Neden Önemli?
The descent and ascent stages of a lunar mission rely on a single main engine, with no backup. This design choice is highlighted as a significant weakness.
Yazı boyutu
On the descent stage, one main engine controls the entire fall from lunar orbit to the surface. On the ascent stage, one main engine is the only ticket home.
If that one engine fails, there is no backup. This design, to quote a peer-reviewed paper published in the journal Chinese Space Science and Technology in March, “contains some glaring weaknesses”.

- What are the specific backup systems in the US space program?
- What is the US response to China's engine design?
