Experimental Research on Extraterrestrial Artificial Photosynthetic Technology
Online published: 2025-04-22
Extraterrestrial Artificial Photosynthetic (EAP) technology aims to simulate the natural photosynthesis of green plants in the extraterrestrial space environment, and convert carbon dioxide into oxygen and carbon-containing fuels through physicochemical processes, making it a promising technology for efficient carbon dioxide conversion and oxygen regeneration. This technology can not only convert the carbon dioxide produced by human respiration into oxygen to realize the regeneration of waste in confined spaces and greatly reduce the material supply requirements of manned space station or manned deep space spacecraft, but also utilize the abundant carbon dioxide and water in-situ resources of the extraterrestrial environment such as Mars to produce oxygen and fuel to achieve the extraterrestrial survival of human beings on other planets. This paper comprehensively overviews the recent progresses of extraterrestrial carbon dioxide conversion technologies. It also clarifies the concept and connotation of EAP technology and analyzes its characteristics and application prospects. On this basis, this study first proposes the space experiment objectives of EAP technology, and then presents the design of the experimental payload, relevant ground tests results, and on-orbit experiment progress. Finally, this paper summarizes and prospects the research progress of EAP technology.
