We already knew there was a lot of water on the moon, especially in the basement, but NASA scientists confirmed the presence of ice water on the surface on Tuesday, making the potential available for future astronauts. This observation, which has been published in detail in the American scientific journal PNAS, adds to several studies on the presence of water on the moon.
The ice is located on the north and south poles of the earth's natural satellite, in craters where the sun's rays do not penetrate. The temperature never exceeds about -150 degrees Celsius.
"With enough ice on the surface, a few millimeters, the water might become a source of future exploration or accommodation expeditions to the moon, possibly easier to reach than the water detected under the moon surface," NASA says.
The researchers obtained the evidence with an instrument sent in 2008 on board an Indian probe, which directly measures how ice molecules absorb infrared light.
"This is the first time that scientists have received irrefutable evidence of the presence of ice water on the surface," says lead author Shuai Li of the Institute of Geophysics and Planetology, AFP. Hawaii.
According to him, the only way to know if this water can be misused for the man is robots to take samples. NASA plans to send people back to the moon for the first time since December 1972.
Already in 2008, researchers had found water molecules in magma that were brought back decades ago by astronauts from the Apollo missions in the 1960s. Last year, researchers concluded that the depths of the moon were rich in water, based on satellite data.
Water is also present on Mercury and Mars. An underground lake with liquid water has recently been discovered on the red planet. (AFP / NXP)
