China’s Space Program Soars with New Rocket, Lunar Rover, and Launch Site Expansions

China’s ambitious space program continues it’s rapid ascent, highlighted by the successful maiden launch of the Chang Zheng 8A (CZ-8A) rocket on February 11, 2025. This achievement, coupled with ongoing expansions at the Hainan and Haiyang launch facilities and the introduction of the “Tansuo” lunar rover, underscores China’s dedication to becoming a dominant force in space exploration and technology. The CZ-8A’s inaugural flight represents a significant advancement in China’s spaceflight capabilities, incorporating innovative engines and technologies designed to enhance its overall performance and versatility.

CZ-8A successfully launches on Maiden Mission

The CZ-8A rocket embarked on its first mission on Feb. 11 at 17:30 local time (09:30 UTC).the launch originated from Launch complex 201 (LC-201) at the Wenchang Space Launch center. The rocket’s payload included the second batch of GuoWang (“National Network”) communications satellites, destined for low-earth orbit (LEO) as part of the GuoWang constellation operated by SatNet. The first group of these satellites was launched in December by a Chang Zheng 5 rocket.

The GuoWang constellation, supported by the chinese government, is projected to consist of 13,000 satellites. While specific details about GuoWang are less readily available compared to its rival Qianfan (“Thousand Sails”) constellation, both constellations are expected to grow to similar sizes and utilize a flat-packed design reminiscent of SpaceX’s Starlink satellites. GuoWang satellites are expected to operate at an altitude of approximately 1,000 km, nearly double the altitude of Starlink satellites, which orbit between 525 and 570 km.

The CZ-8A, an expendable rocket with a diameter of 3.35 meters, features a larger second stage compared to the Chang Zhang 8 (CZ-8). The upgraded second stage, developed by the China Academy of Launch Vehicle Technology (CALT), is equipped with two lighter YF-75H engines that use liquid hydrogen and oxygen as propellants. CALT plans to use the CZ-8A’s upgraded second stage as a “universal” final stage on all medium and heavy-lift rockets in the future. The first stage of the CZ-8A utilizes YF-100 engines, which are powered by liquid kerosene and liquid oxygen, similar to other Chang Zheng rockets.

Positioned as China’s primary launch vehicle for LEO and medium-Earth orbit missions, the CZ-8A can lift 8,400 kg to LEO or 7,000 kg to a sun-synchronous orbit. The exact number of GuoWang satellites launched on this mission was not officially disclosed.

This maiden flight also debuted a new dual-redundant electrostatic servo mechanism, a technology previously implemented in aircraft like the Airbus A380 and Lockheed Martin F-35 Lightning fighter jet. According to CALT, this lighter mechanism, weighing less then 20 kg, enables more efficient and rapid manufacturing. The chief designer noted that it can operate continuously and addresses conventional aerospace challenges such as heating during ground operations. The mechanism is also compatible with both horizontal and vertical integration and transport modes, the latter of which is used for the CZ-8A.

Chinese Launch Site Expansions Underway

The Wenchang spaceport, specifically LC-201, has been a hub for missions launched by the Chang Zhang 7 and CZ-8 rockets. The adjacent Hainan International Commercial Aerospace Launch Center has recently completed its Commercial LC-1 pad, configured for chang zheng 8 vehicles, though it has yet to host its inaugural launch. The nearby “universal” Commercial LC-2 pad, just 600 meters away, saw the debut flight of the Chang Zheng 12 in late November and is designed to service up to 19 different liquid-powered rockets.

Construction is underway for a second phase at Hainan, which includes two additional launch pads, Commercial LC-3 and Commercial LC-4. These new pads, like Commercial LC-2, will support the newer generation of Chinese liquid-propelled rockets.

The coastal locations of Hainan and Wenchang allow rockets to fly over the South China Sea, mitigating risks to inland villages. These spaceports are also located closer to the equator then China’s older inland sites, providing additional launch trajectories.

Hainan International Commercial Aerospace Launch Co. (HICAL),the launch site’s operator,reports that the new pad developments will cover an area exceeding 133 hectares. The expansion will include a commercial control center, a tracking and telemetry command station, and a new assembly and test building. The center aims to host a launch every month this year and is targeting 20 missions in 2025. Each of the two completed pads is designed to accommodate up to 16 launches annually. HICAL also claims to be able to restore operational readiness within seven days of a launch and facilitate launch readiness using the transport erector. The satellite megafactory is still on track for completion this June.

Drone footage has revealed the new sea-based launch platform, HOS-1, a converted oil rig, which will support offshore launches from the Haiyang Oriental Spaceport. Located in Yantai, the spaceport plans to host 100 launches per year by 2027 and more than 10 launches in 2025. China’s maritime launch capabilities have seen increased activity,with sea launches from OrienSpace’s Gravity-1,Galactic Energy’s Gushenxing-1 (Ceres-1),and Chinarocket’s Jielong-3 in the past year.

The HOS-1 platform is part of the spaceport expansion announced last October, which includes a dedicated launch vessel and two offshore platforms.
