Beating the US: China’s Quest to Bring Martian Samples Back Home with Tianwen 3 Mission

The Tianwen 3 spacecraft, set to launch around 2030, has the potential to make China the first country to successfully bring Martian samples back to Earth. Wu Weiren, design director of China’s Lunar Exploration Program, expressed confidence that China could beat the US in this endeavor. Speaking at the China Space Conference in Wuhan, Hubei, Wu announced that China plans to launch the Tianwen 3 spacecraft on a mission to retrieve Mars samples.

In addition to the Tianwen 3 mission, China has already begun planning the construction of the world’s first Mars sample laboratory. Key technology for the Tianwen 3 mission is ready, and progress is moving forward smoothly, according to Sun Zezhou, a colleague of Wu Weiren and design director of the 2021 Thien Van 1 Mars mission.

While both China and the United States have successfully landed on Mars, China’s entry into Mars exploration is relatively recent compared to NASA’s decades-long history of Mars exploration. Despite NASA’s early lead in the race to bring back Martian samples, budgetary constraints have complicated their plans. The cost of the program has surged from $4 billion to $11 billion, potentially delaying the return of samples to Earth until after 2040 unless alternative solutions are considered.

China’s successful deployment of the Thien Van 1 spacecraft in 2021 marked a significant milestone in their Mars exploration efforts. With plans for
