TLDR
- Space startup Starcloud, with backing from Nvidia, intends to deploy Bitcoin mining ASICs on its second satellite mission in 2026
- Company CEO Philip Johnston highlights that Bitcoin ASICs are dramatically more cost-effective at $1,000 per kilowatt compared to $30,000 for GPU technology
- The company has submitted FCC documentation to operate a massive constellation of 88,000 satellites hosting orbital computing facilities running on solar power
- Johnston predicts that space will become the inevitable home for Bitcoin mining operations due to Earth’s energy constraints
- Mining difficulty for Bitcoin has decreased 7% from its peak in November, providing temporary relief to mining operations
A U.S.-based space technology company called Starcloud has announced plans to deploy Bitcoin mining equipment in Earth’s orbit before the end of this year, potentially marking a historic first for cryptocurrency operations in space.
Company CEO Philip Johnston revealed the ambitious plan during a Thursday video conversation with HyperChange, later reiterating the commitment through posts on X during the weekend.
According to Johnston, the firm intends to incorporate Bitcoin mining ASICs โ specialized application-specific integrated circuits designed exclusively for cryptocurrency mining โ into its upcoming second spacecraft. The launch window is set for the latter part of 2026.
Established in the first quarter of 2024, Starcloud’s primary mission centers on constructing orbital data processing facilities to address the escalating power requirements driven by artificial intelligence applications.
The company achieved a milestone in November 2025 by successfully deploying a satellite equipped with an Nvidia H100 GPU into space. This marked the inaugural instance of such advanced GPU hardware functioning in an orbital environment. Johnston subsequently disclosed that one of the five GPUs aboard that satellite had exhibited connectivity issues prior to liftoff.
Starcloud has also submitted regulatory paperwork to the FCC seeking authorization to deploy and manage a constellation comprising 88,000 satellites. These orbital data centers would operate predominantly using solar energy collection systems.
Why ASICs Make More Sense in Space Than GPUs
Johnston contends that Bitcoin mining equipment presents a more practical solution for space-based operations compared to AI-focused GPUs, primarily due to economic factors.
“A 1-kilowatt B200 chip, it might cost $30,000. A 1-kilowatt ASIC is like $1,000,” he explained. This translates to ASICs being approximately 30 times more economical per kilowatt than GPU alternatives.
He maintained that Bitcoin’s present energy consumption โ approximately 20 gigawatts running continuously โ renders it unsustainable to maintain all mining infrastructure on Earth over the long term.
Nevertheless, Johnston conceded that the financial viability of space-based Bitcoin mining remains unproven. Mining returns can decline rapidly as newer, more powerful equipment enters the market.
Starcloud isn’t pioneering this concept alone. Intercosmic Energy, another company, has similarly been developing space-based Bitcoin mining capabilities.
Bitcoin Mining Context
Bitcoin’s valuation has plummeted nearly 48% from its October 6, 2025 peak of $126,080, creating pressure on mining operation profitability.
Yet mining difficulty has declined 7% from its November record of 155.9 trillion units to approximately 145 trillion currently, offering miners modest relief.
In related developments, brothers Jose and Carlos Puente have put forward a framework for transmitting Bitcoin transactions to Mars utilizing optical communication links combined with a novel interplanetary timestamp protocol. The duo maintains that actual Bitcoin mining operations on Mars would prove impractical given the significant signal delay between Earth and the red planet.
Starcloud’s second spacecraft mission, scheduled to carry the Bitcoin mining ASICs into orbit, remains on track for a launch later in 2026.
