Deep oceans of magma once sloshed about inside the crust of Mars, seismic measurements taken by NASA's InSight mission ...

Mars, the next frontier in space exploration, still poses many questions for scientists. The planet was once more hospitable, characterized by a warm and wet climate with liquid oceans. But today Mars ...

Just north of Mars’ equator lies a 45 km (28 mi) wide impact crater known as Jezero Crater. Scientists believe this location ...

Making Mars Earthlike is not impossible in principle, but the scale of mass, heat, oxygen, and energy required makes it far beyond current capability.

Mars wasn't always the cold desert we see today. There's increasing evidence that water once flowed on the red planet's surface, billions of years ago. And if there was water, there must also have ...

Seismic data collected by NASA suggests the amount of water hidden in the red planet's crust would cover its surface in a global ocean. Evidence is mounting that a secret lies beneath the dusty red ...

Research published late last year indicated “seismic discontinuities in the Martian crust” that scientists believe could be an indicator of liquid water under the Martian surface, raising the ...

Mars is tantalizingly similar to Earth in many ways, but especially in its surface features, which often resemble Earth deserts to an eerie degree. Both Earth and Mars share features such as valleys; ...
