According to NASA’s Mars Reconnaissance Orbiter ( MRO), Mars had rivers and water billions of years ago.
MRO has acquired information that Mars had water flowing through it around 2.5 billion years ago.
The shape of certain valleys provides a hint that water flowed on Mars.
Salt Deposits found recently provide the first mineral evidence, confirming river water flowed on the red planet.
Water on Mars is not similar to water on Earth.
Here, water is a combination of two hydrogen atoms and one oxygen, but on Mars, it has Co2 mixed with it.
Water on Mars has evaporated a long time ago and there is no evidence of life. On Earth, where there is water, there is life.
