Understanding how air moves across a planet is key to predicting its weather and climate. On Earth, these patterns shape ...

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 have identified another possible commonality between Earth and Mars: a solid inner core. Scientists have ...

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 ...

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 ...
