5th September 2024 – (Beijing) China has announced plans to execute its Tianwen-3 mission, aimed at returning samples from Mars, through two launches scheduled around 2028. The details were revealed by Liu Jizhong, chief designer of the Mars sample-return mission, at the 2nd International Deep Space Exploration Conference held in Tunxi, Anhui Province.
The primary objective of the Tianwen-3 mission is to search for signs of life on the Red Planet. To achieve this goal, Chinese engineers face several technological challenges, including sample collection on Mars’ surface, launching from the planet, and rendezvousing in Martian orbit. Liu emphasised the importance of planetary protection to prevent contamination of both Mars and Earth during the mission.
The mission comprises 13 phases, utilising both in-situ and remote-sensing detection methods. Liu assured that China is committed to adhering to international conventions and implementing measures to safeguard against contamination throughout the mission.
Additionally, the Tianwen-3 mission will feature payloads developed in collaboration with international partners. Liu noted that China aims to work with scientists globally to conduct joint research on the Martian samples and the data collected.
Looking ahead, China plans to collaborate with other nations and research institutions to define mission requirements, analyse concepts, and achieve key technological advancements necessary for establishing a research station on Mars.
