Early Mars Had a Sustained, Cyclic, Possibly Seasonal, Climate

New observations of mud cracks made by NASA's Curiosity rover show that high-frequency, wet-dry cycling occurred in early Martian surface environments.

Curiosity rover discovers water-rich fracture halos on Mars

A recent study finds that the vast subsurface fracture networks in Gale crater would have provided water-rich and radiation-shielded conditions that were potentially more habitable than those on the surface.

Mars rover data indicates ancient megafloods

Raging megafloods, likely triggered by the heat of a meteoritic impact, roared across Gale Crater near the equator of Mars some 4 billion years ago, creating gigantic sedimentary ripples visible today.

NASA's Curiosity Rover Detects Spike in Methane on Mars

NASA's Curiosity rover discovered "startlingly high amounts of methane in the Martian air" on Wednesday in what could potentially be a sign of life on the Red Planet, the New York Times reported on Saturday.

Curiosity confirms clay deposits on slopes of Mount Sharp on Mars

Clay often forms in the presence of water – a key ingredient for the evolution of life as it is known on Earth – and Curiosity’s latest findings add more evidence that a significant amount of water once pooled and flowed in Gale Crater on Mars.

Curiosity drills into clay unit; InSight ‘mole’ tests continue

Curiosity Mars rover has started drilling into a clay-bearing unit on the lower slopes of Mount Sharp, while the InSight's mole ran into a sub-surface obstacle of some sort on 28 February after hammering its way just 30 cm into Martian soil.

A 360-Degree View Around Curiosity on Mars

NASA recently released a 360-degree panoramic image based on images taken by the Curiosity rover, which showed its latest drilling site.

Martian dust storm grows global

A storm of tiny dust particles on Mars has prompted NASA's Opportunity rover to suspend science operations. The Martian dust storm has grown in size and is now officially a 'planet-encircling' (or 'global') dust event.

Scientists have found organic molecules on Mars

The finding has significant implications for whether life once existed on Mars.

Curiosity finds tantalizing clues as it ascends Martian mountain

Boron, changing minerals offer evidence of a habitable lake and complex chemistry.

Ancient Mars could have been more like Earth than we thought

The Curiosity Rover discovered manganese oxides on the red planet. The seemingly simple find actually has mind-boggling implications: ancient Mars could have been a lot more like Earth than we thought.

Curiosity Is Using Sweet New Tools to Explore Martian Sand Dunes

Curiosity is busy poking and prodding the Bagnold Dunes, learning some new tricks in the first-ever interplanetary fieldwork on a sand dune. And of course it looks absolutely stunning while doing it in this latest sand dune selfie.
