American scientists say water ice found at Mars north pole. They accidentally discovered new water ice 1.6 kilometers below the North Pole of Mars. These well-layered mixtures of ice and sand may be the “remains” of the long-lost ancient Martian polar ice caps, which may be one of the largest reservoirs on Mars. one. The latest research is crucial to finding “clues” of life on Mars.
Researchers came to this conclusion based on data collected by NASA’s Mars Reconnaissance Orbiter. The orbiter has been orbiting Mars since 2006 and just completed its 60,000th trip around the planet. The orbiter carries a radar instrument that can see about 2.5 kilometers below the surface of Mars. From this data, the researchers discovered large amounts of ice.
“We didn’t expect to find so much water here,” study lead author Stefano Nerozzi, a doctoral student in geology at the University of Texas Geophysical Institute, said in a statement submitted to the American Geophysical Union. ice, which could make it the third largest reservoir on Mars after the polar ice caps.”
Where there is ice, there is water. A second study by other scientists also supports the presence of large amounts of water ice in the area. The second study used Martian gravity data obtained from several NASA Mars exploration missions. And research shows that if this water ice melted and was evenly distributed around Mars, it would submerge Mars by about 1.5 meters.
What’s even more interesting is that the water ice here is not pure ice, but a mixture of alternating ice and sand. The team found that in some places, the sand and ice are 90 percent water.
If the discovery holds up, these layers of ice and sand may be the “remains” of the ice caps that covered Mars’ polar regions hundreds of millions of years ago. They could also demonstrate that the Martian climate warms and cools based on small changes in its orbit and tilt.
The researchers pointed out that the new study will also help scientists map the water sources of Mars, which is crucial for finding “clues” of life, because if there is life on Mars, they are likely to live in water.
In addition, in July last year, another group of scientists published findings saying that there was very salty lake water buried under 1.6 kilometers of ice at the South Pole of Mars.
