The **Long March 8A** rocket, known for its advanced technology and capabilities, made its debut on **February 11, 2025**, marking a significant milestone for China's aerospace program. This launch was particularly important as it sent a second group of satellites into **orbit** for the Guowang megaconstellation project, a national initiative aimed at enhancing satellite communications and internet services.
Overview of the Launch
The launch took place at **4:30 a.m. Eastern Time (ET)** from the Wenchang Satellite Launch Center, which is strategically located on Hainan Island. The **China Aerospace Science and Technology Corporation (CASC)** confirmed the success of the mission approximately an hour after liftoff. This launch is seen not only as a technological achievement but also as a stepping stone towards China's ambition of establishing a comprehensive satellite internet service.

Launch Details
| Attribute | Detail |
|---|---|
| Time of Liftoff | 4:30 a.m. ET |
| Launch Site | Wenchang Satellite Launch Center, Hainan |
| Payload | Guowang satellite group (number not disclosed) |
| Launch Vehicle | Long March 8A |
| Mission Goal | To enhance satellite internet service coverage |
Guowang Megaconstellation Project
The **Guowang project**, also known as **SatNet**, is part of China's broader strategy to create a vast constellation of satellites capable of providing internet access across the globe, particularly in underserved regions. The initial launch, which used the more powerful Long March 5B, successfully placed **10 satellites** into orbit. However, specific numbers for the satellites deployed in this recent launch have not yet been disclosed.
The secrecy surrounding the project has led to speculation regarding the capabilities and specifications of the satellites. Notably, there are **ongoing discussions** and concerns related to the **transparency** of satellite functions and operational purposes.
Technical Specifications of Long March 8A
The **Long March 8A** serves as an upgrade over its predecessor, the standard Long March 8, which first flew in December 2020. The enhanced rocket retains essential first-stage mechanics while implementing a new 3.35-meter diameter hydrogen-oxygen second stage. This upgrade enables a larger payload fairing of **5.2 meters in diameter**.
| Parameter | Value |
|---|---|
| Length | 50.5 meters |
| Liftoff Mass | 371,000 kg |
| Liftoff Thrust | 480 tons |
| Payload Capacity (700 km SSO) | 7,000 kg |
Future Prospects for Long March Series
The Long March 8A's versatility is underscored by its potential to support high-frequency launch schedules. With modular construction and increased production capabilities of the **YF-100 engines**, China is poised to achieve remarkable launch cadences. This series of rockets is expected to play a pivotal role in launching various satellite constellations, including both the Guowang and the **Thousand Sails** initiative.
Furthermore, CASC is aiming for nearly **100 launches** in 2025, with significant missions slated, including crewed missions to the **Tiangong space station** and the highly anticipated **Tianwen-2** mission which will undertake a sample return from a near-Earth asteroid.
Conclusion
The successful launch of the Long March 8A underscores China's commitment to expanding its capabilities in space exploration and satellite technology. As the nation continues its ambitious journey towards building a robust satellite network, international observers are keenly analyzing the technological advancements and strategic implications of China's growing presence in outer space.
