Xinhua and other media reported that China conducted a crucial lander full-condition test at the Huailai lunar landing test site. During the test, multiple engines alternated and worked together, playing a significant role in stabilizing the lander.
This test completed the final step of China's manned moon landing in a perfect manner. The most core part is called "full condition." Full condition means boundary tests under different working conditions, including various extreme conditions. For example, during the descent, if there are problems with the engine or navigation, or other issues, how to make the landing smoother through joint control; during ascent, engine ignition and stable operation are also major issues. The developers said very well: "Our only goal is to ensure our astronauts can safely land on the moon and return to Earth."
