NASA’s Curiosity rover is providing new insights into how Mars transformed from a potentially habitable planet, abundant in liquid water, to the inhospitable landscape seen today. Researchers discovered that carbon-rich minerals found in Gale Crater indicate extreme evaporation and suggest the planet’s climate could support only transient liquid water.
