China's Mars Sample Return Mission May Involve Helicopter.

China's Tianwen-3 mission aims to collect and return 500 grams of samples from Mars around 2030, using a pair of Long March 5 rockets. The mission objectives include searching for evidence of life on Mars, understanding its environmental and climate evolution, and potential past habitability. The landing segment will have limited capacity to collect samples close to the landing site, using either a six-legged crawling robot or an Ingenuity-like helicopter. The mission will adhere to the highest standards of planetary protection protocols.
