Mars’ Water was Mineral-Rich and Salty

Methodology to reconstruct water chemistry One of the clay minerals, smectite, can trap ions in water through ion exchanges in the presence of water. Even after loss of water, smectite records ion compositions within interlayers of its structure. Credit: Nature Communications

New study finds surface waters on early Mars may have been habitable for microbial life. Presently, Earth is the only known location where life exists in the Universe. This year the Nobel Prize in physics was awarded to three astronomers who proved, almost 20 years ago, that planets are common around stars beyond the solar system...

Wet Paleoclimate of Mars revealed by ancient Lakes at Gale Crater

 

Mars appears to have had a more massive atmosphere billions of years ago than it does today, with an active hydrosphere capable of storing water in long-lived lakes. The MSL team has concluded that this water helped to fill Gale Crater, the MSL rover Curiosity’s landing site, with sediment deposited as layers that formed the foundation for the mountain found in the middle of the crater today.

Curiosity has been exploring Gale Crater, which is estimated to be between 3.8 billion and 3.6 billion years old, since August 2012. In mid-Sept 2014, the rover reached the foothills of Aeolis Mons, a 3 mile high layered mountain aka “Mount Sharp”. Curiosity has been exploring the base since then...
