Clay subsoil at Earth’s driest place may signal life on Mars

Earth’s most arid desert may hold a key to finding life on Mars. Diverse microbes discovered in the clay-rich, shallow soil layers in Chile’s dry...

Early Martian landscape probably looked like this image of Devon ice cap

Early Mars was covered in ice sheets, not flowing rivers. Many valley networks scarring Mars's surface were carved by water melting beneath glacial ice, not...

Electrically charged dust storms could shed light on life on MARS

How’s the weather on Mars? Tough on rovers, but very good for generating and moving highly reactive chlorine compounds. New study shows that Martian dust storms,...

Ancient asteroid impacts created life ingredients on Earth and Mars

A new study reveals that asteroid impact sites in the ocean may possess a crucial link in explaining the formation of the essential molecules...

Scientists solve the mystery of lava-like flows on Mars

The mystery of some lava-like flows on Mars has been solved by scientists who say they are caused not by lava but by mud. There...

Scientists establish new timeline for ancient magnetic field on Mars

Mars had a global magnetic field much earlier—and much later—in the planet's history than scientists have previously known. A planet's global magnetic field arises from...

Jezero crater on Mars may harbor signs of life

A new analysis of satellite imagery supports the hypothesis that the Jezero crater on Mars could be a good place to look for markers...

Fleets of ‘nanocardboard’ aircraft could explore Mars

A fleet of tiny “nanocardboard” aircraft could help explore Mars, researchers say. They each weigh about as much as a fruit fly and have no...

These ‘nanocardboard’ flyers could serve as Martian atmospheric probes

This summer, NASA plans to launch its next Mars rover, Perseverance, which will carry with it the first aircraft to ever fly on another...

‘Black beauty’ meteorite reveals watery past on Mars

Mars likely received water from at least two vastly different sources early in its history, according to new research. The variability the researchers found implies...
