Starcloud-1

Overview

The demonstration satellite that made the case. A 60 kg spacecraft on Astro Digital's Corvus-Micro bus carrying the first data-center-class Nvidia H100 GPU to operate in space, launched November 2, 2025 on SpaceX's Bandwagon-4 rideshare. Within weeks it had run Google's Gemma model and trained nanoGPT in orbit, and it now runs inference on Capella Space radar data. One Nvidia A6000 GPU aboard failed during launch.

In orbit and operating since November 2025, running AI workloads and customer Earth-observation data.
