Latest developments in the Chinese space industry: iSpace and LandSpace gear up for upcoming launches as Chinese spaceplane embarks on another flight mission.

China is ramping up its space activities with a series of high-profile launches and developments in reusable rocket technology. One notable event is the launch of the Chinese Reusable Experimental Spaceplane, also known as CSSHQ, on a Chang Zheng 2F/T rocket. The details of this mission remain unclear, but it is said to involve verifications of reusable technologies and space science experiments. This mysterious spaceplane will operate in orbit for several months before returning to Earth.

Meanwhile, private Chinese companies LandSpace and iSpace are focusing on developing reusable rocket stages with vertical takeoff and landing capabilities. LandSpace has released information about its upcoming ZhuQue-3 rocket, which will be similar in size to SpaceX’s Falcon 9. The rocket will feature stainless steel methane engines and is expected to have a payload capacity of 21.3 metric tons to low-Earth orbit.

LandSpace is also planning to conduct a vertical takeoff, vertical landing (VTVL) test using a hopper vehicle. This test will verify the rockets’ capabilities for takeoff, gimbling, throttle, and steering, similar to prototypes used by SpaceX in the past. iSpace, another Chinese company, has completed its second test flight of the Shuang Quxian 2Y (SQX-2Y) hopper, a two-stage, liquid-methane-fueled reusable rocket. The company plans to use the hopper as a testbed for its future SQX-3 rocket, which will have a payload capacity of up to 8.5 metric tons.

In addition to these developments, China has successfully launched the Yaogan 41 mission using the massive Chang Zheng 5 (CZ-5) rocket. The payload of this mission is described as a remote sensing satellite that will operate in a high orbit. The CZ-5 rocket is China’s heavy-lift rocket, capable of deploying heavy payloads or reaching high-energy trajectories.

Overall, China’s space ambitions are reaching new heights with these launches and developments in reusable rocket technology. As the country continues to expand its space program, it’s positioning itself as a major player in the global space industry.
