According to a recent study, Mars, which is known as the red planet due to its vast, arid desert, was once primarily blue and ocean-covered.
Although scientists have long believed that Mars formerly had water, they have disagreed about how much.
According to a recent study, there were 984-foot-deep oceans covering Mars 4.5 billion years ago.
Researchers from the University of Copenhagen think their discoveries help answer the age-old puzzle of whether life has ever existed on Mars.
The identical NASA rovers Spirit and Opportunity discovered water traces in rocks that damaged Spirit’s wheels in 2007. The silica-rich layer discovered on the rover’s scratch was examined by specialists.
Scientists hypothesized that the Pheonix lander came into contact with ice when it vanished a year later while collecting geological samples.
A further evaluation supported the lander’s detection of water vapor.
According to MailOnline, in 2012, another rover named Curiosity was investigating the Martian surface and studying rocks that had once been submerged in water billions of years ago.
A recent study found that the oceans covered the entire Mars and could have been as deep as 984 feet to 3,280 feet.
According to Professor Martin Bizzarro of the Centre for Star and Planet Formation, Earth actually contains a lot less water than Mars.
“This water was brought to Mars by asteroids filled with ice,” according to the professor.
