# Space data centers tracker: Know who is really putting data centers in orbit, what has flown and what is only talk.

Canonical page: https://spezia.ai/tools/space-data-centers

Every company and government program working on computing in orbit or on the Moon: what has actually reached orbit, what is funded, what is only filed or announced, the money and people behind each, every dated milestone and every slip, and the numbers that decide whether it can ever beat a data center on the ground. Built for investors, the data center and power companies it competes with, and the suppliers selling into it.

- **Part of:** Work the data center build-out
- **Plan:** Ultra. Part of Ultra. A free account opens the whole build-out 3 days a month, so you can see it before you pay.

## What you get

- **Flown, funded or just filed.** Each program ranked by what can be checked: hardware in orbit first, then money raised and milestones met, with every slipped date counted against it.
- **The money and the people.** Every funding round with its leads and valuation, the founders and executives, and their own words on the record, boosters and skeptics side by side.
- **Can it beat the ground?.** Launch cost per kilogram against the break-even, cost per GPU-hour in orbit and on the ground, power, cooling and radiation, each number with its source.

## How it works

1. Open space data centers.
2. Read the programs ranked by what has flown, then open one for its rounds, people and milestones.
3. Check what to watch next, and the economics against the ground.

## Who uses it

- [Investors](https://spezia.ai/for/investors): Venture, growth, public-market and family-office investors
- [Data center contractors, suppliers and developers](https://spezia.ai/for/infrastructure): Contractors and trades, suppliers, developers, utilities and lenders

## Questions

### Where does it come from?

Company announcements and filings, regulator applications, research papers, launch records and named press reports, each read at its source and dated. A company's own claim is labeled as its claim, and a fact from one outlet is labeled as reported.

### How is a plan ranked?

By what can be checked: hardware in orbit counts most, then money raised and milestones met on time. Every date that slipped counts against it. A big target counts for nothing until something flies.

### Does it say whether space data centers make sense?

It shows the numbers both sides use: launch cost against the break-even, cost per GPU-hour in orbit and on the ground, power, cooling, radiation and links, with who says each and when. It does not pick a side for you.

### Which plan includes it?

Ultra, with the rest of the build-out. A free account opens the whole build-out 3 days a month.
