Orbital data centers: questions and sourced answers
Are there data centers in space?
Small ones, yes. As of 3 Oct 2026, 7 tracked projects have computing hardware that has flown: Google: Project Suncatcher: first TPU prototype satellite (4 Google Trillium-generation TPUs; in orbit, 1 Oct 2026, 18:32 UTC (Transporter-18)); Starcloud: Starcloud-1 (1 NVIDIA H100 GPU; in orbit, 2 Nov 2025); Axiom Space: Orbital data center nodes (first two) (commercial off-the-shelf compute with 2.5 Gbps optical links; in orbit, 11 Jan 2026); Axiom Space: Data Center Unit-1 (AxDCU-1) on the ISS (Red Hat Device Edge compute unit; deployed, fall 2025 (deployed to the ISS)); ADA Space and Zhejiang Lab: Three-Body Computing Constellation (first 12 satellites) (on-board AI processors (per-satellite specs not in source); in orbit, 14 May 2025); TakeMe2Space: MOI-1a in-orbit compute satellite (117 TOPS onboard compute, 2 TB storage, nine-band multispectral imager; in orbit, 1 Oct 2026, 18:32 UTC (Transporter-18)); Lonestar Data Holdings: Freedom lunar data center payload (IM-2) (small data center payload with Phison storage; flown, 27 Feb 2025 00:16 UTC (IM-2)). None of them is a full-size data center; each row links its sources on the tracker.

How many orbital data center satellites have been requested from the FCC?
The tracked FCC filings state these scales: SpaceX (with xAI): up to 1,000,000 satellites, 500-2,000 km (FCC application filed 30 Jan 2026); Blue Origin: up to 51,600 satellites in sun-synchronous orbits (FCC application filed March 2026); Orbital: up to 100,000 satellites; 10 GW compute target (FCC request reported 30 Jun 2026; first launch not stated). These are requests, not launched satellites.

What has SpaceX announced about orbital data centers?
Orbital data center constellation (FCC SAT-LOA-20260108-00016): SpaceX asked the FCC for up to one million satellites operating as orbital data centers; announced alongside SpaceX's acquisition of xAI. Timeline as stated: FCC application filed 30 Jan 2026. Starmind AI1: first-generation AI compute satellite: SpaceX's first-generation orbital data center satellite. SpaceX said on 4 Aug 2026 it is partnering with NVIDIA on the AI1 compute payload; NVIDIA's 24 Aug 2026 release says AI1 will be based on an optimized Vera Rubin NVL72 rack-scale system. Musk gave Q4 2027 for the first launch to orbit. The wider constellation is the FCC filing tracked separately. Timeline as stated: Q4 2027 (Musk, 24 Aug 2026); 'significant scale' in 2028.

What is Google's Project Suncatcher?
Project Suncatcher: first TPU prototype satellite: Google's first TPUs in orbit, on a prototype satellite developed with Planet. Launched 1 Oct 2026; Google says it has confirmed contact and the satellite is operating as expected. It will gather data on how the chips handle launch stress, radiation and thermal extremes in low Earth orbit. Status: in orbit (1 Oct 2026, 18:32 UTC (Transporter-18)). Project Suncatcher: two prototype satellites with cross-links: Planet builds and operates two prototype satellites for Google to test TPUs working together over high-bandwidth inter-satellite links. Status: planned (early 2027 (target)).
