Level 1 — Absolute Beginner
Big companies want to build data centers in space.
Data centers need a lot of power for AI.
Space has strong sunlight and cold temperatures. This can help computers work.
SpaceX, Google, and companies from China are working on this idea.
- data center
- a building or place full of computers
- satellite
- a machine that flies around Earth in space
- orbit
- the path an object takes around Earth
- power
- energy used to run machines
- sunlight
- light that comes from the sun
- cool
- not hot; low temperature
- space
- the area outside Earth's air
- plan
- an idea for what to do in the future
Level 2 — Elementary
Several large technology and space companies are planning to build data centers in orbit around Earth.
They want to do this because artificial intelligence needs huge amounts of computing power.
SpaceX asked the U.S. government for permission to launch as many as one million satellites for this purpose.
Google, Starcloud, and companies in China are also working on similar projects.
- artificial intelligence
- computer technology that can learn and make decisions
- application
- an official request, often written
- permission
- official approval to do something
- constellation
- a large group of satellites working together
- infrastructure
- the basic systems and structures a project needs
- radiation
- energy that can be harmful to electronics or living things
- maintain
- to keep something working well
- competition
- when different groups try to do something better than each other
Level 3 — Intermediate
A growing number of technology and aerospace companies are racing to place data centers in orbit as artificial intelligence's demand for computing power continues to surge.
On January 30, 2026, SpaceX filed an application with the U.S. Federal Communications Commission requesting permission to eventually launch up to one million orbital data-center satellites at altitudes between 500 and 2,000 kilometers, projecting that roughly 100 gigawatts of AI computing capacity could eventually result.
Google has partnered with Earth-imaging company Planet Labs on Project Suncatcher, while the startup Starcloud envisions a constellation of 88,000 satellites, and China's main state space contractor has outlined a five-year plan for gigawatt-class space digital-intelligence infrastructure.
Despite the appeal of continuous solar power and the cold vacuum of space for cooling, engineers still face unresolved challenges such as thermal management, remote maintenance, radiation exposure, and orbital debris.
- surge
- a sudden and large increase
- altitude
- height above Earth's surface
- capacity
- the maximum amount something can produce or hold
- envision
- to imagine or plan for the future
- vacuum
- a space completely empty of matter, such as air
- thermal management
- the process of controlling heat in a system
- debris
- scattered pieces of waste or broken material
- unresolved
- not yet solved or settled
Level 4 — Advanced
As artificial intelligence's appetite for computing power outstrips what terrestrial power grids can readily supply, a widening field of technology and aerospace firms is turning its ambitions skyward, wagering that orbit itself could become the next frontier for data-center construction.
SpaceX crystallized that ambition on January 30, 2026, filing an application with the U.S. Federal Communications Commission seeking eventual authorization to launch as many as one million orbital data-center satellites at altitudes ranging from 500 to 2,000 kilometers, a buildout the company projects could ultimately deliver on the order of 100 gigawatts of AI computing capacity.
Rivals are pursuing parallel bets: Google has joined Earth-imaging firm Planet Labs on the aptly named Project Suncatcher, the startup Starcloud has sketched a constellation of 88,000 satellites, and China's principal state space contractor has committed to a five-year roadmap for what it calls gigawatt-class space digital-intelligence infrastructure, setting up a transpacific contest with Elon Musk's ventures.
The pitch rests on orbit's near-continuous sunlight and the cold vacuum of space as a natural coolant, yet the engineering remains far from settled: thermal dissipation, remote servicing of hardware with no on-site technicians, cumulative radiation damage to electronics, and an already crowded debris field all stand as unresolved obstacles, even as the broader industry braces to pour an estimated $650 billion to $700 billion into data-center infrastructure of every kind in 2026 alone.
- outstrip
- to grow faster than or exceed something else

- cumulative
- increasing or growing by successive additions over time
- obstacle
- something that blocks progress or makes it difficult
