According to the findings of recent research, Mars, which is often referred to as the “red planet” because of its arid and barren desert, was originally mostly blue and covered with seas.
Researchers have never disagreed over the fact that there was once water on Mars; nevertheless, they have disagreed about how much water was there. According to the findings of recent research, the seas on Earth were around 4.5 billion years ago approximately 984 feet deep.
Researchers from the University of Copenhagen think that their discoveries bring scientists one step closer to discovering an answer to the age-old issue of whether or not there was life on Mars at any point in its history.
In 2007, the twin rovers Spirit and Opportunity operated by NASA discovered signs of water in rocks, which caused Spirit’s wheels to get damaged. The silica-rich layer that was discovered on the scrape on the rover was analyzed by specialists.
A year later, when the Phoenix lander went missing while it was collecting geological samples, experts speculated that the equipment may have had some kind of interaction with ice fragments. After some time, an analysis revealed that the lander had uncovered evidence of water vapor.
According to a story by MailOnline, a different rover called Curiosity was investigating the surface of Mars in 2012 when it conducted research on rocks that had been in contact with liquid water billions of years ago.
New research found that the whole world was once covered by seas, and the depth of those oceans might have varied anywhere from 984 feet (300 meters) to 3,280 feet (1,000 meters). According to Professor Martin Bizzarro, who works at the Centre for Star and Planet Formation, the amount of water on Earth is really rather low in contrast to that on Mars.
According to the professor, the water on Mars was transported there by asteroids that were partially or completely frozen.
