Rare meteorite from Mars gives us a view into its ancient crust

Crater counts tell us that most of the Martian surface is more than 3 billion years old, but pieces of Mars we have on Earth tell a different story. The three main classes of Martian meteorites—shergottites, nakhlites, and chassignites—are all 2.4 billion years old or younger. Un

Mars dust may be less abrasive than lunar dust, spacesuit samples suggest

Tucked away among its sensors, cameras and navigation tools, NASA's Mars rover Perseverance is wearing small swatches of spacesuit material. A rover doesn't need a spacesuit, but the swatches—each less than a square inch (6.5 square centimeters) in size—serve an important purpose
