Description

technical field [0001] The invention relates to an environment simulation device, in particular to a Martian dust storm environment simulation device, which belongs to the field of aerospace. Background technique [0002] Deep space exploration is one of the hot development directions of human space activities in the future. Mars is the planet closest to the Earth in the solar system. It is considered to be the only planet where life may exist among the eight planets in the solar system. It is also the first choice for manned deep space exploration besides the moon. Human exploration of Mars has never stopped. Since the 1960s, the United States, Russia, Europe, Japan and India have successively launched Mars exploration missions. In October 2019, China's Mars probe made its first public appearance, named "Mars-1", and is scheduled to launch in 2020. [0003] In order to meet the needs of experimental research on the Martian environment, verify theoretical analysis, and num...
