three to four billion years in the past, it was heat sufficient on Mars to spark main rainstorms and flowing water, which might have frozen shortly after, a brand new research has discovered. This might function proof that easy life might have developed on Mars at an identical time that it developed on Earth.
It’s not new info that Mars was as soon as dwelling to an abundance of water. But it surely has remained considerably of a thriller whether or not the water on Mars was principally liquid or frozen as ice, and the way this will have modified over time. Hotter temperatures on Mars wouldn’t solely signify the presence of liquid water, hotter situations additionally make it extra doubtless that life might have shaped independently on the planet.
One new research compares patterns on the floor of Mars made by mineral deposits with comparable patterns on Earth in all kinds of environments in places together with the Oregon Cascades, Hawaii and Iceland. The Earth information was in comparison with Martian mineral information collected by the Curiosity rover and the NASA CRISM spectrometer, which is presently aboard the Mars Reconnaissance Orbiter circling the planet.

By analyzing these patterns, scientists discovered proof that Mars had a minimum of one lengthy interval of extreme rainstorms and flowing floor water which was adopted by temperatures that froze this water.
“If that is so, it is crucial within the seek for potential life on Mars,” Briony Horgan, a co-investigator on the Mars 2020 mission who offered this work on the Goldschmidt Geochemistry Convention in Barcelona, Spain earlier this week (Aug. 19), mentioned in an announcement.
“We all know that the constructing blocks of life on Earth developed very quickly after the Earth’s formation, and that flowing water is crucial for all times’s growth. So proof that we had early, flowing water on Mars, will enhance the possibilities that easy life might have developed at across the identical time because it did on Earth,” she added.
This research is a stepping stone to understanding the historical past of water on Mars and the way the planet’s local weather has modified over time. However, whereas it provides to proof that situations on Mars might have been able to supporting life at sure factors all through the planet’s historical past, there may be nonetheless a lot to find and discover.
NASA’s Mars 2020 mission goals to deal with key questions surrounding the seek for life on the Pink Planet. Set to launch in July, 2020, and land on Mars in Jezero Crater, the Mars 2020 rover will gather information that might assist the findings on this research.
“We hope that the Mars 2020 mission will be capable to look extra intently at these minerals, and start to reply precisely what situations existed when Mars was nonetheless younger,” Horgan mentioned.
