A new scenario seeking to explain how Mars' putative oceans came and went over the last 4 billion years implies that the oceans formed several hundred million years earlier and were not as deep as once thought.
The world's most powerful rocket, SpaceX's Falcon Heavy, blasted off Tuesday on its highly anticipated maiden test flight, carrying CEO Elon Musk's cherry red Tesla Roadster toward an orbit near Mars.
New research published in Nature Astronomy seeks to understand how surface clay was formed on Mars despite its cold climate.
Researchers using NASA's Mars Reconnaissance Orbiter (MRO) have found eight sites where thick deposits of ice beneath Mars' surface are exposed in faces of eroding slopes.
When searching for life, scientists first look for an element key to sustaining it: fresh water.
Planetary scientists from Brown University have proposed a new scenario for the formation of ancient clay minerals on Mars that, if shown to be true, could rewrite the early history of the red planet.
Dark features on Mars previously considered evidence for subsurface flowing of water are interpreted by new research as granular flows, where grains of sand and dust slip downhill to make dark streaks, rather than the ground ...
Mars has an invisible magnetic "tail" that is twisted by interaction with the solar wind, according to new research using data from NASA's MAVEN spacecraft.
In a drying time, Mars may have been kept warm enough for liquid water to remain stable on the surface thanks to explosive bursts of methane gas, a new study finds.
