China plans to wave its flag on the surface of the moon — literally – National Post
Chang’e 7 mission, slated to reach the moon’s south pole next year, will include a flag that can flutter even in the vacuum of spaceYou can save this article by registering for free here.

So the design included not just an upright pole but a perpendicular extension like a shower curtain rod, so the flag could hang fully unfurled, all its stars and stripes showing.Enjoy the latest local, national and international news.Enjoy the latest local, national and international news.Create an account or sign in to continue with your reading experience.Create an account or sign in to continue with your reading experience.Don’t have an account?

The lab was co-established by the China National Space Administration and the University of Science and Technology of China.The solution, Zhang said, is to arrange wires on the surface of the flag with access to two-way positive and negative current. This will “make the flag flutter through the interaction of electromagnetic fields,” he explained.Zhang added: “This initiative is intended to enhance young students’ understanding of China’s space program and inspire their interest in pursuing space exploration in the future.”The flag will fly aboard the Chang’e 7 mission, which is expected to head to the moon’s south pole next year in search of water ice and other resources in that region. In addition to a lander, a rover and the flag, the mission will include a suite of scientific instruments.Get a dash of perspective along with the trending news of the day in a very readable format.By signing up you consent to receive the above newsletter from Postmedia Network Inc.A welcome email is on its way.

Chang’e 1 and 2 reached orbit around the moon, while 3 and 4 landed and deployed robotic rovers. Missions 5 and 6 returned lunar material to Earth from the near and far side of the moon, and marked the first return of material from the far side of Earth’s natural satellite.“The rover of the Chang’e 7 is slightly larger than that of the Chang’e 4 in scale,” Chang’e 7 Deputy Chief Designer Tang Yuhua of the Lunar Exploration and Space Engineering Centre of China told state television. “It is designed to carry different instruments, and is of roughly the same structure.”Chang’e 8, expected to launch in 2028, is expected to carry a 3D-printing experiment to test-build a lunar structure. It’s all in aid of the nation’s push to land astronauts on the moon, perhaps as early as 2030.“Our goal is to establish a sustainable and scalable comprehensive scientific experimental facility on the lunar surface and in lunar orbit, capable of long-term autonomous operation and short-term human participation, and to basically build an International Lunar Research Station by around 2035,” said Zhang.Of course, every nation’s lunar landers, like the Soviet missions of the 1960s and 1970s, carried some sort of flag or identification. China’s Chang’e 6 mission even carried a flag made of basalt, a type of rock common on the moon, as a way to demonstrate how lunar materials could be used in creating objects locally. (The flag was, however, built and flown from Earth.)Currently, pride of place still goes to America’s space program, which returned striking images of several astronauts saluting the stars and stripes on the lunar surface. And while it’s true that NASA currently has plans to land additional astronauts on the moon as early as 2026, previous slippages in its timeline suggest that may not happen.As to the U.S. flags already there, the one from the first landing, Apollo 11, fell over as the ship blasted off from the lunar surface to begin its journey home. Others were placed farther from the landing sites and have been shown to still be standing in photos taken from orbit, although they may have faded in the harsh environment. China’s waving flag, if it succeeds, could represent a new milestone in the annals of lunar vexillogy (moon flags), at least for now.Postmedia is committed to maintaining a lively but civil forum for discussion.
