GoKawiilStarcloud plans to launch Bitcoin mining ASICs aboard Starcloud-2 in 2027
Nvidia-backed startup Starcloud says it will fly dedicated Bitcoin mining hardware on its second satellite, Starcloud-2, targeting an early 2027 launch. CEO Philip Johnston argues that ASIC chips are far cheaper per kilowatt than GPUs, and that abundant orbital solar power could make space mining economically appealing, following the company's earlier Starcloud-1 test that put an Nvidia H100 GPU into orbit.
GoKawiil's interpretation of the reporting above, not reported fact.
Bitcoin mining's biggest cost is electricity, and if solar power in orbit proves cheaper and more reliable than terrestrial grids, it could reshape where and how mining operations are built. But the plan hinges on solving a hard physics problem: radiating heat away in a vacuum without convection, using only radiators, which could limit how much hardware can actually be packed and cooled in space.
- Starcloud aims to be first to mine Bitcoin in orbit via its Starcloud-2 satellite, expected to launch in 2027.
- ASIC miners are roughly 30 times cheaper per kilowatt than GPUs, but wear out technologically faster.
- Cooling in a vacuum via radiators, not air convection, remains the key unsolved engineering hurdle.
