The combination of China's Tianzhou-10 cargo spacecraft and a Long March-7 Y11 carrier rocket was transported vertically to the launch site in south China's Hainan Province on Friday, according to the China Manned Space Agency.

Tianzhou-10 will carry nearly 6.3 tonnes of supplies to support the Shenzhou-23 and Shenzhou-24 astronaut crews aboard China's space station. The cargo includes crew supplies, maintenance spares, propellant, new Extravehicular Activity (EVA) suits and a new space treadmill for astronauts' in-orbit exercise.

The mission will also deliver six scientific experiment payloads weighing about 280 kilograms, supporting research in microgravity fluid physics and advanced space technologies.
