China's Tianzhou-9 cargo spacecraft and its Long March-7 Y10 carrier rocket have been positioned at the Wenchang Spacecraft Launch Site in Hainan Province, marking a critical step toward resupplying the nation's space station. The vertical transfer of the fully assembled rocket-cargo combination signals final preparations for liftoff, with pre-launch checks and joint tests now underway.
Next-Gen Rocket Capabilities
The Long March-7 rocket, powered by kerosene and liquid oxygen, represents China's commitment to reliable and eco-friendly space technology. Standing 53.1 meters tall with a 14-ton low-Earth orbit payload capacity, it has successfully launched all previous Tianzhou missions. Wang Xi of the China Aerospace Science and Technology Corporation (CASC) emphasized its precision: "The rocket can recalculate its flight path in real-time, achieving orbital insertion within four seconds of target – like a celestial navigation system."
Emergency Readiness & Scientific Payload
A backup rocket stands ready to address potential emergencies within three months if required. The Tianzhou-9 carries 6.5 tonnes of supplies, including upgraded domestically developed spacesuits rated for 20 spacewalks over four years – a 33% durability improvement. A new core muscle training device aims to combat microgravity health risks, while experimental equipment promises advancements in space science research.
This mission supports the upcoming Shenzhou-20 and Shenzhou-21 crewed missions, reinforcing China's growing capabilities in sustained orbital operations.
