Space missions face logistical challenges when sourcing essential resources from Earth, especially for habitats on the Moon or Mars. One solution lies in the establishment of an artificial carbon cycle on these extraterrestrial sites, modeled after Earth’s carbon cycle. Artificial photosynthesis through photocatalytic CO2 conversion is emerging as a potential method to achieve this.
The artificial carbon cycle, inspired by Earth’s natural process, presents a solution to supplying resources for space missions. Artificialthrough photocatalytic CO2 conversion is a promising approach, but efficiency improvements are needed. Currently, space missions mainly rely on the transportation of basic needs from the Earth. This is extremely challenging and logistically impossible when we aim to develop stations or habitats on extraterrestrial sites such as the Moon andFor example, an astronaut needs almost a kilogram of oxygen per day to sustain their life. Therefore, tons of oxygen have to be transported to build a station at extraterrestrial sites every year, raising the cost and risk of the mission.
It is expected such a situation can be changed by building the artificial carbon cycle on the extraterrestrial sites. On Earth, the carbon cycle allows the carbon atoms to move from the atmosphere (presenting in gaseous carbon compounds such as CO
