Here’s the latest dirt on Mars. NASA’s trusty Curiosity rover, which has been exploring the so-called red planet for years, just unearthed something huge — a stash of carbon-rich carbonate minerals ...

Since the carbonate minerals were found beneath the surface of Mars, the discovery suggests that they may be masked by other minerals in near-infrared satellite images of the planet from orbit.

Observations of large valley networks on today’s Mars suggest formation by flowing water. However, most climate models cannot sustain temperatures above freezing. To understand this contradiction, a ...
