Long March 7 is a new generation of medium-sized carrier rocket developed by China's manned space project to meet the launch of cargo spacecraft by China's space station project. Its predecessor is the Long March 2F carrier rocket. The Long March 7 rocket has a total length of 53 meters and adopts a "second-half" configuration. The core first-class and core second-class diameter is 3.35 meters, and the four boosters are 2.25 meters in diameter. It uses liquid oxygen, kerosene and other non-toxic and non-polluting fuels as propellants. The take-off mass The near-Earth orbit (LEO) carrying capacity is 14 tons, and the sun-synchronous orbit carrying capacity of 700 kilometers is about 5.5 tons.

The multi-purpose spacecraft shrinkage return capsule is one of the loads of the first flight of the Long March 7 carrier rocket, which is a reduced version of the new generation of manned spacecraft return capsule. The return capsule is a key product for China's future manned deep space exploration mission developed by the Chinese Academy of Space Technology (the Fifth Academy of Space).
