CHINESE SCIENTISTS BUILD AMARS ATMOSPHERE MODEL
WORDS ANDREW JONES
Chinese scientists have constructed a numerical model to simulate the Martian atmosphere and assist the country’s plans to collect rock samples from the Red Planet. The model replicates the cycles of dust, water and carbon dioxide in Mars’ atmosphere. It will be used to simulate meteorological conditions for landing spacecraft, including surface temperature, wind and dust. China plans to launch its Tianwen-3 Mars sample-return mission between 2028 and 2030. A lander will collect up to 500 grams of Martian material using a drill and a robotic arm. An ascent vehicle will then blast the precious cargo back into Mars orbit, to meet up with an awaiting orbiter for the long journey home.
