Chinese Researchers Flag 1-Engine Artemis Lander Design as Life-Threatening
1 articles · Updated · South China Morning Post · Jun 13
Summary
A Chinese research team said NASA’s Artemis lunar lander has a potentially fatal single-point failure because one main engine governs descent to the Moon and one main engine is the only way back.
A March peer-reviewed paper in Chinese Space Science and Technology called that architecture a “glaring weakness,” arguing there is no backup if either engine fails during descent or ascent.
China’s team contrasted the U.S. design with China’s lunar lander, which they said includes 3 backup engines, framing the difference as a measure of how each program values astronaut safety.
The critique highlights a broader U.S.-China split in lunar mission design as both countries race to land humans on the Moon.
As China critiques NASA's lander safety, who is truly leading the race for a sustainable presence on the Moon?
Is NASA's single-engine lander a calculated risk for efficiency or a catastrophic oversight in the new space race?

Overview
Chinese researchers have raised serious concerns about NASA's Artemis lunar lander, calling its reliance on a single main engine for both descent and ascent a 'life-threatening' flaw. If this engine fails at any point, the mission could end in disaster, risking both the crew and the entire Artemis program. In contrast, China's Lanyue lunar lander uses a multi-engine system to provide extra safety and redundancy, reducing the risk of a single point of failure. This difference highlights a key debate in lunar exploration: whether to prioritize mass efficiency or crew safety through redundancy.
