According to the latest market reports, Starcloud, a U.S.-based startup strategically invested in by NVIDIA and focused on space-based computing power, has officially announced through its CEO Philip Johnston that its Starcloud-2 satellite is scheduled for launch in 2026. The satellite will carry specialized Bitcoin ASIC mining machines into orbit, becoming the world’s first spacecraft to enable Bitcoin mining in space.
This initiative marks not only the first integration of space-based computing with cryptocurrency mining, but also a key milestone in Starcloud’s “compute-in-space” strategy. As a core investor, NVIDIA will continue to support the project by providing advanced chip technology for its computing hardware.
Philip Johnston stated that space mining represents a critical future direction for the cryptocurrency mining industry. This view is primarily driven by the severe energy consumption challenges currently facing Bitcoin mining on Earth. By the end of 2025, global Bitcoin mining power consumption had approached 20 gigawatts—equivalent to the total national energy usage of mid-sized European countries such as the Netherlands or Finland. On an annual basis, electricity consumption rivals that of countries like Poland or Argentina. This high energy demand has not only sparked global debates over energy allocation, but has also led to rising grid pressure and electricity price volatility in multiple regions, becoming a key bottleneck for industry growth. Starcloud’s move to shift mining operations into space aims to address this issue at its root.
Unlike terrestrial mining, which relies heavily on traditional power grids, the Starcloud-2 satellite will leverage the unique environment of low Earth orbit to achieve breakthroughs in both energy generation and thermal management. Positioned in a sun-synchronous orbit, the satellite can receive near-continuous solar radiation, eliminating limitations caused by day-night cycles and weather conditions. Its solar panels are expected to achieve significantly higher efficiency than those on Earth, with electricity costs as low as $0.002 per kilowatt-hour, dramatically reducing energy expenses.
At the same time, the vacuum of space serves as a natural “infinite heat sink.” Without the need for energy-intensive cooling systems such as liquid or air cooling used in terrestrial mining farms, the satellite can dissipate heat directly into space via radiators, effectively solving the thermal challenges of continuous ASIC operation. Additionally, Starcloud-2 will be equipped with enhanced NVIDIA GPU clusters working in synergy with ASIC miners, enabling both Bitcoin mining and on-orbit data processing, thereby maximizing the utilization of space-based computing resources.
In fact, Starcloud’s space computing strategy has been in development for some time, and this mining initiative is not a sudden experiment. In November 2025, the company launched its Starcloud-1 satellite aboard a Falcon 9 rocket developed by SpaceX. Roughly the size of a refrigerator, the satellite carried an NVIDIA H100 processor into space and successfully completed the training of a small AI model in orbit, validating the feasibility of deploying high-performance computing hardware in space. The upcoming Starcloud-2 represents a significant upgrade in hardware configuration, energy supply, and computing scale. Its computing power is estimated to be 100 times greater than the current server capacity aboard the International Space Station, and it will be capable of processing large volumes of raw data generated in orbit in real time.
From a long-term perspective, space mining is only an early test case within Starcloud’s broader space computing ecosystem. The company has already submitted an application to the U.S. Federal Communications Commission (FCC) to deploy a constellation of up to 88,000 satellites. Its ultimate goal is to build an orbital data center with a power capacity of 5 gigawatts, equipped with a 4-square-kilometer solar array. Through inter-satellite laser links, the system would connect with satellite internet constellations such as SpaceX’s Starlink and Amazon’s Kuiper, enabling low-latency global space-based computing services.
Bitcoin mining was chosen as the first application primarily because ASIC mining hardware is significantly less expensive than high-end AI chips, and mining fundamentally converts electrical energy into cryptographic computation. This makes it an efficient way to monetize surplus solar energy generated in orbit, while also providing valuable technical and commercial experience for future space-based AI computing centers.
However, this groundbreaking initiative still faces multiple challenges in terms of technology, cost, and regulation. Technically, cosmic radiation and microgravity environments impose stringent requirements on the reliability and stability of ASIC hardware, while in-orbit maintenance and fault management remain largely unresolved. From a cost perspective, the expense of launching satellites—currently reaching tens of millions of dollars per mission—remains a major barrier, and further cost reductions through modular deployment will take time.
Regulatory challenges are even more complex. Many countries impose strict controls on cryptocurrency mining, with China explicitly classifying related activities as illegal financial operations. Issues such as data transmission and revenue settlement from space-based mining will need to comply with varying national regulations. Furthermore, under the Outer Space Treaty, outer space is considered the common heritage of humanity, meaning Starcloud’s activities must also adhere to international space law. Satellite launches, spectrum allocation, and orbital operations all require approval from multiple regulatory authorities.
Despite these challenges, Starcloud’s efforts offer new perspectives for the global computing and cryptocurrency industries. As terrestrial computing faces increasing constraints in energy, land, and cooling, space-based computing is emerging as a trillion-dollar opportunity. With the involvement of major technology companies like NVIDIA, the pace of technological advancement in this field is accelerating.
If successfully validated both technically and commercially, this experiment in space mining could reshape the Bitcoin mining industry and lay the foundation for broader applications of space-based computing in AI training, remote sensing, and financial analytics—ushering humanity from the era of “ground-based computing” into the age of “computing in space.”
