Revision History

Correction: Starcloud-1 was the first satellite to carry an NVIDIA H100, not the first data-center-class GPU in orbit. Also added that the Suncatcher prototype can power only one of its four TPUs at a time, for about 20 minutes per session.

Update: added Google's October 30, 2026 report that the Project Suncatcher prototype returned its first AI response (a Gemma 4 haiku), and Google's own confirmation of four TPUs on board.

Correction: separate Zhejiang Lab's Three-Body constellation from ADA Space's Star-Compute program, update Cowboy Space (Reason-1 launched, FCC record), Lonestar and Axiom Space

Correction: NASA filed its objection to Project Sunrise with the FCC on April 30, 2026 (reported in May), per the FCC record

Correction: Google's Suncatcher prototype launched on October 1, 2026 and is in contact; the Suncatcher paper now has a peer-reviewed version, which gives a 10 krad(Si) maximum tested dose; SpaceX's 12-page FCC reply was filed on September 16, not September 18, and gives satellite mass as under 4,000 kg; Starcloud-1 orbits at about 500 km, not 325 km; re-sourced the September 20 Kinetica-1 flight and added its second computing satellite; corrected a reference title. Also added the FCC's August 28 letters to all five orbital data center applicants, its September 30 environmental-review order, Orbital Compute's July 31 acceptance for filing and ADA Space's October 14 launch.

Improve internal links (2026-10-13)

Correction: Titan schedule table cell matches both releases (verifier V6)

Correction: Space.com article date (verifier V4)

Update: refresh Aethero Titan launch status to September 28, 2026 and attribute the October 2026 (April release) versus 2026 (August release) schedule wording

Correction: attribute conflicting Suncatcher prototype lifetime reports (Ars Technica: a few months; Space.com citing NYT: a year); update launch status to September 28, 2026

Verification fixes (V7): Orbital Compute raised its target to ~250 kW (Sep 10); Chenguang-1 launch date; SpaceX FCC figure; radiation v1/v2 comparison wording; TPU generation attribution; Forethought, Deutsche Bank, Taranis and SemiAnalysis attributions

Correction: AI1 compute payload now listed by SpaceX as up to 250 kW peak/175 kW average (150/120 kW was the June 2026 design, not the current official page); 'not precluded by fundamental physics' quote is from Google's Research blog, not the paper; Suncatcher orbit does not eliminate batteries (Google: 'reducing the need'); Starcloud ran Gemma (Starcloud calls it 'a version of Gemini'), not two models; Starcloud-2 moved to 2027 rideshares; removed unsourced 'first formal pushback' claim for NASA's Sunrise objection; removed garbled SatNews CASIC testbed claim; Kepler hosts, not Axiom nodes, carry multi-GPU modules per SatNews. Update: Suncatcher M1 on Transporter-18 (Oct 1, 2026), paper v2 radiation results, Starcloud $250M at $2.3B, NVIDIA NVL72 Starmind plan, SpaceX FCC debris response, China and Orbital developments to Sep 25, 2026.

Added EnduroSat's August 2026 plan to pre-integrate NVIDIA space-computing hardware across FRAME satellite buses, with explicit future-status, supplier-role, Titan launch-status, and Space-1 availability qualifications.

Correction: Updated the SpaceX AI1 power and late-2027 schedule, replaced obsolete Aetherflux material with Cowboy Space, added the Cowboy and Orbital FCC filings plus Aethero's flown edge-compute missions, qualified launch-cost model inputs and broad first/inventory claims, and preserved the verified ESA study material.

Add the ESA, IBM Research, and KP Labs edge-computing feasibility study, distinguish edge systems from orbital cloud proposals, and clarify simulation, maturity, and preprint status.

Correction: Starcloud-2 launch date updated from October 2026 to January 2027 per SpaceNews (May 26, 2026); China Three-Body constellation second/third-group claim reattributed to ADA Space EVP Zhao Hongjie via China SCIO and the SatNews February 2026 testing claim reattributed to CASIC's separate CubeSat testbed; added supporting references for the 744 TOPS / 1,000 POPS / 2,400-400 figures, the Gigasat Factory and TeraFab claims, and Lonestar's in-transit operations (now attributed to the company); corrected the 5 GW concept attribution to Starcloud, Google's next-nearest-neighbor spacing, the Altman quote wording, the Deutsche Bank row's unverified figures, and Starcloud's total-funding wording.
