Blue Origin has announced a significant step towards sustainable space exploration.
The US space tech firm has revealed a system capable of extracting oxygen from lunar soil.
It's a development that could dramatically reduce the cost and complexity of missions to the Moon and beyond.

Blue Origin's Air Pioneer reactor converts lunar regolith – the dusty material covering the Moon’s surface – into breathable oxygen using high-temperature processes.
The breakthrough addresses one of the most costly challenges in spaceflight: transporting resources such as air and fuel from Earth.
The technology builds on a process known as molten regolith electrolysis, in which lunar dust is heated to release oxygen bound within minerals.
Scientists have long recognised that lunar regolith contains abundant oxygen, but extracting it efficiently has remained a major technical challenge.
The oxygen is chemically bound in oxides, requiring energy-intensive processes to release it.
The generator is part of Blue Origin’s broader Blue Alchemist programme.
Vice president of advanced concepts and enterprise engineering Pat Remias explains: "Blue Alchemist changes everything about how we approach space. It is the foundation for a sustainable robotic and human presence across the Solar System.
"Each kilogram of oxygen we make on the lunar surface is one less that we have to launch from Earth, making it a giant leap toward permanent settlements as well as critical resources for transportation to the Moon, Mars and beyond."
