Thanks @YCombinator for documenting @Starcloud_Inc1’s journey to launching the first @Nvidia H100 in space 🙏 Check it out below! 🎥🤓
Starcloud (@Starcloud_Inc1) recently made history by launching a satellite with an NVIDIA H100 into orbit — the first time a GPU that powerful has ever operated in space. It's the first step toward building AI data centers in orbit, powered by continuous sunlight and cooled by radiating heat into deep space.
Their approach could one day rival the world's biggest data centers while using less energy, zero fresh water, and far lower emissions.
YC's @aaron_epstein visited Starcloud's HQ, where co-founders @philipjohnston, @EzraFeilden, and @Adi_Oltean explained how they built a working prototype in just 15 months — and why big tech is racing to space for AI compute.

Encyclopedia Cosmologica is an interactive artwork I’m building with @bot . It'll launch to Alpha Centauri with
@FermiExplorer in 2029, contains 5000+ piece of scifi art about advance civilization. Inspired by Jon Lomberg and Carl Sagan
Thanks @PhilipJohnston

Really fun @NoPriorsPod with @goodwin_ml founder of @fractile_ai
topics:
- how to win the ai chip market, structurally
- ai for chip design, what’s compressible
- the need to be a frontier lab to serve frontier labs
- solving memory bandwidth
- new hardware scaling laws
