Life on Mars ain’t just a song. For a long time, humans have been investigating life forms on the red planet, and it still remains the most intriguing dilemma for planetary scientists.
Well, progress has been made as new research from Mars scientists suggests water flowed on the red planet 2 billion years ago, that’s approximately 1 billion years later than researchers supposed. According to Bethany Ehlmann, a planetary scientist and the associate director of the Keck Institute for Space Studies at the California Institute of Technology, “Mars had habitats for longer than we thought.”
A vivid image was captured by NASA’s satellite the Mars Reconnaissance Orbiter and provides evidence of the fact that the red planet had habitats for longer than believed, illustrating the dried-up channels and depressions containing deposits of salt.
Ehlmann clarified that one of the biggest pieces of evidence of water melting from snow on hills and then flowing down is the salt deposits are downslope from higher elevations. The scientist strongly believes that “they had to come from snow and ice.”
Scientists are convinced Mars was once a world with blue oceans, just like our planet, but there is no information on whether any life grew in those watery areas on Mars.
