Chinese scientists are working on a groundbreaking idea proposed by elementary school students: designing a flag capable of fluttering on the moon’s airless surface. The project, part of China’s ambitious lunar exploration program, highlights the nation’s focus on scientific innovation and inspiring the next generation.
Students’ Vision Sparks Lunar Innovation
The idea originated from students in Changsha, Hunan province, who proposed creating a flag that could wave in the vacuum of space. Researchers at the Deep Space Exploration Laboratory (DSEL), based in Beijing and Anhui province, embraced the creative concept and began developing a payload for the Chang’e 7 mission.

Zhang Tianzhu, deputy director of DSEL’s future technology research institute, explained the challenge: “On the moon, the absence of an atmosphere creates a vacuum, making it difficult for a flag to wave like it does on Earth.”
To overcome this, the students suggested embedding a closed-loop wire on the flag’s surface. By enabling bidirectional currents, electromagnetic field interactions would create the illusion of a fluttering flag. If successful, this payload would be the first to make a flag appear to wave on the lunar surface.
The project, part of a broader scientific outreach initiative, is expected to be completed by February. Zhang emphasized its potential to deepen young people’s understanding of space exploration and ignite enthusiasm for aerospace careers.
China’s Lunar Ambitions
The Chang’e 7 mission, scheduled for launch around 2026, is part of the fourth phase of China’s lunar exploration program. The mission’s primary goal is to search for evidence of water or ice at the moon’s south pole, a region of high scientific interest due to its potential resources.
This mission builds on the success of Chang’e 6, which in 2024 completed the world’s first sample return mission from the far side of the moon. Preparations are also underway for Chang’e 8, slated for a 2028 launch, which will focus on experiments in lunar resource utilization.
These missions are integral to China’s ambitious plans for the International Lunar Research Station (ILRS). By 2035, the ILRS is expected to serve as a hub for engineers, a laboratory for scientists, and a training ground for future deep-space explorers.

The flag project not only embodies technological innovation but also reflects the importance of engaging younger generations in space exploration. By turning a creative idea from elementary students into a tangible scientific experiment, China demonstrates its commitment to fostering curiosity and innovation among its youth.
