About 300 to 500 plants would produce the right amount of oxygen, but it’s much harder to estimate the amount of carbon dioxide the plants absorb, especially if every time a person breathes out ...

The ability to generate oxygen through photosynthesis -- that helpful service performed by plants and algae, making life possible for humans and animals on Earth -- evolved just once, roughly 2.3 ...

Oxygen can be produced on Mars by electrolysis, but how will this potentially life-giving electrolysis method act in reduced gravity?

NASA-backed scientists have created a novel oxygen production system for space. This system uses magnets instead of heavy ...

The microbes generate and release so much of what the researchers call “dark oxygen” that it’s like discovering “the scale of oxygen coming from the photosynthesis in the Amazon rainforest ...

The agency plans to produce a version of the machine that could be flown to the Moon and operated there. A single unit would produce around six tonnes of oxygen a year—though bigger generators ...

An international research team’s plasma-based method to generate oxygen on Mars could have implications for climate change on Earth.

A proposed process to make oxygen and fuel on the moon requires water, carbon, and chemical catalysts taken from lunar soil.

While Earth's slowdown is not noticeable on human timescales, it's enough to work significant changes over eons. One of those ...

In January 2025, the Shenzhou-19 crew carried out 12 experiments in a drawer-sized device using semiconductor catalysts to convert carbon dioxide and water into oxygen and hydrocarbons ...

How Do Oxygen Sensors Work? Oxygen sensors are a key part of the vehicle emissions system. They measure the differential oxygen levels between the outside air and the exhaust gas to generate a voltage ...
