Starcloud launched a spacecraft final yr that carried an Nvidia H100 GPU into low Earth orbit, and firm executives now say a follow-up mission will place ASIC Bitcoin miners on a second craft later this yr. That transfer turns an orbital demo into an specific check of whether or not crypto work can run in area at scale.
Bitcoin In House: Operational Versus Launch Prices
Studies say the corporate argues working miners above the ambiance may minimize power and cooling bills. Photo voltaic panels present regular energy on sure orbits, and vacuum lets a satellite tv for pc radiate warmth away with out gigantic air-conditioning programs.
These are the financial savings Starcloud highlights. However getting machines into orbit and maintaining them there carries its personal worth. Launch charges, protecting shielding, and huge radiators add mass and value. {Hardware} replacements shall be more durable than swapping racks in Texas.
The corporate started life pitching orbital knowledge facilities for AI workloads, not simply cryptocurrency. Studies point out Starcloud’s longer-term plan is a constellation of compute platforms that may host industrial purchasers.
The cat is out of the bag: @Starcloud_-2 would be the first to mine 𝗕𝗶𝘁𝗰𝗼𝗶𝗻 in area.
This shall be an enormous trade in itself. Proper now, bitcoin mining consumes about 20 GW of energy constantly. It is senseless to do that on Earth, and ultimately state, all of this… pic.twitter.com/tmfr8rxGOL

Starcloud’s CEO, Philip Johnston, introduced on X Saturday that the corporate goals to grow to be the primary to mine Bitcoin in area, following a dialogue (video beneath) of its area mining plans on HyperChange Thursday.
For now, the check is slim: set up miners in orbit, see whether or not they run, measure uptime and power math. Officers mentioned the check is meant to offer laborious numbers somewhat than slogans.
{Hardware} In House Is Totally different Work
NVIDIA-backed publicity and a high-profile GPU flight drew consideration, however civilian engineers and area programs specialists level to a number of technical limits. Electronics face fixed radiation. Reminiscence and silicon degrade sooner with out heavy shielding.
Warmth have to be rejected by way of radiators, which will increase floor space and mass. Studies notice that ASICs optimized for Earth cooling can not merely be transplanted into area and anticipated to final years.

Knowledge reveals terrestrial mining advantages from low-cost native electrical energy, proximity to upkeep groups, and economies of scale which can be already effectively understood. Placing those self same miners in orbit removes easy accessibility for repairs.
If a board fails, a alternative may require one other rocket launch. That threat elements into any calculation of lifetime prices and return on funding.
