China’s Tiangong research generates oxygen, rocket fuel in major space exploration leap
Shenzhou-19 astronauts simulate natural photosynthesis, bringing long-haul crewed missions a step closer to reality
A series of experiments on board China’s space station have for the first time produced oxygen and the ingredients for rocket fuel – key steps that are considered essential for human survival and the future exploration of space.
The 12 experiments took place inside a drawer-shaped device, using semiconductor catalysts to convert carbon dioxide and water into oxygen while producing ethylene, a hydrocarbon that can be used to make spacecraft propellants, according to the China Manned Space (CMS) website.
It said the tests focused on several technologies that would be essential for resource production and human survival, including: carbon dioxide conversion at room temperature; the precise control of gas and liquid flows in microgravity; and real-time, high-sensitivity detection of reaction products.
“This technology mimics the natural photosynthesis process of green plants through engineered physical and chemical methods, utilising carbon dioxide resources in confined spaces or extraterrestrial atmospheres to produce oxygen and carbon-based fuels,” state broadcaster CCTV reported on Sunday.
“The work is expected to provide critical technical support for human survival and exploration in outer space,” the report added.
