Chinese space travelers aboard the Shenzhou-19 mission successfully produced rocket fuel and oxygen using semiconductor catalysts. The technology mimics plant photosynthesis to convert carbon dioxide and water into ethylene (a spacecraft propellant) and oxygen. This breakthrough could pave the way for future interplanetary missions by utilizing in-situ resources for breathable air and fuel.
, space travel ers from the current Shenzhou-19 mission produced the necessary ingredients of rocket fuel , as well as oxygen, another useful resource in space. The team used semiconductor catalysts to turn carbon dioxide and water into oxygen and ethylene, a hydrocarbon commonly used to produce spacecraft propellants, according to the"This technology mimics the natural photosynthesis process of green plants through engineered physical and chemical methods, utilizing carbon dioxide resources in confined spaces or extraterrestrial atmospheres to produce oxygen and carbon-based fuels," state-run news broadcasterThe experiment could lay important groundwork for our efforts to turn in-situ resources in faraway places into a source of breathable air and rocket fuel that future interplanetary space travel may require.
Experts have generally found that electrolysis is too energy intensive for long-distance space travel. By using semiconductor catalysts instead, Chinese researchers hope to convert carbon dioxide at both room temperature and standard atmospheric pressure, thereby requiring far less energy. However, details regarding the experiments remain slim, and it's still unclear just how feasible the concept actually is, especially in extremely remote and hostile landscapes like the surface of Mars. But if confirmed, the concept could give future Chinese space explorers a major leg up. The country is hoping to build aby 2035, an endeavor that will require a steady and reliable source of breathable oxygen — not to mention rocket fuel for the trip back to Earth.
