A new electrochemical device holds potential to directly split carbon dioxide (CO2) into carbon and pure oxygen. The team ...

Changes in pressure like this are why your ears sometimes pop when traveling between different elevations. Mars has surface pressure just like Earth does, but it's much less significant than ours.

Nuclear pulse propulsion is a technology that would work. It was being developed in the 1960s but it was stopped because of ...

Scientists call these organisms extremophiles, since they can thrive in Earth's coldest, warmest, and high-pressure environments. Sending microbes to Mars violates a key tenet of NASA policy But ...

To mitigate global climate change, emissions of the primary culprit, carbon dioxide, must be drastically reduced. A newly developed process helps solve this problem: CO2 is directly split ...

Lianjie Man and colleagues conducted high-pressure-temperature laboratory experiments to determine the crystal structure and density of the iron-sulfide phase in Mars's core. The authors suggest ...

"She actually created a system that simulated Mars atmospheric pressure," said Tillman, "so it was just like it's like on Mars — temperature, pressure, humidity — all of that in a chamber." ...

As astronauts Butch Wilmore and Suni Williams acclimatize to Earth, the effects of being stranded in space for nine months, ...

This distorts vision and may pose severe risks on deep-space missions, such as those to Mars, where astronauts won’t have quick access to medical care. Ocular pressure fluctuates in microgravity ...
