Starcloud, backed by Nvidia, successfully trained Google's Gemini LLM, named Gemma, in low Earth orbit using an Nvidia H100 GPU on the Starcloud One satellite. This achievement highlights the potential for space-based data centers to address the energy demands of AI.

Starcloud aims to build a 5-gigawatt data center in orbit, reducing energy costs to below 1 cent per kilowatt-hour. The company plans to launch the equivalent of the entire US power grid's capacity annually within 10 to 20 years. They addressed technical challenges related to radiation and orbital debris, ensuring the operational stability of their infrastructure.
