Mars Had An Ocean 4.3 Million Years Ago

Mars Had An Ocean 4.3 Million Years Ago

(Reported by ScienceAlert)

Mars once held more water than the Arctic Ocean

And it would have been ideal for alien life.

Scientists at NASA have measured signals from ancient water on Mars to estimate that 4.3 million years ago, there was probably enough water to cover the entire Martian surface in a layer about 137 meters deep. More likely, this water accumulated in an ocean bigger than the size of Earth’s Arctic Ocean, covering almost half of Mars’s northern hemisphere. This means at its deepest point it would have reaching down to more than 1.6 kilometers. And yep, that’s about as much water as you’d need to make an ideal environment for life.

“Our study provides a solid estimate of how much water Mars once had, by determining how much water was lost to space,” lead researcher Geronimo Villanueva, from NASA’s Goddard Space Flight Centre in the US, said in a press release. “With this work, we can better understand the history of water on Mars.”
