There is no sea on Mars

The discovery of sediment deposits in the Meridiani Planum area on Mars by Opportunity robot has long been seen as indisputable evidence of the presence of oceans and lakes on the planet's surface in time. long.

However, according to US researchers at the Massachussetts Institute of Technology, these layers of sediment may have been left when the water moving on the red planet has evaporated.

To arrive at the conclusion, researchers have created models that demonstrate that there is a water system on Mars. According to the analysis, Meridiani is an area where sediment layers may have deposited due to the evaporation of liquid volume.

The origin of this liquid may be due to rain creating layers of underground water. The water then evaporated due to the formation of the Tharsis volcanic chain.

University of Arizona researcher Victor Baker wondered if these underground water layers contained living things similar to Earth in the Rio Tinto region, southeastern Spain. .
