Sophia selects Spherical for Athena power systems (opens in a new tab)Manual review 29 Oct 2026. Compared the August 24 Sophia supplier release, Q4 2027 target, Spherical relationship and saved TILE architecture. Athena remains a planned shared-computing demonstration with passive radiative cooling and a tailored EPS and battery architecture. Numerical compute, memory, power and thermal limits are not disclosed, and the separate Apex demonstration is not assumed to be Athena. Primary body last observed 23 Oct, 00:40 UTC. Source monitoring: ongoing. Source collection and substantive profile review are separate checks. Plans and dates may change.
