**News Content:**
_Xi’an, April 8 (Xinhua) —_ The China Aerospace Science and Technology Corporation Sixth Academy (CASC Sixth Academy) announced today that the propulsion subsystem of the TianDou-2 satellite, a key component of the Chang’e lunar exploration program, is operating stably and has successfully achieved high-precision orbit attitude control in space. This milestone signifies a significant breakthrough in China’s application of 3D printing technology for deep space exploration.
It is reported that the liquid ammonia cold gas micropropulsion system aboard the TianDou-2 satellite features a crucial component — the tank — which was manufactured using cutting-edge 3D printing technology. This innovative approach has not only enhanced the structural performance of the tank but also significantly reduced manufacturing time and costs, paving the way for more efficient and cost-effective solutions for China’s future deep space missions.
Experts from CASC Sixth Academy noted that the successful application of the liquid ammonia cold gas micropropulsion system in deep space exploration marks an important milestone for Chinese space technology. The system enables precise control of minute thrusts, crucial for fine-tuning the satellite’s orbit around the Moon and ensuring its long-term stable operation.
The in-orbit performance of the TianDou-2 satellite has validated the reliability and durability of the 3D-printed tank under the harsh conditions of space, providing strong technological support for future deep space missions, such as Mars exploration and asteroid detection. This achievement not only represents an indigenous innovation of China’s aerospace industry but also constitutes a significant contribution to global space technology.
This breakthrough further solidifies China’s international standing in the space sector, demonstrating the country’s robust R&D capabilities in 3D printing technology and deep space exploration. The CASC Sixth Academy will continue to drive technological innovation, propelling China’s space endeavors deeper into the cosmos.
