Satellite data can be expensive and slow to send to Earth before analysis.
Spacecraft computing has used far less capable hardware.
Starcloud says the H100 ran a version of Gemini and trained nanoGPT after launch.
What was shown, and what wasn’t
Shown · verified in the source
Starcloud confirms H100, Gemini and nanoGPT; it does not confirm Gemma.
Documented resultThe company dates launch to November 2025 and the model work to December.
Not shown · limits
- Claimed / not established hereEconomics and environmental advantages remain company projections.
- NVIDIA's October 2025 report said Gemma was planned; the reviewed post-launch page says Gemini. Cost, cooling and solar claims need separate lifecycle evidence.
Bright editorial interpretation
The mission gives a specific technical event to inspect, rather than a generic orbital-data-center promise.
