💨 Abstract

The NASA Mars rover Curiosity has found siderite, an iron carbonate mineral, in rock samples drilled at three locations in Gale crater. The mineral's presence suggests that Mars once had a carbon dioxide-rich atmosphere which could have warmed the planet and sustained liquid water. This discovery provides evidence of Mars' warmer and wetter ancient past and could potentially indicate that it harbored life. The samples contained up to 10.5%
