Perth: Scientists have achieved the greatest success in history on Mars. Scientists have discovered the water on Mars that they had been searching for hundreds of years. After this great discovery by scientists, the possibility of life on Mars has increased. Just as water is present everywhere on earth. About 70 percent of the Earth’s surface is covered in water. Water is present in the air, on the surface and inside rocks. Geological evidence suggests that water has existed on Earth for approximately 4.3 billion years. But the history of water on Mars has been very uncertain.
Determining when, where, and for how long water first appeared on Mars are burning questions driving Mars exploration. If life were ever possible on Mars, a certain amount of water would have been needed there. We studied the mineral zircon present in a Mars meteorite and discovered that water was present when zircon crystals formed 4.45 billion years ago. Our results, published today in the journal Science Advances, may provide the oldest evidence of water on Mars.
Mars formed 4.5 billion years ago
The Red Planet was wet It has long been believed that water played an important role in the early history of Mars. To put our results in a broader context, let’s first consider what “early Mars” means in the context of the geological time frame of Mars, and then consider different ways to discover water on Mars. Like Earth, Mars also formed about 4.5 billion years ago. There are four geological periods in the history of Mars. These are the Amazonian (3 billion years ago), the Hesperian (3 billion to 3.7 billion years ago), the Noah (3.7 billion to 4.1 billion years ago), and the Prenoeic (4.1 billion to approximately 4.5 billion years ago).
Evidence of water on Mars was first found in 1970.
Evidence of water on Mars was first found in the 1970s, when NASA’s Mariner 9 spacecraft photographed river valleys on the surface of Mars. Later orbital missions, including Mars Global Surveyor and Mars Express, discovered the widespread presence of “hydrated clay minerals” on the surface. These require water. Martian river valleys and clay minerals are found primarily in the Noah’s Terrain, which covers about 45 percent of Mars. Additionally, orbiters also discovered large drains called “outflow channels” in the Hesperian areas. These indicate the short-term presence of water on the surface, probably from groundwater. Most reports of water on Mars indicate the presence of water in material or terrain more than three billion years old.
When was water found on Mars?
Recently, there hasn’t been much evidence of stable liquid water on Mars. But what happened during the Pre-Noah? When did water first appear on Mars? A look at Mars before Noah. There are three ways to look for water on Mars. The first method is to use observations made by spacecraft orbiting the surface. Another approach is to use ground-based observations, such as those made by the Mars rover. The third way is to study Martian meteorites that fell to Earth, which we did. In fact, the only pre-Noah material we have available to study is found in meteorites from Mars. Of all the meteorites that have fallen to Earth, some come from our neighboring planet. An even smaller group of these meteorites, thought to come from the impact of a single Mars asteroid, contain pre-Noah material.
The ocean exists on Mars
It was also suggested that Mars may have had an early global ocean 4.45 billion years ago. The broader picture of our study is that magmatic hydrothermal systems were active during the early formation of the Martian surface 4.45 billion years ago. It’s unclear if this means the water was stable on the surface at the time, but we think it’s possible. It is clear that the surface of Mars, like Earth, had water on its surface shortly after its formation, an essential ingredient for habitability. (The conversation)
