Chinese scientists are developing the capability to build a moon base made of bricks formed from lunar soil.
A recent video from China Central Television (CCTV) shows an animation of a robot working to construct a lunar habitat known as a “moon pot vessel.” Alongside the videos, scientists are conducting concrete experiments to make the moon habitat a potential reality.
The Tianzhou 8 resupply mission launched toward China’s Tiangong space station on Nov. 15 with a range of bricks made from lunar soil simulant among its cargo.
Transporting things to the moon is immensely expensive and challenging, so using materials already present on the moon, known as in-situ resource utilization, offers a way to greatly save costs. Using lunar regolith to make bricks could transform the possibilities for constructing lunar habitats.

The test bricks will be placed outside Tiangong to be exposed to cosmic rays and large temperature changes for three years. The bricks were made with five different simulated lunar soil compositions via three distinct sintering methods, in order to assess their degradation over time and which could provide the best solution for a habitat.
“Back in 2015, when we started exploring whether 3D printing could be used to build a lunar base and what materials could be used, it felt like a fantasy that is incredibly distant,” said project leader Ding Lieyun, of the Chinese Academy of Engineering. “But as we keep working, our understanding has deepened, and we have realized that it is not just our team making efforts. Scientists from all over the world are tackling this challenge together.”
“For example, when it comes to energy issues, some experts told us, ‘You don’t need to worry about energy. There are specialized teams working on that. You’ll just use their results when the time comes,'” Ding said. “That realization has served as a big step forward. This is why interdisciplinary collaboration is so important. When these forces come together, they create something truly extraordinary.”
Ding’s team is working on various challenges such as materials, structure and requisite technology.
Lunar soil has been found to be a mix of rock fragments, minerals, glassy particles and other materials, varying from region to region across the surface of the moon. On Earth, volcanic ash from…
