There is ice on the surface of the moon

The presence of water on the moon, but in the basement was already known. However, NASA researchers have shown that ice water is also present on the surface of our natural satellite, 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 satellite of the earth, in craters where the sun's rays do not penetrate. The temperature never exceeds about -150 degrees Celsius. "With enough ice on the surface, over a few millimeters, the water might become a source of future exploration or to keep expeditions to the moon, possibly more easily accessible than the water that is beneath the moon surface," NASA says.

The researchers obtained the evidence thanks to an instrument sent in 2008 aboard an Indian probe, and that directly measures how ice molecules absorb infrared light. "This is the first time scientists have received irrefutable evidence of the presence of ice-cold water on the surface," said lead author Shuai Li of the Institute of Geophysics and Planetology of Hawaii.

Will men return to the moon soon?

According to him the only way to know if this water can be misused by humans is by sending robots to take samples. NASA & # 39; s plan is 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 restored by Apollo mission astronauts a few decades ago. in the sixties.

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.
