Amazonian chemical weathering rate derived from stony meteorite finds at Meridiani Planum on Mars
Spacecraft exploring Mars, notably the Mars Exploration Rovers Spirit and Opportunity as well as the Mars Science Laboratory or Curiosity rover, have accumulated evidence for wet and habitable conditions on Early Mars more than 3 billion years ago. Current conditions, by contrast, are cold, extremel...
