Aboard China’s Tiangong space station (the name means Heavenly Palace), scientists are offering a glimpse of the future. In a recent demonstration, Chinese astronauts operated a series of experiments ...

Eco-friendly alternatives to fossil fuels are venturing beyond Earth—and into space.

Shenzhou-19 astronauts simulate natural photosynthesis, bringing long-haul crewed missions a step closer to reality.

Astronauts on China's Tiangong station used artificial photosynthesis to turn CO₂ and water into oxygen and rocket fuel.

The 12 experiments carried out at the Tiangong space station focused on key technologies such as the conversion of carbon dioxide at room temperature.

Space is the only place where rocket fuel could be more precious than water ... such as electrolysis on board the International Space Station, which is used to turn solar energy into a supply ...

They have successfully conducted experiments that mimic photosynthesis, converting carbon dioxide and water into oxygen and rocket fuel ingredients ... Shenzhou-19 crew aboard the Tiangong space ...

The trials verify that the fuel can survive ... hydrogen gas thrown into the bargain. Any conventional nuclear fuel would have trouble standing up to that but what the rocket engineers need ...
