Starcloud launched a spacecraft last year that carried an Nvidia H100 GPU into low Earth orbit, and company executives now say a follow-up mission will place ASIC Bitcoin miners on a second craft later this year. That move turns an orbital demo into an explicit test of whether crypto work can run in space at scale.
Bitcoin In Space: Operational Versus Launch Costs
Reports say the company argues running miners above the atmosphere could cut energy and cooling expenses. Solar panels provide steady power on certain orbits, and vacuum lets a satellite radiate heat away without gigantic air-conditioning systems.
Those are the savings Starcloud highlights. But getting machines into orbit and keeping them there carries its own price. Launch fees, protective shielding, and large radiators add mass and cost. Hardware replacements will be harder than swapping racks in Texas.
The company began life pitching orbital data centers for AI workloads, not just cryptocurrency. Reports indicate Starcloud’s longer-term plan is a constellation of compute platforms that can host commercial clients.
The cat is out of the bag: @Starcloud_-2 will be the first to mine in space.
This will be a massive industry in itself. Right now, bitcoin mining consumes about 20 GW of power continuously. It makes no sense to do this on Earth, and in the end state, all of this… pic.twitter.com/tmfr8rxGOL

Starcloud’s CEO, Philip Johnston, announced on X Saturday that the company aims to become the first to mine Bitcoin in space, following a discussion (video below) of its space mining plans on HyperChange Thursday.
For now, the test is narrow: install miners in orbit, see whether they run, measure uptime and energy math. Officials said the test is intended to provide hard numbers rather than slogans.
Hardware In Space Is Different Work
NVIDIA-backed publicity and a high-profile GPU flight drew attention, but civilian engineers and space systems experts point to several technical limits. Electronics face constant radiation. Memory and silicon degrade faster without heavy shielding.
Heat must be rejected through radiators, which increases surface area and mass. Reports note that ASICs optimized for Earth cooling cannot simply be transplanted into space and expected to last years.

Data shows terrestrial mining benefits from cheap local electricity, proximity to maintenance teams, and economies of scale that are already well understood. Putting those same miners in orbit removes easy access for repairs.
If a board fails, a replacement might require another rocket launch. That risk factors into any calculation of lifetime costs and return on investment.
