Ceres-1 sea-launch Y7 lifted off at 04:10 Beijing time on January 16, 2026, from waters near Shandong. CNSA’s same-day notice, attributed to Our Space, confirms successful insertion of Tianqi Constellation Group 06. Taiyuan Satellite Launch Center conducted the mission, while the actual launch was at sea. Those facts are retained without relocating the flight to a Taiyuan land pad or Wenchang. The disclosed cumulative count is Ceres-1’s twenty-third flight; Y7 identifies this sea-launch vehicle rather than the family’s overall count. The notice does not state the batch’s satellite count, so no number is inferred from other Tianqi groups. Successful launch and insertion are distinct from subsequent commissioning and completion of the wider constellation. Service dates, orbital elements and operational acceptance are not invented. The original January event and source dates are preserved separately from the later historical import.
