The fact that the cold, dry Mars of today had flowing rivers and lakes several billion years ago has puzzled scientists for decades. Now, Harvard researchers think they have a good explanation for a warmer,

Mars' southern hemisphere absorbs a lot of the sun's energy during the Red Planet's spring, and that may be causing Mars' dust storms, a new study suggests.

Images of Mars taken from orbit show thousands of mounds in a region sculpted by water billions of years ago. A robotic mission may investigate the area one day.

The northern plains of Mars, marked by thousands of mounds and hills, hold significant evidence of the planet's watery past.

Data collected by NASA's InSight lander suggest that ancient internal processes are responsible for the "Martian dichotomy" that splits the Red Planet into two distinct halves.

Buttes and mesas in Mars' Chryse Planitia contain clay minerals made from liquid water interacting with the rock nearly 4 billion years ago.

"Rootless cones form when lava flows over wet or icy ground, causing it to boil and explode," said Dundas. "The region around Athabasca Valles is covered by a huge lava flow field, and seeing rootless cones on that lava tells scientists that there was ice underground but very close to the surface when that lava erupted."

In his prepared remarks, Trump, a longtime backer of U.S.-led space exploration and exploitation, singled out Mars and left the moon hanging.

The findings are the result of the ongoing studies performed by NASA’s Curiosity rover, which has been scouring the red planet since landing in 2012. The latest breakthrough came as scientists were able to analyse ripples on Mars' surface that signified the presence of ancient lake beds.

During his inaugural address, President Donald Trump said he wants 'American astronauts' on Mars. Where does a future Mars mission currently stand?

Groundbreaking research into Mars' energy balance reveals a polar surplus driving dynamic weather patterns, including massive dust storms, offering clues to its climate stability. Scientists at the Un

The European Space Agency (ESA) wants to develop key technologies for a Mars surface lander by the mid-2030s.
