An orbital computing startup is moving one of crypto’s most energy-intensive businesses off Earth. Starcloud, a US space infrastructure company formerly known as Lumen Orbit, says it plans to begin Bitcoin mining in orbit later in 2026 by flying mining-specific hardware on its second satellite. The announcement places the company at the center of two fast-moving trends: the race to build space-based data centers and the search for cheaper, cleaner power for high-performance computing.
A new chapter for orbital computing
The phrase “Orbital data center company to start mining Bitcoin in space” has shifted from science-fiction headline to a concrete commercial plan. Starcloud announced on March 7, 2026, that it intends to fly Bitcoin mining ASICs on its upcoming Starcloud-2 mission, aiming to become the first company to mine Bitcoin in space. Coverage published on March 9 said the company expects to begin orbital mining later this year.
Starcloud is part of a broader push to place computing infrastructure in low Earth orbit. The company’s first satellite, Starcloud-1, was described as a demonstrator for “data-center-class” computing in space, with the goal of validating high-end GPU operations in the orbital environment. Company materials and industry coverage say the spacecraft is designed to test whether space can support workloads that normally require large terrestrial data centers, including AI processing and other compute-heavy applications.
That matters because Bitcoin mining is, at its core, a specialized computing task. Instead of general-purpose GPUs, miners typically use ASICs, chips built specifically to perform the SHA-256 calculations that secure the Bitcoin network. By moving those machines into orbit, Starcloud is betting that abundant solar energy and the cold vacuum of space can improve the economics of mining while reducing some of the land, grid, and cooling constraints that affect Earth-based facilities.
Why an orbital data center company wants to mine Bitcoin in space
The commercial logic behind the plan is straightforward, even if the engineering is not. Bitcoin mining profitability depends heavily on three variables:
- Access to low-cost energy
- Efficient cooling and thermal management
- Reliable hardware uptime
On Earth, those factors are increasingly difficult to optimize at scale. Large mining sites consume enormous amounts of electricity and generate substantial waste heat. A recent report on satellite thermal imaging highlighted the environmental scrutiny facing major US mining operations, noting that one large Rockdale, Texas, facility consumes about 700 megawatts, roughly as much electricity as 300,000 homes.
Space offers a different model. Solar power is continuous for long stretches in certain orbital profiles, and radiative cooling in vacuum can, in theory, reduce some of the overhead associated with traditional air- or liquid-cooled data centers. SpaceB, another company promoting orbital mining, describes the concept as using near-continuous solar flux and vacuum radiative cooling to improve efficiency and resilience. While those claims remain largely unproven at scale, they reflect the same thesis now being tested by Starcloud.
According to Philip Johnston, cited in recent coverage, Starcloud sees Bitcoin mining in orbit as a future business that can capitalize on cheap solar energy in space. That statement is important because it frames mining not as a publicity stunt, but as a possible revenue line within a larger orbital compute strategy.
The company behind the plan
Starcloud was founded in 2024 under the name Lumen Orbit and later rebranded. Publicly available profiles identify its founders as Philip Johnston, Adi Oltean, and Ezra Feilden. Recent reporting says the company is backed by Nvidia and has positioned itself as a builder of orbital data centers rather than a pure crypto venture.
A March 8 local news report said Starcloud launched its first satellite, Starcloud-1, into low Earth orbit and claimed its space-based data center architecture could eventually deliver significantly higher efficiency than terrestrial alternatives. The same report said the startup had raised a $2.4 million pre-seed round and was valued at about $100 million in early 2026. Those figures should be viewed as startup-stage indicators rather than proof of commercial maturity, but they show investor interest in the concept.
The company’s longer-term ambition appears much larger than a single crypto payload. Industry pages describing Starcloud’s platform say the first demonstrator weighs about 60 kilograms and is intended to validate high-performance computing in radiation-heavy conditions. If those tests succeed, Bitcoin mining could become one of several monetization paths for orbital compute capacity, alongside AI inference, edge processing, and secure off-world data storage.
