We know that lakes existed on Mars’ surface billions of years ago. But scientists have debated whether the lakes were open to the air or covered by a layer of ice.
NASA's Curiosity Mars rover viewed these yellow crystals of elemental sulfur using its Mast Camera. The discovery marks the first time this mineral has ever been found in a pure form on Mars.
Among several recent findings, the rover has found rocks made of pure sulfur — a first on the Red Planet.
The mystery of life’s origins on Earth has long puzzled scientists, but a recent discovery on Mars might be shedding new light on this profound question, while also inching closer to finding life on Mars.
New observations of mud cracks made by NASA's Curiosity rover show that high-frequency, wet-dry cycling occurred in early Martian surface environments.
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.
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 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.
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 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.
NASA recently released a 360-degree panoramic image based on images taken by the Curiosity rover, which showed its latest drilling site.
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.
The finding has significant implications for whether life once existed on Mars.
Boron, changing minerals offer evidence of a habitable lake and complex chemistry.
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.
