New Mars Theory Questions Red Planet’s Watery Past

BBC News

The research is published in Nature Geoscience by Prof Alain Meunier from the University of Poitiers, France, and colleagues. It is interesting because it strikes at the heart of the notion that the Red Planet was awash with water, perhaps at its surface, more …

Magmatic precipitation as a possible origin of Noachian clays on Mars

Martian clays were not all formed by the action of liquid water.

Discovered in 2005, the clays of the southern hemisphere of Mars are often considered to be evidence for the existence of liquid water on the planet at a period in the very distant past between 4.5 and 4 billion years ago. However, work carried out by a French-US team led by researchers at the Institut de Chimie des Milieux et Matériaux in Poitiers (CNRS/Université de Poitiers)(1) calls this interpretation into question.

Alain Meunier of the University of Poitiers in France has found that some Mars minerals from the Noachian period are a good chemical match to clays at the Mururoa Atoll in French Polynesia, which formed from cooling of water-rich lava. What’s more, these …

Martian Clay Suggests Planet May Have Been Hotter, Less Wet

Professor Alain Meunier of University of Poitiers, France, a coauthor of the study, said this finding is interesting because it stands in the face of other notions that Mars had a watery past, and forces a rethink of the Red Planet’s early history.

“Mars was not as warm and wet in its earliest time as some have suggested. I do not believe in an early ocean on Mars,” Prof Meunier told Jonathan Amos of BBC News…
