Thursday's hovering and obstacle avoidance test, which took place in Huailai, northern Hebei province, was conducted in a facility that simulated conditions on Mars. A red platform with steel cables attached mimicked the planet's gravity - which is about a third that of Earth - as the lander descended from a tall, metal structure.

The test is "an important part" of China's plans to land on Mars, said Zhang Kejian, director of the China National Space Administration (CNSA).

"Currently, all development work is going smoothly," he said in a statement. China is pushing to catch up with the United States and become a space power, with ambitions of a manned lunar landing.
