Mars had dry and wet eras and dried up for good 3 billion years ago

Astronomers suspect that the comet most likely never passed close to a star, making it an undisturbed relic of the cloud of gas and dust it formed from

New findings could be critical in understanding the climate of early Mars

The Air Force Research Laboratory's new Deployable Structures Lab tests scientific equipment before it's launched into space

These features, which are not found on Earth, are believed to be carved into the Martian surface by dry ice changing directly from solid to gas in the spring

Radio observations of a cold, dense cloud of molecular gas reveal more than a dozen unexpected molecules
