TL;DR
- Starcloud, an orbital data center startup backed by Nvidia, plans to launch a spacecraft later this year capable of running Bitcoin mining hardware in orbit.
- The company says ASIC mining chips are far cheaper per unit of power than GPUs, making them a strong candidate for space-based computing workloads.
- If the experiment works, solar-powered mining infrastructure in orbit could open a new frontier for Bitcoin’s global computing network.
Bitcoin mining may soon move beyond Earth’s surface. Starcloud, a startup focused on building orbital data centers, plans to deploy specialized hardware that will mine Bitcoin in space once its second spacecraft enters orbit later this year. The initiative tests whether operating mining equipment outside Earth’s atmosphere can offer economic and energy advantages compared with traditional ground-based facilities.

Bitcoin Mining Economics In Orbit
According to Starcloud CEO Philip Johnston, the economics of space computing favor the use of application-specific integrated circuits (ASICs) rather than general-purpose graphics processors. These chips are designed specifically for the calculations required to secure the Bitcoin network.
Johnston explained that GPUs used for artificial intelligence workloads are significantly more expensive per unit of power than ASIC miners. A high-end GPU consuming around 1 kilowatt of electricity can cost about $30,000, while a mining ASIC using similar power may cost around $1,000.
This difference makes Bitcoin mining an attractive workload for orbital computing systems. Mining operations run continuously and require large amounts of electricity, which Starcloud plans to generate through solar panels attached to its satellites. Solar energy in orbit operates without many of the transmission losses or land-use limitations seen on Earth.
The company also points out that Bitcoin mining already consumes about 20 gigawatts of power globally. Moving part of that demand into orbit could reduce pressure on terrestrial energy grids while creating a new type of digital infrastructure industry.
Space Infrastructure And Bitcoin Mining Expansion
Starcloud launched its first satellite in November carrying an Nvidia H100 GPU, marking one of the most advanced computing chips ever placed in orbit. The mission tested whether high-performance computing hardware can operate reliably in the harsh conditions of space.
The startup was founded in 2024 with the goal of building large-scale orbital data centers capable of supporting artificial intelligence and high-performance computing. Its long-term vision includes a constellation that could eventually involve tens of thousands of satellites connected into a distributed computing platform.
The idea of extending crypto infrastructure beyond Earth has also attracted interest from technologists studying interplanetary communications for digital assets. Some researchers have explored whether Bitcoin transactions could travel through satellite and deep-space relay networks in the future.
