NASA: Meteorites can strike the moon and cause water feathers to shoot in space
That's the basic takeaway from a new study announced by NASA challenging our moon perceptions and other rocky orbs out of space.
Micro-meteorites collide with the moon at high speed and send shock waves reverberating through the luner surface. They only need to penetrate a few inches to arouse the water deposits, and the high energy of the collision changes the molecules in water vapor. Plums went out in space. Most molecules violate the enormous environment around the moon, while some settle back to the ground.
The new perspective of our closest neighborhood neighbors is derived from a study published only in Nature Geoscience by scientists from NASA, Johns Hopkins University, and the University of Maryland-Baltimore County.
The author's lead author is Mehdi Benna, a planetary scientist at NASA's Goddard Space Flight Center. He told CNN that success was "giving a big piece of puzzle" what would happen when meteorites contradict other "windless bodies" around our solar system and beyond.
It shows that water is not just locked in the ground, and, according to Benna, has implications for how future humans or robotic explorers can use groundwater resources .
Scientists have thought that meteorites will move the lunar water deposits. Now they know for sure
Benna, who also owns a planetary scientific paper at the University of Maryland-Baltimore County, says that the water is widespread "globally" on the moon. But we do not know much about everyday behavior.
He led companions combining data gathered by the Neutral Mass Spectrometer aboard the Lunar Atmosphere and Dust Environment Explorer (LADEE), a robotic mission orbited Scientists use data from LADEE, a robotic craft moonlight from orbit until 201
Previous lunar probes such as Cassini and Deep Impact show "having an active cycle of water on the moon," wrote Benna and her writings. They decided to study 33 surface water plume, 29 of them are known and four new ones.
Scientists know that the plume of water corresponds to the times when the meteorite stream arrives. And computer molecules have predicted that meteorites can trigger these whirlwinds.
But Benna's team saw something that has not been confirmed before. It was "the first time that it was observed in practice," he said.
And because scientists have confirmed it in an airless body, they can now indicate the same process will happen everywhere, Benna said
Although the water is widespread in the lunar soil, is spreading immensely. The moon is pretty dry. One metric ton of regolith (the layers of loose soil and deposits covering solid rock at the origins of the moon) yields only 16 ounces. of water, the value of an average water bottle.
Study shows that the moon is not too quiet and broken
By showing that the moon is just a static globe, this study gives us a new image of the moon as rocky world life with dynamic geological and chemical processes.
Benna said that she remembered the look of the moon as a boy, and was thinking of the distant, ancient globe as "silent and lost."
But it says studying him, and a million men and women, are a different story.
"What motivates me," says Benna, whose study shows changes in the month, responding to celestial neighbors not decades or centuries, but "over the days and even time. "
"It seems to be tricky," Benna said. "The moon is active."
