The signal
Early experiments have tested computing hardware in space, and some startups are raising money for orbital data centres. None operate at meaningful scale.
Where it could lead
If practical, it could relieve pressure on Earth’s grids. But getting heat out of equipment in space and moving data back to Earth are major challenges.
Evidence that would strengthen the case
- Demonstrations showing competitive cost per unit of computing
- Solutions for cooling and communications at scale
- Paying customers beyond experiments
What could prevent it
- Launch, cooling and repair costs are too high
- Ground-based energy solutions scale faster
- Space debris or regulatory limits
