WENCHANG, Hainan – On March 12, 2025, a meaningful step was taken in the expansion of China’s commercial space capabilities. A group of 18 satellites was launched into low Earth orbit by a long March-8 Y6 carrier rocket from the Hainan commercial space launch site.
Thousand Sails Constellation Takes Flight
The satellites, identified as the fifth group of their kind, successfully reached their predetermined orbit, according to the China Aerospace Science and Technology Corporation (CASC). These satellites are integral to Spacesail, a Chinese commercial internet constellation. The thousand Sails constellation aims to provide enhanced internet services globally.







First Launch from Launch Area No. 1
This mission marks a significant milestone as the first launch from Launch Area No. 1 at the Hainan commercial spaceport. this follows an initial launch from Area No. 2 on November 30, 2024, demonstrating the operational readiness of both launch areas at China’s premier commercial space launch facility.
Launch Area No. 1: A New Era in Commercial Spaceflight
standing at 83 meters tall, Launch Area No. 1 is specifically designed for the Long March-8 rocket.It features a modular steel structure and incorporates a dual-direction flame deflector cone for cooling and noise reduction. This innovative design enhances rapid reusability capabilities, allowing for a launch and reset cycle of just seven days. This rapid turnaround is crucial to meet the increasing demand for launch services.
The Hainan commercial space launch site’s construction began in July 2022, with its inaugural mission successfully executed in November 2024. Phase II of the project is currently underway, promising further enhancements to the facility’s capabilities.
Long March 8: Powering China’s Space Ambitions
Developed by the China Academy of Launch Vehicle Technology (CALT), a subsidiary of CASC, the Long March-8 is a medium-lift, liquid-fueled rocket known for its cost-effectiveness and ability to perform multi-satellite launches into medium and low Earth orbits.
This launch represented the 563rd flight mission in the Long March carrier rocket series, a cornerstone of China’s space transportation system. The Long March 8 continues to be a reliable workhorse for deploying satellites.
Future Missions
Looking ahead, the Long march 8 is slated for another launch in Q1 2025, carrying the G60 Group TBD mission from Launch Complex-1 at the Wenchang Satellite Launch Center. This upcoming launch is part of the Qianfan series, further solidifying the Long March 8’s role in deploying satellite constellations.
