In the last three billion years Mars lost a huge amount of water equivalent to the volume of the oceans on Earth. Moreover, this process occurred gradually enough, and thus the planet remained potentially habitable for a long time, scientists say.

Studying the vibrations of the parts of heavy and plain water in the atmosphere of the Red Planet, NASA specialists understand how quickly Mars has been losing water all these years. It was found that 3.7 billion years ago the planet had enough water to cover the entire surface with layer 140 meters depth. And then Mars began to lose water. However, while it is not clear how it happened.
