheduled for October 2026, will serve as a full-scale test of this vision. If the startup successfully mines a Bitcoin block from space, it will have opened a new chapter in the history of cryptocurrency and space exploration.
