NASA’s Curiosity rover discovered a Martian crater lake from three-and-a-half years of observations. A new study based on this discovery suggests that the ancient, now non-existent Martian lake may have been the stronghold of various forms of microbes.
Researchers state that environmental conditions in the lake differed from one part to another. Thus, different areas of the lake were conducive to support different forms of microbes. Previous research validated the presence of lakes on the Red Planet over 3 billion years ago in Mars’ Gale Crater.
The latest study, however, details the chemical conditions that subsisted in the lake and also uses the Curiosity’s payload to understand if the lake was stratified or not.
Ancient Martian Lake Supported Life?
Scientists and researchers are far from confirming whether Mars hosted life. However, they are looking for signs of life that could have existed on the planet. They believe that to find if life pre-existed on any planet, one needs to first rebuild the environment to ascertain whether it was capable of supporting life or not.
