"Chinese Scientists Simulate Mars Atmosphere for Sample-Return Missions"

Chinese scientists have developed a numerical model called GoMars to simulate the Martian atmosphere, aiding China's plans for a Mars sample-return mission. The model will help simulate meteorological conditions for spacecraft landing, including temperature, wind, and dust. China plans to launch the Tianwen-3 mission between 2028 and 2030, which will collect Martian rock samples using a drill and robotic arm. The atmospheric model will assist in designing materials suitable for Mars rovers to withstand extreme cold temperatures.
