Deep Dive
- StarCloud successfully launched a satellite with an NVIDIA H100 GPU into orbit.
- This marks the first deployment of such a powerful terrestrial GPU operating in space, a prototype 100 times more powerful than previous space computers.
- Starcloud 1 was launched on November 2nd via SpaceX's Bandwagon 4 rideshare mission, aiming to test modern data center hardware in orbit.
- Co-founder Philip Johnston's background spans software engineering, applied math, and theoretical physics.
- StarCloud's inspiration stems from societal demand for energy and the slow pace of terrestrial infrastructure development.
- The company pivoted from exploring space-based solar power to orbital data centers due to launch cost adjustments.
- Break-even launch cost calculations were revised from $50/kg to $500/kg, making orbital data centers a more feasible concept.
- StarCloud rapidly developed its first demo satellite in under two years, showcasing significant prototyping speed.
- The co-founders possess complementary expertise, including extensive data center and SpaceX experience, and a decade in satellite design for missions like NASA's Lunar Pathfinder.
- They designed and built the satellite structure, compute module, and payload entirely in-house.
- StarCloud achieved a significant milestone by having a satellite design built, ready, and tested in just 15 months.
- This timeframe is notably faster than the approximately four years typically required for similar startups.
- The rapid progress was facilitated by intense work and in-house development of the compute module and antennas.
- The first satellite, Starcloud 1, is a 60kg payload the size of a small fridge, featuring an NVIDIA H100 GPU.
