Mars, by virtue of its tenuous atmosphere and proximity to our solar system’s asteroid belt, is far more vulnerable than Earth to being struck by space rocks – one of the many differences between the two planetary neighbors. Scientists are now gaining a fuller understanding of this Martian trait, with help from NASA’s robotic InSight […]

Scientists are using data from NASA’s Curiosity rover to measure the total organic carbon in Martian rocks for the first time. Organic carbon is a key component in life molecules. There is evidence that the red planet’s climate was similar to Earth billions of years ago, with a thicker atmosphere and liquid water that flowed […]

NASA’s Perseverance Mars rover has captured an unexpected image, that of a shiny piece of foil stuck on a rock on the red planet. The piece of foil is part of a thermal blanket that may have come from the descent stage of the rocket that landed the rover and the Ingenuity Mars helicopter on […]

This image of Aonia Terra, an upland region in the southern highlands of Mars shows a 30 kilimetre-wide which is nestled within a landscape of winding channels. Resembling veins running through a human eyeball, these channels are likely to have carried liquid water across the surface of the red planet around 3.5-4 billion years ago. […]

We observe ancient shorelines, indicating the presence of a large standing body of liquid water, but little to no erosional activity in the form of rivers/valleys. We observe rock deposits from tsunamis that occurred in the past; but tsunamis would not have been possible had the ocean been completely frozen. This paradox has been under […]
