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.

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 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.
