China Sea-based Ceres-1S Rocket Launches Four Commercial Satellites

Galactic Energy's fifth Ceres-1S carrier rocket, Ceres-1S Y5, launched four Tianqi satellites (Tianqi 34-37) for its "Beautiful World” Mission from a sea platform located near Shandong Province, China, on May 19, 2025, at 07:38 UTC (15:38 local time). This was Galactic Energy's 19th successful flight. The satellites entered their planned orbits as part of the Tianqi Constellation. The CERES-1S is a sea-launch version of the company's mature rocket model, the CERES-1. The four-stage rocket can carry a payload of about 300 kilograms to a Sun-synchronous orbit at an altitude of 500 km. It can adapt to flexible launch points and landing areas and provide high-quality and low-cost launch services for various types of small satellites.

This a series of Chinese experimental Low Earth Orbit (LEO) comsats for private firm Guodian Gaoke supporting Internet-of-Things (IoT) communications. They each carry a camera for educational purposes. This marks the completion of the first phase of the "Apocalypse Constellation"—China's first low Earth orbit IoT constellation. The Tianqi constellation consists of 38 satellites, plus ground stations. Twenty-five satellites are currently in operation. Once completed for China's Internet of Things information industry.

Guodian Gaoke operates this constellation to provide its users with much-needed data collection and transmission services for terrestrial network coverage blind areas. It supports marine, environmental protection, meteorological, forestry, geological, emergency, rescue and smart city industries to improve China's global data network coverage. It is also being applied to the consumer electronics products market, including mobile phones, cars, walkie-talkies, wearable devices and emergency kits that can be directly linked to these satellites.
