Dear MEL Topic Readers,
Buried lakes of liquid water discovered on Mars
Mars once was a much more habitable planet with an atmosphere, water, and warmer climate, though how warm it was hasn’t been clarified yet. So, scientists have been looking for traces of water that could have harbored lifeforms. Recently, some scientists found four underground lakes near the south pole of the red planet by the data taken from Mars-orbiting European spacecraft. Does that mean Mars colonists don’t need to carry water from Earth? Not likely. The water is thought to be extremely salty, which could refrain water from freezing, and that is why the spacecraft detected underground water, not ice. In fact, highly salt-condensed water could remain liquid at temperatures as low as below -100C. And if the water is that salty, it is not likely for any microbial life to live in, not to mention the extremely cold temperature.
However, we may one day find a trace of living or once-lived lifeform on our neighbor planet.
Enjoy reading the article and learn about what water could mean on the red planet.
