The cold propulsion system of Tiandu-2, an experimental communications and navigation technology satellite, is working well, marking the first on-orbit application of a 3D-printed storage tank in China, the China Aerospace Science and Technology Corporation said. .

The cold propulsion system recently provided high-precision orbital attitude control for the satellite during lunar orbit, marking the first successful application of the liquid ammonia cold air micropropulsion system in the field of deep space exploration.

The development team of China Aerospace Science and Technology Corporation has mastered a series of key technologies to connect the components inside the storage box through 3D printing, which has greatly shortened the development cycle and effectively reduced the cost.
