Summary
Google's Project Suncatcher, announced on October 30, 2026, was recorded as reaching the stage of a first Gemma 4 response from a single TPU in orbit. Satellite power is 1kW and only 1 of 4 TPUs runs at a time for about 20 minutes; no figures for speed, cost or lifetime were presented.
A/B Impact Analysis
This record is filed as neutral. There are as yet no measurements of speed, cost or lifetime — the figures that would decide whether orbital computing can move beyond a proof of concept into real capacity — so it counts neither as support for Scenario A, in which the compute bottleneck eases, nor as evidence against it. At this scale there is no basis for comparison with ground-based capacity. The watch judgement recorded it the same way: an early proof of concept with no timeline impact.