Technical hurdles remain significant
For all the excitement around the headline “Orbital data center company to start mining Bitcoin in space,” the technical barriers are substantial. Space hardware must survive launch stress, radiation exposure, thermal cycling, and limited opportunities for repair. Bitcoin mining ASICs are designed for efficiency, but they are still power-dense chips that generate heat and require stable operating conditions.
There is also the question of economics. Launch costs have fallen, but sending hardware into orbit is still expensive compared with deploying miners in Texas, Wyoming, or overseas energy hubs. Any orbital mining model must show that the value of free solar input, reduced terrestrial cooling needs, or premium compute flexibility outweighs the cost of launch, spacecraft integration, communications, and mission risk. That calculation has not yet been proven publicly.
Network connectivity is another issue. Bitcoin mining does not require high-bandwidth links, but it does require reliable communication with the network to receive block templates and submit valid shares or blocks. Academic work on interplanetary Bitcoin and delay-tolerant networking suggests that blockchain operations across high-latency links are technically possible, though practical implementation depends on architecture and mission design.
Competition is already forming
Starcloud is not alone in seeing space as the next frontier for compute. Lonestar is developing data center infrastructure beyond Earth, with TechCrunch reporting in February 2025 that its systems were headed to the moon in partnership with Phison. The company focuses on resilient storage and disaster recovery rather than crypto mining, but its progress shows that off-world data infrastructure is becoming a real commercial category.
At the same time, larger geopolitical and corporate players are entering the field. Space.com reported in early 2026 that China had added space-based data centers to a new five-year plan. Tom’s Hardware also reported that SpaceX had formalized plans in an FCC filing for a vast orbital data center system. Those efforts differ in scope and purpose, but they reinforce the idea that orbital compute is moving from concept to competition.
What it means for Bitcoin, energy, and investors
The significance of this development goes beyond crypto. Bitcoin mining has become a test case for how the world allocates energy to digital infrastructure. In recent years, several major mining companies have pivoted toward AI and data center services, reflecting pressure on mining margins and growing demand for GPU capacity. Tom’s Hardware reported in late 2025 that Bitfarms planned to fully abandon crypto mining by 2027 in favor of AI-focused infrastructure.
That makes Starcloud’s move notable. While some miners are leaving Bitcoin for AI, an orbital data center company is exploring the reverse path: using a data center platform to add Bitcoin mining as a specialized workload. If successful, the model could reshape how investors think about stranded energy, off-grid compute, and the future location of digital infrastructure.
For US stakeholders, the implications are mixed:
- Crypto investors may see orbital mining as a sign of continued innovation in Bitcoin infrastructure.
- Energy policymakers may view it as a possible way to reduce pressure on local grids, though only if launches and satellite operations scale responsibly.
- Space regulators will likely focus on orbital congestion, debris mitigation, and spectrum use.
- Data center operators may watch closely for lessons on cooling, power architecture, and modular compute design.
Outlook for the orbital Bitcoin mining experiment
The next milestone is execution. Starcloud still has to launch Starcloud-2, operate mining hardware in orbit, and show that the system can function reliably enough to produce economically meaningful results. Until that happens, the project remains an ambitious test rather than a proven business model.
Still, the announcement marks a turning point. Space-based data centers were once discussed mainly in the context of defense, disaster recovery, and AI. By adding Bitcoin mining to the list, Starcloud is broadening the commercial case for orbital infrastructure and forcing a new conversation about where the next generation of compute should live.
Conclusion
The story behind “Orbital data center company to start mining Bitcoin in space” is bigger than a single crypto experiment. It reflects a convergence of falling launch costs, rising demand for compute, pressure on terrestrial power systems, and a growing willingness among startups to commercialize space infrastructure. Starcloud’s plan may still face steep technical and financial hurdles, but it has already achieved one thing: it has turned orbital computing from a niche engineering idea into a mainstream business debate.
