Starcloud-2 plans to carry Bitcoin mining ASICs into orbit, targeting cheap solar energy to make space-based BTC mining a viable future industry.
Starcloud, a US orbital data center startup, has confirmed plans to include Bitcoin mining hardware on its second satellite launch. The move marks what could be a first in crypto history. Bitcoin mined in orbit, powered entirely by the Sun.
Speaking on the HyperChange YouTube channel, Starcloud CEO Philip Johnston confirmed that the upcoming Starcloud-2 spacecraft will carry Bitcoin mining ASICs. As Philip Johnston posted on X, the Starcloud-2 will be the first satellite to mine Bitcoin in space, calling it what he expects to become “a massive industry in itself.”
The Bitcoin network currently draws roughly 20 GW of continuous power. That figure alone makes Johnston’s case. He told HyperChange that running all that compute on Earth no longer makes sense when solar energy in orbit is effectively unlimited.
The Solar Angle Nobody Saw Coming
Johnston told PCMag that Starcloud views space-based Bitcoin mining as a future business built around cheap energy from the Sun. That is the same logic driving data center interest from companies including SpaceX. The difference here is the hardware cost gap.
Bitcoin ASICs range from $600 to a few thousand dollars. Nvidia enterprise GPUs run $30,000 and up. Johnston told PCMag the launch cost break-even for GPU infrastructure sits around $500 per kilogram. Bitcoin mining hardware could potentially work closer to $200 per kilogram. That gap matters enormously when payload weight is money.
Still, Johnston did not oversell it. The economics of space-based Bitcoin mining are shaky, he acknowledged. ASIC profitability can evaporate fast as newer models hit the market. Hash price has already fallen to levels that make mining unprofitable for many operators on Earth.
88,000 Satellites and One Mining Rig
Starcloud filed a request with the FCC to operate 88,000 satellites for orbital data centers. The Starcloud-2 satellite will carry a GPU cluster designed to generate 100 times more solar power than the first satellite. Bitcoin ASICs ride along as part of that broader compute stack.
The company launched its first satellite in November, carrying an Nvidia H100 GPU into orbit. That made Starcloud the first to run a GPU that powerful in space. One of five GPUs failed before launch, Johnston told PCMag. It was “unresponsive before we launched it,” he said. The company pressed on anyway.
Johnston told PCMag, “We think we’ll be the first to mine a coin in space.” Another firm, Intercosmic Energy, has also been exploring space-based Bitcoin mining, so the race has more than one runner.
A New Frontier for Bitcoin Decentralization
Bitcoin mining in orbit also carries a decentralization argument. Keeping mining hardware off the terrestrial grid, spread across orbit, reduces geographic concentration risk. Starcloud is not the first company to connect crypto to space infrastructure. Blockstream has long broadcast the Bitcoin blockchain via satellite.
But actually mining coins in orbit is a different proposition entirely. It requires sustained compute, thermal management in a vacuum, and reliable power delivery. Starcloud says solar handles the energy side. The rest is an engineering problem they are working through.
Johnston’s comment on X put it plainly. Earth-based Bitcoin mining, consuming 20 GW of power continuously, does not make sense long term. In the end state, he wrote, all of it will be done in space.
No specific date has been confirmed. Whether the economics ultimately work is still an open question, but the technology test alone could reshape how the industry thinks about energy-hungry proof-of-work computers.
